The three roll planatory axis is a three roll machine having pre pinching/pre bending facility within the machine. The plate can be inserted from one side and is clamped between top roll and one of the pressure roll for a firm grip and the another pressure roll advances further to form desired radious of shell. The same procedure is repeated but on another side of plate to form desired radiouse. After having done pre pinchind the plate is formed in to circular shape by rolling and further pressing of pressure rolls and by forward and reverse movement of rotation by rolls. Usually a shell is formed in multiple passes of rolling by forward and reverse movement of rolls in rotary motion. It is also possible to form shell in a single pass provided the pressure roll position is well known for particular size of shell rolling by regular practice and experience. The PLC based machine is most suitable for repetitive type of jobs and shapes required regularly Other shapes can also be forme in this machine in single pass like square, polycentric,elliptical or open rolling.

Standard Featues

 All 3 rolls are positively driven by in line mounted planetary gear box and hydraulic motor Roll parallelism maintained by solid linkage mechanism
 Digital display for roll position for ease of rolling and for fast rolling of repetitive type components
 Spherical roller bearings are used as standard in all our models
 Heavy duty reinforced steel frames duly stress relieved and epoxy painted after sand blasting

Optional Features

 Electronic proportional balancing using hydraulic system specially developed for plate bending a machine
 Induction Hardened rolls for 52-55 RC hardness
 Conical bending device
 Provision for section rolling
 Section bending dies
 Overhead support
 Lateral support
 Auto plate squaring reference stopper
 Tilt able top roll
 Automatic roll speed compensation

Advantages

 More suitable for small engineering work shop where bending requirement in small quantities and in different sizes as per job requirement
Less costly compared to 4 roll machine, hence low initial investment
 Both leading and trailing edge can be pre bend in single pass. No need to remove and reinsert material
 Small engineering workshop willing to invest less still automate rolling
Open type rolling requiring mass production quantity
 Can use as a straightening machine for pre formed material for reuse
 Can use where different operations like pre bending, rolling, material straightening ,Conical rolling, section rolling need to be carried out in single machine.
