    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.

    Riser

    Riser with 1" Wide Step

    Riser with 2" Wide Step

    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 with Pin

    Retracted

    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.

    Digital Precision Levels

    Image of Product. Front orientation. Levels. Digital Precision Levels.
    You won’t need to choose between precision or convenience with these levels. Their highly sensitive sensor accurately determines level, even when placed on vibrating machinery and equipment. Clearly read the high-contrast display in any lighting conditions – no need to squint to read vials. They stabilize in five seconds after you position them, so you can quickly check the alignment of one part and move on to the next item. You can also view the angle and slope of a surface without a separate tool. When you need to use these levels under machines or in tight spaces between parts, connect them to your smart device via Bluetooth. The free app lets multiple users view readings remotely.
    In addition, the V-shaped indentation on the base means you can rest them on flat and curved surfaces alike. These levels also have a false zero setting lets you set any position as a reference point when you need to replicate angles on multiple surfaces.
    Granite Base—Granite chips off instead of denting or deforming when dropped. It also won’t corrode in wet environments like cast iron or steel, so the base always stays accurate.

    Straight

    Level horizontal surfaces in two directions at the same time with the highest degree of accuracy. The highly sensitive glass vials on these levels sit perpendicular to one another – place them on the corner of platforms and surface plates to check if they’re tilting sideways, forwards, or backwards.

    Mobile

    Image of Product. Front orientation. Surface Plate Stands. Stationary.

    Stationary

    Secure granite surface plates on these stands to ensure a flat surface for accurate measurements. To keep plates from sagging and warping, stands attach to plates at three support points, as specified in Fed. Spec. GGG-P-463c. The welded steel construction offers greater strength, durability, and stability than economical alternatives such as block and wedge systems.
    Mobile—Conduct measuring and inspecting tasks anywhere in your facility. With steel plate casters and hard, durable wheels, these stands support the same capacities as their stationary counterparts. Turn the adjustable screws on top of the stand to level the plate on uneven floors.
    Stationary—Create a permanent setup for routine measurements and inspections. Twist the mounts at the bottom of each leg to level the plate, even on uneven floors.

    Rectangular Plate with Two Ledges

    With flatness tolerances thinner than a strand of hair, these plates give you the flattest possible surface for accurate measurements. They’re typically used as a reference plane to inspect finished products and calibrate precision measuring tools, such as height gauges and dial indicators. Unlike metal plates, these granite plates won’t rust or interfere with nearby electronics. They also won’t warp when temperatures fluctuate. To maintain their flatness and finish, rotate plates regularly and apply granite cleaner (not included) to remove particles without leaving a residue.
    Also Available: Other plate sizes. Please order 2245A999 and specify grade, length, width, thickness, and with or without ledges.
    Laboratory-Grade AA Plate—Best for precision inspections and quality-control work in calibration labs. These plates have the tightest flatness tolerance for the highest level of accuracy.
    Inspection-Grade A Plate—Your go-to for general inspections and quality-control work. These plates are slightly less precise than grade AA plates with double the flatness tolerance.
    Toolroom-Grade B Plate—Suitable for checking routine measurements throughout a shop. These plates are the least precise with four times the flatness tolerance of grade AA plates.
    Rectangular Plate with Two Ledges—Choose these plates if you need to mount fixtures and instruments with a clamp.
    Black—Harder and denser than red plates to handle heavier loads, such as large bearings and other machined parts.
    Red—Resist wear better than black plates to last up to five times longer. With a higher percentage of quartz, you can slide parts across these plates without worrying about nicks and scratches.
    Surface Plate Covers—Prevent dust and debris from accumulating on plates when you’re not using them.
