1. High-precision centerless grinding machine vertical wheel drive system

The adjustment wheel spindle motor is probed by the Japanese split servo. The speed control is 10~250rpm without the digit setting. It can be adjusted to the optimal full speed. When the outer diameter of the adjustment wheel changes, the same green speed can be maintained. With the transmission of the timing gauge belt, it can reduce vibration and reduce noise. The motor base and the main shaft base are integrally connected, and the motor also follows the trouble when the adjusting wheel is tilted, completely eliminating the problem that the pulley and the belt are not parallel and twisted.

2. High-precision centerless grinding machine spindle circulating oil system

2.1 dynamic pressure type

The main shaft automatic lubrication and oil pressure dressing are suitable for the same oil pump. The external oil tank is convenient for cleaning and oil change. The circulating oil is filtered by two oil filter nets and equipped with a pressure controller to ensure the life of the main shaft.

2.2 static pressure type

The grinding wheel head hydraulic pump and the grinding wheel spindle drive motor are interlocked. When the grinding wheel start switch is pressed, the lubricating oil must be tested by the pressure switch before reaching the bearing. If the pressure is insufficient, the pressure switch cannot be pushed, the spindle motor will not start, so when the pressure When the valve is insufficient or the oil circuit is blocked, the pressure switch automatically stops the spindle operation and protects the spindle and the bearing.

3. Pressure regulating valve

The grinding wheel spindle maintains a high hydrostatic pressure device, and the high pressure oil is used as a radial bearing to support the oil inlet with a pressure regulating valve, and the working pressure is set to 20 Kg/cm2.
