How to transport high-precision grinding machine

How to transport high-precision grinding machine

1. Remove each component correctly It is difficult for high-precision grinding machine to be transported completely due to its own limitations. Therefore, it is necessary to properly disassemble all removable parts and effectively protect the edges and corners before transportation. If there is no gap at the bottom of the equipment and the fork teeth cannot enter, it is necessary to use a crane for loading and unloading, and the belt lifting can better protect the grinding machine, Only in this way can we ensure that all parts of the grinder are intact after being transported to the designated points. 2. If it is inconvenient to shift, use manual shift Because the high-precision grinding machine needs large lifting equipment for transportation, so the ground area occupied in the transportation process is large. The gates and channels set in many manufacturers' workshops are too narrow to allow the lifting equipment to pass through. In this case, the equipment is generally moved into the workshop by manual displacement, and manual operation can also ensure that the grinding machine is not damaged. 3. Protect the ground During the transportation of high-precision grinding machine, not only the equipment should be protected, but also the workshop floor should be protected. Because the weight of the grinding machine plus the weight of the lifting equipment can easily make the workshop floor scratch and wear, and the workshop floor generally requires anti-static leveling, so it is correct to protect the workshop floor before transporting the grinding machine in.

Which parts of high-precision grinding machine are the key to manufacture

Which parts of high-precision grinding machine are the key to manufacture

1. Various shafts, lead screws and guide rails The parameters of the shaft, lead screw and guide rail directly affect the basic performance of the high-precision grinding machine. It can be said that the parameter accuracy of these parts determines the processing accuracy of the grinding machine. Therefore, the parameters of these parts must be strictly in accordance with the manufacturing requirements without any deviation, otherwise it is easy to cause inaccurate processing accuracy of the grinding machine equipment. 2. Bearing The bearing of the grinder determines the working quality of the shaft parts, and the quality of the rolling element directly determines the working life and quality of the bearing. Therefore, the quality of the bearing in the manufacturing process of the high-precision grinder should also be paid special attention. 3. The cutting tool The importance of cutting tools and bearings is the same. Its quality is mainly determined by the manufacturing materials. Therefore, it is sufficient to select good raw materials for manufacturing. In addition, there are many choices for the shape of cutting tools. Customers can customize the shape of cutting tools according to their own needs when selecting.

How to properly maintain high-precision grinding machine

How to properly maintain high-precision grinding machine

1. Debugging grinding wheel balance before grinding The high-precision grinding machine must adjust the balance of the grinding wheel before starting each work to avoid the grinding wheel deviation before grinding, which may lead to the processing and grinding not in place or causing errors in the work, which not only interferes with the normal work of the grinding wheel but also is not conducive to the efficiency of the grinding process. Therefore, adjusting the balance of the grinding wheel is the maintenance work that must be done for each high-precision grinding machine, so as to give full play to the strength of the grinding machine. 2. Lubricating maintenance after the grinding machine is completed The whole equipment of high-precision grinding machine has many sliding parts. After each operation is completed, the lubricating oil should be wiped clean in time for maintenance. This can improve the lubrication and flexibility of each joint, and it is not easy to rust and stiffen, greatly improving the grinding efficiency of the grinding machine in daily work, which is a very important maintenance measure. 3. Clean up dust regularly The basic maintenance of daily work is commissioning and oiling, but the high-precision grinding machine also needs regular maintenance, because the grinding machine will accumulate a lot of dust after working for a period of time, not only the dust on the surface area, but also the dust in the dust suction pipe. Therefore, regular dust cleaning and maintenance is very important, which can check out the problems of the grinding machine and avoid affecting the normal operation of the grinding machine due to the infiltration of dust, Avoid working failure.

What are the factors that affect the surface roughness of high-precision grinding machine

What are the factors that affect the surface roughness of high-precision grinding machine

1. Grinding wheel One of the factors affecting the surface roughness of the high-precision grinding machine is the grinding wheel, which mainly includes the size and hardness of the grinding wheel and the dressing of the grinding wheel. The granularity of the grinding wheel is directly related to the number of abrasive grains per unit area of the grinding wheel. At the same time, the finer the grinding surface score, the more shiny and refined the surface. However, the fineness of the grain size should also be appropriate, not too fine, otherwise the grinding wheel will be blocked, and ripple and burn will also occur. 2. Workpiece material The material of the workpiece will also affect the surface roughness of the high-precision grinding machine, and the specific factors include the hardness, plasticity, thermal conductivity, etc. of the material. The influence of these factors on surface roughness is direct. For example, soft materials such as aluminum-copper alloy will cause clogging of the grinding wheel, which is difficult to grind, while heat-resistant alloys with large plasticity and poor thermal conductivity will cause the grinding surface to become more rough. 3. Processing conditions The surface roughness of the high-precision grinding machine is also related to the processing conditions, such as the cooling conditions of grinding amount and the accuracy and anti-vibration of the process system. The grinding parameters are directly related to both the grinding wheel speed and the workpiece speed, and are also affected by the grinding depth and the longitudinal feed rate. The increase of the grinding wheel speed may cause the grinding speed to exceed the propagation speed of the plastic deformation of the surface metal, and the material deformation time is short, thus reducing the roughness of the grinding surface.

What are the principles of non-standard hardware parts processing technology?

What are the principles of non-standard hardware parts processing technology?

What is the actual technical standard for processing non-standard hardware parts? According to the survey, most of the customers also do not know the actual processing technical standards of the machining manufacturers. Next, we need Guowei Precision Manufacturing to interpret them specifically: What is the technical standard for processing non-standard hardware parts? (1) . In order to ensure the processing precision, unsmooth and finish machining are separated * * Yes. When the drilling volume is large, due to rough machining. The machining precision standard for some parts is high. After rough machining and finish machining, the whole process of quenching and tempering shall be distributed or ultra-low temperature quenching to remove the thermal stress. The workpiece of the product has a significant processing hardening condition in cutting speed, clamping force, heat generation, and solving the shape. The workpiece of the product has a large thermal stress. If it is not smooth and continuous rough machining, the precision of the part will quickly lose after finishing because of the initial distribution of internal stress. (2) Select machinery and equipment effectively. High machining precision is required. Rough machining is mainly to cut off the processing capacity of most mechanical equipment. Rough machining should have higher energy and high precision of equipment, and the whole process of machining should be regulated by higher precision CNC lathe. The rough and finish machining equipment are different, which can give full play to the working capacity of the machine equipment and increase the service life of the precision CNC lathe. (3) Heat treatment methods are often assigned to the lines in the whole process of processing. In order to better improve the physical properties of parts, heat treatment and quenching are usually allocated to processing. The position distribution is as follows: heat treatment method is used to improve the drilling processing characteristics of metal materials, such as quenching, normalizing, quenching, and general layout before processing.

What are the characteristics of precision machined parts

What are the characteristics of precision machined parts

The higher the precision of precision parts in practical applications, the more refined they are, the more they can reflect the processing level and quality. At the same time, these products are also more popular with consumers. Generally speaking, NC machining has incomparable advantages and features in processing, and its product quality is usually higher. What are the characteristics of Guowei precision parts processing? 1. First of all, the production efficiency of CNC precision parts processing is higher. CNC parts processing can process multiple surfaces at the same time. Compared with ordinary lathe processing, it can save many processes and time, and the quality of parts processed by CNC is much more stable than that of ordinary lathe. 2. NC precision parts processing plays an irreplaceable role in the development of new products. Generally speaking, parts with different complexity can be processed through programming, while the modification and update design only need to change the program of the lathe, which can greatly shorten the product development cycle. 3. Guowei precision parts processing is highly automated, which greatly reduces the physical labor intensity of workers. Workers do not need to operate the whole process like ordinary lathes in the processing process, mainly to observe and supervise lathes. However, the corresponding numerical control processing technology is higher than the ordinary lathe, so it requires higher mental labor than the ordinary lathe. 4. The initial investment is larger than that of ordinary lathe, because the price of CNC lathe is very high, and its maintenance cost and the first preparation period for processing are long.

Introduction to process flow of hardware parts processing

Introduction to process flow of hardware parts processing

Summary of the technological process and precautions of CNC machining of hardware parts. It is well known that CNC machining is applicable to the production of hand models and small batch production, and various types of parts are processed in large batches. The precision of CNC machining parts is the highest in the mechanical manufacturing industry, and it can serve the precision parts processing with high precision requirements in various industries. So, what is the CNC process flow of hardware parts? Here, Guowei Precision, based on its years of technical experience in the industry, summarized the working process of CNC machining. For the process sequence of CNC machining, first of all, before CNC machining, you must clearly see the process flow content contained in the machining drawing, and clearly know the part, shape, dimensions of the drawing to be processed and the processing content of the next process. Write the drawing to be processed into the program, and then connect the computer to the CNC machine tool. Command the CNC machine tool to operate and process through the program, and process the rapid prototyping parts. After rough machining, self-inspection shall be carried out in time to adjust the data with errors in time. The parts shall be processed after rough machining confirmation. After finishing, the workers shall carry out self-inspection on the shape and size of the processing part. After the self-inspection of the workpiece is completed, the workpiece can be removed and sent to the inspector for special inspection after confirming that it conforms to the drawing and process requirements. When small batch processing is required, batch processing can only be carried out after * * hand board models are confirmed to be qualified. There are many points to be noted in the whole processing process, otherwise it is easy to cause parts scrapping. Fengrui model summarizes several most noteworthy items: 1. Whether the processing process of parts is correct and the starting point of counting; 2. Whether the mechanical parts are loose during processing; 3. The position and dimension between the machined surfaces. The basic length and width of the vertical plane shall be measured, and the base point size marked on the measurement drawing of the inclined plane shall be measured. After checking the position and size, measure the rough machined shape ruler (except for circular arc); 4. The azimuth dimension of the machined surface. Whether the dimension from the part processing surface to the reference edge (reference point) meets the drawing requirements; 5. Before clamping the workpiece, measure whether the blank size meets the drawing requirements. When clamping the workpiece, carefully check whether its placement is consistent with the programming instructions
