High speed milling improves manufacturing efficiency

In 00005in (1? In=25.

4? Mm, similarly hereinafter) , the major work that its produce, treatment precision is in 0.

0001~0.

Between 0003in. Recently, x-Cell company hopes in electrode and appearance outline producer the face raises his to manufacture efficiency, decide to machine a domain to choose credible solution in HSM high speed. In X-Cell company 10000ft2 (1ft2=0.

093m2, similarly hereinafter) the CNC that modernization has inside workshop machines equipment, include machine tool of cut of line of hole puncher, EDM and discharge of numerical control EDM to machine a machine tool among them. This company still is engaged in the production of treatment of milling of high speed strong voice and electrode. President Mr Ron Novel of X-Cell company says: "X-Cell company still grew cooperative relationship with a few abroad suppliers, in order to support them the production of component of low cost mould. We have the mould sampling capacity in compressor of vertical of compressor of horizontal of fine of 120t Nissei day and fine of 80t Nissei day. Our qualitative check branch is in charge of the first mould and pair of spare partses examine and test and verify. " this busy job shops need improves manufacturing efficiency further, so that can continue to compete with manufacturer of domestic and international die, machine a respect in electrode production and appearance outline especially. Mr Novel says: "In the past, major work is use artificial means or finish in the treatment on obsolete equipment. " cutting treatment is before milling machine of high speed of the MC640L that chooses Sodick company CNC, mr Novel studied his equipment chooses plan carefully. Mr Novel says: "The milling machine of CNC high speed of Sodick company is the high speed milling machine that distributes motor of wired sex drive exclusively, its price just in time is in we can in enough susceptive limits. After cutting trying in the course, the machine tool that we assure Sodick company and other the machine tool look that we are considering is compared, the exterior surface roughness that its machine is better, repeat precision taller. Because use linear motor, its repeat precision to be able to keep old, accordingly we need not worry about attaint of ball guide screw or tatty problem. " according to P of manager of Sodick company sale.

The view of Mr Naughton, use system of linear and motor drive not to need ball guide screw, also won't produce the relevant back unoccupied place error that causes because of ball guide screw accordingly. Mr Naughton explanation says: "The rate of extremely tall axis that system of linear and motor drive has 1440in/min and 1.

The acceleration of 2G. Because high speed is hard the data capacity that voice milling treatment excises is less, because this suits very much,introduce linear and motor drive. Unlike drive of ball guide screw, linear motor is OK permanent job, do not need to change. " this milling machine is OK electrode of milling treatment black lead or electrode of cupreous tungsten alloy, and the tool steel with cutting treatment hard temper by dipping in water, have very tall treatment precision. Mr Novel explanation says: "It can be used at the finish machining inside dinky area, below a lot of circumstances, need not electrode and operation of EDM discharge treatment, we can undertake to steel of strong tool of temper by dipping in water high accuracy cutting is machined (graph 2) . Accordingly, below a lot of circumstances, it also does not need to use planar grinder treatment. To improve treatment precision is mixed eliminate vibration, use cold shrink type clamp cutting tool is indispensable. The radial and jumpy error of this kind of cutting tool is extremely small, and have taller clamping force than common collet. Because was configured cold shrink type collet, the outspread length that its increase can achieve outline appearance, and apply to treatment of workpiece parietal milling. The heavy-duty and cast-iron base of the machine tool and cast-iron beam also increased the tigidity of the machine tool, because this is had,fight outstandingly brace up and suck brace up characteristic. The feedback data of vitreous grating feet can make sure precision of treatment of machine tool cutting is mixed repeat precision, because the machine tool did not use ball guide screw, accordingly we can measure the real position of the machine tool from beginning to end, because reading is not accurate,need not worry and cause wear away. " graph 2 " pinhole runner " the process capability of drive motor and machine tool combines the linear of inchoate treatment circumstance of electrode a whole, the treatment precision that can maintain a machine tool and repeat precision. Because not be,come with athletic component the workbench of drive machine tool, this also conduces to the vibration that reduces a machine tool, allow a machine tool to make move more quickly with more accurate process designing and answer time. Mr Novel says: "Because do not have athletic component,the another advantage of linear drive motor is, because of guide screw of this nonexistent also ball wear away and change problem. The precision of linear motor keeps changeless from beginning to end. In the linear slideway that the component of only movement is roller bearing under workbench. The work area in the machine tool uses the athletic component be apart with proper sealed way and other machine tools to leave, because this iron and steel cuts bits or black lead grain won't outside discharge and cause wear away prematurely. Also use sealed protection through cooling main shaft, plus the temperature of main shaft control is in certain limits, repeat treatment precision because of what this assured a machine tool again. " Nextpage " from the point of groomed viewpoint, the operation control system that is a foundation with Windows makes its were achieved almost to the transition of Sodick milling machine without seam connective level. " Mr Novel says so, "When transferring to new machine tool, often existing curve of a learning, beginning the time that produces a part is very short. We feel enough fortunately, the company has to machine a respect to have the jockey of experience very much in strong voice milling, he helped us reduce study time substantially, the day that starts formally from the machine tool calculates two when rise to come inside 3 weeks, we make its efficiency achieved 80~85% . the machine tool operator that be machined at CNC milling to an essence and has experience of rich process designing, although he does not have high speed to machine the setting of the respect, but the time that I think to spend about 2 months can reach same level. Sodick company is grooming we also gave very great help in the process, they and operator maintain close connection, can operate a machine tool adroitly till them. Before machine tool shipment goes to our company, sodick company can arrange our operator to undertake to their factory the aggrandizement of a week grooms. After the machine tool is installed in the workshop, their technical personnel still can be in our company to wait for two days more, in order to ensure operator can handy ground operates a machine tool. After a few weeks, they needed 3 days of time to our workshop again, work together with our operator, undertake more complex strong voice milling is machined (graph 3) . In addition, sodick company still offerred a phone to seek advice from service and technical support for us, the help solves a few problems that did not think of before us. Since equipment is installed, their technology supports all the time very outstanding. " what the graph shows the electrode that is component of a mould in 3 graphs, it is in final treatment phase, the part that this mould installs final application AA date batteries at production is right the influence of the workshop from the milling machine that purchased Sodick company later, x-Cell company had come true a series of improve. Mr Novel emphasizes saying: "This machine tool raised us further the competitive ability in quote, the quoted price that allows us surpasses the other manufacturer that owns similar treatment facility, before the milling machine that purchases Sodick company, we must become our newspaper price according to the production of manual production methods. This machine tool, the treatment that brought new client and different type for us works. The machine tool is additional flexibility, let us can the market with effectively different open up. Now, we had the capacity that milling of high accuracy figuration machines, and can produce the pattern that the figuration milling that high accuracy asks machines. " to mould production technology character, begin online production when milling machine, after and employee masters his manipulating a technology, the job of the workshop can produce very big change. Mr Novel says: "At present till, its show to produce a field in manual grinding domain and electrode to the body of the biggest impact of the workshop (often also used manual grinder to machine in the past) . Always used the field that grinding machines in the past, or the place that is those our production electrode and EDM treatment, use method of finish machining of strong voice milling now, still maintaining same tolerancepublic errand precision at the same time. In the past, a lot of the mould is medium shaping area must break up many plug-in unit, in order to get used to the productivity that we go. The production of electrode is to use manual grinding device, its grinding machines very tall tolerancepublic errand precision. Many electrode produce treatment on the same area of EDM treatment machine tool also is very average issue. If the spare parts must be machined on EDM, we can use special clamping apparatus, machine on an electrode many ' sampling is counted ' (graph 4) . Now, we can use Sodick milling machine to machine figuration on rolled steel directly, this is very blazing thing, because this does not need,use many plug-in unit and electrode. " the graph is finish machining in 4 graphs the following electrode, contain many comfortable at EDM antrum mould " sampling is counted " , this mould will use at producing connector Mr Novel that uses in a telegraphic industry to complement to say: "Below major case, compare with the production methods photograph in the past, the time that we can see its place is managing is as high as 60% , this basically depends on how many workload can be finished in mounting calorie of operation. Although reducing the circumstance that 10 moulds are versed in or grinding is versed in to fall, we still can achieve similar turnout. " X-Cell company is particularly satisfactory to this purchased milling machine, mr Novel also offerred a few proposals to everybody. He emphasizes: "Ask you to do good homework beforehand, to satisfy the need of your cutting tool, ask the tool supplier clasp with you. Choose in cutting tool respect and use newest respect of processing technique of strong voice milling, they often can offer precious proposal to you. You ought to be remembered well, learn a curve through only, ability begins to win get one's own back. Ability begins to win get one's own back.. CNC Milling
