ARLA^® Clamping System (MXR, PXR, HXR)

Centralized Workholding System with Repeatable Accuracy
Standard Models "XR Series": 25 - 50 - 100 - 150 - 200 - 300

Centralized mechanical clamping technology

• various models of the XR series for different max. diameters (OD):
  22 ... 410 mm = 0.86" … 16.14"
  (compatible with the nominal size of steel pipes: 1/2" ... 16")
• slim, compact, stiff design dedicated to extended machining conditions
  with high reliability & solidity
• high clamping forces (5...280 kN) due to the mechanical technology
• extremely short clamping time 0.25…0.8 sec (fast-action clamping technology)
• changeable jaw sets with collars (depending on the workpiece size)
• accurate clamping repeatability
• system also applicable to higher machining loads
  (milling operations, forces in various axes, end preparation operations)
• easy integration into manufacturing lines and special-purpose machines
  (improved assembly either on top or in axial workpiece direction supported
  by the "flange" option)
• also to be used in the automated assembly (e.g. to screw parts together)
• actuation: manual (M), pneumatic (P), hydraulic (H)
• special-purpose units on request (example: clamping of crankshafts & camshafts)

The ARLA Clamping System is a centralized workholding system to clamp round workpieces (shafts, pipes, tubes) or any other symmetrical workpieces. Due to the mechanically synchronous clamping technology a high clamping force can be realized. Workpieces can be put into the system either axially or vertically. The accuracy according to the repeatability is within a tolerance of less than 0.01 mm. Models with either manual (M), pneumatic (P), or hydraulic (H) actuation are available. With reference to the workpiece design, changeable jaw sets are used. The movement of the actuation arms is monitored by sensors. Special accessories (universal clamping plates, swivelling workpiece stops with support and prismatic base, jaws completely manufactured) are also available. Typical applications of this centralized workholding system are found in endworking processes of pipes, tubes, and shafts (end preparation, end fabrication) and also in special-purpose machine tools (transfer lines, rotary indexing table and trunnion machines). ARLA also offers complete solutions for the endworking.
