Introducing the "Tank Cleaning and Filtration Cleaner" for customers using NC lathes and MC lathes, designed to reduce work burden and achieve efficient cutting fluid management.

Are you facing any of these cleaning issues? - Cleaning tasks are cumbersome and labor-intensive, causing back pain. - Prolonged cleaning leads to unpleasant odors. - You have to stop the machines during cleaning, resulting in decreased productivity. - Accumulation of chips leads to unstable processing accuracy and defective products. When chips and sludge accumulate, it can shorten the lifespan of machine tools and increase manufacturing costs. That's where our "Filtration Cleaner" comes in as a solution! The key to the solution is the introduction of a "Filtration Machine"! We have prepared the following two types according to your needs. 1. Large Capacity Open Drum Type (APDQO-F Series) This model is compatible with 200L or 100L open drums. - Reuse of cutting fluid: Efficiently reuse filtered chips. - Improved cleaning efficiency: Significantly reduce work time. - Versatile: Capable of filtering liquids other than cutting machines. - Thorough management: Completely drain liquids to keep the tank clean. 2. Compact Circulation Type (J-F Series) This model is suitable for work in tight spaces. - Maintain production efficiency: Work without stopping the machines. - Space-saving design: Easy to install even in narrow areas. - Continuous maintenance: Regular filtration keeps cutting fluid clean at all times.
