[QUOTE="shortgrass, post: 2457802, member: 24284"] CNC mills have 'ball screws'. Takes less power to move the table and they are accurate. CNC knee mills have the capability to be operated manually, but, who would want to?(I know this from my machine shop experience) Most gunsmiths still have and use manual, Bridgeport style vertical milling machines. No real need for CNC unless you are doing repetitive work. Ya', they are nice, but...... In my world, gunsmithing is "one-off". I would not build a power knee lift, I would just buy one. there are numerous makes and models available. One made for the Z axis will have more ft lbs of 'drive' than one designed for the table. I have operated vertical mills with a power Z. All I ever used it for was the rapid traverse feature to raise/lower the table. The CNC vertical mills I have been around and operated had power Z on the quill, not the table. Had DRO on the manual raise/lower so height could be returned or moved to a specific place. [/QUOTE]
