High straightness shaft Bar

Straightness of the shaft greatly affects product characteristics.  ASK is focused on developing technology to ensure high straightness through continuous research and development.  

Case Example: Runout 0.01 mm or less against span 300 mm

Internal Stress Release

After the cold drawn process, the internal stress remains in the steel.   Quality of the finished parts after the turning or heat-treatment is negatively affected by this internal stress.

ASK has established a cold working technology to reduce internal stresses, and has received a high reputation from customers.
