What are the Classifications of Precision Machining?

Precision machining is generally different in terms of type and specifications, and now precision machining has also increased a lot in these areas.  No matter how it is said, the technology of precision machining is also improved a lot now, precision mechanical parts processing is a type of mechanical processing, but it requires higher errors in processing and more stringent requirements on processing technology.  With the development of modern industry and the continuous changes in demand, precision mechanical processing is already more In terms of development, the direction of its development is becoming wider and wider, and the direction is becoming more and more detailed.  The direction of development is more and more showing its specialization.

With the development of technology, its technology is constantly improving The quality and precision of the processing are getting higher and higher.  The development of science and technology and economy also tightly grasped the development direction of precision machining.  So what are the classifications of precision machining now?

1, Positioning errors: Positioning errors mainly include reference misalignment errors and positioning pair manufacturing inaccurate errors.

2, Measurement error: When the part is measured during or after processing, the measurement accuracy is directly affected by the measurement method, the accuracy of the measuring tool, and the workpiece and subjective and objective factors.

3, Tool error: Any tool will inevitably produce wear during the cutting process, and thus cause the workpiece size and shape to change. Fixture error: The role of the fixture is to make the workpiece equivalent to the tool and the machine tool have the correct position, so the geometric error of the fixture has a great influence on the machining error.

4, Machine tool error: including spindle rotation error, guide rail error and transmission chain error. Spindle rotation error refers to the variation of the actual rotation axis of the spindle at each instant relative to its average rotation axis, which will directly affect the accuracy of the workpiece being processed.

1, Single-piece production: commodities with different structures and different sizes are produced individually, and are rarely repeated.

2, Mass production: the same products are produced in batches throughout the year, and the production process has certain repeatability.

3, High-volume production: the production quantity of goods is very large, and most of the work addresses are often repeated processing of a certain process of a certain part.
