MultiMachine, an open-source machine tool
The spindle can be as simple as a piece of pipe machined to fit the inner diameter of the bearings. The fourth "secret" is the addition of a third bearing to the spindle. The three-bearing spindle is necessary because the "main" spindle bearings just "float" in the cylinder bore so that the third
Hard Turning and Grinding on a Single Machine | Production ...
The working speed for turning is noticeably higher than that for most grinding operations. If the machine is also to be used for soft turning, the maximum main spindle torque will experience more demand than that of grinding. An important requirement is a good chip clearance. Grinding makes its own demands on the grinding spindles.
