2.chips or small blocks adhered
on blade
1.replace with a soft blade
2.add soluble cutting coolant
incooling water
Come with equal
space of screwlike
trace
1. hit the edge of grinding wheel
2.undesireable regulation of guide
plate
3.high dressing speed
4.diamond tool worn & torn
5.diamond tool holder loose
1.form the edge as cone shape of
grinding wheel
2.make guide plate pareallel
3.reduce dressing speed and
feeding volume
4.change contact surface of
diamond tool
Equal or unequal
space of thin line
1.poor dressing
2.external vibration
1. dressing from edge of
grindingwheel, keep fixed
dressing speed
2.isolation of vibration
