Introduction
Deep hole drilling system is a type of technology used in the field of engineering in order to create precision deep holes in materials. It usually consists of a hole drilling machine, drill bit, and a chucks that can be used to secure the bit to the material. This technology has been around for decades and is used in many industries to generate precise holes in a variety of materials, such as steel, aluminum, fiberglass and plastic. The use of deep hole drilling system is becoming increasingly popular among companies as it offers immense benefits in terms of accuracy, speed and cost.
Deep hole drilling systems are often used to modify common machine tools for deep hole drilling applications. This modification involves replacing the existing drill bit and chucks to those specifically designed for deep hole drilling. It’s important to note, however, that the modification is much more complex than simply replacing the bits and chucks, as modifications to the machine require a detailed review of the machine’s parts and components and an understanding of how the machine will function with the added components.
There are a number of ways that deep hole drilling systems can be used to modify existing machine tools for deep hole drilling applications. This section will explore seven common methods:
1. Adding chuck adapters
Chuck adapters are components that are designed specifically to help connect the deep hole drill bit to the spindle of the machine tool. This allows the spindle to rotate the drill bit, enabling the machine to reach deeper into the material being drilled. The chuck adapter must be designed in a way that allows it to fit the particular spindle being used, and the appropriate chuck must be chosen in order to facilitate the drilling process.
2. Adding a collet adapter
Collet adapters allow the deep hole drilling system to be used with a wide range of drill bits. The collet adapter itself is a small piece of material, such as brass or bronze, which fits over the drill bit, allowing it to be secured to the spindle. It is important to choose the correct size collet adapter for the drill bit being used, as this will ensure that the drill bit is properly secured.
3. Adding a coolant system
An effective cooling system is essential for deep hole drilling as it helps to prevent the drill bit from overheating and can improve the accuracy of the drilling process. A typical coolant system includes a coolant tank and nozzle and a tube assembly which helps direct the coolant to the drill bit. This type of system should be added to the machine when modifying it for deep hole drilling applications.
4. Adding a guide tube
A guide tube is a tube which is attached to the top of the drill bit and helps keep it in a straight line while drilling. Guide tubes are particularly useful when drilling deep holes in steel, as they help to keep the drill bit in the same place and guide it in the correct direction. Guide tubes should therefore be considered when modifying a machine tool for deep hole drilling.
5. Adding a centering device
In order to ensure that the drill bit is kept in the center of the workpiece, a centering device can be implemented. A centering device fits over the drill bit and allows for precise alignment of the drill bit in relation to the workpiece. This is especially important for precision deep hole drilling, as it helps to minimize any movement of the drill bit which may result in inaccuracies.
6. Adding an adjustable feature
An adjustable feature can be added to a machine tool in order to allow for quick changes to the drilling parameters such as the speed, feed rate, and weight of the drill bit. This is extremely useful when attempting to optimize the process and can help to ensure that the deep hole drilling goes as smoothly as possible.
7. Adding depth control
Depth control is an important feature when drilling deep holes, as it helps to ensure that the hole is drilled to the correct depth. This can be achieved by manually adjusting the drill parameters or by installing an automated control system. The automated control system will allow for real-time control of the drilling process, as well as providing data on the progress of the drilling.
Conclusion
Deep hole drilling systems can be used to modify existing machine tools for a variety of deep hole drilling applications. This can be done by adding components such as chuck adapters, collet adapters, coolant systems, guide tubes, centering devices, adjustable features, and depth control systems. All of these components are essential when attempting to achieve precision deep hole drilling, and it is important to understand how they all work together when modifying a machine tool for deep hole drilling applications.
