What is precision mechanical?

Precision machining mainly includes fine turning, fine boring, fine milling, fine grinding and grinding.
① Fine turning and fine boring: Most of the precision light alloy (aluminum or magnesium alloy, etc.) parts of the aircraft are processed by this method.
②Fine milling: used to process aluminum or beryllium alloy structural parts with complex shapes.
③Fine grinding: used for machining shaft or hole parts.
④ Grinding: Use the principle of mutual research of mating parts to selectively process irregular raised parts on the processed surface.

The accuracy of the machine tool has two indicators: 1. The minimum movement of the machine coordinate axis, 2. The machine can accurately and stably output this minimum movement, which is the repeat positioning accuracy.

Precision mechanical is equipment for processing precision parts. They have precision grinders, precision lathes, precision lead screws, thread grinders, and precision surface grinders.

High-precision machine tools are iterative. Like general guide rails, flat plates use time for accuracy, or use each other as a benchmark. In other words, it is the averaging error. The accuracy of hydraulic bearings is an order of magnitude higher than that of ball bearings. And there are also a large number of zoom mechanisms available. For example, centimeters and micrometers. Because the accuracy limit that people can feel is only a few tenths of a millimeter, but the dial indicator dial indicator has increased the accuracy by hundreds of times through leverage. Low-precision machines are also used to make high-precision machines in the same way. The range is also smaller while increasing the resolution. After the arrival of informatization, it will be easier to improve accuracy. Because any ad converter can achieve at least 12-bit subdivision. The accuracy can also be increased to the degree of nm. For example, an electronic scale strain gauge can distinguish sub-micron displacements.
