The SUNPASS Winding Mat Outer Ring Milling Machine is specifically designed for the precision milling of the outer rings of metal wound gaskets. This advanced machine utilizes an air pump for pressure control and a frequency converter for speed adjustment, eliminating the need for costly lathes. It enables a single operator to manage multiple units simultaneously, significantly reducing labor and financial costs. Capable of milling halos with diameters exceeding 150mm, this equipment is not restricted by size specifications. The incorporation of integrated guide rods addresses issues related to space height and enhances ease of transportation.
