The selection of cutting fluid is a key link that affects efficiency, quality and cost in mechanical processing. It is necessary to take into account the core requirements of the processing technology and the characteristics of the materials. This article will provide specific selection criteria and recommended solutions from multiple aspects such as processing technology classification and material characteristics to help achieve precise adaptation.
01
Processing technology adaptation
High-speed cutting: such as high-speed milling and turning, synthetic cutting fluid is preferred because it is composed of water-soluble additives, has excellent cooling performance, can quickly take away heat, and prevent tool overheating and wear and workpiece deformation.
Medium and low-speed cutting: such as ordinary turning, milling, and drilling, semi-synthetic cutting fluid is more suitable, balancing the cooling and lubrication requirements.
Heavy-load cutting: such as broaching and tapping, the pressure between the tool and the workpiece is high and the friction is severe. Semi-synthetic cutting fluid or emulsion containing special lubricating additives (such as extreme pressure additives) is required to reduce cutting force and tool wear.
Light-load cutting: such as simple plane milling and drilling, ordinary semi-synthetic or synthetic cutting fluid can meet the needs.
High-precision machining: For precision turning and grinding, synthetic cutting fluid or high-quality semi-synthetic cutting fluid should be used to ensure machining accuracy and surface quality.
02
Material adaptation
Ferrous metals: For example, steel and cast iron, emulsion, semi-synthetic or synthetic cutting fluid can be used, but attention should be paid to rust prevention. If the workpiece needs to be stored for a long time, it is recommended to choose semi-synthetic or synthetic cutting fluid containing high-efficiency rust inhibitor.
Non-ferrous metals: For example, aluminum and copper, which are sensitive to corrosion, water-based cutting fluids designed specifically for non-ferrous metals should be used to avoid surface discoloration or corrosion.
Stainless steel: It has a high tendency to work hardening and high cutting force, so semi-synthetic or synthetic cutting fluids containing special lubricating additives (such as sulfur and chlorine extreme pressure additives) should be used.
03
Tool characteristic adaptation
High-speed steel tools: Poor heat resistance, easy to lose hardness at high temperatures, and require cutting fluids with good cooling performance. Use water-based cutting fluids for high-speed rough cutting; use oil-based cutting fluids or high-concentration emulsions for medium and low-speed finishing to reduce friction and adhesion and inhibit the formation of cutting nodules.
Carbide cutting tools: good red hardness, but expensive, dry cutting is not economical. Generally, oil-based cutting fluids containing anti-wear additives are selected, and the tool needs to be evenly cooled to avoid sudden cooling and chipping. When cutting at high speed, a large flow of cutting fluid can be used to spray the cutting area.
Chorus fully synthetic cutting fluids are made of water-soluble plant polyesters, lubricants, rust inhibitors and other additives. They have excellent cooling, lubrication and cleaning properties, and are formulated according to different process requirements of customers. It provides strong extreme pressure lubrication performance, and the oil-free formula combines cutting and grinding to ensure tool cooling and clean processing environment. It has excellent performance even in extremely harsh processing. During the workpiece processing, it effectively avoids the problem of working fluid odor. The comprehensive cost is lower than that of microemulsion cutting fluids and emulsified oils, and it is easier to maintain and the workpieces after processing are also easy to clean.
Chorus semi-synthetic cutting fluids are refined with unique lubricants and composite additives, and are mainly used for cooling and lubrication during metal processing. It combines the advantages of synthetic cutting fluid and emulsified cutting fluid, has good lubrication and cooling effects, and has a long service life. It is an efficient, environmentally friendly and economical metalworking fluid, suitable for various metal processing occasions, can effectively improve processing efficiency, reduce costs, and extend the service life of equipment. It is an ideal choice for the metal processing industry.
Chorus water-soluble cutting fluid has excellent lubricity and anti-friction properties, which is very suitable for heavy-duty processing of aluminum alloys, automobile wheels and ferrous metals, significantly reduces tool wear, and greatly improves metal processing quality! Especially in the processing of ferrous metals, it performs well. Good antibacterial ability, maintains the long-term stability of the working emulsion, reduces odor, and keeps the workshop clean.
