To dress the grinding wheel:
1.Insert the diamond tipped dressing tool into its base (Figure 32), and use a 4mm hex wrench to tighten the locking set screw.
Figure 32. Dressing tool setup.
2.Lower the headstock so the wheel is approximately 5mm lower than the tip of the dressing tool.
3.Position the tip of the dressing tool at the trailing side of the wheel, as shown in Figure 31, and move the table inward until the diamond tip of the dressing tool slightly touches the edge of the grinding wheel. Verify by manually rotating the wheel and listening for contact.
4.Turn on the magnetic chuck, and move the cross slide so the tip is free of the grinding wheel.
5.Start the grinder, and use the cross slide handwheel to progressively move the table, so the diamond sweeps across the wheel at a depth between 0.01 – 0.03mm.
Wheel Balancing
Static wheel balancing can be difficult and very time consuming without practice. For accurate grinding results, wheel balancing is mandatory. For this balancing procedure, you will need a wheel balancing fixture. The wheel balancing fixture shown in Figure 33 is one example of the many varieties available on the market.
Before proceeding, the grinding wheel must be ring tested (refer to Page ) and dressed (refer to Page ).

If flood coolant was used with the grinding wheel, run the machine with the grinding wheel installed for
To balance the grinding wheel:
1.DISCONNECT MACHINE FROM POWER!
2.Set up the wheel balancer as outlined in its product user manual.
3.Remove the grinding wheel and hub as a unit from the spindle as outlined in
