The transmission system is one of the crucial core components of the SMTCL CNC

The transmission system serves as the carrier for the movement of machine tool components, directly impacting machining accuracy. In China, machine tool enterprises rely on external procurement for spindles and lead screws, accounting for approximately 15% to 20% of the total cost.

The machine tool spindle is one of the most critical core components of CNC machine tools, integrating high speed, high precision, high efficiency, and high reliability. The level of its technical advancement and the quality of its performance directly determine and influence the overall quality of the machine tool.

The spindle is divided into two categories: mechanical spindle and electric spindle. Mechanical spindles generally require bearings with P4 or higher precision levels. Electric spindles, on the other hand, represent an integration of cross-industry technologies, including precision manufacturing, bearing technology, motor speed control, and rely on imports for power ratings exceeding 40KW.

In China, the Luoyang Bearing Research Institute is the most representative in the domestic electric spindle industry, while private enterprises like Haizhi Electromechanical have gained a significant share in the 3C CNC engraving and milling electric spindle market by replacing imported products.
