- Light-cutting grades for suitable brass burrs and edges.
- Porcelain cylinders and balls for a selected burnishing process.
- Media geometry checked against holes, recesses, and separation.
- Sample trials to establish surface quality and dimensional change.
Ceramic Tumbling Media for Brass
Ceramic grades for controlled deburring and surface smoothing of brass, with porcelain options for a separate burnishing stage. Match the media, compound, and equipment to your parts and finish requirements.
Porcelain cylinders are listed for burnishing suitable brass components after the required cutting stage. Check contact with recesses and the final surface.
Porcelain balls are listed for cleaning and burnishing. Select size, compound, and loading through trials; the result depends on the starting surface.
Finishing Compounds and Pastes
LC-13 is listed as a mild finishing compound for lubrication during processing. Confirm suitability for the brass alloy, media, concentration, and process-water system.
HM-7C-A is listed for brass polishing. Confirm the exact product designation and application instructions; the original description also referred to HM-A.
HX-0 is listed as a cleaning compound for removing process soils. Confirm concentration, rinsing, and compatibility with the brass and subsequent finishing steps.
Finishing Equipment for Brass Components
Review vibratory and rotary equipment for brass cutting or burnishing, then establish media, compound, loading, separation, and cleaning on sample parts. Send the part drawing and required output for an equipment proposal.
- Share the part material, geometry, starting surface, and target finish.
- Review the media grade, shape, dimensions, and compatible compound.
- Evaluate stock removal, marks, lodging, and separation on sample parts.
- Request a quotation for the selected grade, quantity, and delivery destination.

- Before & After
The listed service includes free sample processing. Send representative unfinished parts and a reference finish or acceptance criteria. Agree on sample quantity, shipping, evaluation scope, and return arrangements before sending the parts.
The original listed minimum is 500 kg per media type. Confirm the exact grade, size, shape, order weight, and current quotation.
Media is listed in double-layer PP woven bags of 25 kg or 50 lb, with 40 bags per pallet. These are separate packing options, not equal weights. Confirm the pallet weight and dimensions for the selected pack.
The original standard terms are a 30% advance payment and the balance before shipment. Confirm the agreed terms and inspection arrangements in the quotation. Other originally listed options include L/C, PayPal, and Western Union; confirm their availability for the order.
Shanghai and Ningbo are listed export ports. The original page also mentions Yiwu; confirm the actual inland and export route. Include your destination and delivery terms when requesting a freight quotation.
Choose Cutting and Burnishing Media Separately
Abrasive ceramic media removes material from brass surfaces. Light-cutting grades may suit small burrs, edge refinement, and surface conditioning when the alloy and geometry allow it. Porcelain polishing media is a separate option for cleaning and burnishing an already prepared surface; it is not a replacement for removing substantial burrs.
Match the Process to the Brass Component
Applications described here include machined fittings, cast parts, jewelry components, fasteners, and brass cases. Each needs its own process. Specify the alloy, starting surface, wall thickness, allowable edge radius, and dimensional limits. Copper and bronze components also require separate confirmation rather than the same settings by default.
Review Equipment and Sample Results
Review vibratory or rotary equipment, media grade and geometry, compound, load, and separation together. Inspect representative samples for burr removal, dents, scratches, trapped media, residues, and the required appearance. A bright surface alone does not prove that a part meets its functional requirements.
Request a Media and Process Recommendation
Send drawings or photographs, material, dimensions, starting surface, burr or defect condition, target finish, dimensional limits, machine details, and required quantity. Inovatec can review the media, compound, sample-processing requirements, and quotation.
Selection and Process Questions
- 1. Which ceramic grade should I use for brass?
- 2. How long should the process run?
- 3. Why do media shape and size matter?
- 4. What is a typical process sequence?

- 9. How should I compare processing costs?
1. Which ceramic grade should I use for brass?
Start with a light-cutting grade where it can remove the required burrs without exceeding the allowed stock removal. Compare it with plastic abrasive media or a separate burnishing process on representative brass samples.
2. How long should the process run?
Establish time through trials and inspect at suitable intervals. Alloy, burr size, media grade, loading, compound, and machine action all matter; a universal two-to-four-hour cycle is not a validated setting.
3. Why do media shape and size matter?
Media must reach the required surfaces and separate from the part afterward. Compare complete dimensions with holes and recesses, and test worn media as well as new media.
4. What is a typical process sequence?
Select the cutting or cleaning stage, establish the machine load and compound, then inspect the result. Add burnishing only where required, and finish with separation, rinsing, drying, and any specified protection.
5. When is ceramic media preferable to other options?
Evaluate ceramic when its cutting action, contact, and wear meet the job. It is not automatically better than plastic, steel, or natural media; compare surface quality, stock removal, separation, and total processing cost.
6. How can I protect thin brass components?
Use representative samples to evaluate dents, edge rounding, and material loss. Check loading and media contact, then inspect all recesses for trapped media. For brass cases, confirm complete internal cleanliness within the intended cleaning procedure.
7. Can I use ceramic media dry?
Confirm dry use with the specific media and equipment. Do not convert a wet process by simply omitting water; dry polishing with natural media is a separate option requiring its own settings.
8. Can the media be reused?
Reuse media while its condition, size distribution, cleanliness, and cutting performance remain suitable. Remove broken or undersized pieces and review lodged-media risks as the media wears.
9. How should I compare processing costs?
Include media consumption, compound, water, energy, labor, cleaning, separation, and waste handling. Compare the cost per acceptable part rather than purchase price or cycle time alone.
