1 foreword is built to satisfy national economy (especially Bao Gang 2 period project) right homebred but the demand of dislocation cutting tool, my company from " 75 " during begin to introduce Suo Er of German flower case (Ingersoll) company MAX-I but the manufacturing technology of product of series of dislocation milling cutter and whole set of equipment, the I-DEAS application software that purchases several SUN workstation and SDRC company again subsequently is wrapped, apply advanced CAD/CAM technology to develop production homebred but dislocation cutting tool. Heretofore, my company already developed those who produced nearly 300 nearly 50 breed, norms but dislocation milling cutter and more than kinds 70 but dislocation razor blade, still can produce products of all sorts of the cutting tool that be not mark in addition, for our country but of design of dislocation cutting tool, production level rise made contribution. 2 MAX-I but the characteristic of dislocation milling cutter (A)MAX-I razor blade (the comparison of 1 MAX-I of graph of B) common razor blade razor blade and common razor blade in the position on cutter hub MAX-I but series of dislocation milling cutter is a kind of structure the numerical control cutting tool with advanced, good performance, apply to alloy of treatment steel, cast-iron on the numerical control machine tool such as machining center, heat-resisting, nonferrous metal to reach all sorts of special material workpiece, but the treatment requirement of high accuracy of machine tool of better contented numerical control, efficient, automation. MAX-I but dislocation milling cutter has the following characteristic: The axial of MAX-I milling cutter beats the demand that waits for main precision index to compare ~ 5342-85 of national level GB5340 rises significantly, if the standard stipulates the axial of Ø200 face milling cutter is jumpy,the quantity is 0.

05mm, MAX-I milling cutter is achieved 0.

02mm; The end panel of face of standard regulation bearing beats the quantity is 0.

02mm, MAX-I milling cutter is achieved 0.

003mm. Lever of MAX-I milling cutter kind cutting tool knife handle uses cut Ping Bing or 7: 24 awl handle, aperture kind cutting tool knife handle also can place a share with outfit of numerical control machine tool good match, can come true to assemble and unassemble automatically conveniently. The razor blade of MAX-I milling cutter is used tangential arrange, bear of cutting force sectional big, because this can develop machine tool efficiency adequately, implementation big feed, big cut deep treatment. Because bit gets power sectional big, wear away area is wide, all round edge wear away not easily, accordingly cutting blade intensity rises, cause collapse blade not easily. Graph 1 go up in cutter hub for MAX-I razor blade and common razor blade positional comparison. The graph tightening solid of graph 2 MAX-I razor blade sketch map of 3 LY-004 milling cutter pursues molded lines of 4 razor blade takes the picture that accept a plan AMAX-I of the horn before amlposition of 5 razor blade is worth Δ and radial razor blade uses cutting force clamp, can secure with a bolt only in knife chamfer (2) seeing a picture, cutting tool structure is simple, the chamfer that hold bit is big, platoon bits is fluent, metallic excision rate is high, and bit changes fast, location is exact, do not need to use change bit and the special device that measure fixed position reach all sorts of clamping apparatus. The cutter hub of MAX-I milling cutter uses material of high grade alloy steel to make, after changing processing through moving qualitative, nitrogen, have very tall hardness and strength, added milling cutter service life. 3 MAX-I but the design method of dislocation milling cutter with LY-004 milling cutter (3) seeing a picture is an introduction its devise a method. Give molded lines of cutting tool standard in the draw on the computer above all; Have section to molded lines of cutting tool standard next, every paragraphs part to be comprised by the edge line of hard alloy razor blade point-blank; Have each bit building receiving inside tolerancepublic errand limits of the regulation again. If the graph is shown 4 times, edge molded lines is built by bit A, B, C receive and become. Bit is built by edge molded lines receive after been arrange, MAX-I of Er of all alone of basis flower case but the structure of dislocation milling cutter, can adopt method of below in order to two kinds of designs: Bit amlposition forms cutting fall basis the graph shows geometrical concern 5 times, the computational formula of A of the horn before bit amlposition is worth Δ and radial is Δ respectively =1[Wb+C1 √ (D2-1)C21+W2b]2a=arcsin(2 Δ ) in D type: Wb -- bit width is in axial is sectional the magnanimity that go up is worth C1 -- hind the corner differs D -- the Δ value that diameter of cutting blade circumgyrate gives bit by computation undertakes amlposition, turn to the requirement next locally, design the corresponding chamfer that discharge bits, empty tool bore and bolt hole again can. The graph shows bit A 4 times to press this method design namely. After the part after turning directly has arranged bit, do not undertake amlposition, the cutting blade that circles bit directly however turns hind horn. The graph shows B of oblique plane razor blade, C 4 times to press this method design namely. This design method can assure the accuracy of edge molded lines. 4 MAX-I but the MAX-I of main precision index of dislocation milling cutter but dislocation milling cutter (series) main precision index sees a table 1. Watch 1 MAX-I milling cutter (series) circle of type of milling cutter of main precision index is jumpy (the Kong Gong inside Mm) is poor (Mm) petiole public errand (public errand of Mm) datum plane (thick milling cutter of plane of Mm) radial axial 0.
