[0003] In mechanical processing, the workpieces are generally made of metal materials such as cast steel, cast iron, and cast copper, and are processed by clamping and positioning the claws on the chuck. For flanges and gaskets made of soft non-metal materials such as rubber and nylon, they were previously made by scribing, manual shearing, manual knife cutting, and grinding wheel cutting. Not only are the labor intensity high, the efficiency is low, and the drawing size cannot be guaranteed, there are also certain safety risks, which cannot meet production needs.

[0004] The double-column vertical lathe has two vertical tool holders connected to the crossbeam. It has a large processing diameter and a high height. The vertical tool holder in the single-column vertical lathe can also be adjusted up and down. Therefore, different processing requirements can be achieved by changing the relative position of the tool holder.

[0005] Therefore, the utility model designs a new type of vertical lathe tool holder for processing non-metallic flanges, which can realize the processing of large non-metallic soft material flanges, gaskets and other workpieces such as rubber and nylon, and can even realize the processing of non-metallic workpieces with complex structures and a certain height (such as large non-metallic sealing flange labyrinth sealing grooves).
