Classes of metal processing

Are you interested in processing classes of metals, steels and alloys from the supplier company AvecGlob? Here you will find interesting information on this topic.

Classification

Depending on its purpose, products made of metals and alloys have a different quality of processing their surface. An objective indicator that characterizes this quality is the processing classes that determine the surface structure of the product, its continuity, tightness, the indices of operational durability and aesthetics of perception. The processing class is usually evaluated by the roughness index. It is a quantity that sets the height of the surface irregularities and the frequency of their alternation. The surface roughness is measured in micrometers, for which purpose special instruments are used — profilometers and profilographs.

For each specific conditions of use, the product has its own optimal processing class

Urgency of application

Standardized indices of the surface treatment class are used in the design of units and parts of machines and devices for developing the best technological process for their production

Supplier — AvekGlob Company — offers at reasonable prices from the manufacturer of billets from various metals and alloys processed to the required classes, in the quantity and range required by the customer. The supplier guarantees the timely delivery of products to any address specified by the consumer

Selecting a processing class

GOST provides for four groups that characterize the class of processing of metals and alloys:

Rough, in which surface defects can be recognized visually. Such a class is formed as a result of surface treatment by a large file, by a gas-flame jet, by rough metal-cutting tools; Defects of the surface are visible to the naked eye, their cause was the processing of a large file by hand or the use of drills, cutters and cutters in the initial penetration of machine tools;

received. The roughness of such a surface is also discernible to the naked eye, but with close scrutiny. Such a surface is formed when machining with semi-finished files, as well as with a metalworking tool with large feeds and low cutting speeds;

clean. Roughness can be detected only when examining the surface in a microscope. It turns out such a surface during finishing processing with cutters, grinding or hand tools;

very clean. Such a surface is considered a reference, and is used in the manufacture of high-precision tools, instruments, jewelry.

Supplier — AvekGlob Company — offers to purchase products from various metals and alloys, obtained by different classes of processing, in any quantity and in a nomenclature of sizes. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
