Product Feature

Traveling Column

The column moves along the X-axis and the table is fixed. Therefore, the workpiece weight does not affect the axis transmission system and dynamic machining accuracy.
Moreover, higher machining efficiency is obtained.

  • Extra Large Y-Axis Travel
    The specially designed extra large Y-axis travel provides increased machining range.
  • Smaller Footprint
    Compared with a double column milling machine under the same cutting conditions, HEAKE'S TVML series has a smaller footprint and higher accuracy.
  • Reinforced Column Structure
    The thickness and Box-in-Box type structure designed of HEAKE'S TVML series have been reinforced to effectively avoid a pull-down force caused by the throat depth when the spindle is performing cutting.
  • Four Block Deployment
    Each linear guideway on the y-axis is equipped with four blocks (total of 8 blocks) to enhance rigidity.
  • Cooling Through Ball Screws (Oil / Air)
    With the use of cooling through the X, Y, Z-axis, the thermal expansion of the ball screws is reduced to a minimum, therefore ensuring high machining accuracy and stability of axial movement. (NEW type patent no, M.502117 in R.O.C)

Ball Screw Support on X-Axis for 3M～4M Travel

  • X-axis feed is transmitted through the ball screw with support which eliminates the overhang problem for outstanding transmission efficiency.
  • X-axis is equipped with linear scales (standard accessories), ensuring high positioning and repeatability accuracy.

Rack Transmission on X-Axis for 4M～7M Travel

  • X-Axis power is transmitting through the German racks, which feature outstanding transmission efficiency of axis feed. Additionally, X axis is equipped with linear scales (standard accessories), which ensures positioning and repeatability accuracy is not affected by thermal expansion.

Roller Type Linear Ways on Three Axes

X, Y, Z-axis are fitted with SP class roller type linear guideways with outstanding features, such as high load resistance, high-rigidity, low friction co-efficient and excellent dampening capacity.

Linear Guideway Slide Block Cooling System

Independent Air Accumulator

Choice of CNC Controllers

Heake offers two types of CNC Controller for customers to select, including 5-axis controller and 4+1 axis controller.

Roller Cam Drive Features on B-Axis

  • Zero Backlash
    Roller contact between the roller and the cam eliminates the positive reversal backlash problem, thus greatly improving the ultra-precision characteristics of the cam.
  • Ultra-High Efficiency Conduction
    Roller cam type turret functions in rolling mode, providing ultra-high conduction efficiency of over 90% at high speed operation.
  • No Thermal Displacement
    Roller cam drive dramatically reduces thermal displacement even at high speeds.
  • Equip with a standard optical scale to enhance machining precision.

Built-In Type Spindle

  • The spindle features high precision, high-precision, high-speed, high-rigidity and low vibration.
  • Excellent for high-speed, high-precision machining where a fine surface finish is required.
  • Max. spindle speed: 12,000 rpm (Standard) / 15,000 rpm (Optional)

Direct Drive Rotary Table on C-Axis

  • The rotary table is embedded in the rectangular table.
  • Direct drive features backlash-free tansmission, ensuring outstanding machining accuracy and fine surface finish.
  • Indexing accuracy: 10 sec.
    Repeatability: 4 Sec.
  • Equip with a standard optical scale to enhance machining precision.
