Mechanical parts processing should have the following seven aspects of the requirements:

(1) the requirements of tolerance accuracy:

The level of tolerance accuracy directly affects the machining process as well as the choice of machining equipment and the choice of machining parameters. This requires our process engineers and operators to have a quantitative and accurate grasp of the tolerance accuracy. In order to process the mechanical parts that meet the requirements.

(2) the requirements of the accuracy of the equipment:

The accuracy of the selected processing equipment itself, should be consistent with the precision requirements of mechanical parts processing, processing equipment precision if not up to, there will be no way to process mechanical parts to meet the requirements.

(3) the requirements of the environment:

Processing environment refers to the environment where the machine and equipment workshop, to meet the requirements of mechanical parts processing. Sometimes, the floor vibration and noise or air cleanliness, too much dust. Temperature, humidity will affect the precision and stability of mechanical parts processing.

(4) Requirements for materials:

Material processing of mechanical parts put forward differences in the requirements of the obvious, different material processing performance is different. Requirements for processing parameters are also different. We need to choose the appropriate tool according to the processing performance of the material, the number of revolutions, feed, and a variety of processing parameters.
