What is Fully Synthetic Cutting Fluid?

1. What is Fully Synthetic Cutting Fluid?

Fully Synthetic Cutting Fluid is a mineral oil-free metalworking fluid made of synthetic lubricants, water-soluble additives, rust inhibitors, extreme pressure additives and other formulas. Unlike emulsified Cutting Fluids and semi-synthetic cutting fluids, Fully Synthetic Cutting Fluids are completely composed of water-soluble ingredients, have excellent cooling, lubrication, rust prevention and antibacterial properties, and are ideal for applications such as precision machining and high-speed cutting.

Fully synthetic cutting fluids are widely used in aerospace, medical equipment, automobile manufacturing, precision electronics and other industries because of their clean, environmentally friendly and non-corrupt characteristics. It not only improves machining quality, but also effectively reduces tool wear and extends equipment life, thereby reducing overall production costs.

2. Core advantages of Fully Synthetic Cutting Fluid

2.1 Superior cooling performance

The main component of fully synthetic cutting fluids is water, which has excellent thermal conductivity and can quickly take away the high temperature generated during the cutting process. This characteristic makes it particularly suitable for processes that require efficient heat dissipation, such as high-speed machining, deep hole drilling and precision grinding. It can effectively reduce thermal deformation of workpieces and improve machining accuracy.

2.2 Excellent lubricity

Although fully synthetic cutting fluid does not contain mineral oil, its special synthetic additives can provide excellent lubrication and reduce friction between the tool and the workpiece. This can not only reduce cutting force, but also reduce work hardening, improve surface finish, and extend tool life.

2.3 Cleanliness and environmental protection

Compared with traditional emulsified cutting fluids, fully synthetic cutting fluids do not produce oil mist or form oil deposits, thus keeping the working environment clean. In addition, it does not contain harmful mineral oil components, and waste liquid treatment is more environmentally friendly, which meets the requirements of modern industry for sustainable development.

2.4 Long-term antibacterial and stability

Traditional emulsified cutting fluids are prone to corruption and deterioration due to microbial contamination, resulting in odor and machining fluid failure. However, fully synthetic cutting fluids do not contain oily components, which can effectively inhibit the growth of bacteria and mold, have a longer service life, and reduce maintenance and replacement costs.

2.5 Excellent anti-rust performance

Fully synthetic cutting fluid contains water-soluble rust inhibitors, which can form a protective film on the metal surface during processing to prevent oxidation and corrosion. This makes it particularly suitable for rust prevention in the processing of ferrous metals (such as carbon steel and stainless steel) and non-ferrous metals (such as aluminum and copper).

3. Main application areas of Fully Synthetic Cutting Fluid

3.1 Precision machining industry

In high-precision machining fields such as aerospace, medical equipment, and semiconductor manufacturing, fully synthetic cutting fluids can meet strict dimensional tolerance requirements, reduce tool wear, and improve production efficiency with their excellent cooling performance and cleaning characteristics.

3.2 High-speed cutting and CNC machining

CNC turning, milling, drilling and other high-speed cutting processes require strong cooling to prevent tool overheating. Fully synthetic cutting fluids can not only keep the cutting area low, but also reduce chip adhesion and optimize cutting efficiency.

3.3 Hard material processing

Titanium alloys, stainless steel, nickel-based alloys and other materials have high hardness and poor thermal conductivity, so they have extremely high requirements for cooling and lubrication of cutting fluids. Fully synthetic cutting fluid can reduce cutting force and processing temperature and improve processing stability.

3.4 Grinding and Honing Processing

In precision grinding, honing and other processes, the high fluidity, low foaming characteristics and excellent cooling properties of fully synthetic cutting fluid make it an ideal choice, which can effectively reduce grinding burns and improve surface quality.

4. How to choose the right Fully Synthetic Cutting Fluid?

When choosing a fully synthetic cutting fluid, you need to consider the following key factors:

Applicable metal types: Different fully synthetic cutting fluids are optimized for different metals, such as aluminum alloys, stainless steel, copper alloys, etc. When choosing, you need to ensure that the liquid is non-corrosive to the material.

Processing method: Different processes such as milling, turning, drilling, and grinding have different requirements for the lubrication and cooling of cutting fluids, and the appropriate formula should be selected.

Rust resistance: For workpieces that require a long storage time, a cutting fluid with good rust resistance should be selected.

Environmental protection and safety: Environmentally friendly cutting fluids that do not contain harmful substances such as boron, nitrite, and chlorine should be selected to reduce the impact on the human body and the environment.

As an important processing fluid in the modern metal processing industry, Fully Synthetic Cutting Fluid is widely used in precision machining, high-speed cutting, and difficult-to-process material manufacturing due to its excellent cooling, lubrication, rust prevention, and environmental protection performance. When choosing a fully synthetic cutting fluid, companies should combine processing technology, material properties, and environmental protection requirements to ensure the best processing effect and economy, thereby improving production efficiency and reducing overall costs.
