Use milling chuck to improve manufacturing efficiency

4mm) milling cutter of end panel of hard alloy of carbide of 4 cutting chamfer. Vice-president Mr Jack Burley of Big Kaiser company judges exposition and argumentation: "To spare parts itself, this keyway is a crucial position, having conclusive effect to the success or failure of whole craft. " graph the 1 method before collecting in order to, because cutting tool clamping force is insufficient, noise of easy generation flutter is mixed when treatment produce vibration. After using new-style milling to machine chuck, the clamp tigidity of cutting tool increases, because this can make the treatment cycle of this company machine tool shortens, raise noise of cutting precision flutter so far, if why come with enough tigidity,this company still was not solved milling cutter of end panel of clamp carbide hard alloy, in order to achieve the cutting deepness that they need (DOC) the high rate that with whorl high speed thick milling treatment needs. Manufactory of Imo water pump realizes, the clamping force of cutting tool is improper, the appearance that may cause treatment hind is bright and clean degree coarse, and meet what frequent ground causes cutting tool rupture and the adhesion of workpiece. For this, this manufactory undertook a series of experiment. Company of J&H machine tool had various tests inside the Charlotte factory of city of its North Carolina. During the experiment, they once tried all sorts of methods, but factual proof, all these appears not suit is actual, in treatment cycle is mixed homocentric spend a respect cannot satisfactory. For example, the knife clip that uses end panel milling cutter and head of ER bedspring card have certain limitation. Anyhow, to this domain character, means of clamp of these two kinds of cutting tool lacks necessary rigid characteristic, the treatment rate that this means a part will be slower. Mr Hunter explanation says: "During rough machining, ER bedspring blocks a head to be able to make cutting tool is pulled from inside knife clip actually, the measure that creates cutting treatment thereby does not reach the designated position. Clip of knife of end panel milling cutter can produce additional power to cutting tool itself. When it uses such means clamp, I notice cutting tool can arise to wear away additionally. The oscillatory meeting of excessive causes the stress of excessive, bring about end panel milling cutter to shrink back backward thereby. Use the collet of this kind of type, we can obtain the in part of cutting deepness only. In addition, the traversal speed that uses as a result of us is inferior, collet is easy with workpiece adhesion. " accurate join method passes a few weeks try after moving, still cannot satisfy booked operation parameter, this test working group begins to seek an opinion publicly, seek advice to district director Mr Richard Bevers of Big Kaiser company. It is OK that this job shops was chosen according to the standard of certain respect as compatible as main shaft interface Capto C6 chuck. Place of no less than Mr Burley explains in that way, chuck of Capto C6 interface has certain rigid base, if use system of appropriate cutting tool clamp, its tigidity still can be strengthened further. Mr Burley explanation says: "Interface of this main shaft by taper of type of a 3 leaves fair buckle contact composition, when because this is become,putting its interface, do not need to use drive key connection actually. Because its are in miniature taper over, because this can make its accurate on main shaft,locate. " produce manufacturer as a system of concessionary Coromant Capto tool, big Kaiser company can provide systems of a variety of cutting tool clamp, they can match with the main shaft photograph that deserves to have Capto interface. After the course applies the examine and verify of the domain to this, the milling treatment chuck that Mr Bevers thinks to use firm of Mega Double Power can be solved rather the flutter noise problem related two his clamping apparatus. Offer money through inventory next, cutting tool can be installed instantly in the operating system. Because oscillatory problem got settlement, make manufactory of Imo water pump raised DOC level thereby, and feed rate and working rate. Graph 2 use this kind of configuration, but the density of refrigerative fluid is helpful for cutting chamfer rinse, even if when use interior does not take cooling fluid to input the cutting tool of aperture, also be such taller homocentric degree of view according to the manufacturer, the means of the tigidity of clamping apparatus itself and its clamp cutting tool can eliminate the vibration of the machine tool. When be equivalent to the diameter of 4 times, the configuration means of its locknut can make the precision of chuck is achieved 0.

0002 In, this means all cutting chamfer that contacts with work look to be able to undertake balanced cutting. Rigid clamp begins from the external diameter of device of cutting tool clamp, this device is completely symmetrical. To make cutting tool tightens solid perch, operator needs to use a special wrench only, screw this one nut by the clockwise went, this kind of spanner duplicates according to the spanner of Mega company, match with the diameter of nut, can use as an one-way clutch. It can clip smooth external diameter closely, but won't imprint in tooth of spanner of the bequeath on clamp nut. After screwing entirely when nut, double interface can be formed between device of cutting tool clamp and nut. Mr Burley says: "This kind of milling machines chuck to have very tall clamping force, its clamping force is equivalent to the times above of 7~10 of common collet. If be compared with the clamping apparatus of end panel milling cutter, it can provide precision of very outstanding radial and jumpy error, higher quality and damping capability. When cutting tool cuts work, rely on these ability to be able to raise cutting rate greatly, because the clamp structure of cutting tool has tremendous tigidity, plus the vibration isolation function of cutting tool, make cutting treatment more smooth and successful. Mr Burley estimates, after manufactory of Imo water pump was employing solution of this kind of cutting tool, compare with the photograph of clamping apparatus of end panel milling cutter of former ER collet and standard, its DOC efficiency and feed rate can rise 3 times above. Imo firm was increasing cutting efficiency respect to already obtained striking progress, all these also should be attributed to Big Kaiser company doubleclick a technology (DS) . The device of cutting tool clamp of company of all Big Kaiser has the distinguishing feature of a standard, its circumjacent cooling system can convey cooling fluid directly through clamping apparatus over the edge of end panel milling cutter. To this Mr Burley the explanation says: "Cutting tool has a lot of alveolus on clamp device, allow cooling fluid to had flowed from Xiaokong, this not only be helpful for rushing to cut bits, and OK still and cooling edge. " since rose in May 2007, this Che Xi machines a machine tool to begin the Monroe manufacturer in production company of Imo water pump to settle down. As a result of the process capability of itself of this machine tool, machine the function of chuck plus new-style milling, make the screw production of this factory realized flow operation. This company besides improve cutting tool service life besides, still make the time of card of average key trial assembly of cutting tool spare 35% , and improved manufacturing efficiency greatly. Mr Hunter says: "We notice, the service life of this kind of specific cutting tool had very big rise, but we just increased a chuck just. " the view according to everybody, although the first cost of itself of system of cutting tool clamp wants to compare other options a few costlier, but still be worth configuration. Summary of final Mr Bevers says: "Cutting tool system is crucial, it is having very apparent effect to improving manufacturing efficiency. But from long-term in light of, this should be compared managing on system of cutting tool clamp a few dollars are worth to take seriously more. This should be compared managing on system of cutting tool clamp a few dollars are worth to take seriously more.. CNC Milling CNC Machining
