Five Problems That Are Often Neglected for Grinding Machine

The contact conditions that should be paid attention between grinding wheel and workpieces.

When the workpiece surface has a contact with grinding wheel, people can hear hissing sound continuously. The water stains on the surface of workpieces can be taken away by grinding wheel, and at the same time, people can see weak spark. And then it needs to increase the cooling fluid, whose concentration is a little higher than ordinary saponification liquid. But it requires filters cleaning, and then feeding.

The feeding rate is 0.005 mm per double stroke at a time, and it needs to grind until no spark in the end. At that time, the direction of feeding handwheel should be controlled and changed slightly, which is equal to a kind of polishing for workpieces. This can guarantee that the workpiece surface roughness can reach Ra0.02 microns.

To prevent the workpiece inflation

When grinding during the summertime, people need to use machine headlamp that can get close to the workpiece, in order to prevent the lamp heat expansion and affect the quality of grinding workpieces.

Workpiece surface galling

There is galling on the surface of workpieces, which is because the coolant is not clean or there is floating sand on the surface of grinding wheel.

There are local burns on the surface of workpieces.

This is because of insufficient cooling fluid and too large feeding, or it is caused by passivation of grinding wheels.

There are local ripple on the surface of workpieces.

After processing, the workpiece surface is very good for the most part, but there are local micro ripple on the surface of workpieces, which could be caused by main shaft, motor vibration or other causes. People need to take corresponding measures to solve them according to specific situation.
