Installing the Z-Axis Limit Block Adjusting Rod

Quick answer

Install the Z-axis limit block adjusting rod on your HiTorque large bench mill with LED controls by aligning it with the sensor block and securing it firmly. Correct placement ensures the Z-axis sensor triggers precisely at the travel limit.

Installation steps

1. Power down and lock the head: Turn off the mill and disconnect power. Lock the head in place to prevent accidental movement during installation. Never work on the sensor with the machine powered.
2. Locate the Z-axis limit block: Find the sensor limit block on the column. Loosen the mounting screw just enough to slide the adjusting rod into position. Do not fully remove the screw; keep the block loosely held.
3. Align the rod with the sensor: Position the rod so it aligns with the sensor's contact point. The gap should be minimal but not touching, allowing the sensor to trigger cleanly. Check the gap by manually moving the head—adjust if the sensor doesn't trigger.
4. Tighten and verify: Tighten the mounting screw securely. Manually move the Z-axis to confirm the sensor triggers at the desired limit. Re-adjust if needed. Test the full travel range to ensure the limit stops the head correctly.
