The lube system must work very well, as I took one at work, mounted a large 1/2" disc of steel on it, mounted 16 outward facing 200 DA collet setups on it, and motorized it with a DeWalt right angle half inch drill. A speed control is used on it, and it is used to mill a chisel shaped tip on short copper parts at 500 per hour by passing the parts through a set of cutters. The vertical mill has an arbor with a pair of double angle arbor style cutters on it. A pair of Bosch trim routers is used to take a final trim of .005 off each surface to eliminate burrs. This "invention" has been running about once a month for over 10 years with no issues. I was originally concerned about the life of the unit, relative to lubrication and wear. So far, so good.
