A trouble and measures of the whetstone
The abrasion of the whetstone is early
A state: Oversight
Cause
● Abrasive depth of the cut is big (per nothing drink)
● Bond is soft
● The dilution magnification of the grinding fluid is high
Processing condition
● I lower the forwarding speed
● I raise whetstone number of revolutions
● I lower the depth of the cut
Whetstone
● I raise a particle size
● I give an intensive degree
● I harden bond
Grinding fluid
● I lower dilution magnification (I raise density)
Load gradually grows big, and processing is not continued
A state: Close eyes
Cause
● Abrasive depth of the cut is small
● Bond is hard
● The dilution magnification of the grinding fluid is low
Processing condition
● I give forwarding speed
● I lower whetstone number of revolutions
● I give depth of the cut
Whetstone
● I lower a particle size
● I lower the intensive degree
● I soften bond
Grinding fluid
● I raise dilution magnification (I lower density)
A state: Blocking
Cause
● Grinding fluid does not arrive to a processing thing and the contact point of the whetstone
● Grinding fluid is polluted
● chippupoketo of the whetstone is small
Processing condition
● I lower whetstone number of revolutions
Whetstone
● I change a shape (I put a slit)
● I lower a particle size
● I lower the intensive degree
● I soften bond
Grinding fluid
● I raise supply pressure
● Change
Tipping is easy to be given to the processing thing
Cause
● Abrasive depth of the cut is big
Processing condition
● I lower the forwarding speed
● I raise whetstone number of revolutions
● I lower the depth of the cut
Whetstone
● I raise a particle size
● I give an intensive degree
Grinding fluid
● I lower dilution magnification (I raise density)
