Numerically Controlled Three Roll Variable Axis - (Model No. 3R----VANC)

This is a machine model available with pre bending facility and most useful for one of / repetitive type of medium and heavy components.

Advantages :
  • Specially developed hydraulic circuit requiring minimum maintenance.
  • Since all three roll position can be varied and placed as per requirement ,the machine gives equally good performance for minimum to maximum thickness within specified range.
  • As the bottom roll axis distance can be varied from minimum to maximum. It covers a wide range of material thickness for pre bending / rolling depending on diameter to be rolled.
  • Since all roll movement and roll rotation is through hydrualic 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.
  • Cone bending is much easy in this type machines.
  • Most advanced hydraulic circuit using latest technology electro hydraulics to achieve great roll parallel of within 0.2 mm.
  • Being NC machine all rolling related parameters can be saved and can be re called again for repeatedly same rolling sizes.

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)

In this type machine all three rolls can be inclined to great degree This makes it most suitable for forming cones with wide diameter difference Also since the machine can work as a press too it can form cone up to full machine capacity If cones are made by press forming method Also a separate dual cone bending attachment can be provided for forming narrow angle cones



Standard Featues
  • All rolls manufactured from alloy steel material
  • PLC & HMI.
  • The top roll is positively driven by inline mounted planetary gear box and hydraulic motor.
  • Possible to place both top roll and side roll in inclined position for conical rolling.



Optional Featues
  • A special alloy steel material for Hardened rolls. Hardness up to 52-60 RC
  • All 3 rolls can be positively driven.
  • A seprate cone bending attachment can be provided for narrow diameter cone forming.
  • Overhead support
  • Lateral support
  • Tilt able top roll
  • Automatic roll speed compensation
