Woodworking

A CNC with solid roots

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:

Nesting machines
3- to 5-axis machines dedicated to cutting and decorating pieces of panels for furniture, doors, advertising signs and lightweight structures.

Specific requirements

  • Optimize production by saving labor costs for loading and unloading
  • Reduces processing times to increase productivity
  • Complex sequence of tools required during machining
  • Complex work list and continuous interaction with production supervision management software

Drilling machines
Machines dedicated to drilling, sawing and cutting panels for the construction of furniture and kitchen countertops.

Specific requirements

  • Reduces the time needed to change the aggregate working configuration
  • Workpiece larger than the machine's working area

Lathes
3, 4 or 5-axis machines capable of simultaneously performing turning and milling operations to create columns and table legs.

Specific requirements

  • Turning and sanding, or milling and sanding, in one pass
  • Easy programming directly from the 3D model

Saw blade cutting machines
3-axis cutting panels with oriented saw blade.

Specific requirements

  • Optimize production by saving labor costs for loading and unloading
  • High cutting speed

Machines for the solid wood industry
3- or 5-axis machines that work solid wood to create furniture, chairs, doors, window frames, and wooden tools.

Specific requirements

  • Complex sequence of tools required during machining which also include aggregates, angle tools and blades
  • Reduces overall processing time
  • Avoid collisions with blocks and move them during processing to complete the work cycle
  • High precision and accuracy required for finishing machining
  • The result is a smooth machined surface

Main CNC features

  • PC-based solution: a single hardware containing the CNC together with HMI, CAM, nesting, optimizer and simulator to control the mechanical constraints of the machining, with completely separate and independent resources, to increase reliability and reduce costs
  • Look ahead up to 256 blocks, over 15,000 instructions per second
  • Multi-channel architecture capable of executing several part-programs simultaneously and synchronizing them
  • Standard ISO6983 syntax for complete definition of parametric machining and nesting programming, simplifying the interface with third-party CAD-CAM
  • Up to 96 controlled axes, some of which are dedicated to machining, the remaining ones for moving the piece and blocks
  • Typical Motion Control features available in CNC: gears in position, electronic cams
  • 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
  • Automatic adjustment of the spindle rotation speed according to programming, to maintain a constant speed or maintain a constant amount of material removed during turning
  • High speed machining to chamfer edges while maintaining a defined tolerance, to reduce mechanical vibrations, reduce machining times and improve finishing results
  • High-speed machining optimized for milling on rotating blanks
  • High-speed machining optimized for blade cutting
  • 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 Center Point (TCP) with bi-rotary heads with many tools oriented in different directions and with rotating head and tilting head configuration, both typical of 5-axis woodworking machines
  • Alias axes to work on different physical axes with the same part program
  • Management of auxiliary functions without having to interrupt movement
  • Availability of TCP parameter auto-calibration cycles. The newly obtained parameters can correct the part programs generated by CAM to adapt to reality.
  • Support for many different digital servo interfaces, for controlling EtherCAT and Mechatrolink servos with position or speed reference
  • Feed forward of speed and torque to have a trajectory following error close to 0
  • 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

  • Easy OEM HMI integration using reusable user controls or interface customization provided by ISAC
  • 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

  • Tool life management
  • Tool presetting, wear calculation and online integrity control
  • Automatic and highly efficient tool change management
  • Lathe tool size compensation at virtual tool tip or radius compensation
  • Advanced milling tool radius compensation with a large geometric look-ahead to prevent damage to workpieces
  • Safely withdraw the tool from the material in the current tool direction. Machining with the spindle, tools, and blades oriented in space.

PLC logic environment

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