The coolant tank with a safety lockout device is designed to ensure both reliable fluid supply and maximum operator safety during machine operation and maintenance. The tank is made of high-strength, corrosion-resistant materials, providing stable storage and circulation of coolant for CNC lathes. Its robust structure ensures long service life and minimal maintenance requirements. A key feature of this tank is the safety lockout device (LOTO), which prevents unauthorized access during operation. By locking the lid securely, it eliminates the risk of accidental opening, fluid leakage, or operator injury. This safety system is particularly important during maintenance and cleaning, ensuring that no fluid pressure or machine movement can occur while the system is locked. The tank is equipped with quick-release clamps for easy operation and a tight seal to prevent contamination or coolant loss. Combined with precise fluid piping and filtration systems, it ensures efficient cooling and stable machining quality. This design improves safety, reliability, and productivity, making it an ideal solution for modern automated production lines.
