PTG Heavy Industries have built machine tools that cover a vast range of applications and we are always willing to listen, advise and propose solutions to whatever task is presented.


Over the past 40 year Crawford Swift has designed and built a number of special purpose machines, typical examples of which are as follows:


  • Vertical Turning machines

  • Vertical Roll Turning Machines
  • Acrylic Polishing Machines
  • Roll Marking and Notching Machines
  • Rotor Slot Milling Machines
  • Roll Grinding Machines
  • Roll Texturing Machines
  • Roll Loaders
  • Chock Manipulators
  • Hosan In Line and Rotary Transfer
     Machines

  • Hosan Spindles

 


SPECIAL PURPOSE VARIANTS:

Sliding Gap Bed Lathes:
The sliding bed allows components up to 3000mm (118") in diameter with varying lengths to be accommodated. When closed the machine reverts to a standard DATA lathe configuration, typical applications are Aircraft Under Carriage, Crane Hook and Sheave manufacture.

T bed Lathes:
The T bed series offer many advantages over standard machines for large diameter chucking applications, including easy loading and access, plus greater stability for machining across a large diameter face.

Offset Bed Lathes:
Allows components up to 3000mm (118") in diameter and 10,000mm (394") in length to be machined efficiently and is ideally suited to Drum or Roller turning applications.

Thread Whirling Machines:
Ideal for the manufacture of Ballscrews, Actuator Screws, Extruder Screws, Worm Shafts, Cams and other Helical Path machining.
