CNC Lathe – General Purpose
The Hurco TM8i CNC slant-bed turning center is equipped with a small footprint, large work cube, ergonomic design, and an affordable price tag. 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, providing a more rigid turning center than competitive models in its class. The generous turning diameter and turning length allows for a wide range of part sizes and applications. All of these features and design structure of the Hurco CNC slant-bed turning centers make small batch manufacturing profitable.
The small footprint, large work cube, chip management system, and affordable price tag of our slant-bed CNC lathes in the TM Series make small batch manufacturing profitable. The TM turning centers are designed for general purpose turning applications and provide an easy transition from manual turning or milling.
At the heart of the TM slant-bed lathes is the power and flexibility of the integrated Hurco control powered by WinMax®. The 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. No other control offers the level of flexibility that you will experience with the Hurco control. 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.
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.
Spindle Motor and Drive: The spindles on the Hurco TM Series of slant-bed CNC lathes utilize poly-V belts, which are ideal for turning. The spindle speed ranges have been engineered for the best metal removal rate for a given chuck size, up to 6,000 rpm. We use precision steel bearings packed with lifetime grease, which results in a maintenance-free lubrication. The brushless, AC motor drives the spindle and delivers impressive power and torque.
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.
