    Enco (Rong Fu RF30) Mill/Drill Conversion

    That did the trick Chuck. I bought some nice new 2 flute hi-helix cutters. I managed to pocket a 52mm Dia hole 15mm deep at 400mm(15 inches) per minute at 1mm pass depth with no issues at all. I used parafin misting as a coolant. Thanks for your help. George

I copied your setup with a 15 Tooth Pulley and a 36 Tooth Pulley. 2.4:1 I also confirmed that it takes 10 turns of the crank for 1"...

    Enco (Rong Fu RF30) Mill/Drill Conversion

    Thanks Chuck, I value your input. My reason to go to the Ballscrew Z axis is that I have lost major steps with the arrangement like yours. I broke a couple of cutters and that was on aluminium where the axis lost it's place and drove down through the material!!!! My set cut depth was only...
