Chipping and rounding of the cutting edge of finger joint cutters lead to tremendous losses in machine run time, high grinding costs and excessive spending on new tooling.
The cutting edge is often a solid single layered material.At Kanefusa we have developed a multi-structured material that clearly outperforms ordinary tooling.
The multi-structure takes into account that the top and bottom finger are exposed to different forces and wear. The top of the cutter is made of a highly abrasion resistant High Speed Steel (HSS), which slows down the rounding process and minimizes the chipping of the cutting edge.
The bottom is built from hard but flexible steel to reduce breakage of the fingers due to excessive cutting forces. This structure is built on an alloy steel substrate with a high shock resistance.
TAF-C finger jointing knives (inserts) are used to cut softwood in the production of engineered wood with a length of 15/15, 15/16.5, 20/20 and 20/22 mm.
- 50% longer tool life than regular HP-treated finger joint cutters lead to better machine utilization and less grinds per year
- Less stock removal during grinding relates to a faster grinding and a longer use life of the finger joint cutter
- Because the cutting edge stays sharp, the knife cuts cleaner, which relates to a truer cut profile
