Double Sided Lapping

	Our double sided lapping machines can give you the volume efficiency that you are looking for.

Picture all of the advantages of single sided lapping and more! Lapping both sides at the same time means less part handling and less time in the machine, thus, saving you money!

• Higher production rates because you are doing two sides at once
• Greater size control: +/- .000020 (20 millionths of an inch)
• Better parallelism: .00002 of an inch
• Flatness: .000011" (one eleventh million of an inch)
• Finish: 4 microns

We now have 2 Peter Walters Double Sided lappers. These machines are state of the art, with P.L.C. By having two similar machines, the scheduling is a lot easier and allows us to have one machine with a fine abrasive for finish work. The other one is usually a coarser abrasive and is used for work having higher stock removals.

The machine consists of working tables of 1200 mm (47-1/4") in diameter with 7 carriers that move the work pieces across the entire table. These machines are equipped with "MAHR" size control and programming capabilities. This equipment is very capable of high precision type work.
