A new type of tool holder

The method of clamping the tool by the tool holder is to clamp the tool by pulling force (see figure). The tool loading and unloading is very convenient and can improve the efficiency, and the effect is better on the lathe (vertical car, sleeper) and the inserting bed. The size of the tool holder 4 can be determined according to the size of the workpiece and the selected tool. In use, the tool is loaded into the square mouth of the tie rod 3, and the nut 1 is tightened to clamp the tool for use. It has been proved by practice that the new arbor is easy to use and reliable.
