The use of deep hole drilling systems in common machine tools
Deep hole drilling is a complex machining process which requires precision. It involves drilling a hole of a specified depth, while maximizing accuracy and minimizing damaging deformation to the workpiece. In order to carry out this process, deep hole drilling systems have become increasingly important.
The main purpose of deep hole drilling systems is to drill a deep hole, often greater than 8 times the diameter of the hole. The system can be used for a variety of machining processes including thin walled high precision holes and blind holes with a deep aspect ratio. There are many types of deep hole drilling systems, each suitable for a specific operation. These may include gun drilling, honing, line boring, whip stocks and pull-through drills.
One of the most important aspects of deep hole drilling is size accuracy. The system must be accurately calibrated to ensure the deepest possible holes with minimal deviation in size. To achieve this, a variety of methods and techniques are employed, such as the use of special machinery, cutting tools, cooling systems, and other technologies. Many of these techniques can be used in combination to ensure optimal accuracy.
The most common deep hole drilling systems are those used in standard machine tools. These systems are composed of the drill unit, cutting tools, and a spindle. The drill unit provides the cutting force and drive, while the cutting tools create the deep hole. The spindle is used to control the depth of the hole, its speed, and other variables. The most common types of deep hole drilling systems are designed to fit onto – and be mounted in – standard machines.
One of the main benefits of using deep hole drilling systems in common machine tools is their flexibility. Most systems are designed with adjustable or extendable components so that they can be configured to fit a variety of drilling needs. For example, some systems can be adjusted to reach different depths and different diameters. This flexibility makes them suitable for a wide range of operations, from small holes to massive cavities. This versatility makes deep hole drilling systems an ideal choice for many machining operations.
Another important benefit of deep hole drilling systems is their ability to work at faster speeds than conventional drilling tools. This is due to the minimized vibrations of the coolants used in this type of drilling, which reduces the heat generated by the process. This means that the cutting process can be performed more quickly, allowing for increased production rates. Furthermore, the higher cutting speeds can also result in better surface finishes.
Overall, deep hole drilling systems provide increased accuracy, flexibility, and faster speeds than conventional drilling tools. They are an invaluable tool for any machinist and can be used to carry out a wide variety of machining operations. With the right set up and calibration, they can provide superior accuracy that is hard to achieve with any other drilling method.
