Precision machining of precision machinery parts

Precision machining precision machinery parts which are the following:

1. precision geometry

Geometry Accuracy is the accuracy of the axis of each surface or other geometric shape of the component parts, such as the line is straight, whether flat surface, the normal section of each cylinder whether round like. Which allows the fluctuation range of "geometric tolerances" to mean, geometric tolerances smaller the number, the higher the precision of shape.

2. dimensional accuracy

Dimensional accuracy refers to the degree of precision machined parts dimensions, the "dimensional tolerance" to represent. Part of the same size, the higher the precision, the smaller the number tolerance.

3. The position accuracy

Location accuracy refers to the accuracy of the mutual position between the component parts of each surface, such as the two plane is parallel, if vertical, whether the two axes coaxial, so as to "position tolerance" to represent.
