In recent years, with the continuous development of the automobile manufacturing industry, the automobile and parts manufacturing industries have become the largest and most important customers of the tool industry.

As the "heart" of the car, Bare Engine also play an important role in the processing of the whole vehicle, and their processing technology requirements are also higher than those of ordinary parts.

The connecting rod mechanism, also known as the low-pair mechanism, is one of the mechanical components. It refers to a mechanism formed by connecting several (more than two) parts that determine relative motion through a low pair (rotating pair or moving pair).

The connecting rod is an important part of Bare Engine. It connects the piston and the crankshaft, transmits the reciprocating motion of the piston, drives the rotational motion of the crankshaft, and outputs the power of the Mitsubishi Engine.

The connecting rod needs sufficient strength and rigidity to cope with the alternating pressure and inertia force of the expanding gas, so the processing accuracy of the connecting rod will directly affect the performance of diesel Bare Engine, so the precision processing selection of the inner hole of the connecting rod is also very important.
