Tool changer alignment gauges verify proper alignment between the tool changer spindle. Improper alignment can result in abnormal wear on the spindle interface, tool changer, and tool holder. In addition, mis-clamping and dropped tools can also occur. HSK-F80 gauge can accept pins for Makino Flange-Pin spindles. For non-standard HSK configurations, please contact us. HSK taper sets include taper and flange, axial and radial alignment pins, and a padded carrying case.
