Description:

The large cast iron infeed bed is quick to adjust and lock in place, with a clear setting scale. The bridge guard has simple controls to set the height over the cutters and the gap the the side fence. The side fence can be positioned anywhere across the cutter block, useful for getting even wear on the cutters when working mainly with narrower materials. The fence can also be tilted back to 45 degrees.

One of the main design improvements on this model, over previous versions, is the quick and easy method to change over from planing to thicknessing.  No need to remove the side fence, just 2 locks to undo and then both beds lift in a parallel motion and lock out when fully raised. Next the dust collection hood swings up and over, latches into place, and you are ready to go.

Setting the thicknessing depth is done by rotating the cast iron handwheel (1 rotation = 2mm) and reading from the mechanical digital display, accurate to 1/10th of a millimetre. A position lock is fitted which prevents any movement.

The drive rollers can be disengaged when planing to save wear and tear on the mechanism.

At the heart of the machine is a spiral cutter block with 4 rows of spur cutters, arranged so that they cut in a shearing action, rather than straight. This type of cutter block is more expensive than a conventional set up but does offer several advantages. The more use the machine gets – the more these advantages pay off.

Advantages of spiral cutters over conventional knives:

Shearing Cut = Better finish. Expect a smoother finish in softwood, hardwood and difficult grain.
Low Sound Levels = Less noise by up to 50%. Each blade is moving less air and taking a smaller cut.
More Knives = Reduced energy consumption. Each cut uses less energy, overall saving can be 30%.
TC (Tungsten carbide) Cutters = longer cutter life, up to 10 times compared to HSS. Each cutter can be rotated when worn.
Less Maintenance = Quick and easy to change out 1 or 2 cutters after a chip.

It is essential to use dust extraction with a planer thicknesser. The extractor removes all the dust and chips which will otherwise build up, causing a blockage and eventually damage to the machine. Using an extractor also increases the life of the cutters.
