Temperature rise of the spindle
Understand the heating state of the entire spindle! Significantly improve quality and reliability in long hours of continuous processing.
The temperature rise of the spindle is primarily caused by friction heat from the bearings during high-speed rotation, the agitation of the lubricant, and heat conversion by the motor. Excessive temperature rise can lead to displacement or thermal deformation of the spindle shaft, adversely affecting machining accuracy, surface finish, and tool life. To ensure stable operation of the spindle over long periods and consistency in machining, precise control of temperature rise and thermal compensation mechanisms are extremely important. Generally, the temperature changes at three key positions are monitored: the fixed end of the bearing (T1), the movable end (T2), and the spindle motor (T3). [General Standards for Spindle Temperature Management] ■ Temperature rise at the bearing section ΔT ≦ 20°C ■ Temperature difference between T1 and T2 ≦ 5°C *For more details, please download the PDF or feel free to contact us.

Our company was established in 1977, starting with the development of dedicated machines. As we progressed with in-house development, we deeply recognized the importance of spindles. In 1998, we introduced repair and manufacturing technology for high-frequency spindles from Europe, and in addition to repairing these high-frequency spindles, we have also been engaged in the research and development of built-in high-speed spindles. With the management philosophy of "Quality First," we aim to enhance our customers' competitiveness by continuously developing high-quality built-in high-speed spindles. Additionally, in addition to mass production, we provide specialized services for machine tool manufacturers with specific needs for built-in high-speed spindles, including design, development, assembly, and testing.
