Изобретение относитс к области абразивной обработки, в частности, к методам определени величины износа алмазных, эльборовых доводоч ных шлифовальных кругов, обеспечивающих 10-114 класс чистоты поверхности .The invention relates to the field of abrasive machining, in particular, to methods for determining the amount of wear of diamond, elbor finishing grinding wheels, providing a 10-114 grade surface finish.
Известны способы испытани шлифовальных кругов, заключающиес в определении их удельного износа посредством сравнени расхода круга к съему обра батываемого материала .Methods are known for testing grinding wheels which consist in determining their specific wear by comparing the flow rate of a wheel to the removal of the material being processed.
Цель изобретени - повышение точности результатов испытаний кругов при доводочном шл.ифовании и уменьшение времени испытаний .The purpose of the invention is to improve the accuracy of the test results of the circles during the finishing cycle and to reduce the test time.
Дл этого одновременно измер ют изменение радиуса образца и величины микроподачи шлифовального круга, а износ а-бразивных зерен определ ют как разность величины микрододачи и размера образца.To do this, a change in the sample radius and the microfilter value of the grinding wheel is simultaneously measured, and the wear of the a-brazivic grains is determined as the difference between the microdot amount and the sample size.
Изобретение по сн етс схемой.The invention is illustrated by the scheme.
Алмазный круг перед испытанием находитс в положении 1, а после его микроподачи на величину Л - в положении 2. Деталь перед испытанием находитс в положении 3, а после съема материала по радиусу на величину Б- в положении 4.The diamond wheel before the test is in position 1, and after its micro-feed by the value of L is in position 2. The part before the test is in position 3, and after removing the material along the radius by the value of B- in position 4.
Измер ют дишь изменение радиуса детали на величину Б, а изменение радиуса круга наThe change in the radius of the part by the value B is measured, and the change in the radius of the circle by
величину В определ ют как разность между величиной А микроподачи и изменением радиуса детали, т. е. В А-Б.The value B is defined as the difference between the magnitude A of the micro-feed and the change in the radius of the part, i.e. B AB.
Изобретение может быть использовано 5 только дл кругов с ограниченным пер.иодом стойкости, дл условш доводочного шлифовани с малой периодической или непрерывной (1,5 мкм/мин подачей на глубину с использованием шлифовальных станков ЗЕ112The invention can be used only 5 for wheels with a limited peri-dability of durability, for conditional finishing grinding with a small periodic or continuous (1.5 µm / min feed to the depth using the grinding machines EN112
0 и других, жесткость шлифовальных бабок которых составл ет 5-.10 кгс/мкм, а микроподача осуществл етс с посто нным радиальным усилием 3-10 кгс, что обеспечиваетс , например, соответствующим подбором скорости микроиодачи или подпружиненным поджимом круга к обрабатываемой поверхности.0 and others, the rigidity of the grinding heads of which is 5 -10 kgf / μm, and the microfilming is carried out with a constant radial force of 3-10 kgf, which is ensured, for example, by appropriately adjusting the micro-id rate or spring-loaded pressure of the wheel to the surface to be treated.
Иредмет изобретени Iredmet invention
0 Способ испытани шлифовальных кругов, заключающийс в измерении величины износа круга, отличающийс тем, что, с целью повышени точности результатов испытаний кругов при доводочном шлифова-нии, уменьшени времени испытаний, одновременно измер ют изменение радиуса образца и величины микроподачи круга, а износ абразивных зерен определ ют как разность величины микроподачи и размера образца.0 A method of testing grinding wheels, consisting in measuring the amount of wheel wear, characterized in that, in order to improve the accuracy of the test results of wheels during finishing grinding, reducing test time, the change in the sample radius and the micro feed rate of the wheel and the wear of abrasive grains are simultaneously measured defined as the difference in the micro feed and sample size.
