Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing;

[0015] see figure 1 , 2 As shown, a spiral edge reamer includes a handle 1 and a cutter head 2, and the cutter head 2 is provided with a rough reamer 7 and a fine reamer 4 along the axial direction, and the rough reamer 7 is located at the end of the cutter head 2 At the starting end, a processing transition groove 5 is provided between the rough reamer 7 and the fine reamer 4, which is characterized in that: the blades of the rough reamer 7 and the fine reamer 4 are spiral blades 6, and the spiral A chip flute 3 is provided between the cutting edges 6, and a cutting corner 8 is provided at the end of the helical cutting edge 6.

[0016] The chip flute 3 provided between the rough reamer 7 and the helical cutting edge 6 of the fine reamer 4 connects and corresponds at the transition groove 5 .

[0017] The cutting angle 8 is 30-60 degrees.

[0018] Both the rough reamer...

Abstract

The invention relates to a helical-edge reamer. The helical-edge reamer comprises a reamer handle and a reamer head, wherein the reamer head is provided with a roughing reamer and a finishing reamer, the roughing reamer is located at the starting end of the reamer head, and a machining transition groove is formed between the roughing reamer and the finishing reamer; cutting edges of the roughing reamer and the finishing reamer are helical cutting edges, the number of each of the helical cutting edges of the roughing reamer and the finishing reamer is respectively 4-8, cuttings containing grooves are formed between the helical cutting edges, cutting angles are arranged at the end parts of the cuttings containing grooves, and the cutting angles are 30-60 degrees; the cuttings containing grooves which are formed between the helical reamer edges of the roughing reamer and the finishing reamer are correspondingly connected outside the machining transition groove. According to the helical-edge reamer disclosed by the invention, oblique angle cutting is formed due to the helical cutting edges, cuttings can be smoothly removed, and tough material adhering and galling phenomena are avoided, so the surface roughness of the hole wall is reduced, the machining accuracy is increased, and the machining is more smooth during a cutting and machining process.

Description

technical field [0001] The invention relates to the technical field of hole processing, in particular to a spiral blade reamer. Background technique [0002] A reamer is a tool used for finishing and roughing a hole. The existing reamer can complete the roughing and finishing of a hole without changing the tool, which improves the work efficiency. The blade in this invention is a straight-toothed blade, and the straight-toothed blade cannot solve problems such as roughness of the hole forming section and cutting and cracking during processing. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a spiral reamer with stable machining process and high working precision. [0004] Realize the technical scheme of the present invention as follows: [0005] A spiral edge reamer, comprising a handle and a cutter head, the cutter head is provided with a rough reamer and a fine reamer in the axial direction, the rough ...
