General Infos

High-rigidity and high-precision mechanical structure

  • Main mechanical structures, such as: base, column, saddle, etc., are made of Meehanite casting iron with the process of heat treatment to release the residual stress to ensure every actual miniature movement and to maintain a long-lasting accuracy.
  • Box-shaped structural design on beam, together with ladder-like layout of linear guideway makes the combining span of saddle wider and assures a powerful and stable machining capability on the spindle.
  •  The design with 3-axis roller-type high-precision linear guide-ways acquires a quick response in acceleration and deceleration and gets the rapid traverse up to 32 m/min.
  •  3-axis ballscrews, being pre-stretched, can effectively refrain from the thermal deformation and surely guarantee the precise positioning accuracy and repeatability accuracy.
High-rigidity and high-precision mechanical structure

No-counterbalance design on headstock

  • The no-counterweight structural design on headstock is without stagnant phenomenon caused by inertia and no vibration resulted from the counterweight, but with the agile, quick and stable response in feed.
  • Z-axis linear guideway with 6 blocks ensures good accuracy in long-term operation and long service hours.
No-counterbalance design on headstock

High-precision and high-performance spindle

  • Embedded automatic thermal compensation appliance  can effectively refrain from the thermal deformation and surely guarantee the accuracy.
  • The cooling system on the spindle makes sure the temperature stability in spindle operation and restrains from the thermal deformation on the spindle to optimize the machining accuracy.
High-precision and high-performance spindle

Chip flushing function and oil-skimmed design

  • The inclined-plane design on the chassis, together with the flushing coolant system on both rear sides, makes chip removed effective.
  • Oil-skimmed design – the water tank with oil skimmer makes the service life of coolant longer.

Automatic Tool change

  • Tool magazine with double gripper 20 seats, 96 seats optional
