Purpose of the external cylindrical polishing machine
The external cylindrical polishing machine is primarily used in industries such as metalworking, vehicle accessories, steel and wood furniture, instrument machinery, standard parts, and electroplating before and after processes 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 them particularly suitable for 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 of the guide wheel speed (optional), ensuring optimal processing efficiency for workpieces of varying diameters and lengths.

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 is easy to operate and features the option of various grinding tools. 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; super-long stainless steel pipes, boiler pipes, high-precision pipes, titanium alloy bars; hydraulic rods for construction machinery, shock absorber rods for automobiles and motorcycles, valve rods, and oilfield sucker rods; polishing and grinding of various metal/non-metal rods, pipes, plastics, rubber tubes, spinning machine rods, and various types of wire materials.
