The KSF-08/RC is a 210 mm diameter chuck with a 66 mm through-hole, while the larger KSF-10/RC is 254 mm diameter with an 82 mm through-bore. Both are rated up to 5,000 rpm and can be specified with A2-5, A2-6 or A2-8 spindle mounting plates.
Featuring a boltless design, the rapid change jaws are supplied soft as standard, with hard jaws available as an option. KSF chucks offer a repeating accuracy of 0.0025 mm, such that when top jaws are finish machined on the chuck, MicroCentric guarantees that parts will run within 2.5 micron radial and lateral TIR, if the top jaws are not removed from the chuck.
