TRM-120 / TRM‐130B
- Facility overview
- This is a machine that expands the inner and outer diameters or rolls the shape of cylindrical products by cold rolling by mandrel and forming roll.
- Rolling quality
- Metal flow is formed according to plastic working, so there is little heat treatment deformation, so dimensions are stable and wear resistance is greatly improved.
- Cost reduction
- Material yield is improved by 20-30% for bearings.
- The life of the tool is long due to low cost, shortened C/T, and cold plastic working.
- Cold rolling range
- The product is rolled by about 20% of the outer diameter.
- Dimension control
- It is controlled by setting the range in multiple steps in the NC controller.
- Depending on the situation, sizing is attached to control the final dimension.
