My Harbor Freight Vertical Knee Mill (40939) Review
I measured ZERO backlash on the spindle up/down movement and ZERO on the table in/out. It's got a monster motor. Spindle up/down is 10tpi. It feels pretty solid. Standard R8 spindle. SO-SOs:.003" backlash on the table left/right movement. It comes with casting sand all over it.

A Comparison of Three Types of Coal Pulverizers
The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
