Why call on a deep drilling subcontractor?

A subcontractor in deep drilling is essential on an industrial site. He has extensive experience in the field to be able to carry out drilling operations. Entrust your drilling work to SMEPI.

Precision deep drilling, a very delicate task

Deep drilling is an operation that requires not only specific know-how, but also high-performance equipment. It is all the more delicate since this operation requires extreme precision. Thus, it should not be entrusted to just anyone. It is necessary to choose a qualified company to undertake such an operation.

In some cases, a deviation, however small, is not tolerable. Precision is essential  for  carry out a drilling in the rules of the art. It should be noted that in fields such as chemistry, petrochemicals or nuclear power, but also in advanced mechanics, the slightest error during drilling risks being fatal, thus leading to injuries and the compromise of the production site.

The power of the machines, as well as the performance, reliability and robustness of the heads, are essential for this operation. The use of specialists such as a subcontractor in deep drilling is then presented as a simple and safe solution to carry out this type of work. They carry out drilling works in accordance with standards.

Note that deep drilling can be done in different ways. However, the best known technique is linear drilling in a rotating part. For this type of drilling, the use of a specific machine is necessary in order to combine the rotation of the tool and the part.

The principle of deep drilling is based on cutting speed and feed. Sometimes it requires a specific technique such as precision deep drilling. The latter consists in carrying out a long drilling without turning over and for that, it requires a particular method and specialized tools. For this purpose, the deep drilling work must be entrusted to a subcontractor.

How can a subcontractor help you in deep drilling work?

Deep drilling is a technique for drilling holes characterized by a high diameter / depth ratio. The frequently used method is to rotate the workpiece and feed the tool in a linear fashion. However, other methods exist such as the rotation of the tool or the simultaneous rotation of the part and the tool.

Whatever solution is chosen, carrying out deep drilling operations requires the skills of professionals in order to obtain quality parts. In this case, it is wise to entrust the performance of these operations to specialists who have the necessary equipment and a qualified team.

By using the services of a deep drilling subcontractor , you benefit from the know-how of qualified and competent professionals.
