Metal sheet cutting

State-of-the-art technology used in cutting machines.

Costantino is a powerful and flexible CNC that allows you to obtain the maximum result with the minimum effort for all types of applications.
Costantino CNC is the ideal solution for both new machines and retrofits.
The machines equipped with Costantino CNC are able to satisfy all Industry 4.0 requirements.

All our experience with these machines:

3 to 5 axis machines to cut with high pressure water and abrasive, directing the jet to create shaped edges.

Specific requirements

  • Constant control of the distance between nozzle and material
  • Very long execution of the part-program which must be interrupted and resumed on the last part of the cutting path
  • Use of cutting times with cut quality

Plasma & Oxy
3 to 5 axis machines with plasma cutting or flame torch, or a combination of both, orienting the cutting direction with the bevel head to create shaped edges.

Specific requirements

  • Constant control of the distance between the torch and the material
  • Cutting progress as constant as possible
  • Applying the appropriate parameters to the cutting technology to achieve the best cutting quality
  • Use of high definition sources

2D cutting machines with CO2 or Fiber laser cutting.

Specific requirements

  • High-speed cutting capability due to high power concentration, especially for thin materials
  • Constant control of the distance between the torch and the material
  • Continuous interaction with the supervisor and production management software
  • Applying the appropriate parameters to the cutting technology to achieve the best cutting quality
  • Cutting on the fly

Main CNC features

  • PC-based solution: a single hardware containing the CNC together with HMI and CAM with completely separate and independent resources, to increase reliability and reduce costs
  • Look ahead up to 256 blocks, over 15,000 instructions per second
  • Standard ISO6983 syntax for the complete definition of machining and parametric nesting programming, which simplifies the interface with third-party CAD-CAM
  • Gantry axes
  • Controlled jerk movements for all axes involved in the movement and separately for the tool tip, to avoid mechanical stress and obtain the best finishing surface
  • High-speed machining to smooth edges while maintaining a defined tolerance, to reduce mechanical vibrations, reduce machining times and improve finishing results
  • Volumetric compensation of positioning inaccuracies due to mechanical asymmetries and machine misalignments
  • Vibration suppression algorithms to prevent damage to parts, extend machine life and increase machining quality
  • Coordinates and origins of operation for roto-translation and mirror processing
  • High-speed machining available on 5-axis interpolation
  • Programming the position and orientation of the tool tip with the Tool Center Point (TCP) applied to chamfer heads
  • Appropriate management of heads with compensation
  • Availability of self-calibration cycles of TCP parameters. The recently obtained parameters can correct the part-programs generated by CAM to adapt to reality
  • Real feed rate applied to the trajectory, including orientation changes for compensated heads
  • Management of auxiliary functions without the need to interrupt the movement
  • Path of the trajectory in the front and rear directions (RETRACE)
  • Support of many different digital servo interfaces for position or speed referenced servo control; even pulse-dir servos or stepper motor can be used to the fullest
  • Speed and torque feed forward to have a trajectory following error close to 0
  • OPC UA server for connection with MES
  • Remote I / O connected with EtherCAT fieldbus to allow the exchange of thousands of I / O signals
  • IO-Link interface gateway
  • Safety integrated with FSoE


  • Easy OEM HMI integration using reusable user controls or interface customization provided by ISAC
  • High definition interactive machining preview that the operator can rotate, pan or zoom. The already cut path is identified using different colors to quickly understand the amount of work done

Work aids

  • Management of the life of consumables
  • Resumption of machining after an unexpected shutdown from the last executed block or from any graphically selected block. Works with repeats and nested macros
  • Support for suspension of machining, manual control and maintenance and resumption from the position in the trajectory or outside the trajectory with automatic intersection of the trajectory
  • Control of the distance between the torch and the extremely reactive material thanks to a different feedback sensor able to maintain a tolerance of 1/10 mm even with chamfer heads
  • Dynamic TCP to compensate for the deflection of the water jet
  • Database of the cutting process parameters integrated within the part-program. CAM can select parameters based on the material, thickness and cut quality required on specific sides. The operator can choose a different selection
  • Parameter database editor
  • Jump movements between the shapes to perform the cut
  • Laser power output for PWM adjustment to the current dynamics
  • Starting and stopping cutting without interrupting the movement (On-the-fly cutting).

PLC logic environment

  • Powerful PLC logic shell compliant with IEC61131 standard
  • Extensive application libraries
