  • CNC Machining Technology of Sealed Pipe Taper Thread

    The CNC machining technology of sealing pipe taper threads is discussed, the current standards of Chinese pipe threads are explained, the characteristics, process analysis and program design of sealing pipe taper threads are explained in detail, and the processing is combined with specific examples. The technology has been systematically analyzed in order to provide reference for the needs of relevant parties.


  • How to machine inconel 718?

    Inconel 718 is a precipitation hardening nickel-chromium alloy containing a large amount of iron, niobium and molybdenum, and a relatively small amount of aluminum and titanium


  • The Machining Method Of Constant Velocity Plane Spiral Surface

    When the contour curve of the straight forming surface on the workpiece is more complicated, it has not only straight lines and arcs, but also curves with other shapes, such as constant velocity spirals, constant acceleration and constant deceleration spirals, certain regular function curves and irregular When it is composed of non-functional curves, it can be called a complex forming surface.


  • What Is Bakelite?

    Bakelite is the first plastic product to be put into industrial production. Its chemical name is phenolic. It has high mechanical strength, good insulation, heat resistance and corrosion resistance. Headphones, phone cases, instrument cases, etc., the name "bakelite".


  • The Functions And Characteristics Of Precision Parts Machining Indexable Milling Cutters

    There are many structures and varieties of indexable milling cutters, including various cemented carbide indexable face milling cutters, end mills, slot milling cutters, forming milling cutters and crankshaft milling cutters, etc.


  • The Technology Range And Machining Accuracy Of Combined Lathes

    The combination lathe is mainly used for two types of processes: plane machining and hole processing. Plane machining includes sharp plane, pigeon (profit) plane, car end face;


  • What is InconelX-750

    Inconel X-750 alloy is mainly a nickel-based superalloy that is age-strengthened with γ ′ [Ni3 (Al, Ti, Nb)] phase. It has good corrosion resistance and oxidation resistance below 980 ℃, and a high Strength, below 540 ℃ has good relaxation resistance, but also has good forming properties and welding performance.


  • What is the forgeability of metal materials?

    The factor that has a greater influence on the forgeability of the metal is the shaping of the metal itself. The better the plasticity, the less likely it is to crack during forging.


  • The Elements Of Affect The Turn-mill Machine Tools Machining Accuracy

    For high-speed precision turning and milling machine tools, the spindle system is an electric spindle structure, and the machining accuracy of the machine tool depends to a large extent on the accuracy of the machine tool electric spindle system and is affected by the accuracy of the tool.


  • Why use inconel 718 to manufacturing aircraft parts

    A long time ago, people began to use broaching methods to process tongue and groove on gas turbine disks. The blade is fixed on the turbine disk through a tongue and groove. However, broaching will cause changes in the structure of the surface and underlying layers of the turbine disk, which will affect the fatigue resistance of the wheel.


  • Analysis of Machining Large Titanium Turbine Blades Profile Process

    The fan blades of the large bypass ratio turbofan engine have basically reached more than 500MM in terms of length and size. This large-scale structural feature makes the centrifugal force and vibration stress to be very large during their work, so it has also become a large turbo fan engine Very important parts.


  • Analysis of Cnc Precision Carving Process

    CNC precision engraving machine is a kind of CNC machine tools. Metal engraving machine can perform non-contact cutting and punching on metal or non-metallic plates and pipes, especially suitable for laser cutting of stainless steel plates, iron plates, silicon wafers, ceramics, titanium alloys, epoxy, A3 steel, diamond and other materials .
