Railroad more and more the main carriage way of future be regardinged as, journey of the short distance in be opposite especially. Its part reason depends on environmental protection, but also exhibit with the bitter fleabane break out of high speed train about. The many countries that include China inside draft the high speed railroad in the kilometer that build number and common railroad. The spare parts that rail and railroad traffic involve is unusually various, and all sorts of demand that this kind of dilate asks to have higher efficiency talent to satisfy relevant spare parts to make a trade. The competition ability that contented contract asks also is those who improve manufacturing performance is main because of,move- - and this can machine a method to give through first-rate mostly implementation. Railroad traffic looks with the wheel from the angle of machine tool or cutting cutting tool, railroad traffic belongs to treatment with the wheel concentrated model product, and also be the target of application development likewise. Railroad wheel loaded vehicle involves machinery of treatment special type, need often maintains maintenance. Among them cutting tool choice and specific application depend on the circumstance of the kind that needs turning wheel and wheel body. No less than is all treatment is same, machine tool power can produce a few effects especially to cutting parameter, and the biggest change cutting deepness to be able to shorten cutting time of whole. If machine tool power is enough, wheel outline can shape through walking along knife turning. Otherwise, must the wheel outline that grading machines ability to obtain place to need and dimension. When the wheel that machines especially gets attrition force drive, as a lot of do not fall turbine bed is same, the wheel installs park railroad traffic to go up, because this may need many level,ability can complete treatment. The basis machines type and machine tool circumstance, the method that specific applying can have a lot of kinds. Cut bits control to answer first consideration, falling especially the space in turbine bed suffers in a limited time, produce efficiency and the potential damage risk that avoid wheel and cutting tool to keep tall, more should such. Stem from this reason, intensity of line of the control that cut bits, blade and smooth cutting element should merge into but in the development of form of chamfer of dislocation razor blade. To achieve good performance and taller manufacturing efficiency, qualitative combination of bit chamfer form and material is crucial. Bit is secured in knife box, install the knife handle that is used at wheel loaded vehicle to go up again next, and bit often keeps tangential undertake cutting. Lozenge CNMX razor blade has left hand-type and right hand-type to be able to offer an alternative, suit the flange profiling working procedure of alloy steel. Below the case that reasonable applying, these cutting tool can machine a very tall wheel circularity, and be in whole cutting process, the control that cut bits is good. The function that break bits depends on tool cutting edge angle of wheel material quality, razor blade and use cutting rate. The proposal uses first-rate speed and feed combination, undertake cutting along a certain part of wheel outline. The 19mm norms razor blade that develops recently is located in finish machining working procedure surely, have a variety of suiting steel is machined even the bit material that partial oil hard data processes can offer an alternative character. Installation of this kind of razor blade is in right hand-type or box of left hand-type knife, provides knife cushion can protect knife handle and bit not only, and the heat during conducing to cutting is delivered. Among them knife box passes firmly of very reliable orgnaization of commonly used locking to originally to reach the designated position surely. Nextpage to these working procedure, use material of new generation hard alloy to be able to promote function and production efficiency considerably character. The development work with all sorts of simple material is undertaking steadily in, in an attempt to offers persistent improvement for the client. Abrade of face of the knife after at present the wheel wears away to behave those who be certain level mostly, hind knife face coating comes off or hot crack, to this kind of wheel, can use material of general razor blade to pledge GC4215 undertakes cutting. If wheel loss is heavier, and use low speed machine tool, so ask cutting blade is very tough, can use material to pledge GC4225 undertakes cutting right now. If wheel outline wears away not to father,weigh, to shorten handling time, can use material qualitative GC3015 and cutting undertakes when applying taller cutting parameter; And serious to injury wheel, can use material to pledge SH undertakes cutting below low cutting speed. In addition, new to making railroad wheel, also have the solution that can offer an alternative. Solution of the cutting tool that be not mark made full use of type of wheel design, machine tool and cutting operating mode. The component of most cutting tool of these solutions all is based on standard concept, but can design what can optimize existing applying all sorts of combination. These solutions are based on the most agile and what provide tigidity most is modular full Capto of coke of system of cutting tool clamp. This system is bringing into the product line of new machine tool of wheel of railroad of production high speed. Milling housing is inside railroad industry, the spare parts is not stable during involving drive and the application of high accuracy finish machining that make movables taste cast-iron housing to often can bring about cutting, and create manufacturing problem easily. It is a case of some company below, although this company used the most advanced new-style machine tool, but the insufficient place that still cannot make up for improper cutting cutting tool. Workpiece is not stabilized and clamp is not firm mean cutting force to be able to bring about vibration greatly too, such very reach strict tolerancepublic errand range hard. No less than is all and contemporary the product is same, reduce weight to be able to affect a design, and the product that this also applies to and so on of railroad actuating device. cast-iron housing, this meeting affects the treatment stability between campaign, because housing wall is thinner, and want first consideration again on the structure its function. Below this kind of circumstance, this company undertook transforming to the machine tool even, in order to provide taller stability, make its have 5-20 the tall productivity that housing batch place requires and flexibility. But, rough machining passes apparently the finish machining working procedure that crosses deep ripple mark to be able to affect sequel, 0 what need to amount to different ability taking a knife 6 times to obtain certain measure place to ask normally.
The Xiaogong of 05mm less than is poor. This company must go to mill of essence of face of a few spare partses 0.
02mm less than, in order to make certain housing measure is in tolerancepublic errand limits in. Its surface is bright and clean spend a requirement to be Ra 3.
2 micron. Because be put in serious time in housing production / quality problem, because of this machine job shops is badly in need of suiting accurate on high-powered machine tool treatment not to stabilize the contemporary cutting cutting tool of housing. Final, this company passes as close as Shanteweikekeleman's expert cooperation, rolled out new blame tradition solution jointly: The diameter is the Century milling cutter of 63mm, deserve to have qualitative bit of material of H10 hard alloy. Milling cutter of this kind of finish machining is developed for face mill aluminium alloy only, but also apply to cast-iron treatment. The vibration when cutting of this cutting tool is dinky, achieve easily so 0.
The Xiaogong of 02mm needs a requirement, and can be obtained upright at Ra 0.
6-1.
The surface between 1 micron is bright and clean degree. The performance when milling cutter of face of CoroMill Century 590 is machining cast-iron crust is very excellent- - cutting rate comes high 190m/min, feed 1819 Mm/min, cutting tool life can amount to 200 minutes, use a Wiper (Xiu Guangren) bit treatment also can gain the face that accords with a requirement 150 minutes bright and clean degree. Most housing needs finish machining to walk along a knife to finish only, but to bigger housing, undertake twice taking a knife with respect to need: Deepness of the cutting when taking a knife for the first time is amounted to 0.
05 to 0.
10mm, take a knife the 2nd times low to 0 Mm. Take the wave shape outline with knife general all and redundant purify for the first time, and walk along a knife the 2nd times to be able to ensure tolerancepublic errand is in 0.
In the limits of 02mm, and the surface is bright and clean degree also maintain in Ra 3.
In 2 micron. Should realise, cutting cutting tool develops the latent capacity of a contain to be able to win rich and generous get one's own back. What in be being produced before, encounter is serious and difficult, now machine job shops already formed a first-rate to machine craft, make the treatment of railroad product had production consistency of cycle weak point, quality security of tall, treatment is advanced advantage.
