Granite Flat-Surface Plates


Corrosion resistant and nonmagnetic, these smooth plates also resist warping and abrasion. The extremely tight flatness tolerances provide an accurate reference plane for layout and inspection work.
Plates with two ledges are used to hold fixtures and instruments with clamps.
Laboratory Grade AA plates are for precision quality control work.
Inspection Grade A plates are for general quality control work.
Toolroom Grade B plates are for checking work throughout a shop.
Also Available: Other plate sizes. Please order 2245A999 and specify grade, length, width, thickness, and with or without ledges.

Vacuum Workholding Plates
Also known as vacuum chucks, these plates secure thin and flexible parts that can’t be held with vises or clamps for milling, drilling, routing, and finishing operations. Connect the system to your shop’s compressed air supply and it's ready to use. For applications requiring only part of the plate surface, use the gasket cord to seal off the area.
Risers, also known as vacuum pods, raise the workpiece off the vacuum table to give the cutting tool better access. Suction transfers from the table through the top of the riser, so to get a firm hold the workpiece must make contact with the full top length and width of the riser.
Retracting stop pins let you repeatably locate parts on your vacuum table. After positioning your workpiece against these pins, turn on the vacuum and the stop pins retract, dropping out of the way so the cutting tool has full access to the workpiece.
Side stops fit into the grooves of the vacuum plate to help you repeatably position material. They can be removed from the plate after the vacuum is turned on to give the cutting tool more access to the workpiece.
