The use of ball bearings and tool holders for the cutting of slender workpieces or soft materials (such as plastic bars) can achieve good processing results. This tool holder is very simple to make. The ball bearing and the tool holder are formed by an aluminum plate milling saw. As shown in the figure, the horizontal span of the body frame is installed in the seat 6 of the lathe composite tool holder, and the lap under the body frame has a certain length and is driven by the lathe pallet, so that all the driving can be avoided.
