ARLA^® Endworking & End Preparation Machine

Complete CNC Machine Tool for Single or Double Sided Machining

In order to realize a reliable endworking (end preparation) of pipes, tubes, and shafts ARLA offers complete CNC machine tools based on the industry proven ARLA machining units (spindle, slide, table units) including workholding systems to clamp workpieces concentrically. All machining units are directly driven by servo motors and are controlled by a powerful CNC. The units and the workholding systems can be adjusted and positioned in longitudinal direction according to the technical requirements of the manufacturing process. You may feed the workpieces from top by special handling systems which are designed for the transportation of pipes in finishing lines for example. As the clamping technology is based on a concentrical workholding, the accuracy referring to the workpiece centre can be always achieved independently of the workpiece diameters (ODs). There are flexible stops in order to define an exact position.

Typical ID/OD machining operations are:

• Turning
• Facing
• Tapping
• Threading
• Grooving
• Chamfering
• Deburring
• Contour Machining
• Boring, (Center) Drilling

• Milling
• other special applications

Typical max.workpiece diameters (ODs): 61, 115, 170, 220, 275, 325 mm
(pipe size: 1-2”, 3-4”, 5-6”, 8”, 10”, 12”)

Workpiece lengths: 100 – 500 / 1000 / 1500 / 2000 / 3000 mm (other lengths on request)

The complete CNC endworking machine can be designed for single-sided or for double-sided operation.The machine concept is structured as follows:

• Basic Model EU
  compact station for the single-sided machining of workpieces with undefined (unlimited) lengths
• Basic Model EM
  machine with a complete frame for single-/double-sided machining operations with 2 clamping stations for the workpiece
• Models EUA, EMA with a directly driven spindle
• Models EUB, EMB with integrated, water-cooled motor spindle
• Models EMC (like EMB), however with additional tool changer systems
• Models EUX, EMX with motor spindle including an integrated facing equipment

Special models of the ARLA workholding system are available on customer's request.
