Cooling and lubrication system for chains, accessory equipment, cable routes, and machinery used in thermal vacuum extrusion. Suitable for oil spray devices on machine tools such as lathes, milling machines, drilling machines, and electric impulse tools. Design and materials highlights: - Attractive appearance with a bright color - Flexible length with free expansion and contraction - Adjustable and fixed by angle brackets - Non-conductive Key functions: - Lubricates transmissions - Cools machining centers - Machine cooling for cleaning and maintenance - Supports lubrication and transport tasks 2-3 practical use scenarios: - In a CNC turning/milling center with long operation cycles, it cools critical components and lubricates transmissions to reduce wear. - On workshop oil spray devices for lathes, mills, and drills to keep bearings and gears clean and cool during operation. - In automated production lines requiring flexible hose routing to deliver coolant to work points while maintaining electrical safety through non-conductive construction.
