5 Decisions Before Your Surface Is Finished
Define the finish your buyer and receiving team can actually compare.
01
Your Material
Grade, original texture and prior processing.
02
Your Appearance
Brushed, satin or reflective sample target.
03
Your Direction
Visible faces and grain orientation.
04
Your Geometry
Critical fits, edges and accessible areas.
05
Your Acceptance
Viewing, measurement, cleaning and packing.
Choose the Finish Around Your Visible Assembly
Metal brushing services and mechanical polishing services need different surface decisions. Select your part, then review the grain, access and final acceptance that matter to your assembly.
Match Your Enclosure Finish to Its Visible Faces
For polishing aluminum enclosures, separate visible covers from hidden interiors, connector seats and mating edges.
| Your function | Cover faces, joints, connector seats and assembly datums. |
|---|---|

Resolve 8 Surface-Finish Risks Before Processing
Review the features that control your appearance, remaining material and final assembly fit.
Mark Your Grain on the Installed Part
A brushed metal finish needs a defined direction on each significant face. Include installed orientation and the adjacent surfaces that must visually match.
| Your input | Direction arrows, visible zones and installed view. |
|---|---|
| Our review | Feasible grain continuity and transition boundaries. |
Review Marks Before Trying to Remove Them
Machining marks, scratches, pores and weld transitions affect the result. Removing a deep defect may exceed the material allowance; polishing is not a repair for every underlying condition.
| Your input | Starting surface, defect limits and finish reference. |
|---|---|
| Our review | Preparation, sample feasibility and allowed removal. |
Keep Your Finished Dimensions in Control
Mechanical polishing removes material. For critical bores, sealing faces and datum pads, agree exclusions or protection and inspect the finished feature. Never substitute a zero-change promise for a measurement plan.
| Your input | Final dimensions, datums and removal limits. |
|---|---|
| Our review | Route, protection and feature-specific inspection. |
Preserve the Edges and Shape Your Assembly Needs
Finishing can round edges or affect thin and unsupported features. Define the acceptable edge condition, flatness and areas that need careful handling.
| Your input | Edge requirements, wall geometry and flatness. |
|---|---|
| Our review | Feasible support, access and finished shape. |
Separate Reachable Faces from Hidden Recesses
Tools do not reach every internal corner or narrow pocket in the same way. Mark the required finish zones and agree transitions rather than assuming identical appearance everywhere.
| Your input | Required areas and accessible geometry. |
|---|---|
| Our review | Tool access, exclusions and sample transitions. |
Agree the Remaining Weld Geometry
Review the cosmetic target alongside structural requirements. Confirm what may be blended, the remaining weld or wall requirements and the finish direction on neighboring faces.
| Your input | Weld requirements, appearance and material allowance. |
|---|---|
| Our review | Permitted blending and transition acceptance. |
Define the Surface After Abrasives and Compounds
Review abrasive or polishing-compound residue, contamination control, cleaning and the next coating, bonding or assembly step. A shiny appearance does not prove cleanliness.
| Your input | Residue limits, material segregation and next process. |
|---|---|
| Our review | Cleaning scope, handling and required evidence. |
Use One Agreed Basis for Appearance Acceptance
Specify viewing conditions and a controlled sample. Review grain, reflectivity and visible marks separately from roughness measurements, then protect the accepted surface during delivery.
| Your input | Master sample, viewing conditions and packing needs. |
|---|---|
| Our review | Inspection method, change approval and protection. |

What information is needed for a metal polishing quote? Include these inputs and distinguish part supply, mechanical finishing, subsequent coatings and final inspection responsibilities.
Answers Before Your First Order
What is a brushed metal finish?
It is a mechanically produced surface with a visible grain or texture. Define the direction, significant faces and appearance reference on your drawing; the finish name alone does not specify all acceptance requirements.
Brushing vs polishing: which fits your part?
Review the intended appearance and function. A directional brushed or hairline metal finish differs from a more reflective polished target. Agree a representative sample and required measurements instead of relying on the name alone.
Polishing vs buffing: are they the same scope?
The terms can describe different stages or methods in a finishing route. Specify the material, starting surface and required delivered result, then confirm the actual process and acceptance with your quotation.
Does polishing change dimensions?
Mechanical finishing removes material and can affect edges and critical fits. Define final dimensions, removal limits and exclusions, then verify the finished features that control your assembly.
Can polishing remove machining marks?
Some marks may be reduced, while deeper marks or defects may remain or require too much removal. Review the original surface, allowed material removal and representative sample before committing to the result.
How to specify brushed finish on a drawing?
Mark visible faces, grain direction relative to a controlled feature, transition limits and the approved appearance basis. Add roughness parameters, units, locations and inspection conditions where they are required.
Can brushed finishes be matched?
Review the actual substrate, original finish, direction and reference sample together. Agree the viewing conditions and acceptable variation on a representative part; an exact match should not be assumed from a photograph.
Does mirror finish guarantee low roughness?
No. A mirror polished finish describes appearance, while surface roughness needs a defined parameter, measurement location and method. Specify both when both matter to your application.
Mechanical polishing vs electropolishing: are they interchangeable?
No. Mechanical polishing uses physical surface finishing; electropolishing is an electrochemical route. Review substrate, geometry, function and required evidence before selecting or combining processes.
How to protect polished parts during shipping?
Agree separators, compatible film or protective packing, handling and cleanliness requirements. Confirm that the chosen protection will not leave unacceptable residue or damage the accepted surface.
How much does metal polishing cost?
Starting condition, geometry, treated area, target appearance, sample approval, inspection and packing affect cost. Compare the same scope and separate any setup or lot charges.
How long does metal polishing take?
Confirm the actual route, sample approval, processing schedule and delivery with your quote. There is no universal lead time or metal polishing minimum order for every project.
