5Tips of Vibration Analysis in Grinding Machines|Newdiatools

Oct 08, 2019· Tips of vibration analysis in grinding machines. When precision dies grinding, it is very difficult to solve the problem of vibration of the grinding machine. Because the vibration of the machine tool directly affects the effect of the dies processing. For example, the surface finish is poor.

ANALYSIS AND CONTROL OF VIBRATION IN GRINDING MACHINES

The reading obtained from without load is 2.8mm/s and the reading obtained from with load is 25 mm/s. Thus the severity of the vibration is reduced by using the damping method. 6. CONCLUSIONS The study reveals that the vibration was measured in grinding machine. This was the one of the major hazards in grinding machines.

ANALYSIS AND CONTROL OF VIBRATION IN GRINDING MACHINES

Vibration in grinding machine is hard to measure. It is witnessed from the formation of waviness on the work piece and grinding wheel. The major causes of vibration in grinding machine

Measuring vibration on precision grinding machines

Self-excited vibration occurs only during grinding, due to grinding parameters, the process, and certain machine characteristics such as natural frequencies of the machine. During grinding, undulations/waves can start to form on either the workpiece or the grinding wheel as fluctuating forces excite a natural frequency on the machine.
