Deep Hole Drilling
Deep Hole Drilling is a form of machining that entails drilling a deep, incredibly straight and uniform hole into a hard material in order to create a smooth finish. This type of drilling is a common method used to create bores, counter-boring, reaming, and more. As there are no other machining processes that are able to perform such a deep and accurate drilling, it has become increasingly popular amongst industrial machinists.
Deep hole drilling is a drilling process that is performed by using a drill bit, normally one that is exceptionally long. Longer drill bits are typically used to penetrate deeper and thicker materials, as they tend to limit the feed rate and the drilling speed. Some applications of deep hole drilling require the use of carbide tipped and carbide rods, which are incredibly sturdy and provide greater accuracy and longer life. Depending on the material being drilled, most deep hole drilling operations will require a dedicated device that can sustain the pressure applied by the drill and drill bit.
Most deep hole drilling is done on lathes, milling machines, and CNC machines. However, dedicated deep hole drilling machines also exist, as they produce a more accurate hole with a higher quality finish. Dedicated deep hole drilling machines typically support systems of two spindles in order to drill two holes at the same time. This allows for a faster, more accurate drilling process while also increasing productivity. Most modern deep hole drilling machines also employ a tailstock in order to handle the long drill bit, as well as multiple axes and CNC controllers that control the speed of drilling and feed rate.
When it comes to deep hole drilling, there are many benefits that it can offer over other machining processes. For one, it produces incredibly accurate parts as the drill never pulsates nor does it wander laterally. Through the use of advanced programming, deep hole drilling can also produce difficult shapes with unique end cuts. By controlling the speed of rotation and feed rate, deep hole drilling is capable of producing smoother finishes and more accurate drilling results.
Finally, there are a variety of advantages that come with using dedicated deep hole drilling machines. There is a greater range of motion. Also, different inserts can be applied to the drill bit, increasing cutting quality and performance. With these machines, advanced feeds and speeds can be accurately tailored to the material being drilled providing a much shorter and accurate cycle time. There is also less tooling change-over time and increased tool life due to the use of CNC controlled speed.
In conclusion, deep hole drilling is a form of machining that entails drilling a deep, incredibly straight and uniform hole into a hard material in order to create a smooth finish. This type of drilling is a common method used to create bores, counter-boring, reaming, and more. It can be performed on lathes, milling machines, and CNC machines or with the use of deep hole drilling machines. Deep hole drilling offers a high level of accuracy and can be used to produce incredibly intricate designs. With the use of deep hole drilling machines, there are also many more benefits such as greater range of motion, advanced feeds and speeds, and less tooling change-over time. Overall, deep hole drilling is an efficient and cost effective way of drilling and shaping hard materials.
