Instructions for water-soluble cutting oil management process for CNC system: cleaning tank and draining tramp oil, mixing properly “water first – oil later”, controlling concentration – pH – water hardness and periodic maintenance to prevent microorganisms, prolong oil life and maintain stable machining performance.

Instructions for preventing deterioration of water-soluble cutting oils by adding the correct stock solution ratio, maintaining pH and biocide additives, periodic disinfection and mold control, helping to stabilize the oil, keep it odorless, reduce corrosion and maintenance costs.

The article presents a practical example of copper discoloration and sticky cutting oil when using incompatible oils during machining. The cause comes from the reaction between the oil additives and copper ions, discoloring the product and increasing the viscosity of the solution. By switching to a specialized copper cutting oil – which is neutral, stable and does not react with non-ferrous metals – this phenomenon is completely overcome. The result is a shiny product, stable oil color, reduced oil change frequency and cleaning work, and improved production efficiency.

Foaming in water-based cutting oil is a common problem in CNC metalworking, turning, milling, grinding, etc. Foam not only causes the solution tank to overflow but also reduces the efficiency of lubrication, cooling and chip washing, affecting the machining quality and tool life. This article analyzes common causes and introduces technical solutions to effectively reduce foam, ensuring stable operation and high productivity.

Water-soluble cutting fluids in CNC systems can easily develop unpleasant odors if not properly managed. Causes include microbial contamination, tramp oil, poor fluid maintenance, unfavorable environmental conditions, substandard water quality, unstable concentration and pH, as well as insufficient or depleted biocides. This article analyzes the mechanisms and consequences of each cause and provides preventive solutions to help businesses extend fluid life, protect worker health, and maintain machining performance.

A turbocharger is a device that uses exhaust gas energy to compress air into the engine, thereby increasing the oxygen supply for combustion. This allows the engine to achieve greater power, improved fuel efficiency, and reduced emissions. The main components of a turbocharger include the compressor wheel, turbine wheel, center shaft, compressor housing, turbine housing, oil supply system, and air intake duct. It is an advanced engineering solution that makes modern engines both powerful and environmentally friendly.
