Deep hole drilling is a machining technique used to efficiently create holes with a diameter of 5 mm or more in a variety of materials. It is also referred to as gun drilling and is an important part of precision machining. Unlike conventional drilling techniques with relatively slow feed rates and high thrust, deep hole drilling uses high-speed feed with low thrust and advanced coolant techniques. The result is deeper, accuracy, and smoother holes that can be produced at higher rates.
Deep hole drilling can be used for a variety of materials, including stainless steel, brass, aluminum, and carbon steel. The tools used for deep hole drilling often use special drill bits with various combinations of diamond or carbide drills that are designed to effectively cut through hard materials. During the drilling process, the hole is lubricated with an advanced coolant to ensure smooth and uninterrupted cutting, as well as minimize wear and tear on the drill bit and material.
One of the advantages of deep hole drilling is that it can be used to create a variety of hole shapes and sizes. This technique can be used to create both blind and through-holes with varying depths and diameters. It can also be used to create a consistent depth while drilling multiple holes of the same size. Additionally, deep hole drilling produces holes with a high degree of accuracy, which makes it ideal for applications where a high level of precision is required.
Deep hole drilling also offers cost benefits, as it can produce holes with a short lead time and minimal tool wear. This technique is also highly efficient and can reduce waste, as it does not require additional steps for deburring or reworking of the material.
Finally, deep hole drilling can be used in a variety of industries, including aerospace, automotive, electronics, and medical. Because of its accuracy and efficiency, deep hole drilling is a common machining technique for many critical components and assemblies. As such, it is important for shops to be equipped with the right tools, coolant systems, and knowledgeable machinists to ensure high-quality and safe results.
