In the past 2 years we have sent engineers to Siemens (Germany), Mitsubishi EDM (Germany), MAG (USA), MAG (Germany), Yushine (Taiwan), Flow Waterjet (Germany), Leadwell (Taiwan), Sanco (Taiwan) , Nikon (France) , Partmaker (UK)  and Renishaw (UK). We pride our selves in excellence through service, and believe in the philosophy of having the correct training for our service engineers.

Renishaw XL-80 laser measurement system

The XL-80 laser interferometer offers the ultimate in highperformance measurement and calibration for motion systems, including CMMs and machine tools. Linear measurement accuracy is an assured ±0.5ppm over the whole environmental range. Readings are taken at 50kHz, with a maximum linear measurement speed of 4 m/s and a linear resolution of 1 nm. 

QC20-W ballbar

The QC20-W is a completely new design featuring a Renishaw developed linear sensor and Bluetooth wireless technology. This design offers benefits in ease of use and enhanced durability, and allows the QC20-W to be used for testing even in “closed door” manufacturing, where access for wiring can raise safety  and procedural issues.
