Description
Chucks are designed for clamping workpieces machined on lathes of “B” accuracy class in producing multiple units.
A motorized drive mounted on a back spindle terminus of a machine starts a chuck.
Adjustment of a required clamping diameter is performed by remounting of hardened top jaws to base jaws riffling, in this case required chuck accuracy remains. A chuck is available with grease lubricators for lubricating working surfaces of a chuck. The advantage of a chuck is that it has a through-hole which allows machining workpieces by passing them through the machine spindle. Chucks are interchangeable with the chucks produced by leading European manufacturers (SMW-AutoBlok, Schunk, etc ) and Asian manufacturers (KITAGAWA, AUTO Strong, etc.).
Standard equipment:
Ordering example: a power hollow chuck, outer diameter 210 мм, through-hole 52 mm with adapting flange (mounting type A6) and jaws serration pitch 1/16’’х 90°: PPM-210.52D/А6.
A set of hardened jaws is available at an additional cost.
