What is the reason for the peculiar smell when the machining center uses cutting fluid to cut at high temperature? There are many machining centers that often encounter such problems when using cutting fluid. They say that there is often a choking smell when using cutting fluid. What is the reason? Under normal circumstances, the contact between the workpiece and the tool produces high temperatures. One of the functions of cutting fluid is cooling. Under the action of the cutting fluid, the temperature of the workpiece decreases, and there will be a little smell at this time, but it should not be very large, and it should not be pungent.
In view of the fact that many cutting fluid products are organic components at present, it will cause peculiar smell, and there will be a choking smell at this time. This is a sign that the cutting fluid begins to deteriorate, and it is recommended to replace the cutting fluid after testing. There are three main reasons why the cutting fluid emits a choking odor during high temperature cutting: 1. At high temperature, the active element will precipitate in the original stable group and may vaporize, so this is the reason for the smell. 2. The extreme pressure elements, phosphorus and sulfur in the cutting fluid, especially when the active sulfur is at high temperature, it is easy to precipitate sulfur and release it with the stimulating taste of hydrogen sulfide. It indicates that the sulfur in the additive is unstable or too much, and the additive should be replaced. 3. A small part may be the volatilization of the coupling solvent in the cutting fluid, but it will not be particularly irritating, and the sulfur may be larger. Cutting fluid is a kind of working fluid used for cooling and lubricating tools and workpieces in the process of metal cutting and grinding. Cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute.
