Surface grinders are machine tools for very precisely removing small amounts of metal. Grinding operations are suitable for hardened tool steels. Parts are often milled slightly over-size in the annealed state, then heat treated, and surface ground to final dimension. Surface grinders can be over 10 times more precise than milling machines, but are only suitable for very light cuts.

Personal Protective Equipment

  • Standard shop personal protective equipment (safety glasses, no long hair, no flowing clothes, etc.) are required
  • ABSOLUTELY NO gloves, rings, bracelets, or other items on your hands or fingers when holding the work, as these may get sucked into the grinding wheel
  • Respiratory protection recommended for grinding dust

Safe Operation

  • 0.001" MAXIMUM depth of cut
  • Inspect wheel before use
    • Chips and cracks can cause wheel to explode during use, if in doubt tag out wheel for inspection by Artisan’s Asylum staff,
    • Wheel must have paper blotters on both sides
    • Wheel should be centered and balanced on hub, and hub tightened
  • Securely hold workpieces to the magnetic chuck, adding blocks on left side of part if necessary, or hold part in a grinding vice
  • Allow grinding wheel to come up to speed before grinding
  • Only grind on the face of flat grinding wheels, never on the sides
  • Use proper cup or dish wheel for side wheeling
  • Dress wheel before use to minimize heat buildup
  • Keep hands away from wheel, if manipulating workpieces with spindle on, move table completely to one side and lock and move table completely out
  • Adjust height off workpiece, do not plunge
  • Make sure all guards are in place

Common Maintenance Operations

  • Check to make sure the grinding wheel is not chipped or cracked before any operation. Damaged wheels should be replaced or otherwise addressed by Artisan’s Asylum staff

Allowable Materials

  • Metal only.
  • Check if a wheel is rated for non-ferrous (aluminum, brass, etc.) or ferrous metals before grinding.
  • Absolutely no non-ferrous metals on iron oxide (ferrous) wheels, as there is a significant risk of wheel explosion
