What are the requirements for selecting specialized fluids for large CNC machining centers

The selection of specialized fluids for large CNC machining centers mainly focuses on their rust resistance. Generally, their lubricity and cleaning performance can meet the requirements. However, the machinery and equipment of CNC machining centers are generally expensive, so a specialized fluid with good rust and corrosion resistance should be selected to meet the requirements of machining machine parts. At the same time, it is also necessary to protect the various material components and paint surfaces of the equipment.
When selecting a specialized solution, the following steps are generally required:

1. Choose the type of specialized fluid: that is, choose oil-based cutting fluid or water-based cutting fluid. The main factors to consider are workpiece material, machining quality requirements (machining accuracy and surface integrity), tool material, machine condition, machining method, cutting amount, etc.

2. Choose the type of specialized liquid: It is necessary to comprehensively consider the processing performance, physicochemical performance, and environmental sanitation performance of the specialized liquid to decide which type of product to choose. This process is mainly based on the decision-maker's understanding of the processing environment and basic knowledge of specialized fluids. Of course, commercial factors such as the credibility, supply capacity, and technical services of specialized liquid production enterprises also need to be considered.

3. Conduct environmental and physicochemical performance tests on the pre selected specialized liquid products.

4. Conduct actual cutting experiments on specialized fluids with qualified environmental and physicochemical properties to evaluate their machining efficiency.

5. Trial use the varieties that have passed the above testing and testing, and make an economic evaluation based on the trial use. Generally speaking, it takes a long period of trial (at least one liquid cycle) to reach a conclusion.
