[0002] There is no specific machine tool for tungsten internal thread processing on the market. The processing methods used by companies producing tungsten internal threads are basically based on the internal thread processing methods of steel parts, such as manual tapping, tapping machine tapping, and machine tool milling. At present, the thread milling cutter of the existing ordinary milling machine cannot adjust the size of the workpiece in the diameter direction, and cannot meet the needs of adjusting the size in the diameter direction when milling. It is very inconvenient to use, and the cost of CNC milling machines is high, which increases the production cost of enterprises.

[0003] In view of the above reasons, a milling cutter tool for a rigid-flexible machine tool for internal thread processing of tungsten material is developed. Utility Model Content

[0006] Furthermore, the shell is cylindrical, a circular cavity is arranged at the lower end of the shell, a ring-shaped cavity is arranged at the upper end of the shell, the ring-shaped cavity is communicated with the circular cavity, rectangular mounting grooves are arranged on both sides of the shell, an observation groove is arranged on the front side of the shell, and a ruler is arranged on the side of the slide rail corresponding to the observation groove.

[0007] Furthermore, the scale includes a main scale arranged on the slide rail and a cursor arranged on the slider. The cursor is connected to the slider via a pair of connecting rods. The pair of connecting rods are respectively located on the left and right sides of the pneumatic rotor.

[0008] The beneficial effects of the utility model are as follows: the tool is driven to move left and right by the telescopic cylinder to complete the size adjustment of the diameter direction of the workpiece; when the tool is processed to the set depth, the tool is automatically retracted to the center position by the cylinder control; the moving length of the tool is controlled by adjusting the offset adjusting bolt; the scale adopts the reading method of the vernier caliper to clearly see the moving length of the tool, and the size adjustment of the diameter direction of the workpiece can be achieved on an ordinary milling machine, which greatly reduces the production cost; the utility model has a simple structure, ingenious design, low manufacturing cost and good use effect; the parts not described in detail in the utility model are existing common technologies.
