GENERAL RULES
SUGGESTION FOR LAPPING
TYPES OF LAPS

Clean workpiece thoroughly before applying diamond compound
and between successive grades of finer diamond compounds.
Lap material shall be softer than the workpiece.
Use minimum amount of diamond compound for each operation.
Use separate lap for each grade of compound.
Maintain correct speed --avoid excessive speeds.
Maintain desired lubricity by applying I-D-L lapping oil.

 
Cold rolled steel, cast iron (meehanite), copper, brass, plastic, rock
maple, wood, paper, felt, and cotton.
Harder laps are used with the coarser grades of diamond compound,
and the softer laps are used with the finer grades of Diamond compound.
Harder laps have a faster cutting action, while softer laps have a
slower polishing action with a finer finish.
SELECTION OF GRADE OF DIAMOND COMPOUND
GENERAL RECOMMENDATIONS
Normally the harder the workpiece the higher the concentration of
diamond compound
For greater efficiency and economy select concentration of diamond
compound based on the hardness of the workpiece.
Mesh sizes are used for fast cutting, hogging and ripping operations.
Micron sizes beginning with #45, 30 and 15 are used for Fast, Medium
and Light cutting in the proper sequence.
Micron sizes #9, 6, 3, 1, 1/2, 1/4, and 1/10 are used in the proper
sequence for intermediate to super finishing.
