Key features of our 20 Ton Rotary friction Welding Machines

  • Spindle driven by AC servo motor
  • Rapid stopping of spindle by regenerative braking which saves energy
  • Welding force provided by servo hydraulic cylinders in closed loop control system
  • Pressure transducer/ load cell and linear scale feedback for load and displacement control
  • On-line plotting of important parameters like axial thrust, spindle speed, loss of length and spindle torque during weld cycle
  • Archival and retrieval of weld data
  • Remote customer support through internet
  • Spindle orientation facility for aligned welding

20T Friction Welder with Built-in Pre-machining (Milling) Unit

This 20 tonne machine is designed for welding cable lugs made out of Aluminium and copper (bi-metallic) parts. The Friction Welder has a built-in pre-machining unit for milling the end faces of copper palm and aluminum rod just before welding. This ensures oxide layer free interfaces for quality welding. This machine with tie rod construction consists of a steel fabricated mainframe, which supports all sub- assemblies such as spindle head, tailstock, slide table, forge cylinder, component clamping system and pre-machining unit. It has a standalone electrical cabinet and a hydraulic power pack. Lubrication is provided for all sliding parts. The machine is controlled through a PLC system integrated with an IPC and software for capturing real time wed data.

Specifications
  • Max. forge force : 200kN
  • Max. dia. at weld : 40mm

Designed for welding Cable lugs - ( copper to Aluminium welding )

20T - Dual Sliding Head Machine with Built-in CNC Deflash Unit

This 20 ton dual sliding head machine is designed for welding stub shaft or tripod to tubular shaft at its ends and to deflash the component immediately after welding simultaneously at both ends. Since welding and deflashing are being done at both ends at the same setup cycle time for producing the component is much less than half the time, when compared with doing on single head machine. It has a steel fabricated frame on which LH and RH spindle heads slide on LM guides mounted on its top. A self- centering vice central fixture unit is mounted on the frame for holding the non-rotating part Tripod or Tube.

6T - Vertical Machine for Smaller Foot Print
  • Max. forge force : 200 kN
  • Spindle speed : 0-1500 rpm-Infinitely variable
  • Spindle torque : 210 Nm
Tubular shaft (non-rotating part)
  • Dia. at weld - OD : 60mm max
  • Wall thickness : 5mm max
  • Length : 450mm max
Stub Shaft (rotating part)
  • Dia. at weld : 60mm max
  • Max. Wall thickness : 5mm
  • Max. Length : 250mm
Tripod
  • Dia. at Weld : 50mm max

Designed for welding Stub Shaft / Tripod to Tubular Shaft

Automotive

Advantages

  • Very short cycle time (few seconds)
  • Ideal for mass production
  • Savings in costly material if bi-metallic component is used (Eg. Drills- HSS/MCS)
  • Low heat -affected zone and hence semi finished components can be welded
  • Low energy consumption
  • No edge preparation, filler material, shielding gas, spattering, fumes and radiation
  • Excellent welding: Joint as strong or stronger than parent material
  • Metals as diverse as Cu to Al, Cu or Al to steel, Titanium to stainless steel etc. can be welded
  • 100% in-process quality check
