Solve these seven problems, and your cutting and grinding fluid will be more effective!

The use of cutting and grinding fluid has a great impact on tool life and machining quality. Even the best cutting and grinding fluid cannot play its due role if it cannot be effectively transported to the cutting area. The advantage of proper use of cutting and grinding fluid is to effectively remove chips, which also helps to prolong the tool life. If the nozzle of cutting fluid is properly placed, the chip removal groove of milling cutter and drill bit can be prevented from being blocked or blocked by chips. For the processing of some large workpieces, or the powerful cutting and grinding with large feed, two or more rows of coolant nozzles are used to make them fully cooled, which is conducive to improving the processing efficiency and ensuring the processing quality.
Seven problems in the use and maintenance of cutting grinding fluid 1. Directly add water - the cutting fluid concentration is too low Reduction of cutting fluid concentration Rust on machined parts 2. Add concentrate at will - the concentration of cutting fluid is too high skin sensibility Foam is too big Too clean 3. The machine tool leaks oil - there is a large amount of oil floating in the cutting fluid Rapid propagation of bacteria PH value reduction The machined parts are rusted Unbalance of cutting fluid 4. The flow is too large or the pump intake - cutting fluid produces a lot of foam Poor cooling Reduced machining accuracy 5. Long-time shutdown - bacteria multiply PH value reduction The machined parts are rusted Machine tool guide rail rusted 6. Poor grounding of the machine tool - large area of rust on the machined parts Large-area corrosion of machine tool guide rail 7. High water quality - high calcium and magnesium ion content Soap precipitation occurs in cutting fluid The machined parts are rusted
Methods to prolong the service life of cutting grinding fluid 1. Install an automatic air mixer in the metalworking fluid tank to stir continuously and slowly, so as to make the metalworking fluid fully contact with the air. 2. On the rest day, ensure at least 2 hours of internal circulation of cutting fluid. 3. Timely remove the foreign oil in the cutting pool, as well as the slag, grinding debris and mud. 4. It is not allowed to throw cigarette butts and dirt into the cutting pool. 5. Arrange special personnel to be engaged in the detection of cutting fluid, and timely handle problems found.
