ATC ALIGNMENT TOOL Misalignment of the center between the machine tool spindle and ATC gripper may cause damage to the spindle taper when a tool holder is loaded into the spindle. A clamped tool holder under misalignment leads to increased runout, resulting in shorter life of machine tools and tool holders, as well as cutting tools. The ATC Alignment Tool can also be used for re-aligning the ATC gripper and tool magazine pots. Overall cost reduction is achieved by using equipment in good condition. How To Use 1. Load the AL Shank in the machine spindle and mount the AL Flange on the ATC arm. 2. Insert the AL Plug into the AL Flange. 3. Rotate the AL Plug and read the highest and lowest values of the dial indicator. This direction is the eccentric direction. Half of the gap of the values is the eccentric amount. 4. Adjust the position of the ATC arm so that the front end of the AL Plug will be inserted into the AL Flange fully.
