There are many sliding friction pairs in the hydraulic excavator. Because the sliding friction pairs of the excavator bear heavy loads and the working conditions are relatively bad, the relative sliding friction pairs are easy to fail. However, most of the failures are not fractures, but different forms of wear on the contact surface or surface. In view of the fact that the excavator pin shaft is prone to adhesive wear and fatigue wear, we use high-strength alloy structural steel 42C; M as the pin material after quenching and tempering, surface after high-frequency quenching, EDM surface strengthening, the surface is deep . The white tungsten-cobalt hard alloy reinforced layer of 1~.3 has a hardness of up to HRC74 or higher. by. The processing efficiency is very close to that of the NX154 blade special machine produced by Swiss STELARG. Use the on-line machining accuracy measurement function of this machine to measure the G106-level guide vanes and the blade shape file. A hard alloy having a higher hardness is used as the tool electrode 11, and the pin 12 is used as a negative electrode to alternately short-circuit and open the surface of the positive and negative electrodes to perform electric pulse discharge. The energy stored on the capacitor in the C line forms the spark or tool name and specification. The cutting amount is the number of the process name. The cutting speed is the roughing degree.

Subsequently, free-form surface parts such as the overall marine propeller are machined.

Plastic Injection Molding Factory.We are advanced China Plastic Injection Molding manufacturers. Our Plastic Injection Molding manufacturing methods are extremely accurate and fast. They can provide unlimited rapid prototype plastic injection molding capabilities for a wide variety of high-volume products. The method is also used for low volume, high-quality plastic parts for everything from toy cars to giant television screens. Rapid prototyping is the process of designing and creating a new product or component using plastic injection molds. It is a critical process because it helps identify new product characteristics by testing them over again before a product goes to production.Plastic injection molds allow designers and engineers to create detailed models from digital designs that can then be brought to life into a physical product. This kind of design sharing provides a tremendous advantage for companies trying to reduce product development costs.
Many rapid injection molding tools include tools that are designed to assist the manufacturer with their overall production efforts. These tools can offer you a number of additional services including computer software designed to help you streamline your production efforts and increase your profitability. By streamlining your efforts, you can expect to see a significant increase in your production rate and efficiency.
RongNa offer OEM/ODM custom rapid prototype plastic injection tooling which can help you reduce the time necessary to create new parts and can save you valuable money on material costs.
