Description
The production process of medical hypodermic needles is relatively simple in the early days, wire cutting and electrolytic grinding were used, and the grinding efficiency was low. Because there is no suitable hypodermic needle cutting wheel, this process has been used for a long time.
Hollow thin steel tube is very sensitive to temperature, it will be blackened (blue, black) even slightly higher, so when the grinding wheel working, it can not produce too much grinding heat, or pass a lot during grinding The water-based coolant should be removed in time. The general resin grinding wheel has poor water resistance and the strength cannot be guaranteed. In the past, only the copper powder conductive grinding wheel with a high density was used. Now, through product development, the water resistance of the resin grinding wheel has been solved, and these problems have been solved.
The current needle cutting process is: first cut the hollow thin steel pipe with a 0.5mm resin slice according to the specified length (water cutting), put it in the rolling throwing machine to remove the burr, rinse it, and then grind it out with a coarse grinding wheel after loading and unloading. Beveled, and finally chamfered with a fine grinding wheel. The entire process is also a few minutes, and the grinding efficiency is quite high. The key to the manufacture of grinding wheels is not too hard, otherwise the self-sharpness is not good. Even if it is cooled by water, there is still a large amount of grinding heat that cannot be discharged. Second, it should not be too soft, too soft, not only the needle size retention is not good, but also the grinding wheel is easy to burst, and there is a personal accident.
Our hypodermic needle cutting wheel especially designed for injection needles, as well as watch parts, exhaust catalyst tube, stainless steel or non-ferrous materials, working speed up to 60m/s. the finished parts are precision and free of burrs.
