1. It can carry 8 racks, and the whole machine can be equipped with up to 480 metal eyeglass frames (proven stainless steel hangers to avoid deformation of the frame) Reduced polished corners) 2. When the hanger rotates along with the drum, it can rotate independently and improve the polishing efficiency. 3. Intelligent PLC operation control of the hanging device positioning system, perfect implementation of the hanging number and positioning start operation, improve efficiency and reduce costs. 4. Bamboo fiber: The density of bamboo fiber drum is higher than that of traditional wood material, which reduces the use of rolling oil.
