Flat Lapping

Flat lapping both single-sided and double-sided machines allows us to hold the tightest tolerances, flatness and finishes, It is also used to economically establish a flat surface on flexible or odd-shaped parts prior to machining.  Since lower stresses are induced, little distortion occurs compared with conventional machining or grinding on thin parts, parts made of dissimilar material, or stress and heat sensitive materials like stainless steel.

Grind Lap's lapping machines are Speedfam models ranging in table size from 20" to 64".  We mainly use silicon carbide, aluminum oxide and diamond abrasives for various applications, allowing us to hold sizes and dimensions to very close tolerances; within .0002" in production with flatness requirements of one helium light band (.000012") on many parts.

The variety of parts we lap ranges from large hydraulic castings to small ceramic or carbon seals. Grind Lap has been able to save our customers time and money by combining lapping with our blanchard or double disk grinding to achieve fast stock removal and close tolerances.
