Brass instruments generally use metal materials such as brass, red brass, and cupronickel. The surface coating of the instrument will fall off after being used for a long time or other accidental drops. Once it is oxidized, it is difficult to handle, especially the welding part is extremely difficult to handle. The oxidation of brass instruments affects the overall appearance, which troubles many brass instrument lovers.
So how can we make brass instruments as bright as ever? This requires polishing the surface of the brass instrument, which is an important procedure for the restoration of the brass instrument. It can restore the surface of the brass instrument to a clean and beautiful appearance.
Commonly used polishing method for the surface of brass instruments—–mechanical polishing
Mechanical polishing is a commonly used polishing method for brass instruments, because the wall thickness of brass instruments will not be affected by the mechanical polishing process, nor will it affect the timbre of brass instruments, so the loss of brass instruments can be minimized.
When the brass instrument is mechanically polished, the surface of the instrument is polished on a high-speed rotating polishing machine after adding polishing liquid compounds to the polishing wheel. At this time, high temperature is generated due to friction, which deforms the surface of the polished brass instrument and forms a layer of processed deterioration. Under the action of rotational friction, on the one hand, some convex parts on the surface are cut off, and at the same time, the surface of the brass instrument will also be plastically deformed. The convex parts are pressed in or moved for a certain distance and then filled into the concave parts.
Repeat this process and the surface of the brass instrument can be restored smooth and bright under the bright effect of the polishing liquid compounds.
Application examples of brass instrument polishing
Jiangmen Makeraze Technology Co., Ltd. uses the century-old Makeraze brand technology in polishing and other surface treatment technologies. We provide customers with various surface treatment solutions and high-performance materials for a long time. The following is the polishing solution provided by Jiangmen Makeraze Technology Co., Ltd. If you have any needs, please feel free to contact us.
The following polishing plan was given by Makeraze for the common “French Horn” in brass instruments. Please contact Jiangmen Makeraze Technology Co., Ltd. for the polishing consumables mentioned in the polishing process.
There are three types of polishing processes for the surface of brass instruments, namely rough polishing, medium polishing, and fine polishing. The “French Horn” is polished by using a hard cloth wheel with special treatment by Makeraze and polishing compound D-6229 yellow stick. The rough polishing and middle polishing can be done on the cloth wheel at one time. It can not only save polishing time but also provide high-quality gloss. In the fine polishing process, a soft cloth wheel or woolen wheel and polishing compound R30-10 red stick can be used for the final refinement of the “French Horn”, which can finally achieve a mirror effect and restore the beauty of the instrument.
After the above-mentioned polishing treatment, the rusty brass instrument can also be restored to its original beauty.
