Feature:
1.Multi-functional storage: Available in various sizes such as 4-position, 6-position, 10-position and even 12-position, it can meet the storage needs of different consumers for multiple watches.
2.Select high-quality series motors, precisely grind the motor shaft (with a roughness Ra ≤ 0.4 μm), apply high-temperature resistant lubricating grease (with a temperature resistance range of -20℃ to 80℃), and then fix the motor stator and rotor with a special fixture to ensure the coaxiality error is ≤ 0.02mm, avoiding eccentric vibration during operation.
3.Rotating tray manufacturing: The tray is formed by cutting with ABS + PC composite material. The surface of the tray is precisely engraved with positioning grooves (with an accuracy of ±0.1mm) for fixing the watch pillow; Metal bearings are installed at the bottom (with an inner diameter matching the transmission shaft), and the bearings are connected with the tray through a hot pressing process to ensure that the radial runout during rotation is ≤0.05mm.
