CNC Lathe – General Purpose Mill Turn
The Hurco TMM8i CNC mill turn machine is a true slant-bed lathe equipped with live tooling. These mill turn lathes are the perfect way to make small to medium lot sizes that require turning and secondary milling/drilling operations profitable. The rigid one-piece machine base casting is designed to yield excellent static and dynamic performance in addition to outstanding dampening properties that inhibit thermal deformation and twisting. Save time with one setup and you won’t lose accuracy due to refixturing.
The most significant advantage the Hurco TMM mill turn machines is the simplified programming and operation via the control. Learn more about mill turn control features. Beyond the control technology, the TMM mill turn machines have multiple design features that prove valuable for mill turn applications.
Hurco engineers have made sure the control of the TMM mill turn lathes has features that simplify 3-axis turning. For example, when programming holes on the face of a part, you can choose to program in polar or rectangular coordinates. Additionally, the threading cycle performs multi-pass threading for outside diameter (OD) and inside diameter (ID) threads. The control simplifies threading—you can easily set spring passes, decreasing depths, and multiple starts found in complex threads on one screen.
As with all Hurco machine tools, our integrated control can be programmed on the shop floor with Hurco’s patented conversational programming or industry standard NC. Our control lets you choose the best method of programming for your shop and for each individual job. Additionally, the easy-to-use touch screen provides helpful setup and verification graphics that show cuts on the screen before they are executed—virtually eliminating wasted materials and potential machine crashes.
Additionally, the Hurco mill turn machines have all of the popular productivity features found in TM and TMX lathes.
DXF Transfer: Eliminates the need to hand code complex profiles.
3D Verification Graphics: Half and quarter views with semi-transparency to see more of the toolpath information especially inside the part.
Auto Tool Nose Radius Compensation: Eliminate the need to use trigonometry to compensate for the tool nose radius on start and end positions of a toolpath.
Conversational Programming: Our founder invented this intuitive, straightforward programming method that leverages the power of technology to do what software does best—the redundant and mathematical tasks—and leaves the machining expertise to you. Features such as AutoCalc, Constant Surface Speed, and Diameter or Radius Programming, are just a few examples of how conversational simplifies complex processes.
ISNC (G Code) Programming: While we’re known for our conversational programming, the NC side of our control accepts FANUC formatted programs, including macros, and is compatible with the most utilized CAM systems.
At Hurco, mill turn machines are built for increased rigidity with an extra wide saddle and large Z-axis rails. You can be assured our TMM mill turn machines have the premium components and rigidity you need.
The VDI servo turret provides quick change tooling and fast indexing, features large, curvic coupling for superior rigidity, and makes all stations live-tool capable.
The short, live-tool drive train generates less heat, and provides more torque transfer to the tool, higher reliability, and quieter operation.
Advanced spindle technology with high output spindle motor. Additionally, the spindle motor is strategically designed for easy access and easy maintenance
Guide ways: The guide mechanism for the axes is fitted with precision linear ball rails. 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 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 guide ways, 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.
Our control technology is the greatest advantage of our lathes because the technology we develop yields the greatest opportunity for our customers to increase profitability via increased productivity. With large capacity memory, a fast processor, and multiple control features that minimize setup time, you will benefit from a control that helps you get from print to part faster.
