Main used for marbe and granite cutting.
Cut it is semi products without diamond segments.
General size is 300mm diameter to 2500mm diameter (or larger if needed).
The main materail is 75Cr1, some factory use 50Mn2V/65Mn, but I think 75Cr1 is better.
Generally the slot is U style and key style for small size around 300mm-500mm.
The technical tension demand, side runout, radial runout, balance, tolence ect details affect final cutting result.
