Technology and polishing theory

Our procedures describe the path we recommend as a safe and efficient starting point. Actual polishing may need controlled adjustment because two pieces made from the same nominal material can differ in alloy, surface condition, size, geometry and heat behavior.

Difference between the first polishing stage and finishing

In the LUXI system, the first polishing stage and the finishing stage solve different tasks. They must not be interchanged, and a finishing compound must not be expected to do the work of the first polishing stage.

Why the wheel is the working body in the LUXI system

One of the main ideas of the LUXI system is that the polishing wheel must remain the working body of the process. LUXI compound is applied in a very small amount: it activates the contact zone and helps the wheel work with the metal surface, but it must not become a thick working layer between the wheel and the item.

Where to start: understanding the LUXI system

LUXI is not simply a set of polishing compounds in different colours. It is a complete way of working with a metal surface: preparation, wheel selection, minimal application of original LUXI compound, the first polishing stage, finishing, washing and checking the result.

Logic of polishing wheel selection in the LUXI system

In the LUXI system, the wheel is the working body of the process, not just a carrier for compound. Compound is applied minimally and helps activate the contact zone, but the mechanical action, pressure, shear and heat are transmitted by the wheel.

Wheel diameter, rpm and linear speed in the contact zone

Wheel rpm by itself does not explain how actively polishing works. The same revolutions per minute can produce completely different behaviour on an 8 mm small attachment, a 102 mm wheel, a standard 152 mm wheel or a large 203 mm wheel.

Why planar items require a more active first polishing stage

Large planar surfaces polish differently from small areas of a ring, relief or edge. This is not only a question of material, and not only a question of compound selection. The main reason is the contact area between the item and the polishing wheel.

Compound chemistry and the logic of clean polishing

In the LUXI system, polishing quality is not defined only by how quickly lustre appears. It also matters what remains on the surface after polishing: a thin, stable surface layer, or a mixture of old compound, removed metal and contamination that then has to be removed for a long time.

Small tools and low-temperature polishing

In the LUXI system, not every polishing process happens under the same conditions. A large polishing wheel, felt attachment, cotton wrap, brush, thread or cord create different contact zones.

Practical knowledge base

Technology notes explain LUXI as a system: compound formulation, tool choice, sequence, washing and operator technique work together. Compound colour alone is not a universal process.
