Hello,

can someone please give quick approximations for lathe chuck forces:

*typical Chinese 4-5" chuck nondestructive maximum clamping force

*typical Bison 4-5" chuck nondestructive maximum clamping force

*reasonable clamping force for holding stock 1" diameter, 6" length, 6062 aluminium at 1000rpm for light cuts.

*reasonable clamping force for holding stock 1" diameter, 6" length, 300 series austenitic stainless steel alloy at 1000rpm for light cuts.

Just so I can get some idea of the forces involved. Higher end chucks have maximum clamping forces rated but I have yet to find info on low end chuck.

Thank you!
