The application of the external cylindrical grinder
The external round polishing machine is primarily used in the metal products, vehicle parts, steel and wood furniture, instrument machinery, standard parts, and electroplating industries for rust removal and polishing. It is the preferred choice for polishing round pipes, round rods, and slender shafts. The workpieces processed by the round tube polishing machine have high luster without affecting their original dimensions, making it especially suitable for the high-luster polishing of workpieces after centerless grinding.
Characteristics of the External Round 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's diameter or length, a relatively 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 and 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 polishing and grinding the external surfaces of various shafts, rods, and pipe components; ultra-long stainless steel tubes, 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; as well as polishing and grinding of various metal/non-metal rods, pipes, plastics, rubber tubes, spinning machine rods, and various types of wire materials.
