Machine tool according to customer requirements of automatic cutting different handedness, helix Angle of rib, in roll weeks to any parts or not equal dividing or Spaces; Can automatically on roll at any position of making any kinds of logo you need. Can also according to your requirements for any non-standard roll groove type, text and tag processing. Satisfy a variety of functions and more efficient working you need on this machine .
The milling head is supported by the latest rolling circular guide rail, which solves the rigidity problem of the milling head support, and greatly improves the sensitivity and positioning accuracy of the rotation direction. The engraving/milling motor is driven by a high-power 2.2KW motor to ensure the stability in cutting process.
Machine adopts ball screw transmission (avoid gear rack transmission inaccurate faults), the numerical control system, automatic control, to achieve a pass to the next pass automatically move, precise position, without manual movement.
The tailstock of the machine tool adopts the fixed spindle + high-precision tailstock rotation spindle structure, avoiding the problem of insufficient support stiffness caused by the ordinary movable tip.
- In the size range of φ6–φ50mm, reinforced concrete hot-rolled with rib rein-forced steel roll crescent slot, such as high rib groove processing applies to PTNM500-CNC series CNC roll milling machine for the crescent. With a high degree of automation, high processing precision, high cutting efficiency machine is easy to operate, safe and reliable, how labor intensity. More suitable for the processing of tungsten carbide roll rings, high speed steel roll and the composite roll can be milled grooves, engraving machine and so on characteristics.
- The machine bed, headstock main parts such as closed frame structure, high rigidity, good earthquake resistance;
- The machine tool guide by using super audio quenching, good precision.
- The high performance CNC system, can automatically cut the different rotating crescent slot, arbitrary angle;
- Can self action any portions of the indexing or spaces, automatic engraving label designation and grade marking (26 English letters and 0-9 digital engraving)
- Beside the standard Vertical milling head for slots (2.2kw - 0-5000rpm), the machine is also equipped with a Special cutting tool, high speed cutting (2.2 kw 2000-10000rpm). Compared with the traditional processing roll crescent slot, high efficiency.
- The quality of the processed roller is high, which can ensure the steel bar reaches the size and precision of the international standard.
Dual purpose, optimised performance.
Popular across the emerging markets, Profimach’s Rib cutting and name marking machines are ideal for fast growing steel companies aiming for higher productivity without comprmising on the world-class ‘quality’.
The solutions combine the rib cutting and name marking operation in a single machine and provide an unmatched competitive edge to the steel roll shops. Ideal for carbide rolls, the machines come with standard name marking device to perform dual operations.
The CNC Rib cutting Machine is used to create Rebar Notches for various sizes of Rebar ranging from 6mm to 50mm. The 4 axes machine is known for its ease of operations, and uses the mechanical process to cut into the rolls. Different types of cutting tools are used to achieve the same.
With almost every large steel brand depending on the Profimach’s rib cutting machines, the solutios have a deep penetration in the market and a formidible reputation for its performance.

Some advantages of the PTNM-500CNC NOTCHING & MARKING TURNING MACHINE for CNC MILL-ROLLS and MILL-RINGS we propose are the following:
• The machine can perform automatically all the international standards and whatever is required in terms of notch skipping and notch enlarging.
• Absolute accuracy for the notch dimensions (rib depth, thickness and angle) and tool positioning is achieved by the special unique direct motor-tool transmission with no belts.
• That’s particularly important when performing tungsten carbide rings and composite rolls. The worker input the diameter of the roller, the rib depth, angle etc. then the CNC will run automatically.
• Tool can move to the next pass automatically; the worker only need input the distance which between the two passes. So, its positioning is a quick, accurate and automatic operation.
• The Y axis and Z axis have zero-point function. The machine can find this zero-point easy. So, in the roll reconditioning operations, the tool can be easily and accurately centered on the worn rib machine can perform automatically all the operations like skipping and enlarging ribs, as well as the change of channel. This means a fantastic reduction in the operator time.
CNC Notching & Marking Machine installed with Siemens
CNC Controller and Siemens Servo Motor, suitable for tungsten carbide roll or high-speed steel roll or high-nickel chromium composited roll or cast-iron roll. It can notch ribs mark the symbol on the roll.
CNC Notching & Marking Machine can be set for following functions:
Function 1: Notching (base function) CNC machine can notch ribs for the deformed steel bar with all standards. CNC machine uses 4 servo motors.
Function 2: Marking (basic function) CNC machine can mark logo, character, drawings etc. on the surface of the roll.
