Work Light/Coolant Mount, Grizzly G0758 Milling Machine

thingiverse

A mounting bracket for installing a flex work light and coolant system on a Grizzly G0758 milling machine allows for optimal visibility without requiring drilling or compromising safety protocols. This modification necessitates removal of the chip guard assembly and minor adjustments to wiring configurations, enabling seamless integration with a flex arm safety shield if desired. Two models are provided: one with and another without the coolant block mount. The lamp used in this setup is an Aglaia 4W LED touch-control lamp featuring a clamp base that was removed to accommodate a longer M6 x 20mm screw for mounting on the printed bracket. The non-conductive material of the bracket prevents electrical interference when touching the mill's bare metal parts, ensuring safe operation. The coolant system showcased in the photograph is an OriGlam mist coolant system attached with two M5 screws and nuts or using plastic ties that offer superior resistance to torque compared to screws along the bottom edge alone. To initiate this installation: 1. Ensure the milling machine is turned off and unplugged from power. 2. Remove the two M5 screws securing the chip guard assembly to the side of the milling head, then save these for future use with the new bracket. Next, disconnect the spade connectors from the safety microswitch inside the chip guard mount before removing it entirely. 3. Remove the four screws that secure the control panel to its enclosure and carefully lower it while letting it hang by the wires as demonstrated in the photo. 4. Unclip the chip guard wiring harness from under the milling head, locate the inline terminal splice connecting a black wire to the brown wire from this harness, and disconnect the brown wire of the harness from this splice. 5. Connect the blue wire of the harness to the splice, thus bypassing the microswitch. Ensure there's enough blue wire to reach from the power switch to the inline terminal splice and cut it as shown in the photo. Remove the chip guard wiring harness from the control box, strip 5/16" of the cut end of the blue wire, tin the wire, and connect it to the inline splice where the brown wire used to be. 6. Verify that all connections are secure, tuck any loose wires, replace the control panel with its four screws, and check the mill's operation to ensure everything is functioning as expected. 7. Install a plastic isolating washer on the lamp base, which comes with the lamp and serves to isolate the metal clamp from the touch base. This washer provides additional surface area for the base and prevents the M6 screw from pinching any wiring in the lamp base. 8. Attach the lamp to the bracket using the M6 x 20mm screw. Then, attach the lamp/bracket assembly to the side of the milling head with the two M5 screws that originally secured the chip guard assembly. The protruding portion and head of the M6 screw should pass through the hole originally used for the wiring harness. The photos also showcase the G0758 spindle lock:
