In modern mechanical transmission parts gear (gear precision machine tools Machine) is the most widely used. Our production of precision machine tools machine tool gear durable, high efficiency, fast speed and other characteristics.

Here are the introduction of precision machine tools machine gears:
Modern Mechanical Gear is one of the most widely used mechanical transmission parts. Gear space to pass any motion and power between the two shafts through teeth engaged with each other, and you can change the form and speed of movement. Wide gear range, the transmission ratio constant, high efficiency, long life. In the mechanical parts of the product design and manufacturing process, not only to consider the properties of the material to adapt to the working conditions of parts, the parts durable, and require materials with better processing performance and economy, in order to improve the productivity of parts, reduce costs and reduce consumption.
