Stone processing

Choose a CNC with rock solid experience in stone cutting and machining

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:

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

Specific requirements

  • Easy operator approach
  • Very long execution of the part-program which must be interrupted and resumed
  • Complex sequence of tools needed during machining
  • Copying functionality of the bas-reliefs

Polishing machines
3-axis machines with tools and slotting machines on the spindle to smooth the surface and edges of the slab.

Specific requirements

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

Bridge cutting machines
4 or 5 axis machines for cutting and milling stone or composite material slabs for making tiles, kitchen or bathroom tops, 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 work head but with different orientations
  • Very long execution of the part-program which must be interrupted and resumed
  • Use of 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
  • Use of cutting times with cut 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 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 of the position and orientation of the tool tip with the Tool Center Point (TCP) with bi-rotary heads and different tool orientation
  • Support for many different digital servo interfaces for position or speed referenced servo control
  • 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


  • 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 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
  • Simulation environment available to check mechanical constraints and collision before running the part-program


  • Statistical compensation of tool wear in radius and length. Dynamic adjustments to make the tool work at constant torque (dynamic wear compensation)
  • Tool life management
  • Tool presetting, wear calculation and online integrity check
  • High efficiency and automatic tool change management

Work aids

  • 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 processing, manual control and maintenance and recovery from the trajectory position
  • After resuming, the change in tool length is automatically compensated for
  • Tool withdrawal from material safely in the current arbitrary tool direction
  • Database of the parameters of the waterjet cutting process 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
  • Integrated CAD-CAM component dedicated to cutting with disc and boring, with camera connected to take photographs of the plate, identify any defects and position the imported shapes to make the cut avoiding them

PLC logic environment

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