Surface Plates & V-Blocks
Every measurement made with a height gauge, indicator or V-block is made against a reference plane. The granite surface plate is that plane; a V-block holds round work with its axis parallel to it, and parallel sets raise the part to the height needed in a machine vice and on the plate.

Granite surface plates
A plate's accuracy is given by its DIN876 grade: grade 00 for calibration and the laboratory, grade 0 for inspection and precise shop measurement. Size follows the largest part to be worked on it and the height gauge's travel.
A plate should rest on three points; granite stands are built to carry it there, which keeps it flat.
V-blocks and parallels
A V-block holds shafts, tubes and round parts on a fixed axis for runout and concentricity checks and for marking out. Clamp V-blocks grip the part; magnetic V-blocks hold steel by magnet. V-blocks used in pairs must be matched.
Frequently Asked Questions
What is the difference between grade 00 and grade 0?
The flatness tolerance. Grade 00 is roughly twice as flat and is used for calibration and laboratory work.
How should a granite plate be cleaned?
Wipe off dust and swarf with a soft cloth and use a granite cleaner. Do not leave oil or coolant standing on it.
