Abstract

Disclosed is a single-sheet cylindrical cutter. Flat blades and burr guide blades are uniformly distributed on the circumference of a cutter body at intervals, the bur guide blades are provided with left burr guide blade bodies and right burr guide blade bodies, the tooth tips of the burr guide blades are 0.5 mm higher than the flat blades, and the included angle between the front and back portions of the tooth tips of the burr guide blades and the horizontal line is 45 degrees. According to the single-sheet cylindrical cutter, the structure of the burr guide blades is additionally arranged, the processing face is brighter and cleaner for processing of cork materials, cutting is easier, no burrs are generated, the cost for processing and repairing in the later period is reduced, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a woodworking slotting knife. Background technique [0002] The woodworking slotting knife is used to make one or more grooves on the wood. The traditional slotting knife slots the wood through the flat edge of the knife, which will cause burrs on the surface and the tool life is short. Contents of the invention [0003] In order to solve the problem that the existing slotting knife causes burrs on the product surface, the invention provides a single-piece deburring cylindrical knife. [0004] The technical scheme adopted by the present invention to achieve the above object is: a single-piece cylindrical knife, flat blades and hair leading edges are evenly spaced on the circumference of the knife, and a left hair leading edge and a right hair leading edge are arranged on the hair leading edge. [0005] The tip height of the leading edge is 0.5 mm higher than that of the ...
