Depend on the precision of cutting cutting tool the precision of the emery wheel that produces it. Accordingly, the workshop of production cutting cutting tool, must accurate ground is corrective the appearance with nap emery wheel, so that production gives consistent high accuracy cutting tool, satisfy the client's more and more accurate spare parts requirement. The emery wheel of workshop tool grinding machine is corrective can use with nap online or system leaving a line, every kinds of system has its advantage and drawback each. Those who leave line nap is special and corrective with nap machine tool be independence, because this leaves line nap not cloggy,grinding is operated. These machine tools get used to whole emery wheel package, they serve at a lot of station grinding machine inside same workshop. The fragment that can make nap place arises maintains it is beyond accurate grinder. "The grinding machine that workshop of most cutting cutting tool uses our system to serve stage or 10 above " , the Bill Freese of Rush Machinery company says. Rush Machinery is one is made corrective the company with nap machine tool. Use the workshop of these machine tools, use form of two emery wheel, an emery wheel works normally, at the same time from grinder trade emery wheel unit automatically, debus component of each tatty emery wheel, corrective with nap these component, install them again trade emery wheel unit. The emery wheel function that grinds cutting tool depends on corrective the workshop that grinds cutting cutting tool to weighing from line nap machine tool with nap is particularly advantageous. After these workshops have the treatment of short time normally, undertake emery wheel changes often, and before system leaving a line can make sure emery wheel component is changing, can get ready, and the machine tool need not await. If tool workshop undertakes mass-produced, it uses component of two emery wheel normally, freese says. When component of an emery wheel works, handlers is corrective on a machine tool leaving a line with nap another component. Emery wheel is covered in join on poise, nap machine puts store afresh diameter of every emery wheel is opposite the relative value at another emery wheel diameters in this component. The hand of Ruch moves system leaving a line to have 3 class: The 1st kind is basic model, the workshop basically is used at dish form emery wheel or angle emery wheel. The video optics system that the 2nd kind of machine tool has height to spend enlarge optics camera lens and video camera. Workshop according to show all sorts of circle pattern plate on machine tool screen come radius of nap emery wheel. Great majority of the 3rd kind of machine tool is commonly used at workshop of cutting cutting tool, of video system, contain the video camera that magnifies highly and computer, moving CAD (CAD) program, many graphs layer shows on screen. Use the workshop of the 3rd kind of machine tool, can produce the combination of any radius and angle, can produce a needs emery wheel outline. What the machine tool of this grade accelerated outline of complex emery wheel is corrective with nap, be like the circumstance of grinding broach, freese says. Design of online nap system works with the grinding that nobody attend to between Yu Changshi, because outfit of this kind of system is inside grinder, move automatically. This kind of system offers nap of CNC pilot tall nicety. "I always can be recommended online and corrective with nap, the actual arbor of the grinding machine that because this system is right,basically using and main shaft are corrective with nap emery wheel, " holy dagger class (Tim Finn of engineer of application of advanced cooperation of Saint-Gobain Abrasives) company says. Because recent technology progresses,he says so is, make the workshop can use diamond nap roller, emery wheel of online nap diamond, improved online nap technology. Leave a line corrective to carry package of emery wheel of the knife that grind a knife with nap system continuous working diamond emery wheel offerred very tall metal purify to lead, the production that reduced a hardware greatly is periodic. This kind of emery wheel is durable, need very few rehabilitate and very few machine tool motivation to move. But because emery wheel is not easy grinding, and preserve its original shape, so workshop cannot effectively online nap these emery wheel. And cannot offer enough rate as a result of the main shaft of online nap device, diamond nap roller wears away very quickly. But, 3 kinds of of holy dagger class new products: Cutting of Unival G-Force diamond annulus, MaxTorq nap device and cupreous outline roller, improved diamond emery wheel the technology of online nap. The diamond emery wheel that Unival G-Force cuts easily, do not need marvellous prune after figuration or use diamond roller nap. Marvellous nap is additional craft, it can expose the cutting abrasive that gives emery wheel, should be when the hard colophony binder emery wheel like treatment rock very be necessary. The emery wheel of this kind of type, used at workshop grinding high-speed steel and hard alloy cutting tool in the past. Finn says, colophony felt emery wheel will cannot use at cutting, unless be in corrective hind the nap that use a stick. The G-Force emery wheel of his company is to mix get together acyl inferior amine metal felt. Make them easy the binder that the reason of cutting is them is especially strong, emery wheel does not need a lot of. With emery wheel of diamond of nap of diamond nap roller, need high rate, and heretofore, main shaft of online nap roller with 3, 600r/min moves, can't be competent this job. The MaxTorq of Dan Shengge class builds entire plant, do not have through dc brush electric machinery, offer main shaft speed to amount to 12, 000r/min, make the workshop uses 150mm(6 inch) when diametical nap roller, nap emery wheel can be achieved 5, 500m/min(18, the speed of 000sft/min) . Finn says, through high-speed nap main shaft is mixed decelerate emery wheel speed to arrive cutting of 1000 minutely surfaces foot, the workshop is OK economic ground is corrective diamond emery wheel. But new abrasive must be exposed go up in emery wheel, otherwise they will cannot cutting. To make sure new abrasive is exposed, holy dagger class developed cupreous outline roller, its characteristic is round of week diamond grain wide it is on average 0.
250 inches. Although most workshop uses rate with nap horizontal stroke (nap roller is across the rate of emery wheel) the yield measurement that is nap craft. Namely emery wheel every turn the horizontal stroke uses the measurement of rate -- nap roller " hit " emery wheel is apparently arenaceous the number rate of makings, finn says. Rate of good one on top of another is, any more frequencies, mean nap roller to hit bit samer number in classics of the Si on emery wheel, than it must the frequency is more. For example, jackknife is led 10 mean before proceed, nap roller hits the diamond grain of emery wheel 10 times in same point. "The key that uses diamond nap diamond is to use thin roller, as soon as possible across emery wheel. " Finn says. The roller of cupreous solder outline of holy dagger class does not need new and abrade, restore appearance of their most advanced geometry. This is crucial, because the machine tool omited to grind to abrasion is divided and install relevant stop production time, finn says. With traditional roller, workshop in roller in life period, must new and abrade 4, every time the 30-50% that charge needs price of a new roller. In Luo Man watchful is overcome (Rollomatic) , hold high division (Anca Inc.
) with Waerte grinding (Walter Grinders) checks a process to the spot of these 3 kinds of products of tool grinding machine in, turn diamond emery wheel with carbonization contented, the diamond roller nap that moves with high speed the chamfer on the toggle on cutting tool of the whorl of carbonization milling cutter, rough machining and knife of high-speed steel Duan Xi and toggle. In most example, the treatment cycle of the spare parts decreases 30% , every time the crop of the spare parts after emery wheel nap times add. And before this, these test workshops use colophony binder emery wheel, emery wheel must come down from the discharge on grinder, in the nap on the machine tool that leaves a line.
