Description

Milling cutter

The application is to be August in 2014 7 according to the applying date, Application No. 201410386585.5, invention and created name The divisional application proposed by the original application of milling cutter.

Technical field

The present invention relates to a kind of process tool for being applied to industry cutting, more particularly to a kind of milling cutter, it is applicable to process The cutting of metal, engineering plastics and fibrous composite, to improve raising processing efficiency.

Background technology

Cutter is the instrument for being used for machining in machine-building, also known as cutting element.Because most of cutter is Machine, it is substantially all for cutting metal material, so " cutter " one word is typically just interpreted as metal cutting tool.But material Scientific development, various materials have also been able to extensive use in the production and processing of product, such as：Engineering plastics and carbon fiber are answered Condensation material etc. (CN203401118U).Cutter can be divided into by the form of workpiece machining surface：Process cutter, the hole of various outer surfaces Process tool, threading tool, gear cutting tool and cutting off tool etc. are several.

Component of the Milling Machining in field of machining is becoming more and more important, progressively takes to a certain extent For other processing modes such as car, brills.Due to the extensive diversity of Milling Machining, except metal materials such as traditional steel and cast iron Outside, increasing novel metal/nonmetallic materials are also progressively included into the row of the machined material of Milling Machining, among these not only Various metal alloys including aluminium-containing alloy, the various resin materials also including high-grade engineering plastics, and it is various Carbon fiber metal composite plate including carbon fibre composite.

In Milling Process, the most it is difficult to only cutter is realized simultaneously to two or more dissimilar material properties with one It is cut material and carries out Continuous maching.Such as：The pure nickel of the vermicular cast iron of string milling high rigidity and easily cold welding, the former needs To overcome rigidity, the latter needs sharp cutting edge to bend and stretch intensity to overcome, avoids cold welding the blunt cutting edge of circle.And for example：String milling Silumin and cermet, the former needs big relief angle cutting edge high-speed cutting to reduce processing deformation, and the latter needs big anterior angle Low speed is processed to ensure surface to be machined integrality.

Such processing request causes the difficulty of tool selection to greatly enhance.In actual processing, for such processing Milling cutter consumption often much larger than processing conventional material, or even occurred one cutter be only capable of process more than ten workpiece Extreme case.In such case, the producer have more than 10% production cost be the consumption for cutter in terms of.

As can be seen here, the good and bad importance of milling cutter comes out from this kind of processing mode saliency, and can turn into quickly and efficiently Milling Machining is completed, reduces cost and the key factor increased the benefit.Milling cutter is that one kind is used for Milling Process, has one or more The rotary cutter of individual cutter tooth, it is mainly used in the occasions such as processing plane, step, groove, profiled surface and cut-out workpiece, work Each cutter tooth (sword) intermittently cuts the surplus of workpiece successively.

Therefore, people have to again design cutting tool accordingly, so that cutting tool is adapted to plastics on new materials The needs of processing technology.On the one hand so that cutter life is extended, and avoids tipping and fracture etc. to be possible to the meaning of defective work piece Outer generation, to reduce processing cost；On the other hand so that rhythm of production, efficiency and the product stability of machining are carried It is high.

More points are set on curve sword that can also be shown in above-mentioned each embodiment, so as to which curve sword be decomposed into more Shorter and smaller curved section, reference can be made to 201420135545.9.

The milling cutter that above-described embodiment is provided, to being carried out in the form of non-laminated containing the material of high rigidity and high tenacity simultaneously The situation of milling machining is referring to Figure 18.As shown in figure 18, the blunt blade 1 of circle cuts high rigidity machined object 2 first so that cutting edge of a knife or a sword The sky of blade 5 of profit is walked, and is not hindered.Then, when the blunt blade 1 of circle processes high tenacity machined object 3, elastic deformation occurs for machined object (referring to dotted line in figure), there is follow-up sharp blade 5 to cut, realize good processing effect.Compared with universal cutter, this hair Bright milling cutter realizes the Continuous maching to non-laminated material so that the heat dispersion of cutter is improved, and it is existing that reduction twines bits The generation of elephant, also greatly prolongs the life-span, reduces processing cost.
