In the metal processing industry, cutting fluid, as a key auxiliary material, plays a vital role in processing accuracy, tool life and workpiece quality. However, when processing aluminum and non-ferrous metals, improper use of cutting fluid often leads to oxidation and discoloration of the workpiece, seriously affecting product quality.How to solve the problem of oxidation discoloration of workpieces processed by cutting fluid
1. Choose the right cutting fluid: Choose a cutting fluid with excellent antioxidant properties according to the processing materials (such as aluminum and non-ferrous metals) and processing requirements.
2. Regularly test and adjust the pH value: Use instruments such as an acidometer to regularly test the pH value of the cutting fluid to ensure that it is within the normal range (6.5-8.5). If the pH value is found to be high or low, add an appropriate amount of regulator in time to adjust it.
3. Strengthen the cleaning and maintenance of the cutting fluid: Regularly replace the cutting fluid and keep the water tank and cutting fluid clean. Additives with antibacterial properties can be used to extend the service life of the cutting fluid.
4. Stabilize the cutting fluid formula system: Choose a cutting fluid formula that has been optimized to ensure that it can maintain stable performance under various working conditions. At the same time, pay attention to the compatibility of the various components of the cutting fluid.
5. Ensure that the cutting fluid contains sufficient aluminum slow-release agent: When selecting a cutting fluid, pay attention to whether it contains enough aluminum slow-release agent and keep its content stable during use.
6. Regularly test the concentration and pH value of the cutting fluid: Use instruments such as refractometers to regularly test the concentration and pH value of the cutting fluid, and add new fluid or adjust the pH value in a timely manner according to the test results.
The implementation of the above measures can effectively solve the problem of oxidation and discoloration of aluminum and non-ferrous metal workpieces caused by the use of cutting fluid, and improve processing accuracy and product quality.
