Metal production today has become a high-tech and a complex process of manufacturing of metal products.There are various technological methods and techniques to obtain both standard parts and blanks, and original piece goods on unique drawings.Mainly used manual or automatic processing of metal products on special machines.Below we describe the main methods of metalworking.
first class of methods involves working with metal without removing material.It is a set of methods, which is designed for rough work on the workpiece.These include stamping, extrusion, rolling, forging, and others.Typically, after preparatory manipulation with the material produced metal cutting, which allows you to obtain the required shape of the product, the required class of roughness and the size you want.
most popular and effective type of metal-processing is by means of special machines with the removal of material.This helps to form a complex of methods in one or more approaches the final version of the product.Usually it made lathe or milling turning, which is based on the rotational energy or drilling, allowing to obtain either expand the hole in the workpiece.This procedure helps to create standard parts.
also can be used grinding, used to impart a desired level of metal surfaces roughness, planing and creating a certain form of the product.And finally, the most technologically sophisticated method of processing metal with removal of material - a change of pressure based on the property of plasticity.Under certain conditions, the metal blanks are able to change their shape without breaking the structure.
under pressure can be carried out drawing, stamping, forging, rolling, and some other procedures.The quality of the material is increased, the surface becomes more smooth, enhanced lifespan.This method allows you to create both custom-made products for unique drawings and standard parts (for example, manufacturing is performed under pressure springs).Metal is processed in cold condition or heated.
Often, to get the product with the necessary parameters, the right size, it is necessary to subject it to several procedures metals (cold forming is one of these procedures).If the parts involved in creating more than one machine, such treatment is considered to be universal.
