Material is QT600

Positive effect

According to the processing technology of EPC Castings, the castings after rectification shall meet the technical standard required by the rough embryo drawing.

Operation process

Check the equipment, special tools, etc., make full preparations.

Eliminate iron beans burrs on the inner outer surface of the casting.

According to the complexity efficiency of castings, we can choose the heat effect positive cold effect positive according to the sand feeding of EPC casting, we need professional efficiency positive work clothes.

Self inspection shall be carried out for the castings after effective rectification, the qualified products waste materials shall be classified stored. The castings with large effective rectification amount shall be annealed to remove the in-situ stress.

At the end of the work, sort out the calibration tools, remove the machinery equipment, clean the working environment.

The common problems shall damage the casting.

Small belt grinding machine

The processing technology requires that the surface of the casting shall be smooth after grinding.

Operation process

Check whether the operation of the equipment is normal, whether the emery cloth is removed replaced, whether the safety protection is intact.

The operator stands in front of the belt sander, carries out grinding of the casting by hand, puts the ground casting into the box.

At the end of work, remove the machinery, equipment places.
