Cutting of rolled metal, steel and alloys

Are you interested in technology and equipment for cutting rolled metal, steels and alloys from the supplier company AvecGlob? Here you will find interesting information on this topic.

Classification of metal cutting processes

Distinguish the technology of mechanical cutting, in which there is the formation of metal waste in the form of chips, cutting metals by shear (plastic separation of parts of the workpiece) and cutting with the use of high energies (anodic-mechanical, electromechanical, electric arc, gas-flame and plasma cutting).

Urgency of application

Mechanical cutting is used at high initial requirements for the accuracy of the cut workpiece (in particular, the cut surface parameters). Such cutting does not differ appreciable productivity, and it is used in serial and single production. In mass production, the technological operations of shearing are used, under which the plastic shearing of one part of the metal occurs relative to the other. Such a technology is non-waste, however, it does not differ in high accuracy of cutting, and the cross-section of the cut piece is distorted. High-energy cutting methods are mainly used for brittle metals and alloys.

Supplier — AvekGlob Company — offers at affordable prices from the manufacturer various metals and alloys, blanks for which can be obtained using various cutting processes. The assortment and the number of such blanks are completely determined by the customer’s wishes. The supplier guarantees the timely delivery of products to any address specified by the consumer

Equipment

For mechanical cutting of metals and alloys, the following are used:

Lathes and automatic machines (provide the highest quality of the separation surface, but they are distinguished by large losses of metal in the chips);

Friction and circular saws (with high quality cuts are not used for materials with high hardness due to the danger of reflows of the ends of the billet);

Band saws and mechanical hacksaws (they have low productivity, but are easy to manage and maintain).

When cutting by shear, we use sheet (guillotine) scissors, combined shears, press shears. The first ones are used for cutting sheets and strips, the latter for cutting profile rolls (angles, channels), and the third for cutting bulk metal (rods, wires). Such equipment is characterized by high productivity, therefore it is used in mass and large-scale production in the form of automated complexes.

The construction also uses disk shears for cutting roofing rolls, as well as cutting machines designed for cutting pipes.

In a single production, cutting machines are used that produce the separation of the metal by a jet of gas, liquid or other working medium (for example, an abrasive), using a high speed of its movement. The advantage of all the processes of high-energy cutting of rolled metal is the lack of an expensive and fast-wearing working tool — saws, knives, punches, etc.

Supplier — AvekGlob Company — offers to purchase various metals and alloys, blanks for which are obtained with the help of various cutting technologies. The quantity, accuracy and dimensions of the blanks are determined by the customer’s wishes. 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.
