What does the precision of internal and external circular grinding specifically refer to

Everything in the world is not absolute, we can only use relative terms. This principle is also applicable to internal and external circular grinding. Taking the accuracy of internal and external circular grinding as an example, the accuracy of all internal and external circular grinding is relatively high or low, because it is impossible for a workpiece processed by internal and external circular grinding to achieve absolute accuracy.

So what does the precision of internal and external circular grinding refer to?

The precision of internal and external circular grinding is actually a professional term used to evaluate the geometric parameters of the processed surface. The precision of internal and external circular grinding can be measured by tolerance levels, and the smaller the level value, the higher the precision of internal and external circular grinding.

The precision of internal and external circular grinding can be evaluated not only by precision, but also by the numerical value of machining error. The larger the error value of internal and external circular grinding, the greater the error. The relationship between the machining accuracy of internal and external circular grinding and the error is relative. If a workpiece has high machining accuracy, it indicates that its error is small.

Internal and external grinding processing
Although there is no absolute value for the accuracy of internal and external circular grinding, it is usually required that the machining error be within the tolerance range required by the part drawing.

So what is the relationship between the accuracy of internal and external circular grinding? The accuracy we mentioned above actually refers to whether the size and shape accuracy of the workpiece are similar to the parts on the drawing, and their accuracy is closely related to the positional accuracy. Usually, when designing machine parts and specifying the machining accuracy of parts, attention should be paid to controlling shape errors within positional tolerances, and positional errors should be less than dimensional tolerances.
