When using wire EDM to machine impellers, there are the following advantages and applicable scenarios:

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.

6, xavier economic and environmental protection: in order to meet the performance requirements of the premise, the material selection also need to consider the economy and environmental protection. Selection of moderate cost, easy to obtain and less impact on the environment of the material helps to reduce production costs and reduce environmental pollution.

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.

In terms of the clamping method for turning machining, try to use the self-centering chuck for clamping and positioning. Because the self-centering chuck has a self-centering function, the clamping, positioning and alignment can be realized quickly after the parts are clamped, which can save Unnecessary auxiliary preparation time effectively improves processing efficiency.

The main cause of crankshaft fracture
(1) Long-term use of engine oil deteriorates; severe overloading and overhanging cause long-term overloading of the engine and cause tile burning accidents. The crankshaft was severely worn due to engine burnout.

The most common fatigue damage of the crankshaft, the main stressed part of the engine, is metal fatigue damage, that is, bending fatigue damage and torsional fatigue damage, and the occurrence probability of the former is greater than that of the latter. Bending fatigue cracks first develop in the connecting rod journal (crank pin) or main journal fillet, and then develop towards the crank arm. Torsional fatigue cracks occur in poorly processed oil holes or fillets, and then develop in the direction of the axis. Metal fatigue failure is the result of variable stress that changes periodically with time. Statistical analysis of crankshaft damage shows that about 80% is caused by bending fatigue.

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.

Heat Treatment
Heat treating involves subjecting a part to high temperatures to alter its properties. This can include hardening, tempering and annealing. Heat treating can improve the strength, durability and wear resistance of a part.

Laser Marking
Laser marking involves the use of a laser to create a permanent, high-contrast mark on the surface of a part. Laser marking can be used for both functional and decorative purposes and can be performed on a variety of materials.

In summary, there are a variety of surface treatments that can be applied to CNC machined parts to improve their durability, corrosion resistance and aesthetics. Anodizing, plating, powder coating, chemical conversion coating, heat treating and laser marking are all common surface treatments that can help extend the life of CNC machined parts. By choosing the right finish for your application, you can ensure that your CNC machined parts will be protected and function as intended for years to come.

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.
