TOPPER TMV-850A Vertical Machining Center

1. Big diameter pre-loaded ball screw prohibits heat extension. Coupling of servo motor and ballscrew conserves machine rigidity.


2. Coolant through spindle eases deep hole drilling process and chip flow.


3. High transmission spindle motor power timing belt reduces the motor thermal conductivity to the spindle to prevent the expansion of the spindle.


4. The stud pull force is 1000kg. The stud release force is only 250kg. This design could lengthen the lifespan of the spindle bearing.


5. Spindle Bearing Protection uses maze type mechanical seal and air-blow to prohibit coolant entry.
