Water-miscible coolant is formulated using fourth-generation nano-emulsion technology. The product comprises 90% purified water and 10% concentrate. Concentrate concentration in circulating systems is adjusted between 3 to 8% by volume. Its viscosity at 20°C is approximately 25 to 35 centipoise. A stable pH of 9.2 to 9.8 provides strong anti-corrosion properties. Antibacterial, anti-foam, and anti-rust additives are integrated into its molecular structure. The products flash point is above 150°C. This coolant is designed for metal turning, milling, and grinding processes.
The chemical structure includes triethanolamine and synthetic fatty acids. This blend ensures emulsion stability for up to 6 months in closed systems. The protective coating forms a 50 to 100-nanometer film on the workpiece. This coating provides corrosion resistance for up to 300 hours in salt spray tests. Its cooling performance reduces cutting zone temperature by 40%. The oil is fully compatible with all ferrous and non-ferrous alloys. Consumption is approximately 2 liters per hour for medium-duty machining. The products residue is non-toxic and biodegradable. Its service life in tanks with proper maintenance reaches 12 months.You can order and buy abzar jahan boresh from Iran by contacting us through whatsaap and email.

The Difference Between Machine and Hand Reaming
Hand reaming relies on the operators force and adjustable tools like expansion reamers. This method suits low volume and relatively open tolerances like H9. Its accuracy heavily depends on the operators skill. Machine reaming is performed on equipment like drill presses or milling machines. This method uses fixed reamers with high manufacturing precision. Very tight tolerances like H7 are easily achievable with this process. The speed and repeatability of machine reaming are significantly higher. Furthermore, the internal surface finish quality is more uniform and superior with the machine method. The choice depends on production volume, required accuracy, and available resources.
