Processing/casting methods for high product parts


Influence mechanical parts processing plant equipment accuracy of various causes, so parts processing caused by a variety of errors, based on the characteristics can be divided into three categories, namely, gross error, accidental error and systematic error.

In the whole process of high product parts processing, accidental error is the work of the equipment itself some did not manipulate the subtle elements, such as transmission gears in the gap shift, the elastic deformation of the parts, lubricating grease produced by the stagnation, sliding friction, such as the error caused by the change. The size of this error shift and error orientation has no regularity, these factors should be high product parts processing plant to control rigorously. Contemporary CNC lathes and CNC machining centers are able to influence the factors at any time and place supervision and feedback production and processing, fully automatic calibration. For the measurement results of the testing instrument, can be multiple times, such as precision and accurate measurement, the results will be processed to take the value.

In the high product parts processing the whole process, coarse error is the equipment work because of intense instantaneous speed change, such as impact, impact and work standard of the ups and downs of the error caused by this type of error machine equipment parts processing plant can be discarded for processing.

In the whole process of high product parts processing, systematic error is the key element that jeopardizes the accuracy of the equipment, accounting for the main component in all kinds of error. Generally by the core components of the equipment, parts accuracy and installation accuracy decision-making, the size of the error and the trend of change is fixed and will not change, can choose the error correction organization to reduce and clean up the system error on the equipment working accuracy of the hazards.
