If higher dimensional tolerances or surface roughness is requested by customer, it needs to rely on machining to overcome.
- To fix the casting on a rotating spindle with the tool made out of round shape which is the main casting.
- The casting is fixed with the tool on the platform with the rotation of the cutting force. The generally 4 or 5-axis can be made into any shape processed products.
- If the surface roughness or dimensional tolerances require more accurate or high hardness can’t be used CNC machining milling. The choice of grinding can be overcame and achieved 1um.
