At present, the common golden yellow, cobalt copper, black and other drill bits, milling cutters, molds, etc., these appliances are coating tools processed by coating technology. Coated carbide inserts can be used to extend tool life and meet special applications, and different colors on the tool mean different coatings.
Causes of leak detection in coating machine:The coating machine needs to work in a high vacuum environment, and the quality of the vacuum directly affects the quality of the coating. Sometimes the vacuum of the coating machine cannot be pumped down or the vacuum degree is not good, which may be due to loose joints or false welds in some welds. Traditional leak detection methods require the coater to shut down, fill with nitrogen, and then apply soap bubbles to the suspected leaks, which is time-consuming, laborious and easy to misjudge, and cannot detect subtle leaks.
Shanghai Bodong** Pfeiffer helium mass spectrometry leak detector uses helium as tracer gas, the minimum leakage rate is less than 5e-13 pa m3 s, safe and environmentally friendly, no need to stop during leak detection, and the leak detector can be quickly and efficiently completed by directly connecting to the leak detector in the bypass of the vacuum pump.
Shanghai Bodong tool coating leak detection customer case: A customer introduced a PLATIT coater with a molecular pump Hipace 1500 and a rotary vane pump Duo 35 for tool coating, compared with a competitor, the Pfeiffer vacuum pump achieves a higher and stable vacuum level in a shorter time.
Leak detection method of coating machine: using vacuum method for leak detection, the coating machine does not need to be stopped, and the leak detection can be completed by directly using bellows to access the leak detector in the bypass of the vacuum pump, and spraying helium in the suspected leakage.
