Triple-sided drilling machine for use in process lines WPT-300

The WPT-300 drilling machine has been designed to work in automated machining lines, which is reflected by its design allowing the workpieces to pass through the machine as they are processed. It can also operate as a free-standing unit. The drilling machine is intended for making openings for pegs in wood, particle boards and wood-derived materials.

The drilling machine’s frame comprises two gates joined together with two vertical beams. The bottom beam carries the vertical units installed on linear bearings and the right-hand horizontal unit. The top beam supports the clamping mechanisms.

The left-hand horizontal unit is permanently fixed to one of the gates. Each horizontal drilling unit comprises a body, a head, spindles installed using ball bearings, a flexible coupling and two motors.

The vertical drilling unit is equipped with two independent sliding motors with rotary heads. Drills are installed in spindle mounts. The spindles use rolling bearings and are powered with electric motors via flexible couplings. The feed of the units is controlled using pneumatic actuators.

The drilling units with heads are installed on two guides, which allows for positioning them at the desired distance from one another. The feeders and the workpiece clamping system are installed together with the side units. After processing, the workpieces are transported out of the machine using a belt conveyor.
