You ever were a kind of new use, affirmatory and best grinder and grind provide and had hurt head, because you want to be mixed with grinder,grind provided supply grinding of first-rate of manufacturer discussion decision and feed speed, you should groom well operation personnel. However, your quality after beginning day of labour be valid or number week controls administrator to tell you, this new machine tool cannot machine the part that gives qualification, you must be identified and fix problem place at the appointed time, find out all sorts of variable that affect grinding process, this is not an easy thing. To prevent this kind of situation, more and more manufactories change direction to undertake metrical in grinding treatment process, this measures the strategy to be called " online measure " , because it is the dimension in spare parts of the monitoring when the spare parts is machined. Although be at the beginning of 50 times,already process of this kind of closed circuit controls a method, be in only however in recent years, as a result of online the aggrandizement that measures systematic function, durable make the choice with actual workshop with handy ability. Online measure use door can: Control grinding craft; After emery wheel nap, the machine tool can be answered quickly " 0 " ; According to spare parts dimension, adjust cycle immediately; Obtain real time to feedback to be analysed in order to accelerate the processing of breakdown problem and craft. Because the spare parts is measured, be in real time undertake compensating on the foundation, what grinding machines is online measure do not need statistic to dog. The effective control of the machine tool relies on all sorts of conditions when every spare parts is machined. In application, measure a head must sturdy, can bear to be exposed for long taking abrasive and the cooling fluid that worry bit in. Sturdy asks necessarily simple. Say commonly, simple measurement the instrument has better thermal stability, at the same time the spare parts of the measuring instrument counts less better maintenance, maintenance is faster also. "Had jumped over simplier " the interface that the principle also applies to a measuring instrument, it should be to height can be inspected gender and have icon, so that fast installation is mixed,reduce handlers to produce wrong opportunity. Additional, wanting the spare parts face that wear often is spiccato, survey a system must can accurate measurement its are true dimension, include to measuring an area even inside intermittent halfway dimension. The error of the spare parts asks to achieve 3 μ M to be not infrequent, with online the use that measured gets result to prove it. Attention, a kind double point to / the grinder measuring instrument of double sensor can achieve highest measurement in whole process precision, and because it can make you see every sensor respectively, also can use as so craft analysis. When operation personnel sees the measuring instrument is fluctuant, he is wrong perhaps think to measure appearance to have a problem, in fact this wave motion may is the first sign that craft puts in certain problem. For example, if material cutting rate falls slowly, this shows emery wheel needs to amend, measuring medium wave motion to make clear possibly also is problem of spare parts metabolic, this increases support of a center again with respect to need, reduce emery wheel pressure or with emery wheel of different adjustment in direction. Adopt surveillance and correction grinding technology, online measure the inchoate level that can producing to remove quality issue, is not production goes out abandon checking level assembling level to just discover a problem even, such you won't make waste product. Make your quality makes sure cost had materiality to drop thereby, this is weighed call " quality lever " concept. Altogether, "Quality lever " the concept is aborning be amended earlier or improve quality, certain technology and the benefit that reduce cost are greater. Producing the final phase of the process, want when the product namely when shipment gives an user, quality defines in this phase problem criterion fee is very big, more groovy is at this moment unalterable already craft will avoid recurrent problem. The circumstance is different, from theoretic say the initiative level that producing a course namely product technology plans stage, the investment redound that goes up in quality at this moment compares with the photograph when delivering goods to the product will be 100: 1. Producing project level (machine level in the metal namely) , the investment income ratio on the control of closed circuit process that is a foundation with module is measured or be being explored is controlled in quality later (QC) or examination phase will improve should count greatly decuple. If you want when assembling level to be improved again, will not have investment redound but character. "Quality lever " demonstrate earlier in producing a course certain quality clearly problem criterion benefit is greater, cost is lower, the time that you wait for is longer, profit is smaller, cost is bigger. You would rather be used in the advanced position that produces a course online measure, and going up downstream use, collect in order to to improve quality downstream not only very beautiful money, and should correct flaw, already was helpless even.
