Machined parts are widely used in the field of mechanical manufacturing, covering almost all types of mechanical equipment. The following are some common applications:
1. automobile manufacturing
Engine: engine block, cylinder head, crankshaft, camshaft, piston and other components are machined and manufactured. For example, the cylinder block needs to undergo a variety of machining processes such as milling, boring and drilling to ensure the dimensional accuracy and surface quality of each cylinder barrel and the performance and reliability of the engine.
Chassis: the transmission shaft, axle shaft, steering knuckle, wheel hub and other components in the chassis can not be processed without starting the machine. The transmission shaft needs to be machined with high-precision cylindrical surface and keyway by turning, grinding and other processes to realize the effective transmission of power.
Body: some complex parts in the body structure, such as door hinges, seat adjustment mechanism, also need machining to ensure their accuracy and reliability, so as to meet the requirements of automobile assembly and use.
2. Aerospace
Aircraft engine: blades, discs and casings of aircraft engines are key machining parts. The machining accuracy of blades is required to be high. Five axis linkage machining center and other equipment are required to ensure the aerodynamic performance and strength of blades.
Aircraft structural parts: fuselage frame, wing beam, landing gear and other structural parts are usually made of high-strength aluminum alloy or titanium alloy and other materials. Complex shapes and high-precision connection parts are processed through machining process to ensure the structural strength and lightweight requirements of the aircraft.
3. machine tool manufacturing
Bed: the bed is the basic part of the machine tool, which needs high rigidity and stability. After casting or welding the blank, it will go through multiple machining processes such as rough machining and finish machining to ensure the straightness, flatness and other accuracy requirements of the bed guide rail and provide correct guidance for the moving parts of the machine tool.
Spindle: the spindle is the key component of the machine tool to achieve cutting movement, and its accuracy and performance directly affect the processing quality. The main shaft is usually made of excellent alloy steel. After forging, machining, heat treatment and other processes, high-precision journal, taper hole and other parts are processed to ensure the rotation accuracy and bearing capacity of the main shaft.
Worktable: the worktable is used to install the workpiece, which needs to have good flatness and motion accuracy. Through the machining process, T-shaped groove, positioning hole and other structures are processed on the workbench to facilitate the clamping and positioning of the workpiece and meet the needs of different processing tasks.
4. mold manufacturing
Injection mold: the cavity, core, slider, thimble and other parts of the injection mold need to be manufactured by machining. Cavity and core are the key components to form the shape and internal structure of plastic products. NC machining center is usually used for milling, EDM and other processes to ensure its dimensional accuracy and surface quality, so as to produce high-quality plastic products.
Stamping die: punch, female die, discharge plate and other parts of stamping die also need to be machined. The cutting edges of punch and die need to have high hardness and wear resistance. Through the combination of machining and heat treatment, sharp cutting edges and correct dimensions can be processed to realize the stamping forming of plates.
5. construction machinery
Hydraulic system: key components of hydraulic components such as hydraulic pump, hydraulic motor and hydraulic cylinder, such as pump body, plunger and valve core, need high-precision machining. The machining accuracy of these components directly affects the working efficiency and stability of the hydraulic system. For example, the clearance between the plunger and the cylinder needs to be controlled in a very small range to ensure the sealing and pressure transmission of the hydraulic oil.
Working device: the structural parts of working devices such as loader bucket, excavator stick and boom are usually welded with high-strength steel plate, and then the connecting parts and mounting holes are processed through machining process to ensure the connection accuracy and movement flexibility between various parts.
