MMR diaphragms are used with SMR series top jaws which are bolted on from the rear of the diaphragm. This eliminates the possibility of having an interrupted clamping diameter since there are no counterbored mounting holes in the top jaws. MMR diaphragms are also available in 2, 3, and 8 jaw configurations.

Design
Self-contained design with built-in air cylinder. Air ports are located on the side of the chuck body for stationary use.Application
OD and ID chucking for milling, drilling, inspection, or any other non- rotating application requiring high concentricity and/or close workpiece roundness. The inherent spring characteristic of the diaphragm allows workpieces to be clamped without continuous air supply for pallet and tombstone applications.

  • MBS/L Air Operated Diaphragm Chuck

    Design
    Self-contained design with built-in air cylinder. Air is supplied to the chuck by a multi passage air tube assembly with a rotary coupling. Coolant through the spindle capability is standard.

    Application
    OD and ID chucking for cylindrical grinding, turning, and hard turning. Ideal for workpieces requiring high concentricity, and/or close round ness. Ideal for fragile parts which are easily distorted, and applications requiring high spindle speeds.

  • MBS/Z Draw Bar Operated Diaphragm Chucks

    Design
    Draw tube operated design. Can be actuated with either a hydraulic or pneumatic cylinder mounted at the rear of the machine spindle.

    Application
    OD and ID chucking for cylindrical grinding, turning, and hard turning. Ideal for workpieces requiring high concentricity, and applications requiring high chucking force and/or high spindle speeds.

  • MBS/N Stationary Diaphragm Chucks

    Design
    Self-contained design with built-in air cylinder. Air ports are located on the side of the chuck body for stationary use.

    Application
    OD and ID chucking for milling, drilling, inspection, or any other non- rotating application requiring high concentricity and/or close workpiece roundness.

    Air tube assemblies are used with MBS/L chuck models. The rotary air coupling features a hardened steel journal and a maintenance free oil- lite bearing.

    Rotary air tubes include a blank support bushing, air hoses and fittings. Length to be specified when ordering. Contact our sales department for assistance in determining the correct length for your application.
