There are three main types of guide rails in CNC machining centers. According to the characteristics of surface contradictions, they can be divided into static pressure guide rails, sliding guide rails and rolling guide rails. These three guide rails are quite different. Everyone must have a certain understanding of this matter when carrying out CNC machining. . The two guide rail working surfaces of the liquid static pressure guide used for CNC processing open the oil chamber and enter the grease with a certain working pressure, which can produce static pressure oil floating, so that the working surface of the guide rail is in a pure liquid contradiction without causing Damage, the precision is maintained well; at the same time, the contradiction index is also very low, which greatly reduces the output power of the transmission device; there is no crawling at low speed, large load-bearing capacity, good bending stiffness; in addition, the oil also has practical vibration absorption and strong anti-vibration ability . The static pressure guide rail can be divided into liquid static pressure guide rails and gas static pressure guide rails. The defect of the static pressure guide rail is structurally chaotic, requiring an oil supply system, and the oil supply cleanliness requirements are high. CNC lathes are increasingly using static pressure guides. CNC punching machine high-speed punching machine flow Read More

The feed paths for CNC machining and finishing are basically carried out in the order of the parts. Therefore, the focus of clarifying the feed path is to clarify the feed paths for the initial processing and empty stroke arrangements. Products manufactured by CNC processing not only have smooth quality (expression: firm and stable, unchanged), but also have extremely high accuracy in processing products. The feeding path of the CNC machining center refers to the relative path of the turning tool starting from the point of the CNC tool (or the fixed starting point of the CNC lathe) until it returns to the point and completes the CNC machining procedure flow, including during the drilling process. and the relative paths during non-drilling, such as selection and cutting of CNC blades. The adoption of CNC processing greatly optimizes the processing process, maximizes profits and reduces production equipment, and saves costs for enterprises. CNC machining is very targeted. If you are changing the specifications of parts, you just need to write a program to modify it. CNC processing is also applicable Read More

Generally, it is not very common for CNC processing technology in daily life, but it is unquestionable that CNC processing technology has been widely used. Have you mastered it in detail in view of some of the structures and characteristics of CNC processing technology? The key to the common column-fixed horizontal CNC machining management center is these three types: column-fixed, spindle bearing box performs Y-direction fitness exercise, operating table performs Z-direction fitness exercise, and spindle bearing box performs Y-direction fitness exercise, and spindle bearing box performs Y-direction fitness exercise The operating table is also a X-directional fitness exercise. The operating table has the characteristics of good structural stiffness, high machining accuracy, and easy installation and adjustment. There are many horizontal machining centers for moving columns, and there are three types, all of which are dynamic. Column machining center. The operating platform is fixed, the column does X-direction fitness exercise, the main bearing box is hung sideways, and the Y-direction fitness exercise; the operating platform is fixed, the column does X-direction fitness exercise, and the main bearing box is hung sideways Read More

During the entire process of CNC machining, different main parameters of CNC blades will form different drilling shapes, thus forming different tool shapes. It causes direct harm to the reliability and process performance of the entire drilling process. Ideally, arc-edged diamond blades are used for milling. When processing soft metal materials, the processing surface of the product workpiece will produce ring peaks and ring valleys. The spacing between them is called the basic theoretical surface roughness. Its size is equivalent to f2/8 R (f is the cutting speed, R is the arc semi-warm of the CNC insert). So what aspects should be paid attention to when machining tools in CNC? Let us master the following sentences together: 1. The tool must be clamped firmly, and do not be too short in the collet; 2. Before each cable knives, check whether the CNC processing blade complies with the regulations, and the cable knives length should be marked according to the process table. The production and processing depth value is determined. Generally, a cable cutter with a slightly better 3 mm should be considered. Read More

The CNC machining center optimizes the selection of CNC machining tools based on the technical status of human-computer interaction technology. The rational use of tools and collets should be determined based on the professional processing capabilities of the machining center, the characteristics of workpiece raw materials, the production and processing process, cutting performance and other related factors. The selection of CNC machining tools is generally: easy to install and adjust, good bending stiffness, wear resistance and high accuracy. Starting from the production and processing needs, choose a shorter collet as much as possible to improve the bending stiffness of tool production and processing. When selecting cutting tools, the specifications and models of the tool should be consistent with the specifications and models of the surface of the product workpiece produced. Alloy milling cutters are often used for the production and processing of the peripheral bands of workpieces in the plan design drawings; when drilling the plan design, carbide tool blade turning tool should be selected; when processing mold seats and grooves of the workpiece, tool steel alloy milling cutters should be selected. ; Production and processing of workpiece surface surface or primary processing holes, you can choose to insert Read More

When machining precision parts, the operator must maintain the correct posture and have sufficient mental essence to arrange the work. If you find physical discomfort, you must ensure personal safety. You must immediately remove your job and go to the production workshop supervisor or higher level people reflect. The practical concepts are gathered, chatting is prohibited, and cooperation is carried out. Operators must not practice in situations of irritability and fatigue, so as to ensure personal safety, avoid accidents, and ensure operational safety. Before entering the job, ask whether their dress meets the job requirements. What other precautions are there in precision parts processing? Let’s learn about it together below. 1. Before processing precision parts, check whether grease is added to the moving parts of the equipment, then start and check the clutch, whether the brake system is normal, and rotate the CNC lathe idle parts for 1-3 minutes. If there are common faults in mechanical equipment, it is prohibited to be actually done. Operation; 2. Maintain the correct posture when machining precision parts. Read More

The influence of CNC machining position error on CNC machining accuracy Positioning error refers to the change or deviation of the mutual position between the actual surface, axis or symmetry surface of the workpiece to be processed and its ideal position, such as perpendicularity, displacement, symmetry, etc. In CNC machining, position error usually refers to dead area error. The processing errors caused by transmission clearance and elastic deformation during the processing of CNC parts, as well as the friction that the foreman needs to overcome during processing, are the main reasons for position errors. The open-loop system has a great impact on position accuracy, while the position accuracy of the closed-loop follow-up system mainly depends on displacement detection. Which CNC machining center is better? Processing accuracy error caused by CNC machining geometric error. When processing CNC machine tools, due to external factors such as external forces and heat generated during processing, the geometric accuracy of the machine tools is affected, and the parts generated during processing are geometrically deformed, resulting in geometric errors. From a theoretical analysis, CN Read More

CNC processing uses computer digitization and information digitization technology to control the motion and processing process of the machine tool. The device is a high-speed, reliable, multi-functional, intelligent and open intelligent universal pneumatic CNC system. CNC processing is also an important indicator to measure a country's technological development level, comprehensive national strength, as well as the degree of modernization of information technology. Its role is immeasurable in high-tech industries such as aviation, biology, and medicine, and is a concentrated reflection of national strength. Therefore, improving the technical level is an important way to improve the comprehensive national strength and national status. Therefore, what errors will occur in CNC processing? Let’s learn about it together: The principle error of CNC machining is mainly due to the use of an approximate machining motion mode or tool profile. Why is it called processing principle error? It is because there are errors in principle. This method is still feasible if the principle error does not exceed the allowable range. During use, manufacture Read More

At present, CNC lathe processing is no longer a mysterious process. Many companies use it for production, but not everyone has the right technology. When processing CNC lathes, in order to obtain ideal conditions for use, coolant should be used or a tool with good rigidity should be used. So how should we choose the parts for CNC lathe processing? Let’s learn about it together: 1. Reasonable selection of tools: 1. During rough-carrying processing, tools with high strength and durability should be selected to meet the requirements of back-cutting and feeding during rough-carrying processing; 2. When fine-cutting processing, high-precision and durable tools should be used to meet the processing accuracy requirements; 3. In order to reduce the time of tool change and facilitate tool alignment, machine knots and machine knots should be used as much as possible. 2. Reasonable selection of fixtures: 1. Try to use general fixtures to clamp the workpieces and avoid using special fixtures; 2. After the part positioning reference overlaps, the positioning error will be reduced. 3. Determine the processing method: 1. It should be able to be full Read More
