Five major processes of precision metal parts processing
Precision mechanical parts processing
Generally, the parts of precision machinery and equipment are processed and produced, which requires very high precision. Therefore, in addition to understanding the specific requirements of precision machinery parts processing for materials and the common skills of precision machinery parts processing, we should also To understand the steps in the processing of precision mechanical parts, let me share with you the 5 stages of precision mechanical parts processing.
1. Rough machining
The main consideration is to increase productivity. Most of the machining allowance of each machining surface is removed, and the fine reference is machined.
It is mainly to remove the defects that may occur after rough machining, and to complete the processing of the secondary surface at the same time. A certain machining accuracy must be achieved in order to prepare for the finishing stage and to ensure an appropriate finishing allowance.
In the finishing stage, large cutting speed, small feed and depth of cut are mainly used to remove the machining allowance left by semi-finishing, so that the surface of precision mechanical parts meets the technical requirements of the drawing.
It is mainly used to reduce the surface roughness or strengthen the machined surface, and is mainly used for surface processing with high surface roughness requirements.
5. Ultra-precision machining
Mainly use processing methods such as precision cutting, precision mirror grinding, precision grinding and polishing to make the machining accuracy of the workpiece 0.1-0.01μm, and the surface roughness value ra≤0.001μm.
The five stages of precision mechanical parts processing are from coarse to fine, and gradually refined. After these five stages of processing, the precision of mechanical parts can meet the requirements of customers. Yuntuo Machining focuses on the processing and manufacturing of precision mechanical parts. It can process according to customer requirements and produce precision mechanical parts that customers are satisfied with.
Methods of machining precision hardware and mechanical parts
With the continuous development of automation equipment, the development in the market is in full swing, which is a good benefit for businessmen. It can develop to today, which depends on the hard work of technicians. The processing of precision hardware and mechanical parts is one of them. So how to process precision hardware and mechanical parts? Let me answer it for you below.
The processing of fine mechanical parts is a kind of mechanical processing, but it has higher requirements for errors when stopping processing and stricter processing requirements. With the development of modern industry and changes in demand from time to time, fine machining used to be a development in many aspects. its specialization. With the development of science and technology, its technology is also constantly improving, the quality and accuracy of processing are also getting higher and higher, and the development of science and technology and economy has also tightly controlled the development direction of fine machining.
With the development of the machinery industry, the emergence of new design theories and methods, new materials, and new processes, mechanical parts have entered a new stage of development. , Computer Aided Design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology and other theories, have been gradually used in the study and design of mechanical parts.
Fine machining will only become more and more integrated, it is no longer just a simple form of machining. At the moment when it is seamlessly linked with high technology, it can better play its role, especially in the digitalization of the mechanical processing industry, which has made a qualitative leap in its development and can better serve the industrial development.
Processing features of precision mechanical parts:
1. Processing of fine mechanical parts
When the machining accuracy of fine parts is in nanometers, and finally in atomic units, the cutting and machining methods of ultra-fine parts can no longer be adapted. It is necessary to use special machining methods for fine parts, that is, the application of chemical energy, electrochemical energy, thermal energy or electrical energy. Make these energies beyond the binding energy between atoms, so as to remove the adhesion, bonding or lattice deformation between local atoms on the surface of the workpiece, so as to achieve the purpose of ultra-fine processing. This type of processing includes mechanochemical polishing, ion sputtering and ion implantation, electron beam exposure, laser beam processing, metal evaporation and molecular beam epitaxy.
2. Cutting of fine mechanical parts
There are mainly fine turning, mirror grinding and grinding, etc. Micro turning is performed on a fine lathe with a precision ground single crystal diamond turning tool, and the cutting thickness is only about 1 micron. It is often used for processing spherical, aspherical and flat mirrors of non-ferrous metal materials with high precision and highly bright surfaces.
Cold stamping can use a variety of processes including: – Embossing – the process of creating a three-dimensional pattern on the surface of a metal by applying pressure to the metal surface and then lifting the press while the metal is still in the shape of the die. The raised pattern is either polished or left as-is. – Raised Significantly – when the stamping is significantly higher than the metal’s surface, the excess metal is removed after stamping. – Rolled or engraved texture – a texture that is rolled onto the metal surface. – Rolled edge or Rolled edge and engraved – an edge is rolled and then engraved. – Electroformed coatings – a thin coating of metal is deposited on the part by electroplating. – Etching or oxidation – the metal is etched to change the color or to create a decorative pattern.
