Mechanical Structure

01.1 – A moving bridge type machine with a fixed worktable divided in two vacuum independent zones. During machine operation the work piece is steadily clamped on one of the working tables while the operator can unload and load on the other for non-stop manufacturing.

The machine frame is constructed in engineered steel with supporting ribs and gussets. Dimensions and structural components have been studied according to dynamic principles to guarantee rigidity and torsional strength. All components are heat treat stabilized.

02.2 ‑ Electric box equipped with safety mechanical devices with extractable key, consisting of:

Lubricating System

03.1 – The machine is fitted with a centralized lubrication system by oil, complete with pump, pressure control to guarantee a regular and constant lubrication by pipes and valves, with flow of lubricating oil on the movable parts such as linear motion guides and bearings, guide rails, rack and pinion, ball screws.

03.2 – Self-diagnosis and alarm device in case of oil fault of the above-mentioned lubrication system, with alarm display on the main control panel.

03.3 ‑ Manual greasing points are clearly visible on all sliding parts of occasional and marginal use, requiring monthly or periodical lubrication.

Numerical Control

05.1.a – Fanuc 180i MB5 full digital, LCD 10.4″ TFT color VGA, for high efficiency and performances, equipped with main following characteristics, expressly chosen for the best versatility and use in the specific field of woodworking consisting of:

           – Main control CNC 32 bit
           –  Integrated PC with windows 2000
           – 5 axes controlled simultaneously
           – Least input increment 1 micron
           – Helical interpolation for spiral machining
           – Part program storage on hard drive of 20 GD
           – Program input from the keyboard or floppy disc and/or RS 232
           – Exponential type acceleration and deceleration on each axis, settable by   parameters
           – Tool offset and tool length compensation
           – Backlash compensation
           – Self-diagnosis and alarm history display
           – Acceleration/deceleration axis, “linear” type
           – Eventual additional options such as background editing, memory expansion, robot interface, etc.
           – 600 blocks look ahead

07.2 – Jog pendant, and software for Fanuc 180i

Axis Control

06.1.a ‑ A.C., brush less servomotors, with integrated pulse encoder.

06.2 – The X, Y and Z axes are coupled directly to a gearbox with rack and pinion with inclined teeth. The gearbox is mounted on preloaded guides to compensate automatically any backlashes, through an elastic mechanism, for all the cycle of life of the machine. The ball screws, by ball nuts, as long as the rack and pinion, convert the rotary movement of each servomotor into linear movements, which interpolated by CNC, accurately perform the selected program.

06.3 ‑ The maximum positioning speed is 84 meters/min. (3,307”) for the X, 84 meters/min. (3,307”) for Y-axis and 40 meters/min. (1,575”) for Z-axis, achieving remarkable time saving.

Operation Panel

07.1 ‑ The Control Panel fitted on remote pedestal, movable and orientable in the most accessible position or in cabinet attached to the moving bridge and is equipped as follows:

Color LCD 10.4” which enables to visualize absolute positions, parameters and memory, diagnosis, alarms and all necessary functions for information and editing

• Alphanumeric keyboard
• On/off switch for vacuum pump
• Air alarm led
• Electric/electronic alarm led
• Lubrication alarm ledFeed rate switch (FEED RATE)
• Step button (SBK)
• Reset button
• Mode switch (MODE)
• Cycle start button
• Cycle hold button
• Selector for step movement of axes with 0.01-0.1-1 mm. scale
• Emergency stop button

Vacuum Clamping System

09.1‑ 2 Pieces, Becker KVT 100, 5 HP, 100 CMH.

Table Specification

10.1. – The work table is an 3,640 mm (143”) x 2,140 mm (84.2”), divided in two independent suction areas. During the work cycle the operator unloads and loads parts on one side of the machine table, while parts are being machined on the other side of the machine table. A safety wall is provided for separating the two work zones. The machine bridge will not enter the loading station until the operator is clear of the area.

10.2 ‑ Phenolic table surface has 10 mm grooved matrix on 30 mm centers with vacuum access holes every 150 mm for vacuum distribution. The table is complete with lateral references for rapid positioning of jigs and clamping.

Spindle

12.1- The machine is equipped with one motor of 10 kW, 13 hp, up to 22,000 rpm, able to supply the whole nominal power starting from 10,000 rpm. In this spindle the rotor is equipped with 4 angular ceramic ball bearings on the frontal couple, long life lubricated, air cooled and with tool holder type HSK 63 F double lock safety mechanic arrest, hose cleaning device, aligning sensors for operator safety.

12.2 ‑ On the above-mentioned spindle, it is possible to use tool holders type HSK 63 F with collet chucks available to 25 mm. Such collet chucks guarantee near perfect centering of the tool and allow tool dimension as follows: maximum length 100 mm and maximum weight of 3 Kg.

Extra Specifications

14.1 – Refrigerator unit, mounted on the outside shoulder of the machine, fit for cooling the spindle by forced liquid, in order to keep the temperature between a range of 24°C and 27°, especially during heavy Routing tasks.

14.2 – Z axis pneumatic balancing system.

14.3 – Dust package, the machine will be fitted with bellows on the two X axis rack & pinions and linear rails assembles, bellows will be fitted on the Y axis rack & pinion and the linear rails assembles, metal tape protection will be fitted on the Z axis linear rails. The electrical cabinet and all electrical boxes will be dust proof and all connections will be sealed for dust.
