Deep hole drilling is a process of drilling holes with a depth-to-diameter ratio greater than 10:1. It is commonly used in industries such as defense, firearm, die and mold, aerospace, medical, and automotive to produce high-quality, accurate holes in various materials.
The benefits of deep hole drilling include improved accuracy, surface finish, reduced cycle time & cost, and increased productivity. Deep hole drilling can also improve the strength and durability of materials.
Deep hole drilling is a process that can be applied to a wide range of materials, such as metals, plastics, composites, and ceramics.
There are several types of deep hole drilling methods, including gun drilling, BTA drilling, counter boring, Ejector drilling, trepanning, and skiving and roller burnishing.
Gun drilling is a deep hole drilling method that uses a long, thin drill bit with a single cutting edge. It is a highly accurate and efficient method that produces holes with excellent surface finishes. Gun drilling is different from other deep hole drilling methods because it uses a single cutting edge and requires high-pressure coolant.
Deep hole drilling is commonly used in applications such as automotive shafts, mold plates, thermowells, fuel injectors, hydraulic cylinders, gun barrels, aerospace components, and medical instruments.
The challenges associated with deep hole drilling include controlling chip formation, maintaining coolant pressure and flow, minimizing tool deflection, and managing heat buildup.
The factors to consider when selecting a deep hole drilling tool or machine include the material being drilled, the hole size and depth, the required tolerances, the production volume and rate, and the available coolant and filtration systems. Other factors to consider include the cost of the equipment and the availability of technical support and maintenance services.
