Challenges and Solutions for Processing Fluids
Processing fluid is a liquid that serves to "cool heat" and "reduce friction" during processing such as cutting and grinding. It is also called cutting fluid or coolant fluid.
The use of machining fluid provides benefits such as smooth machine tool operation and improved workpiece quality, but the fluid is a consumable item. If routine maintenance and periodic replacement is neglected, the fluid may gradually deteriorate and lead to unexpected problems.
In this category, we have compiled information on the causes and effects of machining fluid deterioration, ways to reduce maintenance and replacement frequency, and problems caused by chips called grinding sludge. Please check the information to reduce problems and improve quality.
Methods to remove grinding sludge
The fine chips produced by machine tools during the grinding process are called sludge. This sludge continues to be generated throughout the entire time the machine is in operation, and it also gets mixed in the coolant solution. If left unattended, this sludge can cause a variety of adverse effects, such as "deterioration of tool life" and "coolant fluid corrosion. Here, we introduce the negative effects of grinding sludge and how to remove it.

Measures to extend the life of filtration filters
Filtration filters are used to collect and remove sludge and foreign matter generated by grinding and cutting processes. Although their service life varies depending on the product and the environment in which they are used, filtration filters are consumable items. They are not inexpensive, and it is important to extend their life as much as possible, but what efforts should be made to do so? Let's look at some information.

To prevent coolant fluid deterioration
Coolant fluid is responsible for the smooth operation of machine tools and cooling the heat generated. Coolant fluid is constantly circulated to fulfill its role and will eventually deteriorate, but there are ways to prevent this deterioration and reduce the frequency of maintenance and replacement. Here, we summarize the methods and causes of coolant fluid deterioration for your reference.

Coolant filtration system
Three recommendations
Coolant filtration equipment is used to filter sludge generated from equipment. There are a variety of products available depending on the intended use, so it is important to determine "whether the coolant filtration equipment is suitable for the purpose" and "whether the equipment is suited to the characteristics of sludge.
