1. Product Overview
The XYD-2 CNC Dish Head Grinding & Polishing Machine from Xinyida is designed for high-precision polishing of stainless steel
cylinders, cones, and dish heads, covering both internal and external surfaces.
It is especially suitable for pressure vessel and sanitary-grade applications.
The complete machine consists of a cross-beam main unit, polishing head assembly, cooling circulation system,
electric control panel, pneumatic components, and a heavy-duty workpiece turntable.
The CNC system drives the beam and column to move horizontally and vertically, guiding the grinding head to accurately
follow the curvature of the workpiece. Combined with servo-controlled spindle rotation,
this ensures excellent surface conformity and stable, consistent polishing results.
