Machines from Timesavers can be built to produce a variety of sheet metal finishes. Metal finishing is the last step in the manufacturing, that adds to the protection and aesthetics of the products. The most common finishes are decorative finishes as for instance a straight-line or a grain finish. These can be accomplished in finishing processes that use abrasive belts, Scotch-Brite belts and/or brushes. More information could be read in the knowledge base page about finishing.

The perfect finish with a Timesavers
Timesavers offers machines for every required finish. From the Manual Grinder, to the rotary brush machines, to the 81 series; all Timesavers machines have their unique finish capabilities. The finishes can be applied to a variety of materials depending on the machine.
Finishing of sheet metal products
There are several finishing techniques to get the perfect sheet metal surface finish that meets your surface roughness requirements. There is a wide range of finishes for stainless steels, such as the common 2d finish or a 2BA (Bright Annealed) finish that is made by brushes, or a No. 5 with a Scotch-Brite belt. The deburring machines can be equipped with a Scotch-Brite belt, to add a finish to the deburred products. When a non-directional finish is preferred, the rotary brushes are recommended.
Finishing of sheets
Every machine from Timesavers is able to produce a nice surface finish on sheet metal products, however, Timesavers has also designed three machines that are the ultimate solution for finishing sheet-to-sheet or coil-to-coil material.
This machine is the ideal solution for finishing of sheets that are produced by a cold rolling process. It ensures the best result for a stainless steel surface.
A smooth surface can be achieved with this wet ‘coil-to-coil’ line. Both, cold and hot rolled sheets can be finished by this machine. Because of the wet process, it can even handle titanium, molybdenum and zirconium.
This dry working machine produces a smooth finish on cold and hot rolled sheets. Depending on the type of brush and belt in combination with the right settings, no. 3 or 4 finish can be achieved.
Hairline adds to Rimex’s portfolio
As one of the world’s leading specialists in the production of metal sheet finishes, particularly stainless steel finishes, Enfield, Middlesex-based Rimex has constantly re-invented itself over its 60 year history. In doing so it has maintained a high profile across global markets for its range of polished, embossed and coloured stainless steel sheet products, ready for sheet metal fabrications. Rimex is capable of producing almost any finish, like hairline and even the highly reflective ones.

FAQ about finishing
Why apply a finish on metal?
A finish on metal parts is aesthetically pleasing and can reduce the surface roughness. A smooth surface is hygienic and can be a requirement for products that are intended for the food industry and pharmacy.
What finish should I apply?
Depending on the purpose of the product, a decision can be made for a (non-)directional finish that can go from dull to shiny to even highly mirrored.
What finishing technique can be used for metal parts, metal plates or coils?
A finish applied with non-woven material or rotary brushes is often used for metal parts that only need a finish for aesthetic reasons. Metal plates and coils however, require often a low surface roughness (Ra) that can be obtained by using multiple abrasive belts.
What types of metal finishes are there?
Number 0 Finish
the starting finish of hot rolled, tempered sheets.
Number 1 Finish
This is a dull and slightly rough surface, which is the starting finish on sheets of a hot rolled, tempered, etched and passivated process.
Number 2D Finish
This dull finish is superior to a No. 1 finish and is the starting finish on sheets of a cold rolled, tempered, etched and passivated process.
Number BD Finish
This is a glossy finish on sheets, due to a cold rolled, polished, tempered, etched and passivated process.
Number 2BA Finish
This is a mirror-like finish with some imperfections. BA stands for Bright Annealed, which is made in a controlled atmosphere.
Number 3 or 4 Finish
These finishes can be obtained with abrasive belts ranging from grit 120 or 180 to even 240 or 320. No. 3 is great for food processing equipment, while No. 4 is a little brighter and finer, often used for escalators, elevators and architectural buildings for example.
Number 5 Finish
A finish applied with non-woven abrasive.
Number 6 or 7 Finish
A finish of which the surface is processed with grinding compounds. With no. 7 there are additional cotton mops, which are polish compounds.
Number 8 Finish
A true mirror finish, produced on sheets with the use of discs. This process uses a mixture of abrasive compound and water to do the polishing.
Products with this type of finish can be put in every possible direction.
This finish has a long, continuous straight lines parallel to the length of the sheet metal.
A duplo finish is a finish with combination of first abrasive belt and then Scotch-Brite brush.
Is a finish applied with Scotch-Brite brushes or even Scotch-Brite belts.
Powder coating Finish
This finish makes parts that are made during CNC machining processes resistant to corrosion and aesthetically pleasing. Although it is not recommended for smaller components and internal surfaces, it is suitable for military applications or industrial equipment.
This finish removes the top-layer of a part by highly pressurized sand, thus creating a uniform and smoother surface texture.
