The working principle of the linear guide long working hours three linear guides, ball begins to wear, acting on the ball preload began to weaken, resulting in reduced working parts of the machine movement precision. If you want to keep the initial accuracy, it must be replaced rail bracket, or even replace the rail. If the rail system has been pre-load effect. System accuracy is lost, the only way is to replace the rolling elements. Design of the rail system, and strive to have the greatest contact area between the fixed element and a moving element, which not only can increase the carrying capacity of the system, and the system can withstand the impact of intermittent cutting or cutting generated gravity, the force is spread widely, expand bear force area. To achieve this, the groove shape of the rail system has a diverse, representative of two ways, one is called Gothic (pointed arch) Rubber pressure mechanical linear guide, is a semi-circular shape extending woodworking machinery linear guide, the contact point of the vertex; the other is a circular arc shape, can also play the same role. No matter what kind of structure, only one purpose, and strive for more contact with the rail rolling ball radius (fixed components). Factors determining system performance characteristics are: how the rolling element contact with the rail, which is the crux of the problem. Reliability analysis using linear guides improve the use of CNC machine tools to improve the reliability of the linear guide machine: feasibility testing and verification by the process of product design program 1. My company design and manufacture of multi-CNC machine tool is a combination of deep holes Processing of special tools. In-depth understanding of user needs, based on the construction machinery linear guide, the first of the key technologies involved in user demand - "deep hole processing technology" for the process test, process test demonstrated the feasibility of the design scheme, ensure that the design of the product to meet user needs. 2. The use of technology is mature design of modular components combination of CNC machine tools multi-station modular components of our validated by mass production, such as the use of linear motion guide CNC slide, a small power head drilling, precision CNC turret and so on. 3. lessons, lessons learned in the past to produce a combination of quality information and service tools to analyze the feedback of protection such as machine tools, wiring and other issues put forward to improve the appearance requirements. 4. Use high-quality control systems and components for machine tools use high-performance, high-reliability CNC system, servo drives, supporting the functional components, electrical components, detection devices, in order to ensure the reliability of the machine. CNC machine tools used in Japan FANUC's POWERMATE-D motion controller, which has a two-axis control function, can also control an analog / digital spindle, two servo axes can be configured in a channel can also be configured separately in two channel. System with integrated PLC, through FANUCI / OLINK serial data transfer bus can be up to 16 POWERMATE-D motion controller connected together. A plurality of motion controllers can share a CRT / MDI monitor. These characteristics make the use of distributed control system consisting of the motion controller has good scalability, especially for workers with different bits of various multi-station combination of CNC machine tools.
