Product Introduction

EP Full Synthetic Cutting Fluid is suitable for high-pressure, high-speed, and continuous metal machining conditions. Through stable extreme pressure lubrication and low-foaming control design, it improves tool life while reducing machining fluctuations and system maintenance risks.

Application Scenarios

High-Pressure CNC Machining Systems (≥8–30 bar)
Suitable for machining centers equipped with high-pressure internal cooling systems. Maintains a stable, low-foaming state under high-flow-rate fluid supply conditions, reducing cavitation and flow interruption risks, and improving machining continuity.

Automated Continuous Production Lines (24/7 Operation)
Suitable for batch processing environments of automotive parts and industrial components. Maintains stable lubrication performance under long-term cyclic use conditions, reducing fluid change frequency and downtime for maintenance.

Machining of High-Demand Metal Materials (Aluminum/Stainless Steel/Alloy Steel)
Suitable for machining 6061 and 7075 aluminum alloys and 304/316 stainless steel. Demonstrates stable performance in controlling tool sticking and material discoloration risks.

Precision Parts Machining
Suitable for machining molds, aerospace, and high-precision mechanical parts. Improves machining consistency and reduces tool wear fluctuations.

Core Advantages

EP Extreme Pressure Lubrication Protection: Forms a protective film in high-load cutting areas, reducing direct metal-to-metal contact and tool wear, suitable for heavy-duty and intermittent cutting conditions.

Thermal Stability and Dimensional Control: Quickly removes cutting heat, reducing workpiece thermal deformation and improving dimensional consistency.

High Pressure, Low Foaming Stability: Maintains low-foaming operation in high-pressure fluid supply systems, reducing cavitation and supply fluctuation risks, suitable for modern CNC machine tools.

Long-Term Use Stability: Delays cutting fluid aging and microbial growth, extending the service life of the fluid bath and reducing the frequency of fluid changes and maintenance.

Machining Cleanliness: Low residue and good water solubility reduce the cleaning burden on machine tools and workpieces, improving post-processing efficiency.

Technical Mechanism

Fully Synthetic Base System: Utilizes a mineral oil-free fully synthetic system, reducing the impact of raw material batch fluctuations on performance and ensuring higher consistency across different batches of cutting fluid.

EP Extreme Pressure Reaction Mechanism: Forms a chemically adsorbed film in high-temperature contact areas, enhancing boundary lubrication and reducing metal wear and micro-welding under high load conditions.

Metal Corrosion Inhibition System: Reduces the oxidation risk of aluminum and steel in water-based environments through corrosion inhibitor components, minimizing discoloration and pitting during processing.

Fluid Stabilization and Low-Fogging Control: Improves flow stability and cavitation resistance in high-pressure fluid supply systems by optimizing the surfactant system and bubble release mechanism.
