What Factors Affect The Precision Of Commodity Mould Processing?



The precision of commodity mould processing is very important. The higher the precision, the better the technology of commodity mould processing. What factors affect the precision of commodity mould processing?

Position accuracy

Commodity mould processing refers to the difference in actual positional accuracy between the surfaces of the parts after machining. The items for assessing positional accuracy include eight items: parallelism, verticality, inclination, concentricity, symmetry, position, round run out, and full run out. Position accuracy is controlled by positional tolerances, and the positional tolerances of each item are also divided into 12 accuracy levels.

Equipment quality issues:

The quality of the machine depends on the processing quality of the part and the assembly quality of the machine. The quality of the part processing precision commodity mould processing includes the machining accuracy and surface quality of the part. The machining precision refers to the actual geometric parameters (size, shape and position) after the part is machined. The degree to which the ideal geometric parameters are consistent. The difference between them is called the machining error.


The size of the commodity mould machining error reflects the level of machining accuracy. The greater the error, the lower the machining accuracy, the smaller the error, the higher the machining accuracy; the main aspects that affect the machining accuracy: dimensional accuracy, commodity mould processing, the actual size of the machined part and the tolerance of the part dimension.

I finally know why the commodity mould is so processing equipment, why?

Machining accuracy and machining error

Machining accuracy and machining error are the terms used to evaluate the geometric parameters of the machined surface. The accuracy of the commodity mould machining is measured by the tolerance level. The smaller the grade value is, the higher the precision is. The machining error is represented by a numerical value. The larger the value, the larger the error. High machining accuracy means that the machining error is small and vice versa.
