Precision parts processing is a commonly used part of the CNC processing manufacturer, such as threaded parts, keys, pins, rolling bearings, etc., which have been completely standardized in all aspects such as marks, drawing methods, dimensions, structures, etc. and produced by professional CNC processing factories. Analysis on precision parts processing: The above parts are simply called CNC precision processing, which includes standardized fasteners, connecting parts, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. The narrow sense only includes standard fasteners. The standard parts commonly known as standard fasteners in China are the abbreviation of standard fasteners. They are a narrow concept, but the existence of a broad concept cannot be ruled out. In addition, there are industry standard parts, such as automotive standard parts, mold standard parts, etc., which are also considered precision parts processing. Precision parts processing is mainly due to the fact that the state has not set strict standards and specifications, and other accessories that are freely controlled by the enterprise in addition to relevant parameter regulations. There are many varieties of precision parts processing, but there are currently no very standard types. Read More

Aluminum alloy processing has gradually grown in the CNC processing industry in recent years, and many CNC processing plants are also continuing to achieve better turning centers and good tools, in order to better gain competitive advantages in the fierce industry. So how can we better gain a competitive advantage in a fierce industry? It is to make it the most exquisite in the tool industry, machine tool industry, and fixture industry through some difficult processing materials. Just like aluminum alloys are one of the characteristics that are process hardening. During the processing process, the shear angle is large, the chips are produced, and a relatively small contact area will be formed on the tool. In addition, the high cutting force during processing, combined with the friction force during chip flow, these factors will cause the local cutting heat of the tool to be too high. Titanium alloy has poor thermal conductivity, which causes the heat generated to be unable to be well transmitted. Therefore, a large amount of cutting heat is concentrated on the cutting edge and the tool surface. High cutting force, cutting heat will cause the occurrence of crescent tummy, and at the same time it will cause Read More

The processing sequence is considered according to the structure of the part, the blank state and the need for positioning and clamping, and emphasizes that the rigidity of the workpiece is not damaged. The order of the program should usually follow the following principles: 1: The basic priority principle At the beginning of the processing, the fine base surface is first processed, because the more precise the reference surface, the smaller the clamping error, so any CNC precision parts must be processed first. Rough processing and semi-finishing processing, and fine processing should also be done if necessary. For example, box parts generally first process the positioning plane and two positioning holes, and then use the plane and positioning holes as the precision reference processing hole system and other planes. If there are more than one fine base surface, it will be based on the order of base surface conversion and step by step The principle of improving processing accuracy is to arrange the processing of the base surface and main surfaces. 2: The processing order of each side is rough and then fine. The finishing process is carried out in order of rough processing and finishing processing to gradually improve the accuracy of the processing surface and reduce the surface roughness. 3: Principle of the main and later on the second principle of the part surface and assembly surface Read More

Here, Dongguan Ruibang Technology has made a summary of the CNC processing process with more than ten years of CNC processing experience. It can be said that it is an experienced driver in the classification of CNC processing processes. In hardware stamping factories, you usually see that the division of CNC CNC machining processes can generally be carried out according to the following methods: 1. The tool centralized sorting method is to divide the process according to the tool used, and use the same tool CNC to process all the parts. 2. Other parts that can be completed with the second knife and the third knife. This can reduce the number of tool change times, compress the time of the empty stroke, and reduce unnecessary positioning errors; 3. For parts with a lot of CNC processing content by processing part by processing part, the processing part can be divided into several parts according to its structural characteristics, such as the internal shape, shape, curved surface or plane, etc.; 4. Generally, the plane and positioning surface are first processed, and then the holes are processed; simple geometric shapes are first processed, and then complex geometric shapes are processed; first process parts with lower accuracy, then Read More

Today we are mainly talking about some matters in the processing technology and operation of precision parts. Since the number of batch processing of precision parts processing is relatively large, the production methods and cycles of precision parts processing are different from the operating specifications and processes of ordinary product processing. . Regarding the process of precision parts processing 1. The processing process path has great uncertainty. A part or product can have multiple processes, and there are many types of machinery, equipment and tooling fixtures required for the production process; 2. Hardware manufacturing enterprises Because it is mainly fragmented processing, the quality and yield of the product depend heavily on the technical level of workers, and the degree of automation is mainly at the unit level, such as CNC machine tools, flexible manufacturing systems, etc.; 3. Product parts are generally made of self-made and outsourced products. A combination of processing. For example, special processes such as electroplating, sandblasting, oxidation, silk screening and laser engraving will be entrusted to external manufacturers to process; 4. There are many parts required, and the workshop often requires a large number of material collection forms and Read More

When it comes to CNC processing, there must be reasonable processing methods and processing process steps, because these processes directly affect the processing quality, production efficiency and processing cost of CNC machining parts. Therefore, we must reasonably do the following six major steps for CNC processing: Step 1: First, coarse and then fine, for example, in the order of rough-semi-fine truck-fine truck, and gradually improve the processing accuracy. The rough cart will cut off most of the machining allowance on the workpiece surface (as shown in the refreshing point drawing line shown in Figure 2-4) in a short time. On the one hand, this improves the metal cutting rate, and on the other hand, it meets the margin uniformity requirements of precision trucks. If the uniformity of the allowance left after the rough car cannot meet the requirements of finishing processing, a semi-finishing car must be arranged to prepare for the finishing car. Precision car must ensure processing accuracy and cut out the part profile in one size according to the drawing size; Step 2: First near and then far. Under normal circumstances, first process the modern part of the tool point and away from the tool point. Read More

With the continuous development of industry, we have learned that various industries are developing rapidly, so in the process of precision parts processing, some damage may be caused. This may be mostly caused by our use, or it may be due to processing. This is caused during the process, so how to prevent damage during precision parts processing? Let’s take a look below! 1. Good casting structure design The casting wall thickness is as uniform as possible to avoid thermal joints and reduce thermal fatigue caused by local heat concentration of the mold. During the casting process, appropriate casting rounded corners should be provided at the corners of the casting to avoid stress caused by sharp corners of the mold. 2. Rationally design the mold structure 1. Precision parts and various components should have sufficient stiffness and strength to withstand pressure without deformation. The wall thickness of the mold must be sufficient to reduce deformation; 2. It is the design of the casting system to minimize erosion to the core; 3. The durability of each component is correctly selected and Read More

In fact, any product must undergo various series of processing and inspection before it can be arranged for external sales and use. According to data, mechanical parts processing is one of the workpieces with the most processing processes in the finished product. Ultimately, mechanical equipment with excellent performance can produce higher quality products. In today's modern industry development, the structure and configuration of machinery have become the focus of people's attention. Only by continuously improving technology can the future development of various industries play a greater role. Mechanical parts processing is a process of changing the size or performance of a workpiece through a mechanical device. Depending on the processing method, processing can be divided into cutting and pressurization. Machine parts are composed of several planes. When studying the relative relationship of planes, one must determine a benchmark. The benchmark is the points, lines, and surfaces that are used to determine the positions of other points, lines, and surfaces in the part. Depending on its different functions, the benchmark can be divided into design benchmarks and process benchmarks. Read More
