Material:

Pig iron forgings

Apparance:

oxide scales and burrs

Shape:

S-shaped curve

Size:

300*7mm

Pre-polishing process:

Pig iron forging.

Post polishing process:

Finished or electroplated.

2. Requirements for finishing and polishing
  • The surface is smooth and burr-free.
  • Remove surface oxide scale.
  • Reduce surface roughness, increase gloss, and improve brightness.
3. Details of the finishing, polishing, deburring and descaling process for motorcycle parts (starter lever, starter rod, spark lever)
Process steps （1） Coarse finishing to remove burrs and scale （2） Fine polishing （3） Drying

5. Additional information
  • Because the motorcycle starter lever accessories are made of pig iron forgings and the material is very hard, ceramic media with heavy cutting force is used to roughly remove scale and burrs. In order to fully finish the corners of the parts or the toothed inner wall of the inner ring, the shape of the ceramic media is a chamfered cylindrical tumbling deburring media, and the smooth curve of the cylinder itself can have a smooth surface on the starting rod. Smoother polishing effect. It should be noted that if the starting rod is made of aluminum forgings, then our tumbling finishing media cannot use ceramic media, but needs to use softer materialResin media (also called plastic media).
  • These motorcycle parts are not afraid of hitting each other, so in order to improve the screening efficiency, the finishing machine uses the vibrating bowl finisher with separator.
  • Iron workpieces are easily oxidized again when exposed to water and air. Therefore, we need to dry the water immediately after finishing and polishing.

6. Final summary
  • In this case, we demonstrate the process of deburring and descaling on the surface of a forged motorcycle workpiece, also called a starter lever, starter rod, and spark lever, and further improving the surface gloss and brightness.
  • This process is also suitable for polishing parts and components such as automobiles, bicycles, fishing gear, pumps and valves, sewing machines, equipment and tooling produced from forged iron.
