STM-3225
The mainspindle is made of special steel which also treated by high frequency heat treatment and precision ground. Especially. This machine be installed five sets tools and fine adjusted screw for processing high precision workpiece. As for, the sliding unit is made of high grade cast iron and the sliding surface also be treated by high frequency heat treatment and precision ground.
The unit is adopted magnetic clutch to drive tapping shaft, and the tapping processing is employed the differential speed which generated by high speed rotating in same direction, Especially the two shaft can be swivelled and processing, exchangably reaming, boring deep hole and tapping can be completed simultaneously.
Exterior cutting is employed the plate cam, But the rectangle cutting be used the bell cam and the shaft can be divided into two portion frosm the central journal. Furthermore, the cam can be retained in original condition and exchanged additionally. Since, the total set be assembled & exchanged within short time, Moreover, which can be changed to manual in necessary, high efficiency.
