Apr 23, 2012· If you aren't concerned about height and just want to use them to mill parts in your vise, all that matters is that both parallels are the same height and that can be accomplished by grinding both at the same time, or match grinding them. Because of these tolerances, a decent set of parallels requires the use of a surface grinder unless you ...
The roll is out of concentricity tolerance. The correct way to measure concentricity on a grinding machine is 180º from wheel (back side), if the roll is supported on grinding seats. For example, if the grinding seat is out of round this form will be transferred to the roll shell by the grinding wheel.

The point angle is governed by the final wall thickness. Sharp points of 90 to 110 degrees are best for heavy walls and large diameters, while blunt angles of 115 to 130 degrees are better for thin walls. Close tolerances call for feed ranges of to ipr. Feed rate of ipr can be used where tolerances .
