 "I don't know of any other machine where you can pull down the file and a half-hour later have a form. You can be mediocre in math, mediocre in geometry, and make a good product in no time."
-Jon Heckman, Tool Room Supervisor, DePuy Orthopaedics
With 31 years of experience in the tool room at DePuy Orthopaedics, Jon Heckman knows machining. As the tool room supervisor for the past 15 years, he knows the importance of efficiency and how to run a lean operation.
DePuy Orthopaedics, based in Warsaw, Indiana, is a leader in the orthopaedic medical device industry. Because DePuy designs and manufactures orthopaedic implants that end up inside patients, the implants can't be touched during the manufacturing process—that's where Jon Heckman's group comes in. Fixturing has to replicate the product, which means the tolerances are tight and the prints don't exist, Jon explains. Whether it's a knee or hip implant, Jon's team of 12 must figure out the best way to transport the implants from point A to point B during the manufacturing process and machine the fixtures that protect the implants from being touched during transport.
Hurco Advantage
"We're a cost efficiency center," says Jon. "People don't want to put money into fixtures. It's imperative that we be effective from the top down." For maximum efficiency, Jon relies on the Hurco VMX line of machining centers. More specifically, Jon says he is impressed with the control's shop floor programming (called Hurco conversational). The Hurco control enables his expert machinists to get their job done faster due to its user-friendly design and intuitive software. "I can't say enough great things about the Hurco," says Jon. "I don't know any other machine where you can pull down the file and a half-hour later have a form. You can be mediocre in math, mediocre in geometry, and make a good product in no time."
Jon says the controls on the Hurco VMX24 and VMX30 machines make the most out of any machinist and eliminate the bottlenecks and expense of investing in CAD/CAM seats. "The Hurco is simplistic to the point that it makes anybody productive—anybody. And that's rare…it's rare to have a machine tool that is that user friendly," says Jon. His group uses the lines and arcs part of the programming software often and appreciates the AutoCalculation feature that eliminates time-consuming data entry and the hassle of trigging out the part.
Although his group mainly cuts plastic and brass, Jon's first experience with Hurco was cutting 17-4 stainless. "One thing that impressed me about the Hurco early on is the way they are built. They are built beefy," says Jon. Another group in DePuy that relies on Hurco machining centers is Prototyping Services. Led by Bill Sellers, this team of eight people meets the challenge of taking the part from rapid prototyping and figuring out the best way to manufacture it. "We're like a job shop within these walls. Our goal is manufacturability of the part," says Bill.
Summary
"In here it’s especially critical that we are able to get up to speed quickly. We don't always have prints, we run one shift, and have about 800 projects a year," explains Bill. With his group, the Rigid Tapping and DXF transfer on their Hurco VMX24 and VMX30 machines are especially popular. At DePuy, employees are motivated to do their best because their work helps restore people’s joy of motion. At Hurco, we are proud to play a part in the process of this life-changing work.
