1. Overview
The XYD-CNC (JY-CNC) CNC dished end polishing machine is a fully automatic system
designed for polishing concave metal heads, end caps, and vessel ends
with high efficiency and precision.
Engineered for elliptical surfaces made of stainless steel, carbon steel,
and alloy materials, the machine integrates servo control,
automatic pressure adjustment, pneumatic self-centering clamping,
and a fully enclosed visible safety cover.
It is widely applied in pressure vessel manufacturing,
food-grade tank production, and pharmaceutical equipment finishing,
delivering stable and repeatable high-quality surface results.
