Deep drilling service
Deep drilling is a specialized and vital process in various industries, especially in the production of parts with high precision and low tolerance. This process creates holes with great depth and high length-to-diameter ratio in various materials. In the following, we will examine the types of deep drilling methods, their applications and the factors influencing the selection of the appropriate method.
A variety of deep drilling methods
Drilling with deep lathe machines: This method is used to create deep holes in large and heavy parts. Deep lathe machines have high precision and the ability to create holes of various diameters and depths. Drilling with gandrills: Gandrils are special tools that They are used to create high quality holes and smooth inner surface. This method is very suitable for drilling hard and resistant materials such as alloy steels.
BTA drilling: This method uses a multi-edge drill. It removes chips through the center of the drill bit. BTA drilling is used to create holes with high precision and smooth internal surface in various materials. EDM drilling: Electric is used to make holes. EDM drilling is suitable for creating holes with complex shapes and in materials that cannot be drilled with traditional methods.
Deep drilling applications
Among the most important applications of deep drilling, we can mention the production of combustion engine parts, aerospace parts, industrial molds, medical equipment, oil and gas industries, as well as in the manufacture of high-precision electronic parts. In the automotive industry, deep boring is used to create lubrication channels, cooling holes, and bolt-through holes in the cylinder block, cylinder head, and other engine parts. In the aerospace industry, this process is used to make turbine components, engine nozzles, and other parts with very precise tolerances. Also, in the production of industrial molds, deep drilling is used to create cooling channels in the molds and create complex holes in the mold parts.
Factors Affecting the Selection of Deep Drilling Method
Choosing the right method of deep drilling is a key factor in achieving the desired quality and precision in the production of parts. There are several factors involved in this choice that must be carefully considered. Among these factors, we can mention the material of the workpiece, the dimensions of the desired hole, the allowed tolerances, the quality of the internal and external surface of the hole, the production volume, the production cost and the equipment available in the workshop. The material of the workpiece has a direct effect on the choice of tools and drilling method. Harder and more resistant materials require more powerful drilling methods such as BTA, while for softer materials simpler methods such as twist drills may be sufficient. Also, the dimensions of the hole and the ratio of its length to its diameter will determine the type of device and tool used.
For holes with great depth and high length-to-diameter ratio, methods such as Gandril and BTA are more suitable. In addition, the allowed tolerances and desired surface quality also affect the choice of method. To achieve very precise tolerances and a smooth surface, methods such as EDM and gandril drilling are preferred. Finally, production volume and production costs also play an important role in the final decision. For mass production, methods that have high speed and accuracy and reduce production costs are chosen.
