The Chick One-Lok CNC vice system has a maximum capacity of up to 432 mm, incorporates Chick's 'Boltfast' interchangeable jaw system and provides locational repeatability of 0.02 mm.
Machining accuracy is enhanced by the unit's 'squeeze' clamping configuration, which applies an equal and opposite internal force to the fixed jaw as the moving jaw closes, providing virtually deflection-free component clamping with a maximum retaining force of 10,000 lbf.
The vice also imparts a pull-down action to the workpiece for increased security and precision.
One-Lok features a 'QwikSlide' mechanism that allows the moveable jaw to be easily unlocked and slid forwards or backwards to achieve rapid set-ups.
A further feature of the unit's compact, modular design is its hardened, precision-ground cast iron base, which not only provides a solid working surface, but also eliminates swarf traps, reducing the need for fixture cleaning between machining cycles.
Available as a stand-alone workholding system, complete with a set of hard jaws, toe clamps, operating handle and jaw-change T-wrench, the One-Lok is complemented by an extensive range of machining accessories, including: stepped hard jaws, outboard mounted hard jaws, soft jaws, an adjustable workstop, foundation stops and locating keys. In addition, purpose-designed spacers enable existing knee mill vice jaws to be quickly installed to the One-Lok base unit without modification.
