本文简单地介绍了英国OMT公司在电火花加工机床上加工气动塞规喷嘴孔及逸气槽的情况。这种方法的加工精度及效率都较高,并且还可以方便地用于加工气动规塞上的矩形孔。——编者英国OMT公司生产的OMT-Etamic量仪是一种薄膜式高压气动量仪,并且是通过指示表读数。高压空气以恒定的音速通过确定膜片位置的针形阀,而膜片则构成气动测量系统的所谓气动桥路。该量仪没有采用稳压器和压力表,并且可以测量出小达0.000006吋(0.14微
This article briefly introduces the UK OMT company in the EDM machining pneumatic plug gauge nozzle hole and gas tank situation. This method of processing accuracy and efficiency are high, and can also be easily used for processing the rectangular hole on the pneumatic gauge plug. - Editor OMT OMT company produced the British OMT gauge is a thin-film high-pressure pneumatic instrument, and through the indicator readings. The high-pressure air passes at a constant speed of sound through a needle valve which determines the position of the diaphragm, while the diaphragm forms the so-called pneumatic bridge of the pneumatic measuring system. The gauge does not use regulators and pressure gauges, and can measure as small as 0.000006 inches (0.14 micro
