Lubrication is necessary for a smooth running condition between the lap plate and conditioning rings and to help evenly disperse the diamond product on the lap plate. Lubricants used with any diamond compound or slurry should be compatible with the carrier in order to give the best cutting action possible, maintain even dispersion of diamond throughout the lapping surface, and produce uniform finishes. The proper lubricant in conjunction with a compatible compound or slurry will reduce lapping time and reduce the amount of compound or slurry needed to complete the job.

Lapmaster lubricating fluids have been developed specifically to work with all Lapmaster diamond compounds and slurries to maximize cutting and polishing efficiency.
