Spindle Thermal Expansion Compensation System
In the field of high-speed and high-precision machining, built-in spindles have become a key trend in modern machine tool design due to their compact structure and direct-drive power transmission. However, with the motor integrated inside the spindle body, prolonged high-speed operation generates significant heat, causing thermal elongation of the spindle shaft. This thermal deformation can compromise dimensional accuracy, surface quality, and overall machine stability.
