The multi-circle tube polishing machine adopts the principle of non-center grinding, which consists of two mechanisms: polishing and feeding. By adjusting the feed amount of the grinding head, the workpiece can be ground or finely ground and polished by adjusting the spacing of the guide wheels. The HL-3 type round tube polishing machine with different specifications can be processed. The feeding mechanism of the machine adopts a stepless speed change device, which can achieve the ideal grinding and polishing effect by changing the feed speed of the workpiece. According to the different materials and polishing requirements of the workpiece, the polishing machine can be used to polish the workpiece by using various polishing tools such as abrasive cloth wheel, hemp wheel, cloth wheel and nylon wheel. The workpiece holder is made of wear-resistant material and can be adjusted without frequent adjustment. When the workpiece specification is changed and adjusted, the machine adopts the structure of “one-way moving in two-way positionâ€, which greatly simplifies the pallet adjustment work. The complete production line consists of three parts: polishing machine, feeding device and discharging device. There are various models such as standard type, automatic type, environmental protection type and economy type for users to choose. The number of heads of the main machine can be specified according to the original condition of the surface of the workpiece and the finish of the surface of the finished product.
