Function of the main spindle: The main spindle is the core rotating axis of the equipment, usually directly driving the tool (such as milling cutter, drill bit) or workpiece to rotate, completing cutting, polishing and other machining tasks.
High speed, high precision, usually driven directly by a motor or through a belt/gear.
The function of the secondary shaft (auxiliary shaft) is to assist the driven shaft of the main shaft and support complex machining. Usually linked with the spindle control, the speed and steering can be independently adjusted. Commonly used in automation equipment to reduce workpiece replacement time.
Damping Bar/Resistance Rod vibration reduction: reduces vibration during high-speed rotation of the tool shaft or auxiliary shaft, improves machining accuracy. Buffer: absorbs impact in the robotic arm or linear guide rail (such as at the end of cylinder stroke). Speed regulation: Adjust the speed of moving parts (such as stamping equipment) through hydraulic/pneumatic resistance
