• With years of experience, combining advanced technology and facilities, YCM has successfully developed highly rigid CNC Turning Centers, TC-46M. TC-46M is specially designed for producing large workpieces with high accuracy, suitable for valve and hydraulic components, shipbuilding, automobiles, construction and energy industries. What's more, TC-46M is equipped with C-axis and motorized turret that provides a wide range of complex milling functions.

Perfect Spindle Design

  • Equipped with A2-11 spindle nose and 15" chuck. (18"/21"/24" chick or customized fixture is optional.)
  • The chuck is operated by pedal switch for more safety and user-friendly.
  • The clamping pressure can be adjusted by workpiece shape and materal.
  • Extra large bearing with excellent rigidity for heavy duty cutting capability.

The Extra Large Front Bearing

  • The extra large front bearing internaldiameter is ø180 mm to ensure the heavy duty cutting capability.
  • Max. hole through spindle diameter is ø130 mm.
  • Max. hole through draw bar is ø117 mm.

Big Bore Hole Through Design (opt.)

  • A2-15 spindle of Big bore hole for flexible chuck 15"/18"/21"/24", hole through Spindle ø182 mm ø7.17".

Rigid Structure Design

  • MEEHANITE® casting frame through FEM analysis for one piece torque tube and 45 degree slant bed ensures the best rigidity and eliminates casting distortion.
  • Z-axis design with an extra wide distance o f 620mm between guideways offers the highest rigidity.
  • The box way base of 950mm is suitable for heavy duty machining and powerful chip removal.

Central Lubrication System

  • The slide ways of X/Z-axis and ball screws are lubricated. Built-in alarm will be occurred when the lubrication oil is insufficient.

Automatic Tool Pre-setter Reduces Setup Time (Opt.)

  • Optional automatic tool pre-setter reduces setup time by minimizing skim cuts and entering tool offsets.

The Smoothest X-axis Movement and Prevents Turret Drop

  • The hydraulic balance cylinder on X-axis ensures the smoothest axial movement and brake system prevents the turret from dropping when the power is suddenly off.
  • With the double nuts design, the ball screws on the X/Z-axis provide the highest rigidity.
  • The optional safety clutch will disassemble the ball screw from motor to protect the ball screw during a crash.

Efficient Chip Disposal System

  • With slanted design and superb chip removal space under the spindle, it is more easiler to clean chips.
  • High pressure coolant is supplied for optimal chip removal.
  • Shower coolant from the roof removes the chips from the chuck and telescopic guideway cover. (opt.)
