Product Description
The CNC Polishing Machine is an advanced automatic surface finishing system designed for high-precision grinding and polishing of various metal components. Equipped with a CNC control system and multi-axis motion technology, it enables accurate tool movement, consistent polishing pressure, and uniform surface finishing.
The machine is widely used for polishing stainless steel tanks, cookware, sanitary ware, hardware components, automotive parts, and other metal products that require high-quality surface treatment. It can achieve smooth, bright, and mirror-like finishes while significantly improving production efficiency and reducing manual labor.
1. Product Overview
The CNC Industrial Polishing Machine is engineered for automated surface finishing of large cylndrical tanks anddished heads ranging from Ø1000mm to Ø5000mm. It features a precision CNC control system, high-efficiency variablefrequency polishing head, and heavy-duty rotary table. The equipment supports multiple polishing processes, including brushed finish and mirror polishing, ensuring high surface quality with consistent results
Constructed with a robust base, column, horizontal beam, dual polishing heads, and integrated control cabinet, the machine offers full-axis automation, high adaptability, and reduced manual labor
