Static edge finder and tool height gauge for computer numerical control (cnc) machines

A static edge finder for finding an edge of a workpiece loaded in a CNC machine, the static edge finder comprising:

• a body having a distal end and a proximal end;
• an opening formed in the distal end of the body and extending toward the proximal end of the body, the opening terminating in a shoulder;
• a slot formed in the body and communicating with the opening;
• a plunger having a distal end and a proximal end, the proximal end of the plunger being disposed in the opening of the body and the distal end of the plunger extending out of the opening of the body;
• a spring disposed between the proximal end of the plunger and shoulder of the opening;
• and
• a retaining pin mounted to the plunger and extending through the slot;
• wherein the static edge finder is configured to be mounted to a spindle of the CNC machine to find the edge of the workpiece loaded in the CNC machine.
