Superhard material laser cutting diamond product parts deburring, descaling, smoothing and polishing technology method

How to deburr, descale, smooth, finish and polish the superhard material laser cutting diamond product parts?

Diamond is a single crystal composed of regularly arranged carbon atoms. After cutting, finishing and polishing, diamond becomes a collectible diamond. Diamond is the simplest of all gemstones and the hardest substance naturally existing in nature. With this physical property, diamond is also widely used in the industrial field. Today we will share a case study of finishing and polishing a small slice of diamond synthetic material. Since the workpiece is processed by laser cutting technology, this polishing process method is also suitable for deburring, descaling, chamfering and polishing other precision machining parts of superhard materials such as plasma, water jet, wire cutting.

5. Additional instructions
  • This superhard diamond material part is a small precision product, so the rough finishing and polishing machine uses a centrifugal barrel finisher, which has strong finishing force and high cutting efficiency. Diamond is a superhard material with high hardness, so the tumbling media uses silicon carbide abrasives media with higher cutting force than heavy-cut ceramic deburring media, which can achieve the effect of quickly removing burrs and oxide layers.
  • Fine polishing uses precision finishing and polishing abrasives media with light cutting force and small abrasive grain size to further reduce surface roughness.

6. Final summary
  • In this case, we demonstrated a process for automated deburring, serrated edges smoothing, descaling, chamfering and polishing of the outer surface of a laser-cut superhard diamond component.
  • If you need professional technical support for deburring, descaling, chamfering and polishing of precision hardware accessories, workpieces or the following products such as plasma, water jet, wire cutting, etc., you can refer to the above cases:

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.
