(5) Precision lapped in laboratory and inspection grades. Granite Angle Plates can be furnished with either two surfaces (base and face) or four surfaces (base, face and both ends) finished.
(4) Precision lapped in matched pairs in laboratory and inspection grades. Granite Parallels can be furnished in matched pairs with either two faces or four faces parallel.
(5) Precision ground and lapped to laboratory and inspection grades, these straight edges are finished on one narrow surface as standard. Both narrow surfaces can be finished in a straight and parallel plane when required.
(5) Precision ground and lapped to laboratory and inspection grades. Granite Master Squares are finished on all four 3" surfaces and one large face. They provide unlimited versatility for a wide variety of inspection applications
(5) Precision ground and lapped in matched pairs to laboratory and inspection grades. Granite V-Blocks have nominal 90° V centered and parallel to the bottom with two sides and square to the ends.
GRANITE PRODUCTS are extremely hard and durable but must be handled carefully to avoid chipping and shock damage. While not subject to corrosion, granite products must be kept clean and used on clean surfaces to avoid scratches and wear that can alter the precision tolerances. An alcohol base Precision Surface Plate Cleaner is recommended for regular use in maintaining the cleanliness of surface plates and accessories. The cleaner is packaged in quart and gallon containers.
WHEN NOT IN USE, surface plates and accessories should be covered. Surface plates should not be used for storage. Especially heavy objects can disturb the flatness tolerance. As with all equipment used in close-tolerance quality assurance, granite ...
