Surface Plate

Starrett Crystal Pink Granite angle plates are used for precise inspection, layout, gauging and marking applications. These quartz-loaded plates provide excellent wear resistance, stability, vibration damping, non-corrosive and equally distributed load-bearing capabilities. They are available in laboratory grade (AA) and inspection grade (A) versions for high precision operations in any temperature-controlled ambience. These units feature 2 or more surfaces with a fine flat finish and also facilitate holding / clamping the workpiece in a vertical position. Choose from a wide range of these granite angle plates available in thicknesses ranging from 100 to 300mm on Raptor Supplies.

Granite tri squares from Starrett offer an economical way to check X, Y and Z axis alignments on CNCs and CMMs for precision layout, inspection and tooling setup. These Grade AA Laboratory and A inspection tri-squares are suitable for quality control. They are available in thickness ranging from 75 to 150 mm. Raptor Supplies offers a wide range of Starrett granite squares, also used for direct checking of squareness and straightness.

Starrett granite straight edges are used for inspection of straightness and flatness of finished components. These straight edges are made from crystal pink granite to ensure exceptional strength and resistance from chipping & scratching. They have a long & narrow face finished flat, and are available in thicknesses ranging from 600 to 1800 mm.

Starrett pink granite cubes are ideal for inspection, maintenance, proper alignment and calibration of any machine. These cubes have six face configurations (with opposite sides parallel and adjacent sides perpendicular to each other), accurately lapped together and feature round edges & corners for ease in measuring straightness, squareness and parallelism of the equipment. They also include a storage case for safely storing the cubes when not in use and are available in 75, 100 and 150 mm thickness options.

Starrett paired granite parallels are designed for setting up workpieces on surface plates and machine tables and elevating work pieces above the surface plate for quick and easy inspection of critical components. These units feature pink granite for maximum wear resistance, durability, corrosion resistance and high tolerance to temperature fluctuations. They are available in AA Laboratory and A Inspection grade variants for accuracy and precision.
