Description
Technical field
The utility model relates to the milling cutter field for plastic products processing, particularly a kind of double end milling cutter being mainly used in processing PPC and ABS material.
Background technology
Along with the continuous progress of science and technology, various plastic products become a part indispensable in people's life gradually, the material of common plastic products comprises PPC and ABS plastic, PPC and ABS plastic product thorough shaping last as need the Milling Process of being carried out surface by Digit Control Machine Tool, based on the characteristic of plastics itself, therefore in Milling Processes the quick frequent of cutter surface of plastic products milling easily cause plastic products consider to be worth doing slag melt after stick on rake face (chip area), and then the sharpness of cutting edge is reduced, plastic processing surface is made to produce burr, reduce the machining accuracy of product surface, follow-up Production requirement cannot be met, also need to carry out flash removed and surface finish in the later stage in the process that for this reason general plastic products are shaped in milling to remove and melt several procedures such as slag, and the edge flash removed that the later stage carries out and surface finish operation realize often by manual grinding, often have because artificial factor causes product defective and finished product accuracy is not high, affect the production qualification rate of product, also cause the heavy but inefficiency of the task of the employee on line.Therefore the milling cutter shortcoming of prior art as above is obvious, has very much the necessity improved further.
Utility model content
The purpose of this utility model is the milling cutter providing a kind of double end, its technical problem to be solved is: traditional milling cutter is in the Milling Processes of plastic products, bits slag can be sticked on operator face by the high temperature melting of cutting edge roundness and cutting edge sharpness is declined, and then easily cause milling surface of plastic products fineness decline and there is burr in edge, need to adopt the mode of manual grinding to remove the bits slag of burr on product and thawing, make complex procedures, add the task of employee, reduce production efficiency, also have impact on the production qualification rate of product.
For solving the problems of the technologies described above, the utility model provides a kind of milling cutter of double end, it comprises the handle of a knife of mast shape and is arranged on two cutter heads at described mast shape handle of a knife two ends, described two cutter heads and handle of a knife one-body molded, described two cutter heads symmetric points centered by the mid point of described mast shape handle of a knife are centrosymmetric, each described cutter head is single-blade fluting, wherein, each described cutter head includes main cutting edge and front cutting edge, described main cutting edge is circumference sword, described front cutting edge is end sword, described main cutting edge and front cutting edge are straight line sword, the relief angle of described main cutting edge is 14 °-18 °, the relief angle of described front cutting edge is 16 °-18 °, the surface finish of the rake face of described cutter head.
Be preferable over: the surface roughness of described rake face is no more than 0.2 micron.
Be preferable over: described handle of a knife is cylindrical, and the diameter being positioned at two cutter heads at described handle of a knife two ends is all less than described shank diameter.
Compared with prior art, the beneficial effects of the utility model are: the utility model in the specific implementation, the surperficial Milling Process of plastic products can be realized by a cutter, utilize the specific relief angles of main cutting edge and front cutting edge that cutting edge is had concurrently simultaneously sharp, high strength, the characteristics such as durability, and described rake face polishing makes chip removal in milling process smooth and easy, the bits slag that milling produces can not stick on rake face, and then cutting edge profit degree can not be affected by cutting edge high temperature melt, the surface smoothness of processed plastic products is protected, thus eliminate the follow-up polishing that surface of plastic products is carried out, polishing process, traditional working procedures can be unified, overall milling is realized shaping by a cutter.

Detailed description of the invention
Below with reference to accompanying drawing 1 to 3 and preferred embodiment, the milling cutter to a kind of double end that the utility model proposes specifically illustrates.
The utility model provides a kind of milling cutter of double end, it comprises the handle of a knife 1 of mast shape and is arranged on two cutter heads 2 at described mast shape handle of a knife 1 two ends, described two cutter heads 2 are one-body molded with handle of a knife 1, described two cutter heads 2 symmetric points centered by the mid point of described mast shape handle of a knife 1 are centrosymmetric, each described cutter head 2 is single-blade fluting, wherein, each described cutter head 2 includes main cutting edge 21 and front cutting edge 22, described main cutting edge 21 is circumference sword, described front cutting edge 22 is end sword, described main cutting edge 21 and front cutting edge 22 are straight line sword, the relief angle of described main cutting edge 21 is 14 °-18 °, the relief angle of described front cutting edge 22 is 16 °-18 °, the surface finish of the rake face 23 of described cutter head 2.
Preferred embodiment: the surface roughness of described rake face 23 is no more than 0.2 micron.
Preferred embodiment: described handle of a knife 1 is cylindrical, and the diameter being positioned at two cutter heads 2 at described handle of a knife 1 two ends is all less than described handle of a knife 1 diameter.In the specific implementation, the cutter head 2 at described handle of a knife 1 two ends carries out replacing and uses the utility model by making handle of a knife 1 turn around.
Preferred embodiment: clamping has automotive interior material PPC and ABS on the bright lathe of Mick, the utility model time processing bi-material is 20000min at rotating speed
-1, feeding is start processing under the condition of 5000mm/min, and the type of cooling is air cooling, and by the processing of 60 minutes, the piece surface fineness processed was good, and the phenomenon such as impulse-free robustness and thawing, meets customer demand completely.
Described on comprehensive, the technical solution of the utility model fully effectively can complete above-mentioned utility model object, and structural principle of the present utility model and the principle of work and power are all verified in an embodiment fully, and effect and the object of expection can be reached, and embodiment of the present utility model also can convert according to these principles, therefore, the utility model comprise all in claim mention all replacement contents in scope.Any equivalence change done in the utility model claim, within the scope of the claims of all genus this case applications.
