As we all know, since the mid-20th century, humans have begun to pursue high processing efficiency, and at the same time require high-speed, high-precision, high-rigidity and high-reliability CNC machine tools. In recent years, globally, numerically controlled machine tools have been proposed to reduce environmental pollution and reduce noise. New energy-saving concepts such as energy saving and space saving, new technological trends in modern CNC machine tools with parallel mechanism, compounding, multi-functionalization and engineering intensification, speeding up one machine for simultaneous grinding, turning and milling, multi-faceted multi-axis The development of processing technology.
The high reliability of high-speed, composite, intelligent and environmentally-friendly modern CNC machine tools is the key to success, while the LM linear rolling system (rolling guide pair, ball screw pair, ball spline pair) with steel ball spacer technology It is a key feature of the top priority. The LM linear rolling system of the steel ball spacer technology is to separate the rolling elements by a retainer, and the retainer between the steel balls forms a bag shape, so that the lubricating oil can be left for a long period of time to achieve long-term lubrication-free.
The connecting belts on both sides of the retainer make the rolling bodies serially connected, eliminating the phenomenon that the rolling direction and the speed of the rolling elements of the all-steel ball type are inconsistent, and achieving the sensitive response when the micro-motion is achieved, and the follow-up can be improved. Minimize the quadrant protrusion during circular interpolation, obtain high-precision contour machining accuracy, eliminate friction between steel balls, prevent heat and wear, and greatly reduce the variation of rolling resistance. Compared with the previous all-steel ball type, the linear motion speed is increased by 1.6 times, and the ultra-high-speed linear motion of 300m/min (5m/s) can be realized.
Functional design of modern CNC machine tools While pursuing high efficiency and high precision, mechanical environmental protection is also an important factor that must be considered. In terms of high efficiency and high precision, the LM linear rolling system shows excellent motion characteristics. Based on this, LM Guide Pair, Ball Screw Pair, QZ Self-lubricating Device for Ball Spline Pair and LaCS Layered Contact are developed. A series of environmentally friendly accessories such as dustproof devices for boards. More than a dozen Chinese CNC machine tool manufacturers have adopted the LM Guides application examples of these environmentally friendly accessories, and I believe that they will further accelerate the speed of popularization in the future. THK's LM linear rolling system contributes to the environmental protection of the global machinery industry, accelerates the research and development of new products, and contributes to the international competitiveness of machinery manufacturing companies that use these new technologies for new machine development.

Auxiliary motor refers to the motor used to drive various auxiliary machinery on the locomotive. Such as fan motor, air compressor motor, oil pump motor and so on. Dc motor or asynchronous motor is usually used.
Diesel locomotive generally uses dc motor, powered by diesel engine driven DC auxiliary generator. Induction motors are commonly used in electric locomotives, powered by split cameras or inverters.
