DEEP DRILLING

The drilling process is widely used in the manufacturing industry, responsible for approximately 30% of all machining operations. Despite approximately 60% of the drilling applications in the mechanical industry being of short drills, with depth up to 2.5 times the diameter of the tool, many operations require depths greater than 5-fold the diameter.

While normal techniques produce holes with depths rarely greater than 5-fold the diameter, in deep hole drilling, the range can reach up to 150-fold the diameter of the hole.

This type of operation usually requires the use of special tools and equipment. Deep drilling has a greater complexity level than the conventional one due to the critical machining conditions in which it is developed. Such conditions involve the difficulty in forming and evacuating chips, the length in contrast to the size of the tool, the quality of the surface, the geometric tolerances, and the format of the hole.

Key characteristics of deep drilling:

• High capacity of advancement and depth;
• Drilling tolerance between IT 6 - IT 9;
• Good drilling geometry;
• Good superficial finishing;
• Small deviation.

In order to meet the demands of the market, SAMOT uses different equipment models to perform the deep drilling processes, using several tools (gun drill bits and twist drill bits, for example).

Deep drilling is yet another key feature at SAMOT to meet the market needs in several segments, always focusing on the result sought by the client.
