The application of the external cylindrical grinder
The external rounding polishing machine is primarily used in the metalworking, vehicle parts, steel and wood furniture, instrument machinery, standard parts, and electroplating industries for rust removal and polishing. It is the ideal choice for polishing round tubes, round bars, and slender shafts. The workpieces processed by the round tube polishing machine have high luster without affecting their original dimensions, making it particularly suitable for the high-luster polishing of workpieces after centerless grinding.
Features of the external cylindrical polishing machine
The round tube polishing machine boasts high work efficiency, excellent surface roughness of workpieces, and stable performance. The machine features variable frequency control for the guide wheel speed (optional).
Therefore, regardless of the workpiece diameter and length, a more ideal processing efficiency can be achieved.
The ZJ series centerless external cylindrical polishing machine (grinding machine) was independently developed by our technical team in response to market demands in 2001. It features easy operation, the option of various grinding tools, and more. This machine is primarily used in industries such as hardware, electroplating, steel and wood furniture, standard parts, automotive and motorcycle accessories, etc. It is suitable for external surface polishing and grinding of various shafts, rods, and pipe components; ultra-long stainless steel tubes, boiler tubes, high-precision tubes, titanium alloy bars; hydraulic rods for construction machinery, shock absorber rods for cars and motorcycles, valve rods, oilfield oil-pulling rods; and polishing and grinding of various metal/non-metal rods, pipes, plastics, rubber tubes, spinning machine rods, and various types of wire materials.
