(Renishaw: Hoffman Estates, IL) -- The QC20-W ballbar is an all-new design featuring a Renishaw-developed linear sensor and Bluetooth wireless technology. This provides  greater ease of use and enhanced durability, and allows for testing even in “closed door” manufacturing, where access for wiring can raise safety and procedural issues. The new design also allows testing in three orthogonal planes through a single reference point. A single, simple hardware set up means quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy. The QC20-W ballbar retains the principle of a simple CNC circular program and powerful software. Together, these can quickly diagnose and quantify machine positioning errors, including servo mismatch, stick-slip errors, backlash, repeatability, scale mismatch, and machine geometry, as well as giving an overall circularity error value. Heavily revised system software provides even greater options and  flexibility for testing and reporting. The QC20-W kit is supplied in a redesigned, robust system case, which includes spaces for the most popular accessories.
