SILENT-POWER®

The Silent-Power® spiral knife cutterblock reduces the noise emissions when planing by more than a half. Specially developed tungsten carbide blades with their constant pulling cut, guarantee a tear free planing finish of every wood type. The optimised extraction hood ensures that the noticably shorter chips are effectively extracted and land considerably more compact in the dust bags. This more compact filling of the chip bags, saves you from having to frequently change the bags. Maximum reliability and highest level of planing quality - the innovative new development from Format-4 offers a planing system with knives that have a usable life up to 20 times longer when compared to a conventional HSS-blade system. Damaged blades can be exchanged individually, removed and replaced with a few turns of the hand. The advantages at a glance ...
- Sensationally quiet, noise emissions halved
- Blade life up to 20 times longer
- Four highly precise cutting edges on each knife Click here to get more information

Digi-Drive

The programmable “Digi-Drive” thicknessing table control makes it possible to enter the thicknessing height using the numeric keypad and the thicknessing bed positions itself automatically and precisely. Two intregrated LED displays show the current target and actual values. To optimise production you can save incremental measurements and individual thicknessing table positions.

Outstanding stability and long-lasting precision

4 trapezoidal spindles guarantee exact adjustment precision and ensure maximum thicknessing bed load. Longitudinal guides integrated into the side of the machine chassis absorb the pressure that is put on the outfeed side and ensure that the thicknessing table is guided with an accuracy of a tenth of a millimetre.

Intuitive Format-4 changeover concept

The tried and tested Format-4 operating concept reduces the effort in changing from planing to thicknessing to a minimum. The intuitive table clamping system makes it possible to synchronously lock and open the planing tables with a twist of the hand, industrial springs assist in the opening.

Stability, precision and space saving with the Format-4 planing fence

A masterpiece of stability, precision and space saving design - the innovative parallelogramm Format-4 planing fence system design allows you to be able to position your machine directly next to the workshop wall, without restricting the planing width. The planer fence can be tilted to any position between 90°–45°, the planer fence will always remain flush with the planing table.
