China's machine tool industry is developing rapidly and improving. The development of the machine tool industry is due to the continuous application and promotion of new automation technology in the machine tool industry, in terms of basic technology, design and manufacturing processes, high-end technology and new functional development. Great progress has been made. The CNC system is the core of CNC machine tools and the brain of CNC machine tools. The faster and stronger CNC system enables CNC machine tools to have more powerful calculation and processing capabilities, enabling more complex and detailed machining.
Compound processing is a new way to transform and upgrade CNC machine tools
The compound function makes the CNC machine tool significantly improve the production speed of the finished workpiece. Today's machining tends to be high-precision, multi-variety, small batch, low-cost, short-cycle and complicated processing. Composite machining is an important part of CNC machine tools. The direction of technology development. The many advantages of composite machining will be more widely used in automation products and technologies on machine tools.
High-speed and high-precision is not only the speed of machining of workpieces by CNC machine tools, but the precision of the products produced is higher. It also requires high-speed operation and precise positioning of CNC machine tools in the whole process of workpiece machining to reduce workpieces. In the preparation, processing, transshipment, storage and other aspects of the occupation, improve the production efficiency of the plant and reduce production costs. Higher precision mechanical products will bring more benefits in practical use, such as reducing friction and heat during operation, reducing energy loss, making the whole machine run more smoothly and reliably, and reducing the probability of failure. In order to achieve the goal of high speed and high precision, automation product manufacturers have increased their technical investment and development efforts, and developed more automation products for CNC machine tools, such as linear motors, electric spindles, higher line encoders, and more precision. Highly stable grating scales, etc. These automation products provide powerful support for high-speed and high-precision functions of CNC machine tools.
The compound function makes the CNC machine tool significantly improve the production speed of the finished product, which can greatly eliminate the transportation, clamping and waiting time during the processing of the hashing process, which greatly shortens the processing cycle and reduces the number of products in the processing workshop. The workpiece has only one clamping position on the machine tool, which reduces the machining assistance time and improves the machining accuracy of the workpiece. Obviously, multi-tasking machines require more automation products. The implementation of composite functions relies on real-time detection and intelligent judgment, data calculation, tool management and system control for workpieces and tools. Automated products and technologies such as high-sensitivity probes, high-speed processing chips, smaller sensors, and faster response sensors and actuators will find wider application on machine tools.
Today's machining is more oriented to high precision, multi-variety, small batch, low cost, short cycle and complicated processing. Composite machining is an important technical development direction of CNC machine tools. CNC machine tools should have and communicate with voice, graphics, video and text. Through the sharing of network information, the production planning and scheduling department can monitor the working status and processing progress of the machine in real time.
(Finish)Box Guideway Machining Centers
Box guideway machining center also call hard rail machining center in China, it refers to a casting part where the guide rail and the bed are integrated, and then the guide rail is processed on the basis of the casting, which is a type of hard guide rail. The shape of the guide rail is cast on the bed, and then processed into a guide rail through quenching and grinding. The hard rail used in the hard rail machining center is generally a rectangular structure, commonly known as a rectangular guide rail or box guide rail. The Box way machining center machining center adopts sliding friction, which leads to a larger contact surface and high rigidity and strength. Therefore, the box guideway machining center is more suitable for heavy-duty cutting and is suitable for heavy-duty mold processing.
Advantages of box guideway Machining Centers:
1. Able to withstand larger loads, suitable for rough machining machines with large cutting amounts and large feed rates.
2. Due to the large contact area of the guide rail, the machine tool operates more smoothly, making it suitable for factories with high requirements for machine tool vibration.
Disadvantages of box guideway machining centers:
1. Shorter service life. Under the same maintenance and usage conditions, the service life of box guideways is generally shorter than linear guide machining center, because box guideways operate with sliding friction, while linear guide operate with rolling friction, resulting in greater wear and tear.
2. The repair cost is too high. The maintenance of box guideway machining center is much more difficult and costly than linear guideway machining center. If there is insufficient scraping allowance, it may involve disassembling all the large parts of the machine tool, performing quenching and mechanical processing again, and even more importantly, recasting the large parts. The wire gauge only needs to replace the corresponding linear guide, which will not greatly affect the use of related large parts.
3. The running speed of machine is low, and box guideways machining center usually cannot withstand too fast running speed due to their movement mode and the excessive friction they bear, which contradicts the current machining concept to a certain extent. Especially many factory workers do not have the corresponding maintenance knowledge for machine tools. Many times, they only know how to use the machine tool, but largely neglect the maintenance of the machine tool. The maintenance of the machine tool track is of utmost importance. Once the lubrication of the track is insufficient, it can cause the track to burn or wear excessively, which is fatal to the accuracy of the machine tool.
