Numerically Controlled Four Roll Planetary Axis - (Model No. 4R ---- PANC)

The pre bending / edge bending and rolling can be performed in the same machine.

Advantages :
  • The machine can be operated remotely from all around.
  • Since this being a four roll machine the un-bend flat is minimum and smallest possible diameter is much tighter compared to 3 roll machine.
  • Since all roll movement and roll rotation is through hydraulic actuator, only one person is required for operating the machine without efforts.
  • Since all rolls are mounted in roller bearings the electrical consumption is less by 50% compared to conventional pyramid type machine.
  • Most advanced hydraulic circuit using latest technology electro hydraulics to achieve great roll parallel of within 0.2 mm.

Special Features

The machine frame is fabricated from all tested steel plate material. A Die Penetration test is carried out on all weld joints to ensure sound weld quality This frame is subjected to stress relieving, sand blasting and epoxy primer painted for corrosion free long lasting machine life.( Primer paint 160 DFT) The complete body frame is machined in CNC machine to achieve built

A movable control desk is conveniently located on machine. The main panel start / stop buttons and roll rotation fucntion (Reverse / forward) is provided on the same. The Top roll left side position and right side position are indicated separately by four digital meters

A specially designed & built mechanism allows drop end frame to tilt down in horizontal position without much efforts (one person can perform job). No need to dismantle frame from main body like in conventional machine. The top roll can be tilted to great degree of inclination making it most convenient and ease to remove rolled shells without any difficulty

All our machine rolls are mounted in heavy duty roller bearings. Each roller is fitted with two bearing per side (four bearing per roller)

A dual cone bending device can be provided as shown. The attachment provided between bottom rolls is suitable for narrow cone diameter. The attachment to be fitted on a main frame is suitable for cone having wide angle.

An extended rolls can be provided for mounting dies to roll different sections like angle, channel, beam, pipe or flat etc.

Tilt able top roll makes it more convenient to remove rolled shell with ease
