MCP-Series 5-Axis Concentric Vises
Mechanical or Hydraulic Operation

  • MCP-series 5-axis vises have optimal features to allow unrestricted tool access for multiple-side machining.
  • Z-series MCP vises are dimensionally similar to the standard fixed-jaw version but incorporate our precision self-centering mechanism. Concentric vises have two moving jaws that provide clamping at the exact center of the rotary table.  MCP-Series 5-Axis Concentric Vises are available in the four sizes shown below, with the following jaw widths: 

 

  • 40mm      Mechanical
  • 60mm      Mechanical or Hydraulic
  • 100mm    Mechanical or Hydraulic
  • 125mm    Mechanical


Internal Clamps

Internal clamps expand to clamp on the inside diameter of a workpiece, leaving the outside clear for machining. Internal clamps are self-centering to simultaneously locate and clamp.

Fixture Clamps – Concentric

Concentric Fixture Clamps are extremely compact, high-precision power vises designed to be incorporated into workholding fixtures.

 

Unlike standard vises, Concentric Fixture Clamps do not have a leadscrew for adjustment – instead using exchangeable, machinable clamping jaws that must be custom sized for the workpiece. The concentric version of Carr Lane fixture clamps is designed to center and clamp a workpiece using an exterior contour as a reference surface. Features high-precision centering with +/-.0008" repeatability. Available in two sizes, 40mm and 65mm jaw width.
