The HPGA (High Precision Generic Arm) is the latest addition to Renishaw`s successful family of high precision tool setting arms, for use on grinding machines and CNC lathes. The HPGA delivers improved multi-axis directional repeatability to meet the ever tighter measurement and performance demands in the market. The arm incorporates Renishaw`s new SwarfStop™ seal design that significantly improves protection against sharp metallic particles in both grinding and normal machining environments. The HPGA supports both the LP2 compact probe and the high accuracy strain gauge probe, MP250. It uses hard-wired connections to the machine control via Renishaw`s TSI 3 and HSI interfaces.
