Overarm Separator Tooling

Overarm Separator Tooling, Separator Discs- The discs are subject to heavy wear & impact, hence the raw material should be wear & shock resistant. Also they should not be so hard that they damage coils edges. A right combination of material grade & hardness is therefore very important. Most common grades are CrV Alloy Steel, 100Cr6, SAE4340/EN24, 1.2379/D2. The separator discs can be supplied with TiN coating or chrome plating to improve their wear resistance. Generally hardness of 52/56 HRc works well. Separator Spacers- These are generally made from alloy steels. To reduce weight, these spacers can also be made from Polyamide. Rubber bonded steel spacers are made for soft & surface sensitive coils.
