Metal processing

A solution that does not rust

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 make small sculpted pieces with mirror finish requirements.

Milling machines, boring machines, drilling machines
Orientation tools relative to the blank for 3 to 5 axis machines.

Turning machines
3-axis machines with blank rotation and tools mounted on turrets.

Transfer machines
Multi-station machines that each perform a specific task in the process sequence.

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, simplify the production of real-world programs and reduce costs
• Look ahead up to 256 blocks, over 15,000 instructions per second
• Multichannel architecture capable of executing several part-programs simultaneously and synchronizing them
• Standard ISO6983 syntax for the complete definition of machining and parametric nesting programming, which simplifies the interface with third-party CAD-CAM
• Up to 96 controlled axes, some of which are dedicated to machining, the rest for the movement of the piece and blocks
• Gantry axes
• Typical Motion Control features available in the CNC: gears in position, electronic cams
• 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 the programming, to keep the speed constant or keep the amount of material removed during turning constant
• Thread on turning
• Tapping on milling
• High-speed machining to smooth edges while maintaining a defined tolerance, to reduce mechanical vibrations, reduce machining times and improve finishing results
• Superfinishing machining algorithms
• 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 configurations of bi-rotary heads, tilting tables and 5-axis milling-lathe
• Availability of self-calibration cycles of TCP parameters. The recently obtained parameters can correct the part-programs generated by CAM to adapt to reality
• Support for many different digital servo interfaces for position or speed referenced servo control
• 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

HMI

• 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 path already
cut is identified using different colors to quickly understand the amount of work done
• Simulation environment available to check mechanical constraints and collision before executing the part-program, evaluate machining times and optimize work cycles

Tools

• Tool life management
• Tool presetting, wear calculation and online integrity check
• High efficiency and automatic tool change management
• Compensation of the lathe tool size at the virtual tool tip or radius compensation
• Advanced milling tool radius compensation with extensive geometric look ahead to prevent damage to workpieces
• Quick and automatic tool change with linear, rotating and tray tool magazine
• Random tool change with management of tool families

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
• Safe withdrawal of the tool from the material in the current arbitrary direction of the Robotic module tool
• The CNC can control the kinematics of robots such as DELTA, SCARA, PUMA
• The OEM can create additional robot kinematics
• The trajectory of picking up, loading and unloading of the piece performed by the robot can be controlled by CAM itself which knows in an appropriate way the geometry of the raw piece and of the finished piece

PLC logic environment

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