Automatic alignment is an important balance correction area, referring to the mechanical products for rotation or reciprocating motion of the slender shaft, rod parts, heat treatment in the course of processing or deformation generated by high-precision measurements quickly to be corrected, so that the work piece to restore the state of a linear automatic operation. Automatic alignment process in the automobile industry, car industry in particular, are most frequently used, such as the engine crankshaft, camshaft, transmission of the drive shaft and the steering shaft in the steering rod, even in the shock absorber rods and other rod-type parts require rigorous alignment. In contrast, machine tools and other industrial products, some of the shaft parts, although there are very strict linearity requirements, the need to set the alignment in the manufacturing process, but rarely with automatic correction mode. The reason is the car for the mass production methods, in addition to ensuring the quality, but also must have high efficiency and low cost.  Despite the shape, size vary, but the alignment of all these artifacts, nature is similar, even in the same size but different machine on automatic alignment correction. Shaft, Rod parts of the automatic alignment process includes automatic determination of work piece alignment, automatic alignment operation and after the implementation of the test. Although there are many varieties of such equipment, structure, properties vary, but the basic form is a lot in common, the most important point is that these three functions are generally implemented on a station, unlike some other automatic calibration equipment, such as balancing, automatic weighing machine to the overall re-arrangement of so many forms. According to the level of automation, they are divided into two types of automatic and semi-automatic. The main difference is that the work piece, the cutting mode. In the latter case, be corrected shaft station entry and exit manually by the operator, the work piece in place, the operator presses the button, the following measurement, calibration and inspection will be done by machine automatically. Automatic straightening machine, the next most use lifts the pace of feeding conveyor means. This is a multi-station simultaneous effect of beam delivery device, not only has a high transmission speed, and reliable action.  Different specifications according to the work piece, even if the same professional manufacturer of products into multiple species, a number of series, not only on the working pressure (to adapt to different sizes of shaft parts), but also in the host-driven forms and ways of working have the difference. To host the form of, for example, there are mainly two: C-type similar to the hardness machine style door type is similar to the press. The former model in the form of various sizes on both automatic straightening machine applications, the latter is mainly used in large straightening machine.
