The working theory of a centerless round pipe polishing machine
A polishing wheel rotating in high speed and together with another rotating guide wheel will make sure the round pipe automatically move forward. When the polishing wheel / abrasive wheel rub against the surface of pipe, the pipe gets polished. By changing the position of polishing wheel, you can control how much the pipe to be polished. There is plenty of different types of grinding wheels, such as sand wheel, flax wheel, cloth wheel and nylon wheel. This machine can be used for polishing stainless steel pipe, steel pipe, aluminum pipe and other metal shaft shape parts.
The guide wheel
Usually guide wheel speed is much lower like 0-45r/min, driven by 0.75kw motor and worm reducer. The speed of guide wheel will determine the speed of pipe feeding.
The material is corundum rubber wheel, because it is wear-resistant and offer bigger friction force for the pipe.
Rough polishing and fine polishing
Usually the we begin with rough polishing and end with fine polishing, we can use grit 60-300 flap wheel for rough polishing and grit 600 nylone wheel for fine polishing.
Application of pipe polishing machine
- Removing the burrs on the surface of pipe
- Cleaning the rust on the pipe
- Grinding rough pipe to get shinny pipe outer surface
- Oxide film removal
Used for below product polishing
Pipe polishing machines and metal plate polishing machines are mainly used for the following industry: wood and furniture industries such as flat wood boards, furniture metal handles and other workpieces for sanding and drawing; hardware (metal) materials and products, aluminum profiles and related products, stainless steel products and utensils, copper profiles and its products, plumbing and bathroom hardware, locks, lighting products, metal signs and nameplates, metal crafts and hand craft accessories, knives and scissors, door hinges, automobile and bicycle spare parts, tableware, buckle products, buttons, belt buckles, mobile phone casings, watch industry sanding and hairline drawing of workpieces, electronic parts, flat sheets grinding. The use of different types of polishing machines can improve the surface finish of various workpieces. Large multi-head polishing machines can polish workpieces to mirror finish with remarkable effects.
Setting for pipes in different diameter
Adjust the height of support plate of polishing machine and fix the plate, make sure the workpiece is in same centerline height as grinding wheel and guide wheel.
The guide wheel motor should start in low speed for safety reason.
To get economic result of polishing, we need to choose right distance between polishing wheel and the pipe, if the polishing wheel press tight on the pipes it will cause much more diameter reducing on the workpiece but if the polishing wheel is too far away from the pipe you will not get enough polishing.
