Commercial Cam Grinding Machines are adaptations of cylinderical grinding machines. The shafts they form are usually induction hardened before grinding, so distortion ooccurs and cylinderical grinding of the journals is required to being them into line. The schematic here shows a commom pattern employed on many commercial cam grinders.

As all circuits will drift with time, the DMM will need to be periodically re-calibrated to ensure that it is operating within its specification. The calibration period will form part of the specification for the DMM. The most usual calibration period is a year, but some digital multimeter specifications may state a 90 day calibration period ...
Jun 15, 2012· Backlapping should never be a substitute for grinding. There will come a point in time during the reel's life where simply backlapping alone will not be sufficient. The land area of the reel blade will eventually increase, the length of the relief angle will decline, and there won't be as much surface area to hold the backlapping compound.
Grinding or not to grind depends on if it is code work or not and what the code and welding engineer specifies. First let's remember that stress travels on the surface and the more stress you have the deeper it goes, requiring thicker material. So...
