Description

Thin-wall end mill special for foam wave-absorbing material

Technical Field

The utility model relates to the technical field of foam cutting tools, in particular to a special thin-wall end mill for foam wave-absorbing materials.

Background

Milling tools are rotary tools for milling machining having one or more cutter teeth. When in operation, each cutter tooth cuts off the allowance of the workpiece intermittently in sequence. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces, cutting workpieces, etc. on milling machines.

Foam has a series of characteristics of elasticity, light weight, quick pressure-sensitive fixation, convenient use, free bending, ultra-thin volume, reliable performance and the like, is increasingly widely applied to aerospace manufacturing industry, but has poorer cutting processing performance, and particularly when the thickness of a 3D foam composite material product is only 2mm, the risk of product falling and scrapping is easy to occur, and finally, the existing 3D composite material processing yield is low, the appearance quality of the product is greatly influenced, and the high-quality and high-efficiency milling processing requirement of the 3D composite material part is difficult to meet.

Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be described in detail below. The described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, based on the examples herein, which are within the scope of the utility model as defined by the claims, will be within the scope of the utility model as defined by the claims.

The utility model is described in further detail below with reference to the embodiments of the drawings.

As shown in fig. 1, the embodiment provides a special thin-wall end mill for foam wave-absorbing materials, which comprises a cutter body and a cutter handle; the cutter body is cylindrical; the knife handle is cylindrical; two rows of cutting edges are arranged on the cutter body, and the inclination angle of the cutting edges is 10 degrees.

In this embodiment, the cutter body and the cutter handle are integrally formed.

In this embodiment, the formed connection part of the cutter body and the cutter handle has a certain radian, and the formed angle is trimmed to be 1 °.

In this embodiment, the surface roughness of the shank is not greater than 0.8mm.

In this embodiment, the surface roughness of the cutter body is not more than 1.6mm.

In this embodiment, this cutter utilizes to design the angle of cutter body cutting edge to 10, through improving the distance between traditional straight bar type cutter clearance cutting edge and the handle of a knife, has solved because the thin wall that straight bar type cutter led to is cut excessively, has guaranteed the qualification rate of product, compares with traditional combination cutter, and the special thin wall end mill of foam wave-absorbing material structure that this embodiment provided is complete, and the parameter setting is reasonable, and the cutter life-span is steady, and cutting force is steady, and cutting quality is good, defects such as drop that the thin wall of improvement foam wave-absorbing material part thin wall processing that can be fine cut excessively.
