When using wire EDM to machine impellers, there are the following advantages and applicable scenarios:
Aluminum alloy precision parts and products are welcome because of light weight and exquisite and exquisite, the applications in industrial areas and daily necessities are increasingly wide. Especially in recent years, with the development of science and technology, the demand for product diversity is getting stronger. Therefore, the better the process of aluminum alloy products, the more favored by people, the greater the market demand, the higher the benefits. CNC machining is one of the best processing methods of current aluminum alloy shell products.
High-precision machining: Wire EDM is a non-contact machining method that cuts the material by electric spark discharge, so it can achieve very high machining accuracy. This is very important for applications that require high-precision impeller contours, such as aerospace, automotive, and energy industries.
The ball is fitted with a spiral interpolation method, which can be continuously processed by a taper hole; using a ball-head milling cutter and a spiral interpolation drill bit, boring and chamfer processing; vertical milling cutter cooperation, etc. Holes can be processed for half-precision and precision parts; the fingering cutter for processing threads is fitted with a spiral interpolation method, and various threaded holes can be performed.
In order to meet the diversity of aluminum outer shell products, high quality needs, the process techniques must be summarized during processing, and Changhong is precise according to the multi-year CNC processing experience, summarizing the processing skills that should be paid attention to in aluminum alloy shell processing.
Complex shape machining: Wire EDM can be used to machine impellers with complex shapes, including spiral blades and very small blades. Since wire EDM is based on pre-programmed paths, it can achieve almost any shape of impeller.
Hard material machining: Impellers are usually made of high-strength and wear-resistant materials, such as titanium alloys, nickel-based alloys, etc. Wire EDM can effectively machine these hard materials because it does not rely on traditional cutting tools, but cuts by electric spark discharge.
Deformation-free machining: Since wire EDM is non-contact machining, it does not apply large forces or heat-affected zones, so deformation of the material can be avoided. This is very important for applications that need to maintain the shape and dimensional stability of the impeller.
Mass production and automation: Wire EDM can be applied to situations where impellers are produced in large quantities. Once the program is written, it can be processed continuously in an automated manner to improve production efficiency.
In general, the advantages of wire cutting impellers are high precision and complex shape processing capabilities, suitable for hard materials and applications that require shape stability. It is an advanced processing method suitable for specific impeller requirements.
(3) Overlay welding is used in the repair of the crankshaft, which destroys the dynamic balance of the crankshaft, and the balance check is not done. The unbalance exceeds the standard, which causes a large vibration of the engine and leads to the fracture of the crankshaft.
If high-efficiency aluminum alloy precision parts are processed, tool interpolation can be utilized. In particular, when using high-speed milling, the loads of each knife tooth are relatively light, and thus use the same coating hard alloy milling cutter, a variety of high-speed high-precision well processing can be performed on a variety of processed materials.
1, high strength: aviation parts need to withstand great mechanical stress and pressure, so the material must have high strength characteristics to ensure that the parts can maintain stability and reliability in extreme working conditions.
(2) After the engine is repaired, the vehicle has not passed the running-in period, that is, it is overloaded and overslung, and the engine is overloaded for a long time, so that the crankshaft load exceeds the allowable limit.
How a crankshaft works
The crankshaft is one of the most typical and important parts in the engine. Its function is to convert the gas pressure transmitted by the piston connecting rod into torque, output work as power, drive other working mechanisms, and drive the auxiliary equipment of the internal combustion engine to work.
Choose reasonable cutting amount, the staff is selected as the cutting speed of the material, hardness, cutting state, the species of the material, the type of material, the cut-cutxia, and the like. These conditions are essential conditions that effectively reduce machine wear.
CNC machining techniques require that the control system can logically process programs with control encoding or other symbol instructions, coding it through the computer, thereby making machine tools and processing parts. The hair material is processed into semi-finished product parts and Xavier the like by tool cutting.
