How to remove burrs and oxide scales from hardware wrenches tools and achieve a mirror polishing surface?
Hardware wrench tool deburring,descaling and mirror polishing process technology method
Hardware tools are necessities in our daily production. The name of hardware originally refers to tools made of five metals: gold, silver, copper, iron, and tin. However, with the development of technology today, the materials used in hardware tools have long broken through the original five metal limitations and are changing with each passing day. Today we will share a case of deburring and descaling of an open-end wrench tool product made of chrome-vanadium alloy steel after stamping, reducing surface roughness, and mirror polishing. This finishing process solution is also suitable for the deburring, descaling, mirror finishing and polishing of hardware wrench tools made of other materials such as high-carbon steel, stainless steel, and high-manganese alloy steel.

5. Additional instructions
- Chrome vanadium steel is an alloy tool steel with chromium (CR) and vanadium (V) alloy elements. Its comprehensive strength and toughness are better than carbon steel, making it an ideal material for high-quality tools. This product is small in size and requires high finishing efficiency. Therefore, the rough finishing machine uses a centrifugal disc finisher, which has strong finishing force and high cutting efficiency. The medium-cutting force of the angle cut tri-angle ceramic tumbling media is used for rough finishing, which can achieve the effect of rapid deburring and descaling.
- Fine finishing uses light cutting force plastic media, also called polyester media. This tumbling media has small grit size and light weight, will not cause deformation of the workpiece, and can further reduce the surface roughness.
- The last step after fine finishing is to use a mirror polisher and mirror polishing abrasive media to enhance the brightness and mirror polishing.
6. Final summary
- In this case study, we demonstrate the process of automated deburring, descaling, mirror finishing and polishing of the outer surface of a chrome-vanadium alloy steel hardware wrench tool.
