SMW BP Chuck Made for Harsh Machining Environments

SMW Autoblok’s BP chuck is a standard, fully sealed power chuck designed with large a through-hole for maximum precision and durability. The company says the chuck is well suited for CNC lathe applications thanks to a large through-hole that enables flexibility for virtually any application where a standard chuck is used, including OD and ID clamping, bar stock clamping and shaft clamping. Users can also convert the BP to a collet chuck using collet pads for small diameter parts.

The BP is said to maintain high productivity even in harsh environments, including dry machining, abrasive powders, high pressure or corrosive coolants and more. Constant grease lubrication provides clamping force consistency and reduced wear to greatly reduce downtime and loss of productivity, the company says. The BP also eliminates daily maintenance intervals, only requiring maintenance checks every 2,000 hours.

The chuck is fully Proofline-sealed from outside contaminants, enabling the BP to maintain a consistent grip force for repeatability at high speed, versus non-sealed chucks which can lose more than 50% grip force if not maintained properly. Other advantages include a case-hardened body and internal parts for high resistance and longer life.

Available in 210, 260, and 320 mm, BP series chucks accept all industry top jaws. The BP-D utilizes master jaws with inch serration, while the BP-M operates with metric serration (suitable for Japanese jaws). The American standard tongue and groove master jaws, are available on the BP-C.
