Precautions／Service Network Notes on Air Supply CNC Circular Table comes standard equipped with an air purge outlet. (Use it to blow out condensation and coolant to prolong the life of electrical parts and prevent rust in the motor housing.) Supply clean air for the air purge by referring to the drawing shown below. Pressure setting: 0.02 MPa Air consumption: 15L/min CNC Circular Table uses an oil bath to protect the internal mechanisms and maintain reliability. Refill and perform oil changes regularly using the oil listed in the instruction manual. Grinding Machine Applications ■When used...
