Advantages of the Quantum MG 3 Rolls Variable Axis:
The MG 3 roll plate bending machine is characterized by its user friendliness. 

Advantages are various:

Working speed, only one operator is required.
Working can be made in one only pass, following the steps here below:

  • Working speed, only one operator is required.
    • The plate is fed into the machine horizontally thanks to the support of the two side rolls.
    • The plate is instantaneously squared thanks to a line, purposely dug into the rolls, which gives to the operator a straight line to follow.

    Motorization: Replacing of all low efficiency components (gears, bushings, mechanical gear boxes, transmission belts, sliding guides…) with the most efficient epicycloidal gear boxes DIRECTLY COUPLED on the rolls, bearings and hydraulic motors, this way all machine strength is focused on the material to bend (positive strength) with consequent Energy saving. This system conforms to the “International High efficiency and Anti-Pollution” standards. A 4 roll plate bending machine motorization is made of two hydraulic motors, directly assembled to the rolls by particular motion transmission gears and gear boxes that gives the maximum performances with the minimum possible strength. The motion is given to the motors trough a hydraulic pump, which is set in action by an electric motor, it is successively given to the inductors and then to the rolls.Furthermore, motorization is very important during the pre-bending phase, it allows to position the plate at the center of the rolls with the maximum precision, without losing it. This is due to the fact that we are using a 4 roll machine, and can pinch the plate with the central rolls, thus, to get a pre-bending that will not be over 1.5 or twice the plate thickness itself. Furthermore, motorization is very important during the pre-bending phase, it allows to position the plate at the center of the rolls with the maximum precision, without losing it. We will get this way a pre-bend that will never be bigger than 1.5 to twice the material thickness.

    Rolls Cambering / Crowning

    Rolls Cambering / Crowning: A good part of the Quantum MG technology is the application on rolls of a variable cambering on the basis of material thickness. Each Quantum MG machine is different from the others even among same models because the rolls do not have the same cambering. Furthermore, during the bending work a particularphenomenon takes place, a phenomenon that is not always visible : the rolls get subject to deflection, but,  thanks to the cambering, they do not reach the breaking point, and grant the very good result in their bending performance.

    Permanent Lubrication System

    Permanent Lubrication System: Thanks to the using of high quality and high resistance materials, can grant a system of permanent lubrication. By using auto-lubricated bearings it will be enough only to grease the parts during the assembling. Quantum plate bending machine’s maintenance won’t be a problem, only a periodical refilling of the oil will be necessary. All machine components are pre-lubricated and sealed following a unique system granting lubrication for the whole machine life.

    High Effeciency and Energy Saving

    High Efficiency and Energy Saving: We replaced low efficiency components (gears, bushings, transmission belts, sliding guides) with the best planetary / epicyclic gearboxes DIRECTLY COUPLED on the rolls and the hydraulic motors. All the machine strength is focused on the material to bend (positive strength) with consequent Energy saving and machine efficiency.

    Top Roll Contrast to Eject Pipes

    Top Roll Contrast to Eject Pipes: When the machine is endowed of conical bending device, Quantum Machinery uses a system called contrast to eject the pipe. Our system is composed of a piston, on the back side of the roll, that monitors the yoke position, when it’s down, the piston moves and lifts the top roll to let the operator eject the pipe without problems. The monitoring is made by a sequence valve that “feels” the pressure increasing in the hydraulic circuit when the yoke opens, transferring it to the contrast piston that lifts the roll. If the machine is CNC controlled, a pressure gauge is mounted on the sequence valve: it has the task of monitoring the pressure when the yoke closes, stopping the flow in the system.

    Flat Part "The Shortest Unbent Flat"

    FLAT PART "The Shortest Unbent Flat": With our plate rolling machine, the short flat part will be only 1.8 times the plate thickness. Yield point and material thickness can influence the final results, but with our Quantum Plate Rolls you always get the shortest unbent flat. See our pre-bending factors.

    Conical Shapes

    Conical Shapes: 
    Conical bendings with a conicity over 2 degrees reduce machine performances. This is due to the unbalanced load on the top roll and its bearings. The more is the cone tilting the more the machine performance will decrease, till a maximum of a 50% in length and in bending thickness. 

    Tight Minimum Diameters

    D min (Full Capacity) = 3 times the top roll diameter.
    D min (60% of Capacity) = 1.1 times the top roll diameter.
    Quantum Plate Bending Machines are designed and built on a basis of 260 N/mm2 yield point material.

    The minimum possible diameter to be bent depends on several factors such as:

    • Top roll diameter
    • Plate thickness
    • Material

    The machine top roll diameter influences the performing of the minimum diameter for the simple fact that we won’t get a lower diameter than the top roll one.
    As for the plate thickness, let’s say we are using a machine with maximum capacity 100mm, on a 3mt length. We wish to bend a plate working at the maximum capacity. In this case the minimum possible diameter we’ll get will be three times the top roll one. Let’s say now we wish to use the same machine at 60% of its maximum capacity, the case we wish to bend a 3mt plate with a 60mm thickness. At this point the minimum diameter we get will be 1.1 times the top roll one.


    Pre-stations are referred to materials with a yield of 260 N/mm2.

    An increase in material mechanical strength, i.e. Yield Point, or Tensile Strength, will reduce the machines pre bending & rolling capacities, by the factor ‘K’ (see chart below).

    CNC EVO Control


    Touch Command EVO is the latest version of our CNC system completely integrated with Quantum Plate Rolls, built through years of first-hand experience. The control retains its easy to use interface that our customers have enjoyed; underneath it there is a new extremely powerful engine which delivers a precision of control never before found on a plate rolling machine. This is mainly achieved by the new closed loop system, which constantly monitors the rotation and side roll positions.

    There are some challenges when it comes to designing a true CNC control for a plate rolling machine: the main one is the difference in yield tolerances of the material being rolled. Quantum has taken the unique approach of designing a material library that can be adjusted to work specifically with the material you are receiving. This is done by making test bends with your specific material and inputting the diameters that were actually achieved.

    Once this is done and the computer understands how your material reacts or springs back, it can accurately auto-generate programs of virtually any shape required with the material you adjusted the library for: round, square, triangle, elliptical.

    We recommend Quantum's automated controls for high volume cylinder and shell production, or to roll complex shapes that are not easily reproduced by using manual machine controls. Multiple bends, variable radius bends, ovals and the like are some examples.
