PRECISION GRANITE
®

A leading manufacturer of granite surface plates, accessories and machine bases.
Since 1984 we have strived to exceed our customers' expectations in every way.

We produce our granite products from several types of granite, depending on the customer's needs. Laboratory tests have shown that fine-grained black granites are stronger, denser, and less absorbent than other granites. For this reason precision machine bases, air-bearing surfaces and accessories are best made from black granite.

Our knowledgeable staff can assist you in selecting the best granite for your product, based in regard to uniformity of surface, accuracy, deflection under load, type of use and price.

We are ISO 9001 Certified and our granite is quarried in the state of California.

We also suggest our Protective Granite Cleaner which penetrates the granite surface to loosen dirt, grime and residues. It leaves the surface clean, allowing instruments to slide without the resistance that wears down the precision surface.
