Angled triangular pieces offer flat surfaces and corners for contact with accessible part features. Choose dimensions from the openings and separation system, then select the cutting grade for the required operation.
Straight-cut triangles are a common profile for surface cutting and edge work. Their action depends on the material formulation, part geometry, and machine movement.
Angled cylinder ends can help reach selected recesses. Test the complete profile against openings to avoid pieces entering a feature that they cannot leave.
Straight cylinders combine flat ends with a rolling curved surface. Evaluate the contact pattern and verify that their length and diameter suit the part and separator.
Tristar profiles can offer access to certain details that a simpler shape cannot contact effectively. Check the actual dimensions; the profile alone does not establish coverage or a shorter cycle.
Larger tristar pieces may suit applications with sufficient clearance and approved loading. Balance the contact action against part impact, machine capacity, and separation requirements.
Wedges offer a combination of contact faces for selected flats and channels. Confirm access, lodging risk, and wear behavior on the actual workpiece.
Elliptical pieces are an option for curved surfaces and accessible details. Select the dimensions and cutting grade independently, and verify removal from recesses after processing.
Balls provide a rounded contact profile. An abrasive ceramic ball and a non-cutting steel ball have different functions despite sharing the same shape.
Conical plastic media combine flat and curved contact surfaces. Match the resin-bonded grade to the required stock removal and check the resulting surface texture.
Tetrahedral profiles provide multiple faces and points for accessible features. Assess contact with critical edges and monitor fragments or worn pieces that could become trapped.
Plastic tristar pieces offer a shaped resin-bonded medium. Trial their contact pattern, cutting behavior, and separation with the intended machine and batch.
Finishing Media Grades and Material Options
The VFC grade is intended for applications requiring substantial abrasive cutting. Compare stock removal, edge rounding, media wear, and part damage in a trial before selecting it.
An abrasive grade for deburring and surface cutting. Evaluate the balance between removal rate, finish, wear, and cycle time for the actual component.
GC is a general-cutting grade for suitable deburring, cleaning, and surface preparation tasks. Confirm the formulation and the removal needed rather than treating the grade name as a universal application rule.
The MC medium-cutting grade can be evaluated for stone-aging and surface-texturing applications. Verify the required texture, dimensional change, and compatibility with the actual stone or component.
An option where controlled cutting and smoothing are required. Confirm the effect on soft alloys and critical edges, including any downstream coating requirements.
A low-cut option for suitable surface refinement and brightening processes. Confirm the precise grade, compound, and initial surface condition; not every ceramic medium is a polishing grade.
A resin-bonded cutting option for appropriate stock removal and surface preparation. The required texture for painting, plating, or anodizing should be agreed and checked after a trial.
A resin-bonded grade for suitable deburring and smoothing tasks. It can form part of a multi-stage method, but a ceramic-to-plastic sequence is not required for every part.
A choice for controlled edge work and smoothing on suitable components. Specify the desired finish rather than assuming that light cutting produces a mirror surface.
A grade for fine surface preparation. Assess it against the initial texture and the requirements of the next polishing, plating, or coating operation.
The Z1 grade is an abrasive resin-bonded medium. Confirm the exact grade specification and compare cutting, surface condition, and wear with representative parts.
The RPM chromium corundum formulation is intended for abrasive deburring. Request the grade specification and establish cutting behavior on the actual material instead of relying on a general claim about faster removal.
A granular porcelain option for suitable surface refinement and accessible details. Confirm its cutting characteristics, size distribution, and separation from holes or recesses.
High-density media are an option for suitable superfinishing processes. Media density alone does not establish an isotropic finish; select it as part of a defined machine, compound, and inspection method.
A ceramic ball option for suitable contact-finishing applications. Confirm the zirconia grade, size, wear, and chemical compatibility; it is not a universal substitute for steel media.
Pins can contact selected details in suitable finishing processes. Check pin retention and separation; magnetic polishing requires a pin grade that responds to the machine’s magnetic field.
A non-abrasive option for suitable burnishing and cleaning processes. Confirm machine loading and the effect on the part surface; steel balls do not perform abrasive stock removal in the same way as ceramic cutting media.
Shaped steel pieces can provide contact with selected surfaces and details. Verify access, lodging, surface impact, and separation rather than assuming that the shape cannot become trapped.
Machine and Process Compatibility
Vibratory bowls and troughs, rotary barrels, and centrifugal machines produce different media movement and contact conditions. Confirm the machine’s permitted media, loading, and separation arrangements. Develop any wet process with the appropriate compound, drainage, and rinse stages, and include drying or further finishing where the part requires it.

What is finishing media?
Finishing media are consumables that contact workpieces in a mass finishing process. Abrasive grades remove material, while other grades are selected for burnishing, polishing, cleaning, or drying. These functions should be distinguished when choosing the process.
How should the media range be classified?
Classify media by its actual function, material formulation, cutting grade, shape, and size. Ceramic and plastic grades can differ widely within the same family. A material name or color alone does not establish the finished surface.
Where do natural media fit?
Walnut shell and corn cob are examples of natural carriers used in suitable dry-polishing, cleaning, or drying processes. Their performance depends on the carrier grade, any approved additive, the machine, and the component. They are not substitutes for every abrasive cutting grade.
What are manufactured finishing media?
Preformed ceramic, resin-bonded plastic, porcelain, and shaped steel media are examples in the listed range. Their formulations and geometry are selected for different contact actions. Request the exact grade rather than treating all manufactured media as equivalent.
What is the difference between cutting and burnishing?
Cutting media use abrasive action to remove material and alter the surface or edges. Burnishing media act primarily through contact and pressure on a suitably prepared surface. Burnishing is not a substitute for removing deep marks or substantial burrs.
How does the machine influence the result?
The machine creates relative motion between parts and media. Its permitted load, energy, movement, and separation arrangement affect contact and throughput. A grade accepted in one machine or batch should not automatically be transferred to another without review.
Which selection factors should be reviewed?
Consider material, incoming texture and burrs, required stock removal, edge condition, dimensions, holes and slots, media wear, compound, and separation. Define acceptance checks before a trial so the choice is based on the finished part.
Is there one best finishing medium?
There is no single best grade for every component. Choose the medium that reaches the required surfaces, meets the finish and dimensional limits, and separates reliably at an acceptable process cost.
Which operations can media support?
Suitable processes include deburring, edge rounding, smoothing, burnishing, and cleaning; separate media may be required for drying or final polishing. Define the sequence from the incoming part and required result rather than assuming that one grade performs every stage.
How should shape and size be chosen?
Select dimensions from feature access, lodging risk, contact, and separation. Include media size changes through wear and any fragments. Larger and smaller pieces each have tradeoffs; neither size alone guarantees a faster cycle or a finer finish.
How long does finishing media last?
Service life depends on the grade, machine, process conditions, and part. Track wear, shape change, cutting behavior, contamination, and separation. Steel, ceramic, and plastic media should not be assigned a universal lifespan or a zero-wear guarantee.
How is the media-to-parts ratio established?
Develop the load within the machine’s approved capacity and review part contact, circulation, finish, and separation in trials. State whether a ratio refers to volume or mass. A fixed ratio cannot be applied to every geometry, material, and machine.
