A difference from the traditional design of thicknessers are the new helical cutter heads that’s now standard in this model. The important advantage of a spiral cutter head is its shearing contact with the work-piece rather than the very loud chopping effect produced by a traditional HSS blade cutter heads. This translates into a much smoother cut with less chipping and tear out of the work-piece as well as significantly much quieter operation.
The Hafco T-20S thicknesser with “Spiral Cutter Head and Carbide Inserts” is a heavy duty machine with very substantial cast iron body and heavy gauge sheet steel base. The cast iron thicknessing table, which has a polished surface for reduced vibration and improved quality of cut, is supported on solid pillars at each corner and has extension rollers both front and back for improved timber support.
Steel rollers with ribbing ensure positive drive on the timber through the machine at a rate of 16 or 20 fpm via two speed gearbox, the feed roller pressure can be adjusted with the four adjusters on the top of the machine. The depth of cut is set by means of the cranked handle on the side using the setting scale positioned on the in-feed side or digital readout display. Power is provided by a 3750W / 5hp 415V induction motor, housed within the base and transmitting power to the cutter block via a twin pulley vee belt drive system.
Spiral cutter heads have now revolutionised wood work planers and thinckners! Offering reduced chatter and tear-out in most timbers. This head has 4 x spirals and comes pre-loaded with a total of 92 fine grain tungsten carbide inserts, which have four cutting edges that can be indexed to offer a new cutting edge in seconds, and do not require a blade setting jig. The general consensus from end users state that when used correctly the inserts can last anywhere from three to five times longer than any standard HSS knives, so if you multiply this by four cutting edges you can achieve 12 to 20 times the normal blade life of a HSS blade set.
