With the formation of trends such as the expansion of production scale and global industrial transfer in military, aerospace, mold, transportation, construction machinery and other various equipment manufacturing industries, and the strong demand for multi-level machine tool products in related industries, the demand for metal cutting in my country is increasing. Increased, cutting power tool holders gradually enter the golden development period, and will usher in an explosive period in the next few years.



In the first half of this year, the overall development of my country's manufacturing industry picked up, with the continued advancement of intelligent upgrading, and the booming of robots and automation equipment. According to data from the National Bureau of Statistics, the cumulative output of domestic industrial robots from January to June reached 59,000 units, an increase of 52% year-on-year, and the year-on-year increase in June reached 61%, ranking first among all types of industrial products; metal cutting from January to June The cumulative output of machine tools reached 400,000 units, a year-on-year increase of 8.7%.


Cutting power tool holders are one of the important components of metal cutting machine tools. Affected by this wave of machine tool market demand from 2016 to the present, the production capacity of my country's metal cutting machine tool industry has been increasing. With the formation of production scale expansion and global industrial transfer of automobile and parts, aerospace, molds, railway transportation equipment, construction machinery and other various equipment manufacturing industries, as well as the strong demand for multi-level machine tool products in related industries, my country's metal cutting power tool holders are ushering in an accelerated period of development.



The boring and milling power tool holder has a simple structure and is easy to maintain. The boring and milling power tool holder is suitable for installation on planers, milling machines or various special machines. It can be used for heavy cutting, boring, etc., and two milling heads, left milling and right milling, can be used for vertical milling, horizontal milling, and horizontal milling. , Reverse horizontal milling, and a 90-degree milling head can be installed. It can be used in conjunction with planer, planer milling machine or vertical lathe. It has the functions of milling, boring, drilling, tapping, countersinking, etc., and can be widely used for various types of plates in industries such as automobiles, locomotives, machinery, machine tools, and tools. Processing of parts such as type, box type, rack type, etc.



This power toolholder is mainly milling, supplemented by boring, and can be used with right-angle milling heads according to user requirements, which can realize one-side clamping and five-side processing, which greatly improves processing quality and production efficiency. Commonly used for rough milling and semi-finish milling of large planes, with a depth of cut of 10mm. Milling power toolholders are generally used in conjunction with mechanical, hydraulic sliding and milling tables, and can be combined into combined milling machines or special milling machine tools. Milling plane or tank washing process of castings, steel and non-ferrous metal parts. It can also be used for gantry planer to gantry milling machine.



The quality of the milling head determines the performance of the modular machine tool. The driven tool holder is basically formed by assembled parts and assembled completely according to the size requirements processed by the customer. That is to say, the performance of the driven tool holder depends on the quality of the parts and the scientificity of the assembly process. An important reason for my country's long-term dependence on imports of high-precision machine tools is that the accuracy of domestically produced equipment is insufficient, and if there is still a gap in high-precision equipment, high-precision processing machine tools must be used. The quality of the mandrel of the milling head determines the quality of the power tool holder. The mandrel is constantly rotating and reciprocating, and it also has to work under force. Therefore, it is necessary to use good materials to make the production mandrel. Carry out hard processing, otherwise it is quite easy to wear, which will increase the jitter of the driven tool holder and damage the processed parts.



1. The mandrel of the driven tool holder is the most critical. It is constantly rotating and reciprocating, and it also needs to work under force. Therefore, good materials must be used and hardened and hardened. Otherwise, it is quite easy to wear and cause the processing effect to degrade. The jitter of the driven tool holder increases and cannot be processed;



2. The bearing part is directly sleeved on the periphery of the mandrel. When the mandrel moves back and forth, it also rotates. The bearing bears a great working pressure, so the quality of the bearing components is also very critical.



3. In the moving part, the drilling power tool holder generally has air cylinders, oil cylinders and screw rods, which are mainly responsible for the reciprocating movement of the mandrel, mainly for better sealing.



4. The shell is mainly for compact structure during production, and the gap is too large, which is easy to produce errors.



5. The quality of the pulley set is good, the effect will be relatively stable, it is not easy to deflect, and the transmission force is strong.



6. Motor, of course, the better the quality, the better the speed and torque. The above 6 components are the core components that make up the milling head of the modular machine tool. The quality of the machine tool is good or bad for the excellent performance of the driven tool holder, and then affects the performance of the modular machine tool.



The classification of boring and milling power tool holders is determined by the industrial use of the milling head, and the specific classification is the classification of CNC milling machines. CNC milling machines can be divided into the following three categories according to the classification of general milling machines: CNC vertical boring and milling heads, horizontal CNC boring and milling heads, and vertical and horizontal boring and milling. It is installed on the milling machine used to process various surfaces on the workpiece, and the planer milling. It is connected with the main shaft and used to manufacture high-precision machine tool accessories for industrial products. There are two series of milling power toolholders, XR and XRA. The XR series has four powers of 5.5KW, 7.5KW, 11KW, 15KW and eight styles; the HTX series has six powers of 4KW, 5.5KW, 7.5KW, 11KW, 15KW, and 22KW. , Twelve styles, widely used by major manufacturers of gantry milling machines, face milling machines and processing lines throughout the country.
