PONTEC CNC Multi-Functional Bridge

The multifunctional computer numerical control (CNC) bridge is designed for the machining of wood panels in an offsite construction factory. 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 labor 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 of this is a fully automatic process with maximum accuracy.

The concept of the Pontec machine is modular, variable, and fully corresponds to the requirements of the proposed technology. The plant is already in its basic configuration equipped with a milling spindle with liquid cooling, a C-axis for the use of aggregates, and 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 fiber 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.

Determination
