Cutting iron - how to cope with impregnable material ?

Drilling iron - feature operation

most important primary products of iron and steel, cast iron, are widely used in various spheres of the global industry.They serve as starting material for the production of steel are used in mechanical engineering.Being known for more than three millennia, this metal today reflects the level of industrial development of the countries producing it.

Throughout the history of iron production developed and improved.And the use of this metal today in certain industries can not be replaced, so it is important cutting and drilling of cast iron.Due to the high carbon content, and different ways to apply a special tool for cutting.

As a rule, in a domestic environment, we can recommend the use of drills with pobeditovymi nozzles (for example, BK8 ).This drill bit for cast iron should be used at low speeds, keeping the verticality of efforts and fulfilling part of the cooling of the cutting nozzle, preventing overheating and blackening.

Cutting iron - manufacturing need

Industrially, there are many methods and equipment that solves the problem of how to cut iron.So in the process of production of iron castings it is necessary to cut.In this case, the widely used technique of using thermal cutting methods.As everyone knows, such are arc, electric contact, plasma, air-arc, and others.

In the case of arc way the question of what to cut cast iron, does not occur in principle.It will suit the usual widespread or specialized electrodes brands LIM , AHP-2 or ISP-1 .The use of the latter, of course, increases the productivity of work.

Application arc ways experts recommend not because of their low efficiency and quality.Instead, they recommend the air-arc ways to more efficiency, productivity and quality.

Drilling in industrial scale

in industrial environments with the need to solve the problem, how to drill iron, the relevant machines with a working tool having a special working surfaces of the sharpening.Always use coolant for a given operating temperature.

addition to the question than to drill iron, necessarily need to ask the question of security in the course of such works.Consideration should be given the possibility of the material being processed in an array of cavities, voids and similar defects.This is often due to the large amount of carbon in the iron and a variety of other components.

Yet these sudden defects lead to the fact that the metal processing, a large amount of fine crumbs and dust.treatment methods depend on the type of cast iron, but there are general rules and safety requirements.

As a consequence, during the execution of the works must be carried out generally accepted protective measures.It is necessary to protect the respiratory system.What is needed, in addition to equipment jobsite ventilated hood, use of personal protective respirator or cotton-gauze "petal".

should also protect the eyes.Safety requirements include the presence of shields, safety glasses with side edges closed.Work should be in a special work clothes, gloves and hats.
