Turn the Diamond Frequently The single point diamond tool will sharpen itself when turned frequently. A sharp diamond will dress the wheel with fewer passes. Dressing jobs are quicker with less wheel and diamond wear. A diamond that has been frequently turned develops many facet like cutting edges as shown below. The shank will have several set screw marks around the diameter. The worn tools can frequently be re-set to expose a new point on the diamond for a cost much lower than the price of a new tool. |

| Never Force A Diamond It time to get a new tool after a diamond has ceased to cut freely. A flat diamond force against the grinding wheel will crush the grains. The wheel tends to burnish the work. Forcing a dressing tool can burn the diamond and ruin the tool. |
|||
| Never use a Flat Diamond Flat diamonds create extra dressing pressure. On thin edge wheels found on thread grinding machines, the extra pressure may break the wheel. On a thin edge wheel always start dressing at the tin edge and work back to the thick part. |

| Grinding Machines Should Warm Up Before
Dressing Make sure that the spindle bearings have been warmed up and the coolant is equally distributed throughout the wheel before dressing. If you start dressing cold, the wheel balance and position my be considerably different than after the machine becomes stabilized. |
|||
| Dress Close to the Grinding Position Position the dressing diamond as close to the grinding position as possible. This will greatly reduce any taper due to worn ways on the wheelhead or table. |
|||
| Keep Accurate Records Actual records should be kept of pieces ground per dressing for production grinding. Often dressing time can be reduced and wheel life extended by dressing before the maximum number of parts. Good records help create good production process sheets. |
