The dynamic balance accuracy of the Guanshuo’s China Machine tool spindle motor shaft spindle reaches G0.1 - G0.4. After precise correction through weight reduction or weighting, it is suitable for ultra-high-speed operation above 10,000 RPM, without resonance or micro-vibration, meeting the procurement and operation standards for ultra-high-speed cutting of machine tools. The mating surfaces are treated with ion nitriding, vacuum carburizing and quenching, and CVD/PVD hard coating. The surface hardness reaches HRC60-65, resistant to particle wear and instantaneous cutting impact, with a roughness of Ra0.012-0.025 μm, reducing the friction loss of the mating surfaces. Supports solid or hollow shaft design, capable of processing conical surfaces (BT30/BT40/BT50), splines, and threaded connection sections. The shaft shoulder positioning accuracy is ≤0.001mm, suitable for seamless direct connection of machine tool spindles with chucks and tool holders, meeting the requirements of customized assembly and procurement.
