Abstract

A finger joint cutter is provided. There are four or more teeth on one single cutter, and the teeth are set on both sides of the cutter body in staggered arrangement, so the structure stability is ensured and the interchangeability requirement for combination using is met at the same time. According to requirements of practical production and cutter structure, the finger joint cutter can be classified into four types, which are integral double-slots finger joint cutter, integral edge-slot finger joint cutter, double-slots finger joint cutter with replaceable blade and edge-slot finger joint cutter with replaceable blade. When teeth number required by work piece is odd and the edge cutter is needed, the integral edge-slot finger joint cutter and the edge-slot finger joint cutter with replaceable blade are set at the end of cutter shaft and used with the slot cutter. The blade constructions of the double-slots finger joint cutter with replaceable blade and the edge-slot finger joint cutter with replaceable blade widen the choice of blade materials.
