What is the difference between the methods for measuring the tapping torque performance of cutting fluids?
December 01, 2022
Nowadays, there is no effective, simple and fast simulation method to determine the performance of cutting lubricants, except for experiments in actual work. In China, the four ball machine PB is mainly used as the evaluation index of cutting lubrication, but the materials of the four ball machine and the cutting friction pair are very different, so the four ball machine cannot accurately reflect the lubrication in the cutting process. Now some enterprises have developed a simple, convenient, fast and easy to operate tapping torque testing device. The measuring cost and expense of this device are very low, and each experiment takes only a few minutes to draw conclusions, so it is very fast. The error of the measurement result is within 3.0%. Compared with the PB value of the four ball machine and the wear diameter method, the simple measurement method of cutting lubricant is closer to the fact, which is consistent with the empirical results accumulated in practice.
Typical application of cutting fluid tapping torque test: 1. Experimental study on the application of water-soluble antiwear agent in water-based cutting fluid 2. Research on torque model of vibration tapping based on BP neural network 3. Development of multifunctional and long-acting extreme pressure emulsion cutting fluid 4. Research on cutting fluid effect in titanium alloy vibration tapping 5. Study on the performance of paraffin based and naphthenic Base Oil compounded emulsion cutting fluid 6. Tapping torque test system (lubricating medium contrast tester) 7. Used to verify and test the tap performance and the actual efficacy of the knife shell coating 8. Match the most suitable lubricating medium for specific tools and processing materials Core functions: R&D: develop new product formula of lubricating medium through comparative test; Preferential: used for coating taps and tools to improve the process and achieve the best performance products; Optimization: Continuously improve product performance, far overload competitors, and improve customer loyalty.
Significant advantages: 1. Precision: machining system and data acquisition system with aviation level precision can dynamically obtain accurate torque; 2. Intelligence: intelligent analysis, calculation and chart generation; 3. High repetition precision: small numerical fluctuation and stable figure; 4. Strong applicability: less dependence on the environment.
