Metal surface polishing technology with introduction
Metal polishing is a finishing method that uses an abrasive material to smooth surfaces. When polished, the surfaces of metallic objects are freed of defects and become more reflective and shiny, enhancing their appearance. Metal polishing can be complemented by buffing, a less harsh method that results in a brighter finish.
Aside from its cosmetic value, metal polishing also serves a practical purpose. Beneath the surface, it removes oxidation from and prevents further corrosion of a metal, significantly prolonging its working life.
Metal polishing can be performed with several varieties of abrasive. The best abrasive for it largely depends on the condition of the material that will be polished.
If the material is unfinished, polishing will consist of several stages. During the first stage, a rougher abrasive that removes imperfections from the material is used. Finer abrasives that leave the material relatively unmarked are used in subsequent stages.
To achieve a mirror-like finish, polishing and buffing compounds are usually applied with polishing wheels and high-speed polishers. While some polishing materials can be applied as-is, wax, kerosene, and other lubricants can also be used during the process. To achieve an even brighter shine, buffing can be performed with the aid of stationary polishers, die grinders, or specialized automated equipment.
In the case of softer metals like brass, a very fine, copper-plated grit is used to smooth out marks from impurities. An airflow mop is used to buff these metals.
Because of their unique requirements, certain tools such as chisels, hammers, screwdrivers, and wrenches are subjected to a different polishing process. The same is true for knives and cutlery.
Tools initially require roughing using a grinding wheel. The materials are then finished using dry polishing materials. If an extra fine polish is necessary, greasing is also performed on the materials. Similarly, knives and cutlery require fine or blue glazing.
Depending on the strength of the metal, different types of abrasives may be used during polishing.
For low-tensile strength metals such as aluminum, brass, and copper, gray silicon carbide abrasives are used. The same type of abrasive is used on gray iron and cemented carbide, among other metals.
For high-tensile strength metals such as alloy and carbon steel as well as iron and nonferrous alloys, white and grey aluminum oxide abrasives are preferred. Ferrous metals such as steel require green chromium oxide abrasives.
Canvas and leather are ideal for polishing wheels, although a wide variety of other materials, including cotton cloth, felt, leather, paper, plastic, sheepskin, rubber, and wool can also be used. Cotton or wool cloth are used for buffing wheels or mops.
Polishing is a necessary stage in many manufacturing processes. Architectural metal, cookware, kitchenware, metal automobile parts, and handrails are just some of the products that are polished before they reach the market. In other cases, metals can be polished as part of general repairs or restoration.
Polishing and buffing can also contribute to workplace safety. Buffing, for example, helps prevent corrosion in specialty plumbing. When applied to pipes found in dairy and pharmaceutical plants, it also destroys bacteria or mold and prevents corrosion, thus ensuring product safety.
Polishing brings out the shine in metallic surfaces and improves the performance of many essential products. At BAOZHEN we’re proud to offer the finest polishing services for every metal used in modern manufacturing. From aluminum to titanium, we have the expertise needed to polish your metals according to your exact specifications.
There are many reasons why metal polishing services are needed for precision metal components. The gleaming finish provides a high-end look to resulting metal components, including those made for home appliances, automobiles, and decorative objects, and many other consumer and industrial applications. The metal polishing process uses abrasion polishing compounds to remove surface imperfections and create a uniform grain preparing the part surface for inspection and surface finishing such as anodize, paint, plating and buffing.
Industries that utilize metal polishing services include, but are not limited to:
Aerospace and defense
Commercial and residential cookware or kitchenware
Metal Polishing Benefits & Advantages
Industrial polishing services offer many benefits and advantages for products, such as:
Corrosion resistance. Metal polishing creates a surface that resists rust and corrosion.
Aesthetic appeal. Metal polishing restores shine to a previously polished finish or creates a new, improved appearance with a mirror-like gleam.
Enhanced chemical resistance. Polishing protects the metal from the damaging effects of chemicals.
Easy to clean. A polished surface prevents adhesion of food, dirt, insects, or other contaminants that can become attached to metal, making it very easy to clean.
Enhanced efficiency. Since there is no added step of stripping bare metal before polishing, the process is more efficient.
Metal Polishing Capabilities
metal polishing services accommodate many types of metals and alloys, including:
300 series stainless steel. This metal typically contains at least 10.5% chromium, as well as nickel and molybdenum. 300 series stainless steel is the most commonly used alloy used in stainless steel polishing services. It has a non-magnetic, crystalline structure that has inherent resistance to cracking, etching, and corrosion. It also maintains its strength under high temperatures.
400 series stainless steel. 400 stainless steel is a cost-effective stainless steel option when compared to 300 series stainless steel. This magnetic metal typically contains chromium and manganese.
Carbon steel. Carbon steel is made up of 0.12% to 2% carbon. It is strong, cost-effective, recyclable, and highly durable.
Aluminum. Aluminum polishing services accommodate many types of aluminum alloys. It is malleable, corrosion resistant, and has a low density. Aluminum is ideal for applications where reduced weight is important.
Inconel. This high-nickel alloy contains variable quantities of chromium and iron. It is desirable for use in high heat, high-pressure applications.
Hastelloy. This nickel alloy is known for its high corrosion resistance, chemical resistance, and thermal stability.
Titanium. While it shares many characteristics with aluminum, titanium has a higher strength-to-weight ratio. Titanium has a higher tensile strength than steel but comes at a higher price.
Copper. Copper and copper alloys are naturally antimicrobial, corrosion resistant, excellent conductors of heat and electricity, easy to work with, and fully recyclable.
Bronze. This strong alloy contains tin and copper. It is corrosion, friction, and temperature resistant and is often added to wood or other metals as a decorative accent.
Brass. Brass is a copper and zinc alloy that adds superior malleability and ductility with lower friction. It is highly sought after for musical instruments, decorative accents, and architecture.
