How to True a Diamond Wheel

Diamond wheels allow users to grind or cut hardened materials that render other types of grinding wheels ineffective. When you use any new wheel on a machine -- or after repeated use of an existing setup -- you need to true it to make sure the wheel runs properly and acts like it should. Truing a wheel requires the use of a special tool to grind down the grinding surface of a wheel to make it run concentric with the machine's spindle. Truing a diamond wheel works the same way as truing any other wheel, but you need to use special materials to affect the hard diamond surface.

Things You'll Need

  • Wax crayon
  • Dial indicator
  • Truing device with aluminum oxide or silica carbide wheel
  • Aluminum oxide or silica carbide dressing stick

Instructions

    • 1

      Color the entire grinding face of the diamond wheel with a brightly colored wax crayon. Leave no portion of the grinding face uncovered.

    • 2

      Clean the machine's spindle and the hub of the diamond wheel thoroughly. Remove all pitch, wax, oil and any other residue or debris.

    • 3

      Lock the truing device into place underneath the machine's spindle, making sure to leave enough space to mount the wheel afterward. Make sure the truing device's spindle aligns parallel to the machine's spindle to within 0.001-inch.

    • 4

      Slide the diamond wheel onto the machine's spindle and lock it into place. Mount the wheel as concentric to the machine spindle as possible, checking the setup with an indicator and making adjustments as necessary.

    • 5

      Lower the diamond wheel or raise the truing device until the two wheels almost touch. Stop before actual contact occurs.

    • 6

      Turn on both the diamond wheel and truing wheel. Allow them to reach full speed. For best results, the truing wheel should spin five times faster than the diamond wheel. Make sure both wheels are running in the same direction.

    • 7

      Slowly bring the two wheels together. Listen for the sound of contact. Stop lowering the wheels when contact is made.

    • 8

      Move the truing wheel across the diamond wheel's grinding face at a traverse rate of 30 to 60 inches per minute. Program the truing wheel to feed into the diamond wheel at a rate of 0.0005-inch to 0.001-inch at the end of each pass.

    • 9

      True the wheel until all of the wax crayon is removed from the surface of the diamond wheel. Measure the concentricity of the wheel to the spindle using a dial indicator to make sure the truing process worked correctly afterward.

    • 10

      Dress the trued diamond wheel with an aluminum oxide or silica carbide dressing stick to open up the diamond grits that were worn smooth by the truing process. Hold the stick against the grinding face of the spinning diamond wheel until the surface appears rough and the individual grits are visible.

Tips & Warnings

  • Very large diamond wheels or diamond wheels cut to a specific form require the use of specialized truing tools and setups. Consult with your diamond wheel supplier for more information about truing specialty wheels.
  • Spinning diamond wheels can burn or cut skin. Make sure all safeguards are in place and avoid placing hands or fingers near rotating wheels.
