How to polish stainless steel beautifully and without rust

TinTa stainless steel polishing methods

Mechanical polishing is a stainless steel polishing method that relies on cutting and plastic deformation of the material surface to remove polished protrusions to obtain a smooth surface.

How to polish stainless steel beautifully and without rust. Usually people use oil stone sticks, wool wheels, sandpaper... and mainly manual operations, to polish stainless steel beautifully and without rust.

Special parts such as the surface of the rotating body can be used. Use rotary table and other auxiliary tools, and super-precise polishing method can be used if the surface quality is high.

How to polish stainless steel beautifully and without rust.

Ultra-precision polishing is the use of special abrasive tools, which are tightly pressed on the processed surface of the workpiece in a stainless steel polishing solution containing abrasive grains to rotate at high speed.

Using this technology, a surface roughness of Ra 0.008 μm can be achieved, the highest among various stainless steel polishing methods .

This method is often used in optical lens molds of TinTa's custom stainless steel polishing factory.

Main advantages of stainless steel polishing processing method

Chemical polishing. Chemical polishing is to make the microscopic protrusions on the surface of the material in a chemical environment dissolve in priority over the concave parts. How to polish stainless steel beautifully and without rust, to get a smooth surface.

The main advantage of this stainless steel polishing processing method is that it does not require complicated equipment, can polish workpieces with complex shapes, can polish many workpieces at the same time, and is highly efficient.

The core problem of chemical stainless steel polishing is preparing the stainless steel polishing solution. The surface roughness obtained by chemically polishing stainless steel is typically a few 10 μm.

This technology is without the need for complicated equipment

Electrolytic stainless steel polishing . The basic principle of electrolytic stainless steel polishing is the same as chemical stainless steel polishing , which is to selectively dissolve tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better. The electrochemical polishing process is divided into two steps: (1) The macroscopic balance of the dissolved products diffuses into the electrolyte, and the geometric roughness of the material surface decreases, Ra> 1 μm. (2) Anodic polarization balances weak light, improves surface brightness, Ra <1 μm.

Ultrasonic machining process at TinTa factory

Ultrasonic stainless steel polishing . Place the workpiece into the abrasive suspension and place them together in the ultrasonic field. Based on the vibration of ultrasonic waves, the abrasive is ground and polished on the surface of the workpiece. The ultrasonic machining process at TinTa stainless steel polishing factory has small macroscopic forces and will not cause workpiece deformation, but it is difficult to manufacture and install tools.

How to polish stainless steel to make it beautiful and rust-free.

Ultrasonic treatment, how to polish stainless steel beautifully and without rust, can be combined with chemical or electrochemical methods.

Stainless steel polishing process .

On the basis of corrosion and electrolysis of the solution, ultrasonic vibration is applied to stir the solution, so that the dissolved products on the surface of the workpiece are separated, and the corrosion or electrolyte near the surface is copper. best; The cavitation effect of ultrasonic waves in liquids can also inhibit corrosion and facilitate surface brightening.

Polish stainless steel with liquid .

Fluid stainless steel polishing relies on high-speed flowing fluid and the abrasive particles it carries to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet machining, liquid jet machining, hydrodynamic grinding, etc.

Hydrodynamic grinding stainless steel polishing process

Driven by hydraulic pressure to make the liquid medium carrying abrasive particles flow back and forth across the surface of the workpiece at high speed. The medium is mainly made of special compounds (polymer-like substances) that flow well under lower pressure and mixed with abrasives. Abrasives can be made of silicon carbide powder.

Magnetic grinding and polishing of stainless steel .

Magnetic grinding and polishing of stainless steel is the use of magnetic abrasive grains to form grinding brushes under the effect of a magnetic field to grind the workpiece. This method has high processing efficiency, good quality, easy to control processing conditions and good working conditions. Using suitable abrasives, surface roughness can reach Ra0.1 μm.

Polishing the stainless steel surface is 1k bright

Mentioned in plastic mold machining is very different from surface polishing in other industries, to be precise, mold polishing should be called mirror machining. It not only has high requirements for polishing but also has high standards for surface flatness, smoothness and geometric accuracy. Polishing stainless steel surfaces usually only requires a 1k bright surface.

Standard mirror surface stainless steel polishing treatment

Divided into four levels: AO = Ra0.008 μm, A1 = Ra0.016 μm, A3 = Ra0.032 μm, A4 = Ra0.063 μm, due to electrolytic stainless steel polishing, liquid stainless steel polishing and other methods other.

Polishing the stainless steel surface is usually only required

It is very difficult to accurately control the geometrical accuracy of parts, how to polish stainless steel beautifully and without rust, and the surface quality of chemical stainless steel polishing, ultrasonic polishing, and magnetic abrasive polishing. Calculation and other methods cannot meet the requirements, so the processing of stainless steel mirror surfaces of precision molds is still mainly mechanical polishing.
