Use odd blade milling cutter to undertake fast thick mill
- source:BREDA CNC Machining
The rough machining of 3mm mental allowance and machine chamfer and exhaust passageway deepness want mill to rely on mould underside. The final outline of the fast face quality that the precision work that carries work finally will come to win a demand. First craft experiments, mr Dirk Gottschalk used a diameter to contain for 20mm 4 but the milling cutter of dislocation round razor blade, bit radius R=3.
5mm. Treatment experiments to undertake on DMC 100 V Hi-dyn machining center. Adoption cutting dosage: Rotate speed N=17000r/min and feed speed F=20400mm/min. The back penetration of a cutting tool of milling cutter measures Ap=0.
75mm, side penetration of a cutting tool measures Ae=17mm. In Z axis constant and changeless circumstance falls, the time of the surface on milling mould is 35 minutes, the time that Mr Dirk Gottschalk thinks this kind of treatment spends is too long. Nextpage blazing suggests can the proposal of a blazing that economic land increases material to excise a quantity, mr Michael Pastrick puts forward the craft adviser that is company of Paul Horn cutting tool, be sought advice from the support of Mr Andreas Nitschke with the sale by his colleague, responsible technology. Replace of milling cutter of face of 4 razor blade is the Chanren milling cutter that model is DSA, 16mm of milling cutter diameter. This is one of series of Horn company's well-known DS milling cutter is improved model milling cutter. Because be the geometrical appearance that in the light of treatment the mission decides material of hard alloy cutting tool, coating and razor blade, can believe firmly milling cutter of integral hard alloy, machining aluminium alloy, other especially nonferrous metal, plastic increase with fiber model plastic when, have taller durability and treatment precision. Make diametical 16mm and length 101mm by MG3K of hard alloy brand milling cutter of new integral hard alloy, this kind of milling cutter is in A-F-T company is installation in Diebold, collet (the product brand mark that Diebold is company of tool of Helmut Diebold Goldring, this company expands with producing knife handle, heat cold shrink type collet and high speed main shaft are celebrated, what the Diebold-Spannfutter that alludes here points to is heat bilges cold shrink type collet, interpret is noted) in, treatment has on DMC 100 V Hi-dyn machining center likewise. Because cutting tool improved the performance that discharge bits significantly, add man-hour to be able to use the back penetration of a cutting tool of Ap=8mm to measure, the penetration of a cutting tool that quantity of such penetration of a cutting tool should use than face milling cutter is measured full tower above 10 times. Should use side penetration of a cutting tool to measure Ae=12mm, horn cutting tool is in Z axis is constant and changeless with the time that tilts 5 minutes. The scale that with good impression to the person in handling time respect basic time is opposite 35 minutes 8 minutes (fall in case of similar cutting tool durability) showed a kind of concern, "Although deepness of bigger penetration of a cutting tool, treatment process is very smooth still, the dependability that this machines a process to new treatment strategy is very advantageous. " Dirk Gottschalk expresses. Although make one rough calculation to cutting tool charge, also can make the proprietor of an enterprise feels be convinced. Of 4 but the face milling cutter of dislocation razor blade, its charge is 200 euro full, each but dislocation razor blade is to cannot undertake weighing grinding, every knife film contract is 4 euro. Although dislocation of round razor blade 3, the fare state of affairs of generation still is advantageous to Chan Renxi knife. Of odd blade milling cutter purchase cost to be 138 euro, considering grind charge again, its the total cost of total cost and face milling cutter is roughly identical. If notice 8 minutes of scale to 35 minutes, its report uses cost rate to go up to machine tool hour, can bring about of course greatly apt Horn respect. And Mr Dirk Gottschalk saw another advantages again: "Series of DS milling cutter is by have geometry of all sorts of different razor blade appearance and (0.
2 ～ 16) the milling cutter of integral hard alloy of a variety of Mm diameters forms. For the much breed circumstance that this processes work to us, the product with this kind of older range chart has clear advantage undoubtedly. " because, the treatment limitation that milling expert exists gladly to cutting tool, clamping apparatus and machine tool has thorough research. Be opposite aluminium alloy and plastic treatment and the treatment to large mould, he realises odd blade milling cutter is existing to enlarge the potential faculty of scope of application. Mr Dirk Gottschalk in formulate these plan when, got the help of Mr Michael Pastrick. Because the high quality of Horn company product and treatment process are responsible, can score good gain jointly thereby, offer new possibility in the respect such as concerned time, quality and efficiency namely, also increased the competitive capacity of A-F-T company significantly from this.
