[1] Designed with assistance from instrument maker Zigmant Kanstul, it was originally intended to replace the traditional rotary valve on the French horn , but instead revolutionized the design of trombone valve ...
The properties that are sought after in a good cutting fluid are the ability to: Keep the workpiece at a stable temperature (critical when working to close tolerances). Very warm is acceptable, but extremely hot or alternating hot-and-cold are avoided. Maximize the life of the cutting tip by lubricating the working edge and reducing tip welding.
Graphite. Used in air compressors, food industry, railway track joints, brass instrument valves, piano actions, open gear, ball bearings, machine-shop works, etc. It is also very common for lubricating locks, since a liquid lubricant allows particles to get stuck in the lock worsening the problem. It is often used to lubricate the internal ...
The last form is a plastic bearing, which has the lubricant molded into the bearing. The lubricant is released as the bearing is run in.
