Pontec

CNC multifunctional bridge

The multifunctional CNC-controlled bridge is designed for machining of panels of wooden buildings. The bridge works in combination with WING butterfly and transfer tables and allows work on both sides of the panels. It brings maximum productivity, sustainable quality and labour efficiency. The individual working units do the stapling of board sheets to the frame, formatting to the exact size, milling and drilling of all required construction holes. All this in a fully automatic process and with maximum accuracy.

The concept of the Pontec machine is modular, variable, fully corresponding to the requirements of the proposed technology. The plant is already in its basic configuration equipped with a milling spindle with liquid cooling, with a C-axis for the use of aggregates, a rotary tools changer magazine for 8 tools. The second unit is a Bea stapler. The machine can be extended with another milling unit with an aggregate saw unit or another stapler (nailer).

The device is supplied with an integrated extractor also suitable for gypsum fibre boards.
 

The robust construction corresponds to industrial use. Travel in the X-axis is by means of two synchronized servomotors with nylon belts. The Y-axis is guided in precise linear bearings with a rack and pinion drive. The milling unit is driven in the Z-axis by a servomotor with a ball screw, the stapler by a pneumatic piston.

The whole device is mounted as a part of an individually designed manufacturing line. Protective devices prevent collisions when entering the work area and stopping the machine when moving it.
