Company slogan: specializing in the integration of industrial robot grinding and polishing systems OEM Overview: OEM / ODM Solutions by Zhejiang Kingstone Robot & Technology Co., Ltd.Zhejiang Kingstone Robot & Technology Co., Ltd. provides customized robotic grinding, polishing, buffing, and deburring solutions for manufacturers of brass faucets, sanitary hardware, automotive parts, metal castings, and other complex components.
Rather than offering a standard one-size-fits-all machine, Kingstone develops automation systems based on customers’ workpiece drawings, samples, material types, surface-finish requirements, production volume, and factory layout.
Its customized solution scope can include:
- Six-axis industrial robot selection and integration
- Belt grinding, sanding, cloth-wheel buffing, and polishing stations
- Custom robot grippers, fixtures, positioning, and clamping systems
- Loading and unloading worktables or conveyor integration
- PLC, touchscreen, electrical control, and robot programming systems
- Dust-collection interfaces and optional safety enclosures
- Process configuration from rough grinding to fine polishing and mirror finishing
For brass faucet applications, Kingstone can configure robotic surface-finishing lines that combine force-controlled belt grinding with cloth-wheel buffing. The system can be designed to improve surface consistency, reduce dependence on manual polishing, and support flexible production of different faucet models.
Production Line: Zhejiang Kingstone Robot & Technology Co., Ltd. specializes in automated surface-finishing production lines for brass faucets and sanitary hardware. Its systems are designed to replace manual grinding and polishing with robotic, repeatable, and controllable processing.
A typical brass faucet grinding and polishing line includes the following stages:
- Workpiece loading Brass faucet bodies are placed on a loading table or integrated conveyor system. Custom positioning fixtures secure each workpiece before processing.
- Robotic handling A six-axis industrial robot picks up the faucet body and moves it through each processing station. The system can be configured with ABB, KUKA, FANUC, or other specified robot brands.
- Belt grinding The robot guides the faucet against belt sanding machines for rough, medium, and fine grinding. Depending on the production requirement, the line can use single-station, dual-station, or four-station belt grinding machines. This stage removes casting marks, burrs, and surface defects while preparing the faucet for polishing.
- Cloth-wheel buffing and polishing After grinding, the faucet is transferred to a cloth-wheel buffing station. Kingstone’s brass faucet solution includes a six-axis, four-station CNC polishing machine that can polish four workpieces simultaneously. Cloth wheels and solid polishing wax are used to create a smooth and mirror-like surface finish.
- Automatic control and programming The line is controlled through PLC, touchscreen, electrical control cabinets, and robot programs. Teaching programming allows operators to record polishing paths, save programs, and recall them for repeated production.
- Unloading and quality inspection After polishing, the robot returns the finished faucet to the unloading position for visual inspection or subsequent quality-control processes.
The complete system can include robotic grippers, custom fixtures, loading and unloading worktables, conveyor systems, dust collection interfaces, and optional dust-proof safety enclosures. The equipment is designed to improve finishing consistency, reduce labor dependence, support flexible production, and enhance workplace safety.
