How does the performance of an electric spindle assembly relate to the bearings?

Machine tool bearing accuracy and quality are key factors affecting the performance of machine tool spindles. For how to define the precision level of a precision bearing, only the width tolerance of the inner and outer ring, roundness, verticality, taper, axial runout and radial runout are defined. To make the machine tool spindle can achieve high precision, high speed, high stiffness and low vibration and heat requirements, it is necessary to control more parameters of the bearing itself.

High-speed electric spindle troubleshooting

The system has a corresponding electric spindle signal output, but the power supply line and the control signal output line have a break or the components are damaged. Treatment: Use a multimeter to check if there is a break in the power supply circuit and signal control circuit between the system and the spindle motor.

What are the ways to reduce the failure rate of electric spindles?

The electrospindle is in close contact with the bearing outer ring end face and the threaded section and end face have high perpendicularity requirements and can be checked by contact. If the electric spindle has 80% contact, the end faces can be lapped to meet the perpendicularity requirements. This work is important. Its accuracy affects the radial runout of the grinding spindle and thus the surface roughness of the ground workpiece.

Analysis of forced shutdown situations for electric spindles

Under normal circumstances, electric spindles need to follow the steps to shut down after use, but sometimes there are situations where the spindle has to be forced to shut down. For example, the temperature of the electric spindle bearing has risen sharply and has reached the alarm value, which requires a mandatory shutdown; or the electric spindle bearing or the sealed area is smoking, which requires a mandatory shutdown.
