Precision mechanics (also known as "fine mechanics") is an engineering subject that talks about the design and building of smaller precision machines, often made up of measuring and controlling apparatus of different types.
First of all, Style RX is a pressure energized adaptation of the standard style or Gasket. The RX is designed to fit the same groove design as a standard style R, making the joints interchangeable.
PTFE has lower coefficient of friction and it is for this reason that PTFE washers are commonly used to assemble sections of moving parts in machines. This is because it reduces or eliminates lubrication costs and deterioration of various machine parts as a result of friction.
Teflon has certain unique characteristics which make it useful as gasketing material. It is immobile to all chemicals except molten alkali metals and fluorine at high temperatures and pressures. This i because Teflon has high heat resistance, low coefficient of friction and is non-adhesive.
First and foremost milling is the manufacturing process whereby machines use shear tools/cutters to rotate and remove material out of a station called a work-piece at a certain direction.
