HPGA high precision generic arm

Transcription

1 Data sheet H B HPGA high precision generic arm The HPGA is a motorised tool setting arm, for use on both CNC lathes and grinding machines. The patented rotary kinematic design ensures highly repeatable stylus positioning each time the HPGA is rotated into its ARM READY position. The HPGA provides improved repeatability in all three major machine axes. With the innovative new SwarfStop seal design, it can withstand the harshest of environments.! CAUTION: The HPGA is designed specifically for use with the TSI 3 and HSI interfaces. Do not use the HPGA with any other interface. System components Hub and base assembly The hub and base assembly is a fully sealed, compact design that supports a wide range of customer specific arm configurations. The plug and socket connector on the hub and base assembly allows the user to detach the cable easily thus simplifying installation and in the field replacement. Probe module The hub and base accommodates either the LP2 compact probe or the high accuracy strain gauge probe, MP250. HSI and TSI 3 interfaces The HSI and TSI 3 are hard-wired transmission interfaces, which convey and process signals between the inspection probe and the CNC machine control. Both interfaces are DIN rail mounted and signals from the probes are split between the two interfaces. Benefits Tool setting times up to 90% faster. The hub and base assembly is manufactured from cast iron material. The improved hardness results in improved repeatability. 3 μm (2σ) repeatability in all three machine axes. Improved reliability in both grinding and normal machining environments with new seal design. Strain gauge compatibility for improved repeatability and multi-axis directional performance. The arm to hub mechanical connection is non-permanent and thus suitable for a selection of appropriate arms during machine build. Sealed to IPX8 (static).

The TSI 3 interface will show a probe open condition whatever the status of the MP250 probe. For this reason the TSI 3 probe output must be ignored and the probe status from the HSI interface used.
