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.

Metal material hafnium parts polishing and deburring process technology method

How to automatically and quickly chamfer, deburr and polish small hafnium parts?

Metal materials include carbon steel, general-purpose alloys such as aluminum alloys, stainless steel, zinc alloys, etc.; and high-purity elemental metals, such as gold, silver, copper, aluminum, hafnium, gallium and other metals; high-purity precision alloy materials such as aluminum-copper alloys , molybdenum and niobium alloys, etc.; precious metals & rare metals such as titanium, iridium, tungsten, etc.; and rare earth metals such as cerium, gadolinium, lanthanum, etc., in the shapes of plates, coils, rods, pipes, wires, grain, blocks, ingots, Powder etc. To obtain a satisfactory surface effect, do you know what kind of finishing and polishing process is required for the burrs, flash, and scale produced after metal materials are cast, forged, rolled, drawn, pierced, stamped, sheared, etc. ? In this case, we will share the process solution for chamfering, deburring, and descaling and polishing the surface of metal hafnium parts. This polishing process is also suitable for surface polishing of other hard metal products.

5. Additional instructions
  • Because this hafnium product is a small-sized workpiece with high hardness, it requires strong cutting force to chamfer, deburr and remove scale. Therefore, the rough finishing process is using high-speed centrifugal barrel finishing machine, with heavy cutting force ceramic deburring ball.
    The precision finishing and polishing brightness also uses a centrifugal barrel finishing machine, with high hardness and light cutting force white corundum polishing ball to improve surface brightness.
  • Because the number of products processed is small, product separating can be done manually using screens to reduce equipment purchase costs.
  • In order to improve the anti-rust and anti-corrosion performance of the product after being exposed to water, a centrifugal spin dryer used for drying.

6. Final summary
  • In this case, we demonstrate a process for surface chamfering, deburring and polishing of parts machined with metallic material – hafnium.
  • This process is also suitable for surface polishing of other hard metal material processing parts.
