In the automotive industry plays a connection to the power plant and exercise equipment parts, in heavy machinery industry, plays a transmission power, lifting heavy objects, such as an important component of unloading. Slender shafts are driven shaft parts features throughout the axles in also play an important role. On the basis of their characteristics, on the part of its process for detailed analysis, to determine which process the selected type, model number and its considerations, and summarize the axles of the machining process.
