EV driving motors are required to have output characteristics that can exhibit performance over an entire range from low-speed to high-speed rotation, and the development of lightweight shafts with excellent dynamic balance have been developed in recent years.
Shafts are becoming hollow to reduce their weight, and it is becoming necessary to handle deep hole drilling in recent shaft operations.
Automobile shafts are made of low carbon steel, which has many chip control problems in production.
Machining process after hardening is also required in shafts, so how to achieve highly efficient and economical use of CBN inserts is also an important factor.
Tungaloy‘s unique technology provides comprehensive solutions for deep hole drilling, improving chip control and efficient use of CBN inserts.
