Problems solved by technology

However, this processing method generally has problems such as single processing materials, and the three-dimensional body processing ability is poor, and it can only process two-dimensional or quasi-three-dimensional micro-mechanical parts with a relatively simple structure; another manufacturing method based on traditional precision machining Technology, this processing technology has a wide range of processing materials, and can process three-dimensional parts with complex structural shapes in batches
However, due to the influence of factors such as processing principles, machine tools, tools, and clamping, the processing accuracy of this method is low. At the same time, due to the extremely small feature size of the processed parts, the processing technology is very complicated and the reliability of processing is poor.
Therefore, it is difficult to apply widely

Embodiment Construction

[0016] Below in conjunction with the accompanying drawings, the present invention will be further described in detail by taking the machining material as 45# steel and machining the outer surface of a shaft part with a diameter of 10mm as an example, and requiring certain strength and wear resistance.

[0017] 1) Analyze the machining process on the outer surface of the shaft part. The blank is selected as a round bar with a diameter of 15mm. It is determined to use rough turning, semi-finishing turning, and grinding technology. The machining allowance is 3mm, 1.5mm, and 0.6mm, respectively. To make the tolerance level reach IT7, according to the economical processing accuracy, the manufacturing tolerance of parts can be enlarged by 3-5μm.

[0018] 2) According to the processing technology determined in the previous step, carry out rough turning, fine turning processing, and then grinding processing, so that the parts become irreparable waste products.

[0019] 3) Use the oute...

Abstract

The invention relates to an integrated manufacturing method of microminiature parts based on surface coating. The technology integrates multiple technologies such as precision machining / ultraprecision machining, surface coating, precision measurement and the like, adopts the parts precision machining mode of firstly '-'(removing machining) and then '+' (combination machining), and compensates thesizes of parts through accurately controlling the thickness of a coating (plating) layer on the basis of precision measurement, thus improving machining precision and surface quality considering thatthe thickness of the coating layer can be precisely controlled to be in the nanometer level. The precision / ultraprecision machining technologies have wide range of machining materials and simple method, and can realize mass production of microminiature parts with three-dimensional complex structures; and the method of the invention be widely applied to the machining of various microminiature parts such as steel, alloy and the like.

Description

technical field [0001] The invention relates to a method for manufacturing miniature parts, in particular to an integrated manufacturing method for micro parts based on surface coating. Background technique [0002] With the development of aerospace, national defense industry, precision instruments, medicine and bioengineering technology, as an important development direction of advanced Due to the advantages of small size, light weight, low energy consumption and low inertia, parts are becoming more and more widely used. [0003] Today, there are mainly two methods for the manufacture of micro-miniature parts. One is the relatively mature microelectronic technology represented by silicon microtechnology and LIGA technology, that is, MEMS technology, and the other method is mainly based on traditional precision machining as the background manufacturing technology, such as turning, milling, drilling, polishing Wait. Professor Yu Huadong of Changchun University of Science a...
