Accurate positioning of the cutter head forward and backward and accurate self-locking function

A comprehensive solution for the operation of complex and demanding environments such as structural optimization of machine tool bearings, manufacturing accuracy, and installation and use. Composite, high-speed, intelligent, precise and environmental protection have become the material and engineering technology of the high-quality machine tool bearings for the development of machine tool industry technology, which makes the bearing have stable and excellent performance in the ultra-high speed machining process, which is the most in the field. One of the best solutions. The realization of these goals requires the cooperation of high-precision and even special-structure rolling bearings. It has a more complete product line in the field of machine tool precision bearings, covering machine tool spindle bearings, ball screw support bearings and machining center rotary tables, etc. Provides machine tool builders with a variety of precision, speed, and rigidity requirements. The optimized load capacity of the bearing series features higher limit speeds and greater dynamic radial stiffness to improve machining efficiency while maintaining excellent finished tolerance control. These improvements are attributed to the unique combination of a unique ball body and precision engineered raceway geometry. The geometry of the bearing series minimizes the effects of lubricant shear forces generated during high speed operation. This series of bearings not only has a lower operating temperature, but also comes standard. The ceramic balls included in the design can further reduce the operating temperature and improve the machining accuracy while reducing the friction of the rolling contact surface. Today's small-volume, multi-variety and efficient production mode has brought a broad development horizon. Whether it is the boring and milling machining center, the five-axis linkage machining center or the turning-milling combined machining center, it can obtain the processing capability of five or more surfaces under the conditions of high precision and high precision in CNC machining. For high-precision applications, they can withstand radial and axial composite loads and overturning moments. They are usually used in high-precision rotary tables, platforms, milling heads, rotary clamps, etc. in CNC machining centers.

The mounting holes on the bearing rings make the bearing unit easier to install, and the mounting dimensions of all series are the same. It is easy to replace the type to meet different application requirements. After the bearing is installed, the radial and axial preloading is performed. Our rotary table and rotary spindle have reliable rigidity and high rotation precision, providing the most reliable functional components for small-volume, multi-variety, high-precision and high-efficiency composite CNC machining centers. Torque motors and the like all play their respective roles in improving the overall performance of CNC machine tools. It must be acknowledged that the functional components have always been the bottleneck in the development of CNC machine tools in China, and the performance of the functional components determines the performance of CNC machine tools. However, the lag of China's functional component technology has caused China's CNC machine tool technology to lag behind some developed countries. Therefore, improving the performance of functional components is the inevitable way to improve the core advantages of CNC machine tools. As we all know, CNC machine tools have been developing in the direction of efficiency, speed and intelligence for many years. The running speed of CNC machine tools is getting faster and faster, and the load of transmission and axial transmission is also increased correspondingly, and the degree of roundness. For the screw with a pre-tightening nut in particular, the consistency and stability of its operation will be maintained to ensure a constant radial force. The fluctuation of the radial force during the operation of the ball screw will cause the oscillation of the transmission system, reducing the machine. In addition, how to improve the service life of the machine has become a hot spot. The ball screw pair is the core part of the transmission on the machine tool. The high-quality ball screw pair helps the machine to improve the life of the bed. This is an important reference factor in the selection of electrified transmissions.

Compared with the value of the whole equipment, the ball screw only has a fraction. If the machine tool manufacturer makes a "saving" article here, the negative impact of not selecting the screw on the machine tool is great. This cannot be ignored. I think that the following key factors should be considered when defining a high-quality ball screw. By optimizing the design of the track contact angle of the ball screw pair, the life of the screw can be extended by ten times. The ultimate realization of this design is based on the premise of the development of precision machining processes, in order to achieve the design of the white surface not only refers to the ball screw frame but also the nut track. In recent years, the surface finish that can be achieved has been greatly improved by the thread grinder. This year has been plagued by the constant radial force improvement in the industry, especially on the basis of strict screw production with pre-tightening nuts. The improved inverter design increases the screw speed to accommodate the high speed trend of the machine. In addition, the material of the inverter is also an aspect that cannot be ignored. How to avoid the distortion of the lead screw caused by high torque, can be solved according to the above mentioned improvement of the screw coaxiality error and the screw and nut track design structure, or the nut drive can be used for this, relying on Germany The technology developed the end-face return structure, and at the Beijing International Machine Tool Exhibition and Taiwan company launched the product of this kind of structure, which attracted the attention and attention of the peers. The structure is characterized by small torque fluctuations, low noise, especially at high speeds, and a compact space structure. This kind of structure has already been serialized by several manufacturers, which will become a development trend. Secondly, in the processing of products, we cannot use the traditional methods to take the old road of human-machine warfare and inefficiency. It is necessary to have innovations and adopt new process routes and process methods. Therefore, a machining process using hardened rotary milling followed by thread grinding is proposed and determined.

It has two meanings. One is to replace the coarse grinding of the thread grinding by hardening rotary milling, which greatly improves the production efficiency. Secondly, it can pre-produce a large number of hardened light circles and then spin milling. After receiving the order, directly use it to change the system, and finally through the thread grinding fine grinding. Together, these two aspects directly accelerate the output of the product, which is an efficient production mode, which greatly shortens the delivery time. The high-speed hardware rotary milling machine can directly screw the thread raceway to the finished product, which is a revolutionary technological breakthrough, which guarantees the processing and output of the long-length screw. Whether it is direct milling to the finished product, or as an intermediate process of rotary milling, this is a distinctive feature of our company's process. Many developments and improvements of CNC machine tools are inseparable from the improvement, improvement, development and innovation of functional components. In addition, the functional components are also an important factor in improving the cost performance and added value of CNC machine tools. Because the functional components are high-tech products, they have a high added value. The cost of the other functional components accounts for a large proportion of the total cost of a CNC machine. Therefore, the use of advanced functional components such as improved performance and reduced manufacturing costs can not only improve the cost performance of CNC machine tools, but also increase the added value of CNC machine tools and increase the economic benefits of enterprises. Our fixed or adjustable angle heads can increase the machining range and adaptability without changing the machine structure, enabling some machining that is difficult to accomplish with conventional methods, and reducing the re-clamping time of the workpiece and improving machining accuracy and efficiency. It can be used for internal machining of the cabinet structure, or it can be installed in the tool magazine of the machining center to realize free conversion between the tool magazine and the machine tool spindle. The fixed or adjustable multi-axis drilling or tapping system can greatly improve the processing efficiency and increase the production capacity of machine tools. The electric bucket magazine uses a high-performance single-phase reversible electromagnetic brake motor to advance and retract the cutter head relative to the spindle through a single cam mechanism. The tool magazine forward and backward position detection switches are installed at the left and right ends of the tool magazine components, which can accurately control the forward and backward positions of the tool magazine. The adjustment is extremely simple. Since the transmission adopts pure cam structure and the motor is equipped with electromagnetic brakes, the cutter head can be accurately realized. Precise positioning of the forward and backward movements and self-locking function can overcome the failure of the cutter head caused by accidents such as sudden power failure during the tool change.
