Copper vertical milling with precision hole polishing hollow bushings.
The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.
Milling is a machining method in which a milling cutter is used as a tool to machine the surface of an object.
Milling refers to the use of rotating multi-edge tools to cut workpieces, and is a highly efficient processing method. When working, the tool rotates (for the main movement), the workpiece moves (for the feed movement), and the workpiece can also be fixed, but the rotating tool must also move (to complete the main movement and the feed movement at the same time).
①Each tooth of the milling cutter periodically participates in intermittent cutting.
②The cutting thickness of each tooth changes during the cutting process.
③The feed per tooth αf (mm/tooth) indicates the relative displacement of the workpiece within the time that the milling cutter rotates one tooth.
