Chick One-Lok

10th December 2009: The Chick One-Lok CNC vice system is the latest evolution of workholding technology to be added to 1st Machine Tool Accessories’ (1st MTA’s) portfolio of high productivity machining equipment. Developed from scratch to meet the speed, precision and flexibility demanded by modern CNC machining operations, One-Lok eliminates the shortcomings of standard knee mill vices based on 1950’s technology. With a maximum grip of up to 17 in (432 mm), One-Lok incorporates Chick’s new ‘Boltfast’ interchangeable jaw system, which enables soft or hard jaws to be replaced with a single turn of a locking screw, to provide locational repeatability of 0.0008 in (0.02 mm). Machining accuracy is further enhanced by the unit’s novel ‘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. In operation, the vice also imparts a pull down action to the workpiece for increased security and precision. Unlike traditional machining vices, which require up to 70 complete revolutions of their operating handle to be fully opened or closed, 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.
