Grinding Exterior Keyway

Use cutoff grindger wheel and guide, then use a dremel to clean up:

Brute force with grinder:

Summary of grinder route:

  1. Use cutoff grinder wheel with guide to make the sides. Use a guide clamped on the shaft. This provides the straight, vertical edge
  2. Use a larger grinder wheel to bore out between the sides.

Universal Axis

  • Simply mount a needle file on a Universal Axis - based reciprocator, and let it CNC all night long to make a perfect keyway very slowly. With 10 micron step size, this should not be a problem. Working out functional parameters would be a good project for a student. Needle files: [1]
