Problems: honing bad repair, processing out of roundness with straightness is beyond 0.005, how can we repair the bars better?
Dressing method:
1) The new mill shall have to stick after a good cylindrical grinder "regulation round," especially diamond grinding bar, if you want to regulate circular grinding tens of thousands of products it may be normal use. Regulation circle is to use the grinding tooling fixture, up from the bars, then grind the bars (average until). General grinding comes with this tooling factory, note first cylindrical grinding can be corrected when the mill. It should be noted that after the regulation round the bars also cannot guarantee that all the average attendance, or to pre-ground so few artifacts to the final amendment.
2) The quality of the work piece fixture will seriously affect roundness and column degrees. Fixture must be corrected, and the spindle concentricity, sureness shall not be greater than 0.02.
3) Column degree also concerned with your school trip should pay attention to adjust.
