Turning Hardened Steel roll with Halnn BN-S20 CBN inserts
The mill roll is the main consumable part of the rolling machine, which has high hardness, and is casting workpiece. Especially the large mill roll surface with sand, porosity and other casting defects caused the insert often collapse in turning process, even affected seriously surface quality, which brings large difficulty to process mill roll.
The advantages of processing hardened steel roll with BN-S20 cbn inserts
(1) Roughing forged steel with large margin cutting
(2) Strong impact toughness, it doesn't collapse when encountered uneven mill roll surface
(3) Multi-edge, cost-effective
(4) Instead of roughing grinding process
Application industry
Engineering machinery, transportation industry, mining machinery, metallurgical machinery, energy sector, such as high speed steel rolls, forged steel cold roll, large gears, high manganese steel, rolling hard steel, heat-resistant alloys, thermal spraying and other hard surface spray processing field.
