This workflow describes three independent polishing routes for platinum. Select the route according to abrasive preparation, actual surface condition, item geometry, and the required character of contact. The routes are alternatives and do not form one mandatory chain.

Before any route begins, complete the item geometry, required repair, and even abrasive preparation. Deep scratches, cracks, open cavities, unfinished shape correction, and other defects that polishing must not correct should be resolved first.

Route 1 — LUXI Black → LUXI Pink

Use this route after even platinum preparation to approximately P800–P1000 when a strong first stage is required.

LUXI Black must fully remove the visible marks from the last abrasive and form an even surface while preserving edges, relief, and geometry. Select the LUXI Black working tool from its product-specific card according to contact area and item shape. This shared workflow does not prescribe one universal wheel for every platinum item.

Before changing to LUXI Pink, remove all LUXI Black and removed metal, clean the surface, allow it to cool, and inspect it under directed light. Move to finishing only after the first stage has been fully completed.

Use LUXI Pink on a separate clean white unstitched Calico wheel. For a wheel approximately 150 mm in diameter, use 2500–3000 rpm as the working starting range. For another diameter, select the operating conditions according to linear surface speed, contact area and stability, temperature, and the behaviour of the particular alloy.

Route 2 — LUXI Gray → LUXI Pink

Use this route after finer and even platinum preparation to approximately P2000–P3000.

LUXI Gray must fully remove the visible marks from the last abrasive and leave a surface ready for finishing. Select the LUXI Gray tool according to its product-specific card and the actual task. The confirmed data do not establish one universal cotton-fabric family for LUXI Gray, so Calico, muslin, or another fabric name must not be inserted automatically.

After the LUXI Gray stage has been completed, clean the surface fully and use LUXI Pink on a separate clean white unstitched Calico wheel. LUXI Pink must not be used to correct marks from an incomplete first stage.

Route 3 — independent two-wheel LUXI Green

LUXI Green may perform an independent two-wheel platinum route without a mandatory transition to LUXI Pink.

Use LUXI Green first on a firmer stitched wheel. This stage must fully remove the visible marks from the last abrasive and form an even surface. Then remove all compound and removed material, clean and cool the item, and inspect the result.

Use the same LUXI Green next on a separate clean softer unstitched wheel until the required lustre and uniform reflection are achieved.

The exact fabric families of the two LUXI Green wheels are not established in the confirmed data and must not be invented. No universal abrasive grade is assigned to this route; select preparation according to the actual platinum surface, tool, and required result.

For a standard wheel approximately 150 mm in diameter under ordinary conditions, 2500–3000 rpm may be used as the starting range according to the LUXI Green product card. Do not transfer this range automatically to another diameter. The deliberately reduced range around 1000 rpm belongs to separate confirmed low-temperature branches for titanium and sufficiently thick coatings; it is not the standard setting for this platinum route.

Shared operating rules

Use a separate clean tool for each compound and each stage. Apply compound according to the product-specific loading rule and do not create a thick layer of compound and removed metal between the wheel and the surface.

Work in short passes, keep the item moving, and control pressure, temperature, and wheel condition. Do not compensate for insufficient preparation with excess compound, increased pressure, or prolonged continuous contact.

After every stage, remove compound and removed material completely, allow the item to cool, and inspect the surface under directed light. Continue only after the previous stage has been confirmed complete.

Completion criterion

Polishing is complete when the fully cleaned, dry, and cool surface shows:

  • no visible marks from the last abrasive or previous stage;
  • an even reflection appropriate to the selected route;
  • no dull zones, contamination, or compound in recesses;
  • preserved edges, relief, and intended geometry;
  • a stable result after cleaning and cooling.

Stop conditions

Stop if the process produces:

  • noticeable overheating;
  • waviness or loss of flatness;
  • edge loss or relief smoothing;
  • increasing haze;
  • unstable lustre after cooling;
  • opened or growing pores, cracks, or cavities;
  • changes in a coating or unknown surface layer.

These conditions require a return to preparation, repair, or production-suitability assessment rather than an automatic increase in compound or pressure.

Cleaning and coatings

Select the cleaning method for the whole item: material, construction, stones, inserts, joints, coating, and next operation. LUXI iClean, ultrasonic cleaning, heated solution, solvent, and steam are not prescribed automatically.

Do not mechanically polish a thin decorative, protective, electroplated, or PVD coating that must be preserved. Identify an unknown coating first. A sufficiently thick and stable layer permits only a separate test-based assessment on a sample or non-critical area; a successful general test does not create an automatic recommendation for one of the platinum routes.
