The latest One-Lok clamping system from Chick Workholding is available in two sizes – 400mm or 500mm long, offering maximum gripping lengths of 180mm and 280mm respectively. The company says further improvements include a lowering of the clamp profile from 150mm to 134mm, which allows longer spindle travel in the z-axis and also reduces the unit's weight for easier handling.
The mechanism features a squeeze clamping action, which, it’s claimed, applies an equal and opposite force to both jaws and offers 20-micron repeatability. The company points out that on closure, the jaws impart a pull-down action to the workpiece for added security and precision, and the enclosed design reduces swarf accumulation.
