Robbie Ott, the head machinist at CFH Racing runs the machine shop. He discussed the transition to Hurco machines after we installed our flagship Hurco VMX42i mill and a TM8i lathe. Ott also elaborated on the possible benefits he expects when the shop adds the Hurco VMX42SRTi 5-axis machine.
"I especially like using the Hurco when building prototypes. Just recently we built prototype damper parts. And like with most prototypes, we did not succeed the first time. Hurco gave us the flexibility to make modifications quickly and easily without starting from scratch.Hurco and HSM Works solid modeling allowed us to build these extravagant and complicated parts that would not have been possible on the manual machine," concluded Ott.
Lou Ferriero was working in a plastics vacuum forming house when he identified a market that wasn’t being served. When he started PlasTech Machining and Fabrication Inc., he had one employee (himself) and one manual machine. Today, PlasTech has nine employees, six vertical machining centers, one 5 axis machining center, three turning centers, and Ferriero is thinking about upgrading to a multi-tasking turning center with live tooling and a sub-spindle.
With more than 35 years of experience in the machining and fabrication of plastics, Ferriero is proud that 80 percent of PlasTech’s business is from repeat customers. Approximately 50% of his business is devoted to medical equipment.
“We focus on high quality and precision. We don’t waste time trying to be the cheapest machine shop out there. Our prices are usually in the middle of the road compared to our competitors. We are the best at what we do and pride ourselves on delivering quality parts on time.” It appears PlasTech’s focus on quality versus price is working. According to Ferriero, companies that shipped jobs overseas for cheaper rates have started bringing the business back to PlasTech. “We lost jobs to overseas suppliers about five years ago and most of that work has come back,” said Ferriero.
A big part of PlasTech’s success is due to Ferriero’s commitment to stay current with technology by investing in new equipment. As PlasTech has grown, so has his investment in Hurco machine tools and Hurco technology. His latest investment in a Hurco software feature called UltiMotion continues to provide benefits beyond Ferriero’s expectations. As an example, Ferriero cites a part used for head restraints on hospital beds. “When we machined the parts on our RoboDrill, it took 30 minutes per part. On our Hurco with UltiMotion, it takes 20 minutes and the surface finish quality improved significantly,” says Ferrierro.
UltiMotion is able to simultaneously decrease cycle time and increase surface finish quality due to the underlying motion control algorithm Hurco developed that uses software-based motion instead of conventional hardware-based motion. UltiMotion software has rapid cornering capabilities that allow the spindle to travel through corners at high speed with negligible deviation without overshooting or stopping. Therefore, cycle time is significantly reduced when machining parts with complex geometries and/or repetitive tasks, such as drilling and tapping. Customers with UltiMotion also see improvement in surface finish because UltiMotion minimizes vibration, which results in smoother motion overall.
Flexible Control that Supports NC and Conversational
While PlasTech finds the conversational programming of the integrated Hurco control extremely useful to quickly make a fixture, Ferriero says he uses the NC side of the control for all of his jobs. Keeping his CAM system current is another technology investment that Ferriero continually makes to keep his company up to speed. PlasTech uses Mastercam X5 Cad /Cam software with Mill Level 3 and solids, Mastercam Lathe, verification software, Solidworks, and E2 Shop Systems for shop control.
The Power of Five
Like many prudent job shop owners, Ferriero’s latest machining center investment was a Hurco VM10U 5-axis machining center instead of a traditional 3-axis machine. The VM10U is part of the integrated trunnion style 5-axis machines from Hurco. With X/Y/Z travels of 21x16x19 and a 20-station ATC, the VM10U is one of the highest value 5-axis machines on the market.
Ferriero bought the VM10U to cut down on setups and has realized numerous productivity benefits. "The Hurco VM10U has exceeded our expectations. It has cut down on cost, time, labor and material," said Ferriero.
He cited a specific example for an article that appeared in Manufacturing News. The job entailed the manufacture of plastic components for prototype parts for de-icing the C-130 aircraft. "Without the VM10U 5-axis machine this would have been nearly impossible to get done on time for our customer," said Ferriero. "After offline programming, the setup time on the machine was done in a few hours. The part surface quality and time comparison was much better than expected. It would have been a minimum of 2 days just to make fixtures to machine these parts on a 3-axis machine."
Beyond the technology, beyond the equipment, Ferriero says he continues to invest in Hurco machining centers because of the high quality service he gets from Hurco and Hurco’s distributor, Brooks Associates. Says Ferriero, “The service we get from Hurco and Brooks is second to none. They listen and they are responsive. They understand that your machines are your business.”

Once the beta test began at M-Tech Lab in Indianapolis for a new Hurco software feature, cycle time was cut by 30% and machine jerk was virtually eliminated. President and M-Tech founder Tom Miller said he seeks speed versus accuracy for the type of machining M-Tech does. “We are builders of custom orthotics...We focus on throughput and speed. With UltiMotion we’re seeing 30-35% faster throughput,” said Miller.
The majority of the orthotics M-Tech machines are custom designed to a person’s foot, but all of them are elliptical in shape and have contours throughout. UltiMotion handles such complex geometry easily because the spindle can cut very fast in a smooth elliptical motion. The secret to UltiMotion is the advanced trajectory algorithm in the software that generates significantly faster yet smoother motion than conventional motions systems that rely on hardware. Controlling motion with software versus hardware is theoretically a simple idea, but development of UltiMotion was a complex and comprehensive project with the best software engineers in the world pushing the envelope of motion control. The advancements in motion control are so significant that Hurco was awarded a patent for UltiMotion with several other patents pending.

“We are also currently working on additional designs for the other sports. So watch out rugby fans.”
In the last three years, the number of Hurco vertical machining centres on the shop floor at Tool & Gauge, Co Sligo, Ireland, has trebled to six, and the mould- and tool-maker has also invested in computer-aided engineering software from Pro/Engineer, SolidWorks and Delcam.
Installation of a Hurco vertical machining centre (VMC) in the toolroom at the Ross-on-Wye factory of rubber mouldings manufacturer, Wye Valley Precision Engineering, has resulted in much faster availability of mould tools compared with when the company was using a manual-tool-change CNC mill. A typical middle plate in P20 tool steel is now programmed and machined in six hours, whereas the same job used to take a week. Said machine operator, Matthew Griffiths, "Programming was very time-consuming using our previous machine because the control system did not accept the DXF file output from our CAD system. So after a mould was designed, I had to program every feature manually at the control and the complexity of the tools meant that there was a risk of making errors, which were subsequently difficult to find and correct."This contrasts with the user friendliness of the Ultimax control fitted to the Hurco VMX-24 VMC, installed in April this year (2003). Mr Griffiths advised that the twin-screen CNC system not only reads DXF files directly and automatically generates tool paths from them, but also has powerful on-board software to simplify creation of the entire part program.
Read how this sub-contractor reduced machining time from 60 minutes to 8 minutes by switching from 3-axis to 5-axis.
The installation of two new Hurco machining centres has allowed Lancashire subcontractor, A&G Precision, to attract more work and produce components more efficiently in fewer set-ups.
The company is a leading producer of complex components used in key military and civil aircraft programmes. It is also active in other sectors, principally defence, marine, petrochemical, motorsport, rail and pharmaceutical engineering.In addition to batch production of high-precision components, A&G provides a range of additional services including prototyping, sub-assembly manufacture and reverse engineering.
Brett Mitchell and Darren Withers founded their new company, RP Tooling, as recently as June 2005. Yet by September 2010, turnover had grown to the point where they were able to move out of a rented industrial unit in Halesowen and purchase a freehold property nearby. The two partners, who now employ 20 additional staff, put their success down to following the market and targetting industry sectors that are buoyant at any given time. For example, three years ago a majority of work was for the aerospace industry whereas presently, moulds for automotive customers account for half of throughput.
During 2011, 4,000 such seals will be produced in the press shop at Newtownards, which has 17 power presses rated from 35 to 500 tonnes force for subcontract production runs of progression and deep drawn components.
Black Country toolmaker and subcontractor, Cube Precision Engineering, has installed its largest Hurco machining centre to date, a 3,200 x 2,100 x 920 mm capacity, bridge-type, vertical-spindle DCX32. Delivered at the end of May 2012, it is the fifth machining centre from the same supplier to be purchased.
Few contract machinists in Scotland have a modern, vertical machining centre to match the 2,200 x 1,700 x 750 mm capacity of the Hurco twin-column, bridge-type DCX22 installed at the Coylton works of Ayrshire Precision. This was precisely why managing director, Bert Bradford, purchased the machine on spec in February 2011. Since taking the plunge, the company has secured new work in each of its main industry sectors – mining, nuclear and oil / gas.
The first new job to come along was refurbishment of explosion-proof, steel covers for transformers used in coal mines. They are cooled by water flowing through a hollow jacket, the inner surfaces of which need to be roughened to create turbulence and increase heat transfer to the water. These and other plates up to four metres long are machined for the mining sector on the 50-taper DCX22, the larger workpieces requiring two clampings on the 2,100 x 1,600 mm table.
Bowtech Products was established 22 years ago as an importer of products used for underwater applications, but now designs and manufactures its own equipment. Exports currently account for two-thirds of turnover, which has helped to double the size of the business over the last five years and was one of the reasons for the company winning the Subsea UK Global Export Award 2012, sponsored by Scottish Enterprise.
Manufacture of components has historically been subcontracted but is gradually being brought in-house to control costs and quality as well as to shorten lead times from weeks to days. Two CNC lathes and a machining centre from Hurco underpin this activity at Bowtech's production facility on the Kirkhill Industrial Estate in Dyce, near Aberdeen airport.
Over the past few years, there has been a significant increase in research and development activity at medical device manufacturing facilities around Galway, while the same area in the west of Ireland has also seen a surge in the growth of companies in the biosciences field.
“In the fast changing world of computer peripherals, innovative design is the key. Rapidly converting these designs into prototypes requires a high capability machine tool. When compared to the competition, Hurco’s VM machining center won hands down.”
The people at NuCon Corporation are experts when it comes to impellers. More specifically, they are experts in the manufacturing of radial and axial compressors, pumps and turbines, shrouded impellers, expanders, diffusers, and jet engine cases. They’re also experts in 5-axis machining processes used to manufacture those impellers and the aforementioned parts.
Since 1973, NuCon Corporation has used their proprietary Impeller Machining System to machine thousands of configurations as small as 5 mm in diameter up to 73 inches in diameter. The majority of their products are used for marine propulsion and pumps, industrial compressors, and power generation, but they also machine parts for aircraft and rocket engines. NuCon primarily machines stainless steel, but they have experience machining a variety of materials including aluminum, titanium, exotics, and plastics. They can do any blade configuration a customer needs including straight line element, arbitrary blade shape, blisk, an open or shrouded impeller, and an open or closed turbine. Different blade shapes within a single stator/rotor can be accommodated.
NuCon primarily relies on 15 vintage Sundstrand 5-axis machining centers at their 35,000-square-foot facility in Livonia, Michigan to manufacture these complex blade configurations for customers around the world. In fact, there are only a handful of companies capable of serving this niche market. The NuCon crew has upgraded, retrofitted, and refurbished the massive Sundstrand machining centers so they can handle large parts that vary in complexity and weight, with some blanks weighing as much as 11 tons.
Co-owner David Bernhardt says he started shopping for a smaller 5-axis machining center because it didn’t make sense to tie up a large Sundstrand for smaller parts that were up to 22 inches in diameter. While he considered other brands of 5-axis machines, Bernhardt says a demonstration at Hurco’s technology center in Indianapolis sealed the deal and NuCon purchased two VMX42SR machines. “The VMX42SR’s table had the capacity to handle the weight of stainless steel, which is important because that’s the material we use the most,” explains Bernhardt. The VMX42SR’s C-Axis table with a 24-inch diameter can handle up to 1,100 lbs and the machining center is designed with a B-axis swivel head and C-axis rotary table that lets the tool access hard to reach areas faster. The tilting head design is perfect for the swept surfaces and complex contours NuCon routinely machines. Other advantages of the Hurco VMX42SR include 600-block look ahead, up to 600 ipm programmable feed rate, and processing speed up to 2,277 bps.
Hurco was especially honored that NuCon chose Hurco for its 5-axis machining needs of smaller parts considering the collective expertise of the owners and the exacting standards they demand. NuCon owners David Bernhardt and David Stormont know machine tools inside and out: literally. They were machine tool designers in the 60s at the Buhr Company in Ann Arbor, Michigan, a company well known for developing machine tools designed specifically for the automotive industry. Because of the collective expertise of Bernhardt and Stormont, NuCon has successfully developed their proprietary Impellar Manufacturing Software, designed the spindle head for their rotary head machines, and created their own PC-based controllers. They have achieved accreditation for numerous quality programs and implemented verification and inspection programs throughout their operation.
Bernhardt says he is enamored with the motion control on the Hurco and both VMX42SRs have performed perfectly. Beyond the machine, Bernhardt says the phenomenal service network Hurco has established is probably the best he’s seen in his career. “It’s really something you should promote. The knowledge and customer support is outstanding. I even sold a machine to a fellow down the road. He asked me about our Hurcos and I told him about the phenomenal service network you have and the outstanding performance of our machines. This is still an industry that relies on word-of-mouth, which means a company’s reputation for how they treat customers after they have bought the machine is important,” explains Bernhardt.
While Hurco machine tools are often known for their intuitive conversational programming, NuCon uses the NC side of the control exclusively. The integrated Hurco control powered by WinMax includes both conversational and NC programming methods with ISNC and NC Productivity Packages available for enhanced performance. With an enhanced NC interpreter, the recently released WinMax version 8 (WinMax8) is compatible with more CAD/CAM programs than ever. Other additions to the NC side of the control include Tool Review, Transform Plane, Rotary Tangential Velocity Control, Automatic Safe Repositioning, Recovery Restart, and Cylindrical Wrap.
“It really says a lot for us to go to another machine with an alien control when all of the Sundstrands and turning systems we have use the control system we developed. The integration has been seamless and all of the operators picked up the Hurco control quickly,” says Bernhardt.
NuCon also invests in other technology to enhance efficiency, minimize waste, and maintain outstanding quality. Bernhardt says software packages from OpenMind and Predator are useful to his operation because they analyze part programs to achieve maximum machining efficiency.
Bernhardt attributes his company’s success to great customers, great employees, and the drive to continually find ways to increase efficiency while maintaining the highest quality. “The core of our manufacturing philosophy at NuCon has always been to satisfy our customers. The job isn’t finished until the customer requirements are met. We believe in continual process improvement. You always need to look for ways to work smarter even while you’re working harder,” says Bernhardt.
For NuCon, purchasing the Hurco VMX42SRs helped the company work smarter for smaller 5-axis parts.

"All in all, the Hurco was the best bang for the buck and has the least amount of downtimes over other machines."-Damon Weaver, Owner , Xcentric Mold & Engineering
Watch the Xcentric Mold Video
To keep your business competitive in the 21st century you need to be efficient, flexible and demonstrate a quality product. The Weaver brothers in Chesterfield, Michigan have built their business around those requirements. Hurco is proud to be their vertical machining center of choice. Brendan Weaver and Damon Weaver, owners of Xcentric Mold & Engineering, have defined efficiency by creating a process flow system that lets their employees run three to four machines at a time. “One guy can even run five,” boasts Damon Weaver. Xcentric's flexibility extends beyond the types of molds and parts they create. Xcentric is also flexible in the breadth and depth of services they provide.
“We can turn it from concept to a finished part, and do everything in between,” said the Weavers. “We do part design, FDM rapid prototyping, prototype molds, bridge tooling, and do our own injection molding, all under one roof.” Xcentric's main focus is Fast and Accurate turn around prototype molds and parts with in a 5-16 day delivery to the customer. Xcentric has given new meaning to “fast and accurate turn around” in prototyping. The Weavers grew the business from their CAD and Prototype mold making expertise. “What sets us apart today is, we do what we say and say what we do. Customer service is key and we are proactive in the whole process.” Being proficient in solid modeling, we can propose changes to the customer's solid data, from any format and return the data via email. This service saves days off the build, as being part designers and mold makers we can prepare data for mold ability.
Hurco AdvantageXcentric runs one shift, and routinely runs lights out operations to maximize efficiency. In addition to investing in process efficiency, quality certification (ISO 9001: 2000), and talented employees, Xcentric has invested in top-notch equipment. They have 13 CNC vertical machining centers with 10 of them being Hurco models—two VMX24s, seven VMX42s, and a BMC4020. They also feature Roboshot and JSW, all electric molding machines, and their Engineering department features FDM rapid prototyping, Mold Flow analysis, and seven CAD/CAMseats.
Xcentric utilizes aircraft grade aluminum to produce detail-oriented prototype plastic injection molds that require tight tolerances and longevity, usually up to 100,000 pieces or more. The sample of molds and parts displayed include a variety of consumer products and various automotive parts.One of the Weaver brothers' favorite masterpieces complements their interest in fishing. The Rapid Release Breakaway Rod Holders are proudly displayed on the company's sample shelves. Known for being a true breakaway rod holder, the Rapid Release Breakaway rod holder allows the angler to set the hook and remove the rod from the holder in one motion. This product showcases Xcentric's full-line of abilities—they designed the prototype, made the molds, and produced the actual product. SummaryAt Xcentric, Hurco is the preferred vertical machining center. The operators like the ease of use, especially the ergonomics of the control—slanted screen for easy viewing and big buttons. Additionally, the Xcentric owners say the coolant-thru-the-spindle, the wash down system and chip auger, keep the chips out and the machines clean, “because there is no time to stop the machine when we are building molds,” says Weaver. “All in all the Hurco was the best bang for the buck and has the least amount of downtime over other machines”.
For Damon and Brendan Weaver, another Hurco advantage is the man who represents the company in their area. Damon says Fred Braun, of Braun Machinery, is diligent, extremely knowledgeable, and made the decision to go with Hurco an easy one. As the Weaver brothers expand their efficient prototyping services to more companies and industries, Hurco and Braun Machinery will be there every step of the way.
"Having the large-capacity DCX allows us the opportunity to pitch for a lot of new business up to 3.2 meters by 2.1 meters that we could not have previously undertaken."-Steve Holmes, Director, TGM, Preston, Lancashire, United Kingdom
TGM, an aerospace subcontractor in Preston, England, doubled its Y-axis capacity on the shop floor when the company invested in the Hurco DCX32 machining center with a work envelope of 3.2 meters (126 inches) by 2.1 meters (82.7 inches) by 920 millimeters (36.2 inches). With the DCX32, TGM can machine larger airframe components or fixture multiple parts for more efficient production.Nearly half of the components that TGM machines are made from titanium, including wing and fuselage parts, such as longerons for BAE Systems’ Eurofighter Typhoon. The remainder of throughput is aluminum. TGM also does a lot of Airbus wing work in both materials, such as leading and trailing edges as well as main details for delivery to the OEM’s Broughton factory via Tier 1 suppliers. The latest Boeing 737-600 has a backswept wing tip, which TGM manufactures, that yields significantly improved fuel efficiency because of the superior aerodynamics. Boeing has decided to retrofit similar wing tips to its entire fleet of 767s currently in service. Steve Holmes, a director at TGM who joined shortly after its formation in 1998, says, “We see a bright future for the aerospace sector despite the downturn over the past 18 months. Having the large-capacity [Hurco] DCX allows us the opportunity to pitch for a lot of new business up to 3.2 meters by 2.1 meters that we could not have undertaken previously.” Optimism has translated into significant investment recently at the Preston facility, which has doubled in size to 16,000 sq ft. A new factory unit houses the DCX32, which has a twin-column, bridge-type construction that allows the large Y-axis travel without loss of rigidity. A 60 kW spindle mounted in a vertical ram gives ample cutting power and torque for machining titanium. A 40-station, swing-arm toolchanger keeps the carousel clear of swarf and maximizes the work envelope. Before TGM purchased the DCX32, their largest machine was a Hurco VMX84 vertical machining center, which was installed in October 2009, and has travels of 84 x 34 x 30 inches. A total of 10 Hurco machining centers now constitute a majority of TGM’s machining capacity.Holmes says TGM chose Hurco when they decided to expand into large size machining centers because they have experienced a decade of prompt service and reliable production using smaller Hurco equipment. In particular, Holmes cites the proprietary, integrated Hurco control system that runs the latest WinMax® Windows®-based software. The control has a 40GB hard-drive with 2GB RAM and high-speed contouring capability. Approximately 40% of the programs, even complex 2D jobs, are written quickly and easily on the shop floor at TGM’s Preston facility using the control’s conversational programming. The time savings allows TGM to respond promptly to urgent jobs, particularly AOG (aircraft on ground) requests. The remaining 60% of programs are prepared off-line using MasterCam. Whether the customer provides a digital file or a drawing of an older component, a 3D IGES file or a 2D DXF file can be prepared quickly and downloaded directly to the control on any of the Hurco machines for immediate use.
