flanged ball bearing

Show cross spiral line traces the emergence of such traces is mainly due to the bus straight wheel of existence, bump phenomenon, Double Row Ball Slewing Bearing‍ when in grinding, the grinding wheel and the workpiece is only part of the contact, when the workpiece or the grinding wheel reciprocating motion after several times, cross spiral line and the naked eye reproduced on the workpiece performance will be observed. The helix pitch and workpiece speed, rotational speed of workpiece size, but also with the wheel axis and the guide rail is not parallel to the working table.

(a) the main reason for the formation of the spiral line

1 grinding wheel dressing is bad, not chamfered corner, without the use of cooling liquid dressing;

Track 2 table guide Other bearing‍ lubrication oil too much, cause the work station floating;

3 machine tool accuracy is not good;

4 the grinding pressure and flanged ball bearing.

(two) with the formation of the spiral line

1.V guide not good rigidity, the grinding wheel edge offset, just contact with the work surface;

2 dressing noisy round table reversing speed is not stable, the precision is not high, the grinding wheel is a slightly less edge trimming;

The 3 workpiece itself poor rigidity;

4 wheel is broken too peeled off the sand and grinding of iron deposition in the grinding wheel on the surface, this should be trimmed worm gear speed reducer‍ grinding wheel with cooling water rinse or wash clean;

5 wheel dressing is not good, local projection etc..
