Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as Figure 1-2 As shown, a drilling and chamfering synthesis tool includes a head 5 and a shank 1, a conical part 4 and a cylindrical part 3 are arranged between the head 5 and the shank 1, and the conical part 4 and the head 5 are connected, the cylindrical part 3 is connected with the handle 1, a double helical groove 6 with a helix angle is symmetrically opened on the head 5, and a V-shaped flute 7 is opened on the cylindrical part 3, and the V-shaped flute 7 is connected continuously with the double helical groove 6.

[0029] Such as Figure 1-2 As shown, a drilling and chamfering synthesis tool, the shank 1 is one of triangular shank, hexagonal shank or round shank; the hexagonal shank is a quick-change structure, and there is an R on the hexagonal prism in the middle of the hexagonal shank. Groove 8, the radius of R groove 8 is 1.5~4.5mm, and the radius...

Abstract

The invention discloses a drilling and chamfering synthesis tool and a manufacturing method thereof, belongs to the technical field of hardware tool manufacturing, and is novel in structure and clear in working principle. A drill bit part can be used for general drilling; a conical surface part can be used for hole port chamfering; a cylinder part also can be used for counter bore machining; the machining steps can be performed smoothly; the machining procedures are reduced; the machining cost is saved; and the machining efficiency is improved; the chamfering is excellent in centering and high in precision and smoothness; as a V-shaped chip discharge groove is formed in a cylinder surface, and is communicated with a double-spiral groove at the head part, the cutting is quicker and lighter in the drilling process, the chip removal is more smooth, a lot of cutting head is reduced in the machining process, the cutter service life is prolonged, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hardware tool manufacturing, and relates to a drilling and chamfering synthetic tool and a manufacturing method thereof. Background technique [0002] During the drilling process of metal parts, the rough machining, finishing machining, chamfering and counterbore machining of holes are all completed through multiple processing procedures, each of which requires the use of matching processing tools. On the one hand, Chen Ben Increased; on the other hand, in the process of processing, the processing tool needs to be clamped multiple times, and the positioning accuracy is greatly reduced after multiple clamping, the machining accuracy of the hole cannot be guaranteed, and the processing efficiency is also reduced. At present, the drill bits used in the drilling process can achieve a dimensional tolerance grade of IT13~IT11, and a surface roughness value of Ra50~12.5μm. Therefore, the drilling process has th...
