Additional 5-axis unit

The air-cooled PBA main unit with spindle drive is rated at 63 kW, with a stepless speed range of 0 to 12,000 rpm. Up to a speed of 3,000 rpm, the spindle motor can provide a maximum torque of approx. 150 Nm; or approx. 50 Nm at 12,000 rpm.

Exchangeable chainsaw

The chainsaw, which can be exchanged by means of the HSK 80-E tool holder, has a maximum slot depth of 500 mm and a slot width of 8/12/14 mm (depending on the choice of saw chain). This saw blade's special geometry allows precise production of corners without radii, e.g. on window or door cuts.

Angle unit

For automatic changing into the 5-axis unit. With the ER 40 collet chuck holder, short end mills, spiral drills, dovetail cutters or similar tools can be installed. The max. effective tool length is 160 mm, with a max. diameter of 40 mm.

Travelling machine cabin with integrated airborne dust extraction

The cabin reduces noise emissions during machining and effectively prevents the escape of chips and suspended dust. The machine can be safely entered via two access doors on each long side. The Y traverse path of the unit tower (Z-axis) protruding from the cabin is covered by two aluminium blinds on each side. These automatically adapt to the respective Y position of the tower. The cabin has integrated piping for the suspended dust extraction system for connection to a customer's extraction system. Required extraction capacity approx. 18,000 m³/h with approx. 3,5002.700es are mounted on these which can be used for rough cleaning of the table support strips after machining. In addition, there are pneumatically vertically movable small bulkheads to minimize the openings for different part widths. The cabin dimension is dependent on the equipment and tool selection (e.g. use of deep hole drilling equipment, chain blade with effective length = 500 mm etc.)

Cross-line laser with camera

The machine is equipped with a cross-line laser and camera for manual measurement of the parts. The parts can be easily and conveniently provided with measurement points which then serve as a machining reference.

Automatic laser part measurement type "OBR" for air-cooled spindles

An optoelectronic referencing system (OBR) can be used for automatic determination of the exact part position. It is mounted on the spindle motor of the 5-axis unit and, due to its special sensor technology, is able to precisely measure both raw panels and partially machined panels.

Remote maintenance

The remote maintenance enables a remote display of the screen contents of the control panel computer. This makes it possible, for example, for Hundegger to see the current job or individual part, or for the Hundegger service department to check the machine data or to change the system settings. It is also possible for the customer to see the service employee’s screen. In this way, settings or changes to the part input carried out by Hundegger can be followed by the machine operator. The scope of delivery also includes a portable device with camera function, which enables videos of machine processes to be recorded.

Pneumatically operated part clamps for machining tables

The folding clamps press the part pneumatically onto the table support beams. If necessary, the clamps are swung away and moved down to their parking position. Up to 3 clamps can be installed laterally per table segment. In addition, the raw panel can be held at the end faces with up to 4 clamps. The maximum clamping height for 850 mm high tables is 300 mm.

Panel extraction for parts

The panel extraction system with patented TORNADO channel is fixed to the hall floor on the outlet side after the deflector. The Z-stroke is performed by servo motor. When the part is fed out, chips and sawdust are extracted from the top of the panel.

Pipe channel

The pipe channel runs along the entire travel length of the system. and the airborne dust system of the PBA machine is connected to it. The connection Ø for the customer-side extraction system is 500 mm. The required capacity at the connection of the pipe channel is approx. 18,000 m³/h with approx. 2.700 Pa negative pressure.

Transfer roller conveyor, infeed side

The driven roller conveyor is installed after the infeed-side deflector in front of the machining tables.

Technical data:

•        conveyor length 4,000 mm

•        conveyor width 3,500 mm

•        heavy duty rollers galvanized with Ø 121 mm

Smart Table with zones that can be raised and lowered

The 5 segments can be raised and lowered separately and have their own roller drives. This allows part sections to be exposed and, where possible, machined on the end or front face.

Technical data:

• Conveying length 16,6 m
• Conveyor width 3.500 mm
• Heavy duty rollers galvanized with Ø 121 mm
• Roller spacing approx. 370 mm to 500 mm
• Machining height = 850 mm
• Transport height of the parts = 875 mm

Part supports integrated in Smart Table

40 mm wide wooden supports which can be exchanged via claw clamping jaws and which can be milled off by max. 50 mm.

Transfer roller conveyor, outlet side

The driven roller conveyor is installed after the machining tables in front of the outfeed-side deflector.<br/> Technical data: 

• Track length 4.500 mm
• Conveyor width 3.500 mm
• Heavy duty rollers galvanized with Ø 121 mm
• Roller spacing 368 mm

Flap removal underneath the machining tables

With the flap removal system installed under the machining tables, sawdust is discharged to one side of the processing table. The carriers consist of wooden slats which can be easily exchanged on site. This position contains a drive unit with control. 

Deep hole drilling device

By means of the HSK-80 E tool holder, the deep hole drilling unit can be installed in a 5-axis main unit. Horizontal drilled holes on all 4 sides of the part are possible. With appropriate pre-machining, (e.g. by an end mill), the possible drilling entry angle is max. ± 30°. The maximum drilling depth is 1,250 mm. Deep-hole drills with diameters from 12 to 30 mm can be used. Drilling chips are blown out of the drilled hole by an integrated blow-out device during the drilling process.

Stationary deflectors - electrically operated

The deflectors are mounted laterally on the machining area in extension of the machine zone. They serve as protection against pieces of scrap thrown out in the longitudinal direction of the machine. For the infeed and outfeed of parts, the protective walls are equipped with a bulkhead that can be raised and lowered by servo motor.
