The concave arc milling cutter is characterized in that a plurality of cutting edges, arc surfaces and the chip removal slots are arranged on the tool bit; the arc surfaces and the chip removal slots are arranged on two sides of each cutting edge; the diameter of the upper end of the tool bit is 17.8mm, and the diameter of the lower end of the tool bit is 22mm; each cutting edge is provided with four sides a, b, c and d; the size of the arc surfaces on two sides of each cutting edge are equal to the overall size of the chip removal slots; the arc surfaces on one sides of the cutting edges are not equal in size, and the sizes of the chip removal slots are matched with those of the arc surfaces; the arc surfaces comprise upper arc surfaces and lower arc surfaces; the upper ends of the upper arc surfaces are connected with the upper surface of the tool bit, and the lower ends of the upper arc surfaces are connected with the upper ends of the lower arc surfaces through secondary cutting edges. The concave arc milling cutter has the advantages of good chip removal effect, high milling round corner accuracy and small resonance.
Description
Technical field
The present invention relates to a kind of cutting-tool engineering field, particularly relate to a kind of concave arc milling cutter.
Background technology
In NC Machining Process, especially in some airplane parts digital control processings, the arc radius of some part sharp edge rounding is larger, the workload that pincers worker file is repaiied these positions is too large, quality is also difficult for guaranteeing, need to adopt arc cutter digital control processing to complete, existing arc cutter project organization is comparatively simple, the general employing Roound edge identical with part sharp edge arc radius completes digital control processing, the problem existing is that parts locally is while having micro-strain, when part sharp edge processes, can produce some obvious surperficial jumps, affect surface quality.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of chip removal effective, and milling fillet precision is high, the concave arc milling cutter that resonates little.
The technical scheme solving the problems of the technologies described above is as follows:
Concave arc milling cutter, comprise cutter head and handle of a knife, cutter head is arranged on handle of a knife lower end, cutter head is provided with cutting edge and chip area, described cutter head is provided with some cutting edges, and be arranged on arcwall face and the chip area on each cutting edge both sides, cutting edge decile not on cutter head circumference, the diameter of cutter head upper end is 17.8mm, lower end diameter is 22mm, described cutting edge is by a, b, c, d tetra-limits form, a lower end is connected with cutter head bottom outside, upper end is connected with lower end, b limit, described a limit is a straight line that is 3.0mm with cutter head central axes length, b limit is to be 3 ° of-5 ° of straight lines that length is 1.0mm with horizontal plane angle, upper end, b limit be connected with lower end, c limit, c limit is one section of circular arc that radius is 0.93-1.0mm, upper end, c limit is connected with lower end, d limit, it is the straight line of 3 °-5 ° with cutter head central shaft angle that described d limit is one, upper end, d limit is connected with cutter head upper surface outside, arcwall face comprises arcwall face and arc lower face, upper arcwall face upper end is connected with cutter head upper surface, between upper arcwall face lower end and arc lower face upper end, by front cutting edge, be connected.
