Paper-cover but of dislocation milling cutter reasonable choose

1 but of dislocation face milling cutter choose a point to planar milling, general first selection but dislocation face milling cutter, because but dislocation face milling cutter has more end panel to age effectively, treatment efficiency is tall, suit milling to cut the plane under deep 10mm relatively. 1) but diameter of dislocation face milling cutter and the option that tine counts but D of diameter of dislocation face milling cutter is the diameter that points to circle of circumgyrate of point of a knife. When using symmetrical milling method, press width of milling workpiece surface normally, namely Ae of quantity of side penetration of a cutting tool comes diameter of estimation face milling cutter, namely D=(1.

1 ～ 1.

6)ae. The choice can return place of cutting tool of Lv of take an examination to need power to should be in limits of machine tool rated power when diameter of dislocation face milling cutter, also can come according to D of diameter of machine tool main shaft accordingly estimation, at this moment cutting tool diameter should satisfy D<1.

5d. But what the tine number of dislocation face milling cutter follows pattern of size of milling cutter diameter and bit clamp connection is different and different. Will tell commonly, grow in quantity ages number can improve milling productivity; But get the factor such as power of structure of intensity of the treatment material, space that hold bit, tooth, clamp, machine tool and tigidity limitation, but number of tooth of dislocation face mill is unfavorable also and overmuch. Milling cutter of thick tooth flank basically measures rough machining, workpiece with Yu Dayu the treatment circumstance with milling softer or bigger width; Tooth flank milling cutter is commonly used series in; Serration and milling cutter of close tooth flank basically measure treatment of cutting, casing or milling nonferrous metal and aluminium alloy part with Yu Xiaoyong. Serration and close tine milling cutter age in every the case with not big feed falls, still can obtain than thick, medium the feed with tine big milling cutter, realize taller productivity. 2) but the choice A of parameter of geometry of dislocation face milling cutter.

Before horny choice chooses correctly but P of γ of the horn before the axial of dislocation face milling cutter is very important: When choosing bigger γ P, cutting blade is sharp, cutting is light, consume power little, but edge intensity is low; When choosing lesser γ P, cutting blade intensity increases, but cutting force also increases, consume power grow in quantity. But the choice range of the horn before axial of dislocation face milling cutter is bigger, need a basis to machine a circumstance actually logical choice. When cutting plasticity material, appropriate is chosen bigger before horn; When cutting brittleness material, appropriate is chosen lesser before horn; When material of cutting difficult treatment, need integrated consideration. When tooth negative charge is bigger, appropriate is chosen lesser before horn; Conversely, can choose bigger before horn. But the before choosing principle and axial role of F of γ of the horn before dislocation face milling cutter is radial is similar, but be restricted as a result of place of milling cutter structure, the span of γ F is not big. In addition, f of γ of the horn before radial still affects the way that discharge bits directly: When γ F is bigger, make cut bits to leave work; When γ F is lesser, make cut bits to be pressed to workpiece. Usually, the range of application of face milling cutter of γ F = 0 is wider, but when choosing, still need to combine γ P to consider integratedly. The different combination of F of γ of the horn before Gp of the horn before axial and radial, the face milling cutter that can form type of the horn before differring (1) seeing a table. Characteristic of type of the horn before the horn before expressing 1 milling cutter combines type and characteristic Shuang Zhengqian horn (Gp>0, gf>0) cutting bits of light, platoon is successful. Apply to treatment weak data and stainless steel, refractory steel, common steel, cast-iron etc. Machine tool power is lesser, answer when machining complex tigidity is poor preferential choose pair of actor before losing (Gp<0, gf<0) impact resistance is strong, can use bit of the horn after notting have. Apply to treatment cast steel, cast-iron, high strenth steel to wait. The horn before be being lost higher to the power of the machine tool and rigid requirement (Gp>0, gf<0) integrated above two sort characteristic, in make cutting tool has as far as possible enough fight concussion ability while have certain and sharp sex and property of better platoon bits again. Apply to treatment grey mouth is steel, cast-iron, cast-iron etc, advantage B is had when large surplus milling.

The choice of tool cutting edge angle but the tool cutting edge angle of dislocation face milling cutter basically affects feed force and perpendicular feed force. 45 ° tool cutting edge angle applies to treatment cast-iron or hang in main shaft of mill boring machine extend longer the treatment below the condition. The radial component of force of force of the feed when using 45 ° tool cutting edge angle and axial component of force are roughly equal, cutting force distributings in the part with longer edge, have fight very well brace up quality; 60 ° tool cutting edge angle applies to the rough machining on mill boring machine, but relatively reduce feed force substantially, marked improvement is fought brace up quality; 75 ° tool cutting edge angle is the most commonly used tool cutting edge angle, it is better that as a result of its edge uses a sex, because this has better treatment economy. 3) but the chooses milling razor blade cutting knife of razor blade of dislocation face milling cutter is long can measure according to penetration of a cutting tool of the biggest back will choose, normally penetration of a cutting tool of the biggest back measures the 2/3 ～ 3/4 that can grow for cutting blade; When the 1/2 that when mental allowance insufficient cutting blade grows, should change small norms razor blade. But the alternative with simple material of razor blade of dislocation face milling cutter is very main also, should according to be being added the material of workpiece chooses corresponding knife sheet to pledge character. The razor blade that chooses coating name is attainable better cutting effect, prolong bit service life substantially. 2.
