1K. Contain in the machine tool temperature controller, in disconnect when moving, with machine tool of external temperature refrigeration. Such, machining center must shutdown, till whole equipment restores the temperature to stability. This company is undertaking nicety machines production initial stage, sunshine arrives through producing the shutter illuminate of the workshop on the machine tool, illumination temperature also can make workpiece generation extends a gender. Now, this kind of state has been turned round. If this company still presses DIN of German industry standard to undertake machining production up to now, do not have the business so early. Current, the permission that this company treatment makes tolerancepublic errand limits is 2~3 μ M, this is to bore hole not only the standard of exercise, also be the standard that workpiece outline grinding works. The machine tool that place of company of Helmut Wandinger of measurement unit of blame contact laser uses all uses what Blum-Novotest company develops to be used at adjusting the laser measurement unit of cutting tool. Previously, the member machine a person of this company is to use cutting tool of tape measure manual adjustment, but even if slight contact, also can produce an effect to bit, or be touch razor blade rupture. So, this company cited very quickly laser adjusts cutting tool device. 1997, this company applied this kind of laser to adjust cutting tool device on the machine tool that Chiron company provides, at the beginning of this one device is being used, got admissive. Because laser is measured,accuse device to decorate the exercise spot in machining center, accordingly, must execute protection to this instrument. For this, blum-Novotest company took a series of safeguard: When the machine tool undertakes cutting works, use a mechanical lock to shut device to protect its, before this instrument pass in and out, the lock shuts device to aerate with the piston means undertakes moving protective. When this instrument is in open condition, machine tool be deceived sheds concussion, the meeting such as the dig bits that machines generation affects operation. Undertake in this instrument cutting tool is adjusted when measuring, will be protected air current to wait for dirty content in order to avoid treatment dig bit by type. These dirty content may include centrifugal cast the machine tool cooling fluid that go out, accordingly, undertake to telescope protection is an on the safe side spends very expensive program. Graph 3 measure cutting tool through be on the machine tool, make precision achieves technical limit Nextpage and photographs of other laser measurement unit to compare, the laser ray that the Blum laser of Blum-Novotest company measures measuring implement to give out is paper-thin, its ply is a few micron only, and focusing performance is stronger. The laser ray that some laser measure measuring implement to give out not focusing, ray ply is bigger also. Such, measurement unit often can want when measuring cutting tool length " estimation " , can identify broach more thickly. If use these wrong measured value to undertake workpiece is machined, the aperture that reachs will be less than a requirement to be worth. If the cutting tool of the machine tool is measured,have by accident, once broach is decorated,go up in workpiece, the main shaft of the machine tool can enter fast archives roll. Clearly, the length of workpiece will appear error, bring about the generation of a series of reject. The electronic product with a series of extremely expensive efficiency that Blum-Novotest company manufactures is called " NT-Technologie " . Use device of this kind of electron to be able to undertake be metricaled quickly, every have cutting tool cut, this device undertakes detecting, even if subtle cut blemish and wear away to also can be monitored. Its use this device " Plausibilitaet " the law that monitor and daggle are measured, can make its do not suffer the effect of machine tool cooling fluid, ground of on the safe side undertakes monitoring. All MicroCompact NT of Helmut Wandinger company measurement unit that all used Blum-Novotest firm with Nano NT machine tool. These measurement unit still can pass the distance commutation between illuminant and receiver, will measure the cutting tool with calm measurement bigger standards. Graph in the 4 machining center that are in Helmut Wandinger company, with laser measurement unit can measure the smallest cutting tool. The cutting tool in the graph is a diameter the use with the mainest to the measurement unit of the company of the Blum-Novotest that monitor of cutter arbor broach of miniature of 20 × D of 50 μ M is to use cutting tool of the machine tool that monitor. Between the two treatment exercise of the machine tool, no matter whether bit is whole, cutter arbor will undertake monitoring. The broach of norms of 100 μ M is machining 30000r/min of turn up of the arbor when exercise, it is a faint resonance merely right now, if appear the eccentric throw of M of a 2 μ , cause cutting tool likely break off. This shows, laser monitoring and warning device ruptures in monitoring cutting tool the respect is what kind important. When undertaking processing work, the staff member of Helmut Wandinger company can discover such circumstance sometimes -- the effect that cutting tool suffers some kind of element becomes " black Brown " . For example a broach, if become completely black Brown continue to work even, the most serious consequence that will cause likely is, follow-up cutting tool breaks off entirely, cost of it may be said is heavy. Accordingly, although wait for the aperture of treatment to remain only, the broach that break off also cannot be used constrainedly, pair of cutting tool also cannot ignore below this kind of circumstance monitor. Limits is in the cutting tool unit price of high delicacy commonly 25~180 euro, the part is as high as 250 euro. Conference action reachs cutting tool and the power that workpiece collision place produces on arbor, what this also can cause finished cost is elevatory. Accordingly, of arbor material choose as much very important. Graph the 5 quality to can evaluate treatment, helmut Wandinger company purchased microscope of grating electron miniature, direct installation is processing a place the measurement unit of two Kong Jiguang that can see on vacuum straw treatment goes out in the graph, direct installation is below ideal situation the stage is secured in workpiece by, such, laser measurement unit but will all element, if machine tool component is in,temperature affects next occurrence to extend wait to undertake monitoring along with all the others. If arbor and be heated of cutting tool fastener appear,extend, the displacement deviation that arbor appears below rotate speed influence, will get compensating along with all the others. In treatment accuracy is in micron limits inside when, such monitoring with compensation cannot oversight. Monitor can machining exercise spot to undertake only, roll of the arbor that monitor slants place a condition, before processing work sometimes, measure broach even, the serious consequence that place of dimension of mount mark wrong broach causes is wrapped in order to prevent a supplier in the product. Undertake metrical mattering to finished cost directly to cutting tool. If Helmut Wandinger company once wanted,on a workpiece treatment gives opening of 960 tiny body. When treatment, the feed rate of arbor of requirement machine tool is 1.
5mm/min, use high gear namely. And if use high gear to undertake machining, machining a Kong Shi, cutting tool still does not have workpiece of bring into contact with, had gotten 4s for nothing. Can imagine, if finish the treatment of these 960 aperture to work, so machine tool " get for nothing " time is as long as a many hour. Here the circumstance falls, the measurement unit talent that can use Blum-Novotest firm only assures to machine precision achieve a few micron. Can assure to be when use high gear, cutting tool sails the distance to workpiece surface is shorter. Can save a lot of handling time so, improve manufacturing beneficial result thereby. Blum laser is measured accuse device to make machine precision to amount to technical limit to go up to undertake be metricaled directly to cutting tool in the machine tool through using laser measurement unit, can make machine precision to reach technical limit. To monitor work, be in early 2004, helmut Wandinger company purchased electron microscope of a grating (graph 5) . And the groovy measurement technique that uses a convention cannot undertake monitoring. Can use Blum-Novotest firm only without contact and the measurement unit with extremely tall precision, ability makes measure a result be in permit tolerancepublic errand range inside. In addition, about detecting the hard usage sex of equipment, still need to consider how to make measurement unit is machining the spot not to suffer the effect that dig bits and lube splatter. Accordingly, the laser that machines manufacturing company majority to all use Blum-Novotest firm is measured charge unit. CNC Milling
