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
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.
Use the Correct Diamond Tool
Select the correct diamond tool for each job and make sure the proper tool is being used on the job. The proper
tool depends on the grinding wheel and finish required. There are no absolute rules for the selection of diamond
Single points can be replaced by cheaper multi-point
tools or more efficient diamond rolls. For the best results consult our diamond tool engineers for each application.
