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:
Glass cutting machines
2D cutting machines that orient a glass cutting wheel always tangent to the current position
of the trajectory in the programmed layout.
Specific requirements
• Optimize production by saving labor costs for loading and unloading
• High cutting speed for required lines and shapes
• Minimizes waste material when cutting parts, shows the operator on the breaking table the already cut layout, reprograms the layout keeping track of broken parts during separation
Drilling and polishing centers
3-axis machines with tools and slotters on the spindle for working on edges.
Specific requirements
• Achieves uniform surface smoothing results across the entire perimeter of the shape
• Complex sequence of tools required during machining
Waterjet cutting machines
3- or 5-axis machines for cutting flat glass sheets with high-pressure water and abrasives.
Specific requirements
• 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
Main CNC features
• PC-based solution: a single hardware containing the CNC together with HMI, CAM and Cutting Optimizer, 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 round edges while maintaining a defined tolerance, to reduce mechanical vibrations, reduce machining times and improve finishing results
• High speed machining optimized for tangent cutting wheel
• Volumetric compensation of positioning inaccuracies due to mechanical asymmetries and machine misalignments
• Coordinates and operating origins for rototranslation and mirror machining
• High speed machining available on 5-axis interpolation
• Programming of the position and orientation of the tool tip with the Tool Centre Point (TCP) with bi-rotary heads and different tool orientation
• Support for digital servo interfaces such as EtherCAT and Mechatrolink, but also inexpensive pulse-dir servos can work well
• 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
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 machining preview that the operator can rotate, pan, or zoom in. The cut path is color-coded to quickly understand the extent of the work done.
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 pre-setting, 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 from any graphically selected block. Works with repeats and nested macros.
• Support for suspension of processing, 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
PLC logic environment
• Powerful PLC logic shell compliant with IEC61131 standard
• Extensive application libraries
