How to polish and wax stainless steel

Question 1: How to polish stainless steel. Currently, the commonly used polishing methods are as follows: 1.1 Mechanical polishing. Mechanical polishing is obtained by cutting and plastic deformation of the material surface to remove the polished convex parts. Polishing methods for smooth surfaces generally use oilstone strips, wool wheels, sandpaper, etc., and are mainly manual operations. For special parts such as rotary surfaces, auxiliary tools such as turntables can be used. For those with high surface quality requirements, ultra-precision grinding and polishing methods can be used. . Super-precision polishing uses special abrasives, which are pressed against the surface of the workpiece to be processed in a polishing fluid containing abrasives to perform high-speed rotation. Using this technology, a surface roughness of Ra0.008 μm can be achieved, which is the highest among various polishing methods. This method is often used for optical lens molds. 1.2 Chemical polishing Chemical polishing allows the microscopic convex parts of the surface of the material to be dissolved preferentially in the chemical medium than the concave parts, thereby obtaining a smooth surface. The main advantage of this method is that it does not require complex equipment, can polish workpieces with complex shapes, and can polish many workpieces at the same time, with high efficiency. The core issue of chemical polishing is the preparation of polishing fluid. The surface roughness obtained by chemical polishing is generally several 10 μm. 1.3 Electrolytic Polishing The basic principle of electrolytic polishing is the same as that of chemical polishing, which is to selectively dissolve the tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, the influence of cathode reaction can be eliminated and the effect is better. The electrochemical polishing process is divided into two steps: (1) Macroscopic leveling. The dissolved products diffuse into the electrolyte, and the geometric roughness of the material surface decreases, Ra > 1 μm. (2) Glimmer smoothness, anodic polarization, improved surface brightness, Ra < 1 μm. 1.4 Ultrasonic polishing: Put the workpiece into the abrasive suspension and place it together in the ultrasonic field. Relying on the oscillation of ultrasonic waves, the abrasives grind and polish the surface of the workpiece. The macro force of ultrasonic processing is small and will not cause deformation of the workpiece, but the production and installation of tooling is difficult. Ultrasonic processing can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to stir the solution to separate the dissolved products from the surface of the workpiece and make the corrosion or electrolyte near the surface uniform; the cavitation effect of ultrasonic waves in the liquid can also inhibit the corrosion process and facilitate surface brightening. 1.5 Fluid polishing Fluid polishing relies on high-speed flowing liquid and the abrasive particles it carries to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods include: abrasive jet machining, liquid jet machining, fluid power grinding, etc. Fluid power grinding is driven by hydraulic pressure, which causes the liquid medium carrying abrasive particles to reciprocate across the workpiece surface at high speed. The medium is mainly made of special compounds (polymer-like substances) that have good flow properties at lower pressures and mixed with abrasives. The abrasives can be silicon carbide powder. 1.6 Magnetic grinding and polishing Magnetic grinding and polishing uses magnetic abrasives to form an abrasive brush under the action of a magnetic field to grind the workpiece. This method has high processing efficiency, good quality, easy control of processing conditions, and good working conditions. Using appropriate abrasives, the surface roughness can reach Ra0.1 μm. The polishing mentioned in plastic mold processing is very different from the surface polishing required in other industries. Strictly speaking, the polishing of molds should be called mirror processing. It not only has high requirements for the polishing itself but also has high standards for surface flatness, smoothness and geometric accuracy. Surface polishing generally only requires obtaining a bright surface. The standards for mirror processing are divided into four levels: AO=Ra0.008 μm, A1=Ra0.016 μm, A3=Ra0.032 μm, A4=Ra0.063 μm. Due to the difficulty of electrolytic polishing, fluid polishing and other methods It is difficult to precisely control the geometric accuracy of parts, and the surface quality of chemical polishing, ultrasonic polishing, magnetic grinding and polishing methods cannot meet the requirements, so the mirror processing of precision molds is still mainly based on mechanical polishing. 2.1 Basic procedures of mechanical polishing To obtain high-quality polishing results, the most important thing is to have high-quality polishing tools and auxiliary products such as oilstone, sandpaper and diamond abrasive paste. The choice of polishing procedure depends on the surface condition after preliminary processing, such as machining, EDM, grinding, etc. The general process of mechanical polishing is as follows: (1) Rough polishing. The surface after milling, EDM, grinding and other processes can be polished with a rotating surface polisher or ultrasonic grinder with a speed of 35,000-40,000 rpm. Commonly used methods include using a wheel with a diameter of Φ 3mm and WA # 400 to remove the white spark layer. Then there is the manual grinding of the oilstone... >>

Question 2: How to wax the stainless steel polishing machine. After the rotation starts, rub the wax with the felt piece, and the moving position can be applied evenly.

Question 3: What is the most convenient way to wax stainless steel and make it brighter? For stainless steel waxing, you can only use German stainless steel special car wax called Paite crystal wax. This car wax is a special bright wax for marble, stainless steel, chrome plating and other metals. The more you use it, the brighter it will be, and it can remove dirt and oxidation on stainless steel.

Question 4: How to polish stainless steel into a mirror surface? To put it simply: the stainless steel 8K mirror surface is made by selecting stainless steel 2B or BA or 2B light as the base material, and adding ground red powder through a grinder to grind the 8K mirror panel.

But the most important thing for 8K mirror panel is three steps. First: Choose the advantageous stainless steel plate as the base material. (Currently 201 prefers BA and L1 high nickel. 304 high-quality Zhangpu) Second: Choose a good machine and adjust the grinder master. Third: It must be carefully protected during moving and transportation.

At present, everyone should be familiar with the precision-ground 8k mirror stainless steel plate. Precision ground 8k mirror stainless steel plate, that is, stainless steel mirror panel. However, stainless steel mirror panels are subdivided from K numbers: 6K, 8K, 10K, 12K and other K numbers. If we distinguish from words, there are: general grinding, fine grinding (medium fine grinding, high requirements fine grinding) and super fine grinding. What we are currently talking about is the finely ground 8K mirror in the middle.

In fact, to put it simply, a precision-ground 8k mirror stainless steel plate is: a mirror plate with no grinding head, no blisters, and no scratches. Of course, it is understandable that you understand it this way. But if you look at it from a professional perspective. This can only be said to be one-sided, and some board patterns also need to be eliminated.

Question 5: What are the methods for polishing stainless steel parts and how long does it take? Method: Magnetic deburring polishing machine, magnetic grinding machine, magnetic deburring uses the power of the magnetic field to guide the abrasive material (magnetic needle) to rotate rapidly to grind the workpiece to achieve efficient deburring (front edge), surface polishing, brightening, It has abrasive effects such as cleaning, removing oxide films, removing sintering marks, and removing rust.

Question 6: Is there any way to polish stainless steel without waxing? It can be very beautiful even with waxing, polishing or polishing and pickling.

Question 7: How to polish stainless steel with very slight scratches? In other words, toothpaste.

For a more powerful method, add aluminum oxide abrasive paste to wool felt. For coarse grinding, you can use water sandpaper to grind step by step according to the grade of first coarse and then fine. Finally, polish with chromium oxide W7 or W5 polishing paste. Ra can reach Less than 0.1.

Question 8: How to weld stainless steel without polishing? Polishing takes up a lot of time. 100 points Stainless steel welding, polishing, and waxing are cumbersome processes that are time-consuming and low-efficiency.

Currently, there is a weld bead processor on the market,

combined with a special cleaning fluid. Welds can be processed quickly.

Question 9: What is the difference between car waxing and stainless steel waxing? Waxing is slightly abrasive. It can deal with small debris and fill small cracks. The paint surface will look shiny and polished. A layer of paint will be worn off the surface, which will cause damage to the paint surface. It is not recommended to use it frequently. If waxing is not enough, just throw it away once.

Question 10: Can stainless steel watch cases be polished? Stainless steel watch cases should not be polished by waxing. Waxing is to form a wax protective film on the surface of the object. It will not adhere to the surface of highly polished stainless steel. Evenly. Moreover, after dust adheres to the watch case, the reflectivity and color will look very unnatural. The wax spots attached after repeated waxing are difficult to remove, which greatly affects the appearance of the watch.

Additionally, all highly polished metal objects...
