Stone working

Choose a CNC with rock-solid experience in cutting and processing stone

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

All our experience with these machines:

Engraving machines
3-axis machines that use spindles for stone carving and engraving to create bas-reliefs, bathtubs.

Specific requirements

  • Easy operator approach
  • Very long execution of the part-program that must be interrupted and resumed
  • Complex sequence of tools required during machining
  • Bas-relief copying functionality

Polishing machines
3-axis machines with tools and slotters on the spindle for smoothing the surface and edges of the sheet.

Specific requirements

  • To have the same mirror surface results at different points of the shape

Bridge cutting machines
4- or 5-axis machines for cutting and milling stone or composite material slabs to create tiles, kitchen or bathroom countertops, statues, building frames, and decorations.

Specific requirements

  • Management of manual cutting with oriented tools
  • Easy integrated definition of the machining that does not require programming skills, directly from the drawing
  • Ability to work with disc, milling and boring tools mounted on the same workhead but with different orientations
  • Very long execution of the part-program that must be interrupted and resumed
  • Using less material to cut all shapes, avoiding surface defects

Engraving machines
3- or 5-axis machines for cutting stone slabs or composite materials with high-pressure water and abrasives.

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
  • Exploitation of cutting times with cutting quality
  • Hydro-jet engraving

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 complete definition of parametric machining and nesting programming, simplifying 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 chamfer 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 workpiece damage, extend machine life, and increase machining quality
  • Coordinates and operating origins for rototranslation and mirror machining
  • High speed machining available on 5-axis interpolation
  • Programming the position and orientation of the tool tip with the Tool Centre Point (TCP) with bi-rotary heads and different tool orientations
  • Support for many different digital servo interfaces for controlling servos with position or velocity reference
  • OPC UA server for connection to 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

HMI

  • Custom operator panel created using a specific development tool. Alternatively, the OEM can integrate CAM into the HMI using reusable user controls.
  • High-definition interactive preview that the operator can rotate, pan, or zoom in on. The cut path is color-coded to quickly determine the extent of the work done.
  • Simulation environment available to check mechanical constraints and collision before running the part-program

Tools

  • Statistical compensation for tool wear in radius and length. Dynamic adjustments to keep the tool operating at constant torque (dynamic wear compensation).
  • Tool life management
  • Tool presetting, wear calculation and online integrity control
  • Automatic and highly efficient tool change management

Work aids

  • Resumes processing after an unexpected shutdown from the last executed block or any graphically selected block. Works with repeats and nested macros.
  • Support for suspension of work, manual control and maintenance and resumption from the trajectory position
  • After resuming, the change in tool length is automatically compensated
  • Safely withdraw the tool from the material in the current arbitrary direction of the tool
  • Waterjet cutting process parameter database integrated within the part program. CAM can select parameters based on the material, thickness, and cut quality required for specific sides. The operator can choose a different selection.
  • Parameter Database Editor
  • Integrated CAD-CAM component dedicated to cutting with disk and boring, with connected camera to take photographs of the sheet, identify any defects and position the imported shapes to perform the cutting avoiding them

PLC logic environment

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