Tech Tip: Down Pressures for Low-Profile CNC PadHead

low profile CNC padhead down pressure tech tipWe asked Wayne what’s the optimal down pressures, to start with, when running the low-profile CNC Padhead. Of course this varies, depending on the hardness of the stone and the grit.

Start with a 50% or a 1″ compression when running the lower grits. Each spring is 100 lbs, so 3 springs total 300 lbs of down-pressure for full compression. A 50% compression would then require 150lbs of down-pressure. (.5 x 300)

As noted, do not exceed 600rpms for grits 50-400.

 

 

For polishing with higher grits, 800-8500, you’ll want more compression. Try 75% or 1.5″ compression. By the same calculations above, you would want 225lbs of down-pressure. (.75 x 300)low profile cnc padhead down pressures
