1. The Component

• Material type and constituents.
• Material hardness.  This should be well controlled within the tolerance band.
• Stock removal.  Should not be excessive and should be evenly distributed for optimum wheel performance.
• Pre-grind controls.  Should be tight enough to ensure consistent component conditions.

2. The Machine Conditions

• Rigid construction in the machine tool
• Accurately controlled feed systems
• Grinding spindle.  Rigid with sufficient number of bearings.  Sufficient speed and power are important.
• Rigidity should be followed right through to the wheel with the use of Tungsten Carbide or Heavy Metal quills engineered with a precise location for the wheel whenever possible

3. The Dressing Facility

• Rotary High Frequency, hydraulic, or stable pneumatic dressers in conjunction with adequate bearings.
• Preferably a metal bonded, ceramic, or electroplated diamond cup or disk of larger grit size than wheel.
• Precise control over dressing in feed of 0.001-0.005 mm (0.00004-0.0002 in).
• Initial dressing of the wheel is critical, in preparation for the grinding operation.

4. The Coolant Supply

• The choice of oils, water-soluble, synthetics, or semi-synthetics must be carefully matched to the particular application.
• The system should have sufficient pressure and flow rate to ideally match the speed of the wheel, especially in creep feed applications.
• Nozzles should be positioned to direct the coolant to the point of contact in the grind zone.
• An adequately sized and clean filtration system is recommended.
