Why is copper hard to grind ?
Copper has good ductility, it is easy to cause blockage of pores, and the grinding wheel loses heat dissipation capacity, which in turn causes burns or expansion and deformation of the workpiece, which is one of the materials that are difficult to grind.
The main processing properties of copper are as follows:
1.The grinding wheel is easy to block, and the workpiece is heated and deformed.
Due to the good ductility of copper, it is easy to block the pores and lose the heat dissipation capacity of the grinding wheel, which will cause burns or expansion and deformation of the workpiece.
2.Copper materials are easy to stick, grind, slip, and vibrate.
After grinding, the copper material is easy to adhere to the abrasive grains, so that the abrasive grains lose the grinding force and easily leave vibration marks on the workpiece.
3.Easy to scratch, difficult to improve gloss
After grinding, the copper material is easy to adhere to the surface of the grinding wheel, causing scratches as the grinding wheel rotates, and it is not easy to increase the gloss.
Solution direction: Add more stoma in the griding wheel or use the electroplate plating diamond wheel.
