Abstract
The utility model discloses an end mill for processing thin-walled parts, which comprises a cutting edge part (1) and is characterized in that the cutting edge part (1) comprises a cylinder (2) and a cone (3), the cylinder (2) is provided with a cutting edge, the diameter of the cylinder (2) is used as a big end of the cone (3), the cone (3) extends towards a handle part, the length of the cylinder (2) plus that of the cone (3) is equal to the length of the cutting edge, and the small end of the cone (3) is connected with the handle part into a whole by a hollow knife section. Cutting is mainly carried out by the unidiameter cutting edge length zone of the end mill, namely the cutting depth is smaller than or equal to 2mm, so that the processing accuracy and the surface quality of parts are ensured. Besides, as a to-be-processed part extends down, a gap between a cut part and the cutting edge part becomes bigger. Therefore, secondary cutting does not need to be carried out by the end mill under the condition that the to-be-processed part is not divided into an upper part and a lower part to be individually processed. A boundary step cannot be produced on the processing surface, and the processing surface does not need to be ground by a tongman.
Description
Technical field
The utility model relates to a kind of slotting cutter of processing thin-walled part, relates in particular to a kind of numerical control end mill of processing thin-walled part.
Background technology
The slotting cutter that thin-walled parts such as muscle, edge strip etc. use in Milling Processes comprises the cutting blade, and described cutting portion is cylinder, and it is long that the length of cutting portion equals sword; Muscle, edge strip are subjected to the impact of cutting force larger in milling process, along with the removal of clout, the part tremor amplitude increases, when the amount of trembling acquires a certain degree in the processing, part machining area will produce secondary cutting with the cutting blade, causes playing cutter and the cut wound part; Present solution is to avoid playing cutter by the layering made allowance, be about to working position and be divided into upper and lower part processing, process first top to final size, and then processing bottom, the surplus of 0.02 ~ 0.03mm is stayed in the side during processing bottom, slotting cutter cutting blade gap because having kept 0.02 ~ 0.03mm with top when continuing the processing bottom has reached the purpose of avoiding playing cutter like this; But the boundary of part top and the bottom can form step after the processing like this, causes follow-up pincers worker polishing workload larger.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of slotting cutter that plays cutter harm but also need not increase the processing thin-walled part of follow-up pincers worker polishing operation of not only having eliminated.
For solving the problems of the technologies described above, the slotting cutter of a kind of processing thin-walled part of the present utility model, comprise the cutting blade, it is characterized in that, described cutting blade comprises the cylinder of making cutting edge, and the cone of making cutting edge that extends to the shank direction take column diameter as large end, it is long that the length that described cylinder adds cone equals sword, and described cone small end is connected as a single entity by one section empty cutter section and shank.
The tapering a of described cone makes 1 °.
Described cylinder length equals end face fillet R value and adds 2 millimeters.
The utility model has following good effect than prior art, the slotting cutter of a kind of processing thin-walled part of the present utility model, cut in the main long zone of isodiametric sword of leaning on, and namely therefore cutting depth has guaranteed machining accuracy and the surface quality of part less than or equal to 2mm; In addition along with working position to downward-extension, cut the position larger with the gap of cutting blade, thereby avoided producing secondary cutting with slotting cutter in the situation that working position is not divided into top and the bottom processing, machined surface can not produce the boundary step yet, need not the polishing of follow-up pincers worker; And because cutter has also kept cutting edge at the cone position, so this cutter also is fit to the larger cutting operating modes of cutting depth such as roughing, semifinishing.The structural design of this kind cutter is simple, and has versatility, also can change a social system by the mode of sharpening at the cutting blade of waste and old numerical control end mill, makes the waste and old cutter of part obtain the secondary utilization.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the slotting cutter of a kind of processing thin-walled part of the present utility model.
Fig. 2 is that former slotting cutter is by distributing allowance to avoid playing the machining sketch chart of cutter.
The specific embodiment
Fig. 1 shows the slotting cutter of a kind of processing thin-walled part of the present utility model, comprise cutting blade 1, it is characterized in that, described cutting blade 1 comprises the cylinder 2 of making cutting edge, and the cone 3 to the extension of shank direction take cylinder 2 diameters as large end, it is long that the length that described cylinder 2 adds cone 3 equals sword, and described cone 3 small ends are connected as a single entity by one section empty cutter section and shank.
When the tapering a of described cone 3 makes 1 °, both can effectively avoid slotting cutter and part to produce secondary cutting, can keep again the intensity of slotting cutter.
When described cylinder 2 length equal end face fillet value R and add 2 millimeters, under the prerequisite that guarantees part processing precision, can effectively avoid slotting cutter and part generation secondary cutting.
Described shank adopts staight shank, thread handle or Morse taper shank.
The slotting cutter of a kind of processing thin-walled part of the present utility model mainly cuts by the long zone of isodiametric sword, and namely therefore cutting depth has guaranteed machining accuracy and the surface quality of part less than or equal to 2mm; In addition along with working position to downward-extension, cut the position larger with the gap of cutting blade, thereby avoided producing secondary cutting with slotting cutter in the situation that working position is not divided into top and the bottom processing, machined surface can not produce the boundary step yet, need not the polishing of follow-up pincers worker; And because cutter has also kept cutting edge at the cone position, so this cutter also is fit to the larger cutting operating modes of cutting depth such as roughing, semifinishing.
Claims (5)
