CNC Lathe - Hurco TM18i Heavy Duty

​​​​​​​​​​​​​​​​​Large CNC Lathes for Heavy Duty Cycles

Our heavy-duty slant-bed CNC lathes are a prime example of customer-centric design. Hurco customers who are suppliers for the aerospace and energy sectors requested larger CNC lathes with high torque capabilities and equipped with the Hurco CNC control.​​

CNC Lathe Heavy Duty Overview

Rigidity is absolutely critical for CNC turning heavy parts—that’s why we evaluate each design decision to ensure it promotes rigidity, reliability, and longevity.                             

  • Design + Construction: It starts with a certified Meehanite® casting, which provides superb dampening characteristics that inhibit thermal deformation and twisting. This robust machine tool features oversized Z-axis guide rails that are strategically spaced to provide excellent support to the cross slide. A wide saddle increases rigidity even further. Ultimately, all of these design features mean the Hurco heavy duty CNC lathes can withstand heavier loads.
  • Maximum Torque The TM heavy duty CNC turning centers are equipped with a two-speed gearbox that gives you the ability to achieve maximum torque at low speeds and maintain adequate torque at high speeds.
  • Servo Tool Turret: Fast turret with 12-tool stations is designed to provide faster and more accurate tool indexes. You can use any combination of ID and OD tool holders.
  • Heat Isolation System: Since heat is the enemy of machine tools, we’ve isolated heat-producing components and added a spindle chiller to promote thermal stability and minimize heat dissipation.
  • Machining Capacity: The generous turning diameter and turning length allow a wide range of large and long part sizes.

Premium Components + Expert Design

  • Spindle designed for maximum torque: The spindle features a cartridge design packed with lifetime grease, which provides maintenance-free lubrication. To maximize torque, the spindle is equipped with a gearbox that switches gears automatically to provide the best torque available at a given speed.
  • Guideways: The guide mechanism for the axes is fitted with precision linear ball rails and box ways for the tailstock. Our linear rails are built with the same precision grinding technology used in the manufacture of bearings because this technology provides superior acceleration and deceleration performance at full load-carrying capacity in all directions. Using Finite Element Analysis (FEA) technology, the size and spacing of the linear ball rails have been carefully matched to the machine’s static (precision boring) and dynamic (cutting and traversing) operating requirements. Each bearing block is independently and automatically lubricated to promote a long life.
  • Ball Screws: For feed drive elements, Hurco only uses premium, quality designed, pre-tensioned ball screws. With up to 98% efficiency, the re-circulating ball nut ensures low friction power transmission from the screw to the slide. This guarantees the combination of high accuracy, high rapid traverse rates, and high feed thrust. Large diameter X-axis and Z-axis double nut ball screws are hardened and ground, centered between the guideways and anchored at both ends with pre-loaded ABEC-7 precision class angular contact thrust bearings. This combination prevents backlash and provides outstanding positioning repeatability with virtually no thermal growth.
  • Axis Drives: To maintain a leading edge in motion control technology all ball screws are driven by Yaskawa or Rexroth servo systems with closed-loop adaptive tuning and high-resolution feedback to obtain the utmost in system performance and reliability. The AC servo motors are direct-coupled to the ball screws for the highest level of accuracy. The brushless AC servo drive motors provide high torque to inertia ratio for the axis drives. The X and Z axis motors deliver impressive torque for peak thrust during heavy cuts.
