Ceramic Media For Disc Finishing Machine

For optimal finishing, the selection of the correct finishing machine, grinding media and compounds are of the most importance. Various parameters can influence results. The most important parameters are:

  • Quality, form and size of the grinding media.
  • Design, volume and construction of Disc-Finishing and Drag-Finishing machines.
  • Design, material and the weight of the work pieces.
  • Possibility of separation.
  • Grinding and polishing requirements.

Media is very important for the entire cleaning, deburring , smoothing and polishing process in jewelry finishing. For best finishing selection of the correct grinding, media and components are very important. For Grinding, mostly Plastic and Ceramic media is used. Steel media is used to achieve luster, mirror finish or a single stage cleaning.

Ceramic Media

Grinding media can be divided into two main groups:

  • Mainly used for the grinding of steel alloys.
  • Ceramic beads reduce contamination to products.
  • For burnishing, polishing and driving loose abrasive.
  • Good metal removal and exceptional wear Pre-forms in a wide variety of de-burr, de-flash and radius applications.

Plastic Polishing Media

  • It is used for dry polishing of jewellery especially for silver jewellery.
  • Plastic Polishing Chips are used for dry polishing of jewellery. They are especially suitable for processing swivels and other hollow items, where fragments of walnut-shell media might get stuck. They are highly recommended for silver jewellery.

Stainless Steel Media

  • Mainly for burnishing parts, but can also be used for de-burring by beating down the burrs.
  • For bright luster burnishing and de-burring of ferrous and non-ferrous parts for handling purposes where surface refinement is not critical.

Common sizes: 2.4, 3.2 and 4.0 mm. Additional sizes available upon request.

Satellites: Satellite size is SAT 3/5. Additional sizes available upon request.

Material: 1.4301 = AISI 304 , AISI 420

Walnut Shell Granule Media

  • Cleaning by walnut shell is particularly effective where the surface of the substrate under its coat of paint, dirt, grease, scale, carbon, etc. should remain unchanged or other-wise unimpaired.
  • Walnut shell grit can be used as a soft aggregate in removing foreign matter or coatings from surfaces without etching, scratching or marring cleaned areas.
  • It is an excellent replacement for sand (free silica) to avoid inhalation health concerns.
  • Mainly used for delicate parts. It will remove surface contamination, debris and coatings with little to no impact on the substrate.
  • It is resistant to break down and can be re-used multiple times in the process. And it presents no health or environmental hazards.

Polishing Paste & Compounds

  • The DELMER polishing compounds give the best finishing result. In the wet process, compounds are added to the disc Finishing machine. With the use of Compound, we get bright & clean surface of the workpieces and they do not contain any strong complexing agent.
  • In the wet process, compounds are added to the Disc-Finishing machines. During the grinding process, they provide the work pieces with a clean, bright and non-corroded surface. With impact-sensitive work pieces, the compound acts as a foam buffer from the media.
  • Dry polishing paste is used for mirror shine polishing of jewellery & other work pieces. Particularly suitable for white metals.
