Embodiment Construction

[0009] Depend on figure 1 As we know, the six-edge spiral surface finishing tool is composed of a clamping part 1, a deep cutting edge part 2, an arc serrated blade part 3 and a tapered blade part 4. The clamping part 1 is longer than the common one, and the deep blade is A circular arc surface is added to the front end of the mouth part 2 . The circular-arc sawtooth blade part 3 is the rear part of the knife tip, and is in the shape of six-edged circular-arc spiral serrations. The tip of the tapered blade portion 4 is conical, and the blade is a high-density helical cutting edge with a shallow cutting edge and a thinner diameter.

[0010] The structure of the present invention uses the six-blade machining of the middle end mill type when machining general workpiece burrs and requires fast machining speed. It has the deepest cutting edge and the highest cutting efficiency in the whole tool. When processing curved surfaces and planes that are difficult to process, use arc bla...

Abstract

The invention discloses a spiral-type surface finishing and trimming cutter which is composed of a clamping portion, a deep cutting edge portion, a circular-arc sawtooth blade portion and a conical blade portion. The clamping portion is longer than a common one, and a circular arc face is additionally arranged at the front end of the deep cutting edge portion. The spiral-type surface finishing and trimming cutter is characterized in that the circular-arc sawtooth blade portion is the rear portion of a cutter point and is in the shape of a six-blade circular-arc-shaped spiral sawtooth. Compared with the prior art, the spiral-type surface finishing and trimming cutter has the advantages that cutting edge shape and cutting edge angle are reasonably optimized for bringing convenience to a milling cutter to cut a plate, and production efficiency is improved; strength of the milling cutter is improved, so that service life of the milling cutter is prolonged, and potential safety hazards in operation are reduced.

Description

technical field [0001] The invention belongs to automatic equipment for deburring special-shaped aluminum castings such as automobile and motorcycle wheel hubs and engines, and in particular relates to a spiral surface finishing and trimming tool. Background technique [0002] Edge trimming machine is a mechanical device for processing and trimming the rough edges of particleboard, fiberboard and other boards in woodworking or other board production, and trims the boards into various curved shapes. The milling cutter is a part that directly acts on the plate on the trimming machine. Due to its structure, the cutting is frustrating and not smooth when used, and its strength is weakened after long-term use, and it is easy to break, which seriously threatens the operation safety. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a spiral surface finishing and trimming tool, which is improved from the origi...
