Unix

The UNIX compact two-unit CNC working centre reflects the latest development in window manufacturing. It is optimized for the efficient manufacturing of window components and other specific products such as arches, panel doors, etc. encountered in the daily work schedule.

The UNIX machine has been designed for heavy milling work in a dusty environment. The heavy robust concrete-filled base helps to absorb vibration resulting from the machining of large sections of different wood types and associated materials. The two-spindle concept includes all the benefits of a strong, firm 3-axis working unit required for solid wood processing and a flexible 5-axis unit for drilling and milling operations. In addition, it provides a new capability for 3D operations frequently required by conservatory manufacturers.

Working units:

• The main 16kW electrically driven spindle which has a ceramic bearing and is liquid cooled is equipped with the HSK 63E clamping system which carries 200mm long spindles with tooling. The C axis works with a woodchip removal deflector which enhances the efficiency of the dust collection plant.
   
• The flexi 5-axis 7kW electrically driven spindle which has an harmonic drive gearbox and torque motors in the A and C axis is again liquid cooled. Drilling and milling tools are attached on chucks with HSK 63F clamping system. The unit can also use specialised tools, for example: window rebate, 3D operations and a saw blade of up to 400mm.

The linear tool changer with 21 positions can store about 40 profiles, sufficient for everyday work. The tool manager provides a stable position in the rack for frequently used tools. Tools for occasional use are placed in the rack when necessary. The side tool changer is used for a planing head for 3D operation and saw blade with a diameter of 400mm. A special tool changer for the flexible 5-axis unit is situated on the main arm to facilitate quick tool exchange.

Automatic consoles with an innovative clamping system facilitate easier loading and unloading of the timber. The operator remains in one place and the consoles are filled in accordance with the work list. A line laser shows the start position of the timbers to the operator who inserts the two pieces to be clamped in the central carriage. After cross and longitudinal profiling and drilling operations, the central clamp moves the pieces over to the side clamps for last side profiling. On exit from the machining, the pieces can be easily removed. Central carriages also transport the pieces clamped together back to the operator enhancing the ergonomic operation of the machine.

The manual clamping consoles remain in a standby position during in-line manufacturing. They are used for specialised work, for example: arches, door leaves or stair components etc.

The UNIX machine is powered by the highly regarded BECKHOFF PC industrial control system. The industrial PC uses Ethercat connected servo-drive systems and input-output modules controlled by specialised software to create a well-harmonised machine control system. The administration of working batches begins in WinCreator as a simulated workflow, and is then sent to the machine and processed by the machine control system.  The WinCreator interface is open to any branch-related software. The user-friendly intuitive environment makes machine control, tool set-up, tenoning, profiling and macro-processing straightforward, including new modules for arch pieces and CAD/CAM for panel work processing.
