Note: this drive system diagram, just roughly indicates the installation position of the
components. In the bearing distribution table, will be "close to the motor side", "far away
from the motor side" to explain the text.
Table 5-1 important bearing distribution table
Note: bearing models refer to the country's latest standards.
5.2.1 Main drive system
The machine main motor direct drive spindle motor, spindle box has cancelled the gear
transmission mechanism, simple structure, easy maintenance, high reliability. Transmission
through the main motor by DC brushless motor, DC stepless speed regulation. Spindle positive
inversion through the electrical system control, positive inversion has the same speed.
5.2.2 Work piece clamping mechanism
The configuration of the machine tool work piece clamping mechanism is three jaw chuck
and the power source is manual .
Warning :
All tooling and work piece clamping mechanism installed on the spindle must consider its
dynamic balance, otherwise it will greatly damage the spindle bearings, severely punish will cause
the body to scrap or damage the safety of the operator.
