Accurate cutting tool produces manufacturer two solutions make Licon Mt of machine tool manufacturer is benefited from which, saved a lot of time and money to be used at the working procedure of spare parts milling of machining center. "We are right before handling time is very dissatisfactory. " Licon Mt of manufacturer of famous machine tool is machined / say of Harald Dammann of working preparation manager. The handlers that two working procedure with a successive spare parts let have experience feels arduous with costly. This spare parts is model be been in by installation LiflexII444 double main shaft is used on machining center of 5 axes horizontal. Besides machine tool of type of much axis circumgyrate and special machine tool, liflex series is modular the main sale pillar that machining center is Licon Mt. Rough machining to finish machining special milling cutting tool machines working procedure is have rough machining and precision work to the aperture on Z slide block, the length of its aperture is 1400mm, wide and it is 300mm high respectively. The weight that makes heavy work by nodular cast iron is 200kg about, tensile strength is 600N/mm2. Through be opposite circumferential mill machines aperture to expand aperture diameter from 200mm 241mm. No matter rough machining returns the finish machining that is back-to-back move, licon Mt all uses special milling cutter. Of rough machining cutting tool extend length to be 553mm. "To reach the treatment mass of an expectation, enough stability becomes this to grow the crucial essential factor of cutting tool. " Harald Dammann say. Of course, be based on the light account that carries maneuverability by hand, be more than the knife handle with heavy 10kg is not to use rolled steel to use aluminous material to be made however. This cannot satisfy the requirement of tall stability again. Machine the stability of the process and low noise to come true, milling cutter and but dislocation razor blade is chased after by the market hold in both hands. Using much rough machining of advantage of rough machining of face mill bit body is to be in to contain a horizontal stroke / the horizontal that establishs milling cutter large machining center undertakes 4 axes. This working procedure needs 56min, the finish machining of all sorts of different faces of back-to-back move will last 48min. To reduce handling time, at the beginning of September 2015, treatment manager / the Martin Huber that Marcus Breymayer of personnel of CAM process designing finds Walter Germany company seeks a help. Old since, this applied technology personnel that has experience maintains friendly collaboration with Licon Mt all the time. Be in a few days short in, he found a good solution for these two working procedure. From September 2015 bottom, the Octagon (that the F2334 of face mill bit body that uses Walter replaces the Walter that uses so is octahedral) milling cutter undertakes rough machining. "Its distinct advantage is reflect through quiet movement and reliable craft security. " Huber explains respecting, "Contain facet but dislocation circle razor blade and stable razor blade are fixed make when rough machining of difficult treatment material, realized tall feed and metal to cut rate. " the F5041 Blaxx(Hei Fengxia that tightens the precision work that follow to use Walter) square shoulder milling cutter is replaced by the square shoulder milling cutter of the other vendor that uses at present. Tangential the milling system that arranges bit and but the perfect combination of dislocation razor blade " F5041 is treatment stability only, craft security is designed with tall productivity. " Mr Huber emphasizes say, "The foundation of these advantages is to pass specializationed finishing, blaxx(Hei Fengxia) the advantage that combined cutter hub and razor blade faultlessly, make cutting tool intensity increases, ability of heat-resisting, wear-resisting rises greatly. Bit is become by the design of 4 screw type model the accurate 90 ° on cutting blade and workpiece. " Walter milling cutter CVD coating and Yin Hu of use Tigertec Silver() of the technology but dislocation razor blade and tangential decorate bit milling system to be united in wedlock faultlessly together. The alumina coating of the small structure in the coating of this kind of special heat-resisting, wear-resisting, made contribution to reduce handling time. Particularly slick surface reduced attrition to wear away chemically. The Silver(Yin Hu that regards a directive as coating) can discern easily wear away. Razor blade of circle of 10 when the diameter that feed speed gets rising significantly be usinged at rough machining contains for milling cutter of 160mm circle razor blade 8 blade, technology of use Tigertec-Silver coating. Through converting this is planted bit, the feed of every tine (Fz) from 0. 28mm rises 0.
8mm, the cutting deepness that circulates every time (Ap) from 0.
5mm raises 1mm. Transverse feed is 1mm but the angle of effective cutting clench the teeth of dislocation round razor blade is Kappa 20 ° , and the angle of clench the teeth of razor blade of Octagon 8 horn is 45 ° . "Kappa angle cost is lower, cut bits thinner jump over with feed tall. " Huber say. Feed speed (Vf) raises 2700mm/min from 850mm/min. Handling time reduces 10min from 56min. "We can win so big improvement without anticipation. " Dammann says gladly. Every workpiece saves handling time to be 46min, can increase 76h productivity every year, be equivalent to reaching the economic range of 4 digit. Solution another positive results are: Cut bits thinner, less also to the bear of milling spindle, machine tool movement is quieter. Little vibration means a machine tool to obtain more protection. To finish machining, those who use is the milling cutter of Walter square shoulder of diametical 63mm, enchase 7 squares but dislocation razor blade. When competitive product uses 6 identical square bit, the milling cutter of Walter is 6 tangential decorate but dislocation razor blade, 4 razor blade and a double blade that accompany where a thing can be put to best use of wide mill of essence of life but dislocation razor blade. This product is by a kind the material WAK15 of special wear-resisting is made, have a particularly long deputy cutting knife. Form tall every tine feed from this (Fz) , improved exterior quality significantly (Ra=0.
5 replace Ra=0.
1) . Grind cutting tool through using the energy of Walter. Every tine feed from 0.
08mm rises 2.
5mm. Feed speed (Vf) raises 3500mm/min and handling time to reduce 56min from 48min from 300mm/min. Every workpiece saves handling time to be 43min, can increase 72h productivity every year, can produce 100 parts more, economic limits is in 4 digit. "Can reclaim quickly through economic time the investment to more valuable Walter cutting tool. " say of treatment manager complement, "Convert after new-style cutting tool, finish machining craft is more more reliable than before, we are at present OK unmanned operation. " previously, no matter be in rough machining, still be finish machining all uses emulsifying agent refrigeration, at present these two working procedure realize treatment doing type entirely. Workpiece is clean and clean charge is reduced apparently. CNC Milling
