Drilling Machining Technology
Drilling machining technology is the process of cutting holes into a material using a drilling machine. This type of machining technology is used in a variety of industries, including automotive, aerospace, electronics, and medical. Drilling machines can be either computer numeric control (CNC) operated or manually operated. Drilling machines are used to create holes with a diameter ranging from very small to very large.
Drilling is a fast, accurate and relatively inexpensive process for cutting holes in a variety of shapes and sizes. It is an advantageous machining process used for a broad range of applications. Drilling machines require very little setup time and are easily adjusted for a variety of holes and depths. The cost of the process is reduced since only one tool is used for all holes, reducing the overall machining time.
The most common type of drilling is done with a twist drill bit. The twist drill bit is a two fluted cutting tool with a center tip. These drill bits are available in a variety of materials such as high speed steel, cobalt alloy and carbide. The drill bit is mounted in the spindle of the machine, which contains a rotating shaft. As the drill bit rotates, the cutting edges on the flutes cut material away and the hole forms.
Drilling machines are available in a wide range of sizes and types. There are vertical, horizontal and radial drilling machines all of which can be used for a variety of materials. Most drilling machines are equipped with digital readouts that allow for accurate measurement of the size and depth of the hole. Many CNC drilling machines are also equipped with a programmable drill system that can create multiple holes based on commands programmed by a user.
In drilling, coolant or cutting fluid is often used to improve chip evacuation, lubricate the cutting edge, and reduce the risk of internal build up of heat or pressure. The coolant is generally delivered through a nozzle or nozzle-in-spindle on the drilling machine. It is also important to properly maintain and lubricate the drill bit regularly to ensure long lasting operation.
The drilling process can involve a number of variables such as feed rate and speed, spindle speed and drill size. Adjusting these variables allows for different results, and can be used to create a desired hole size and shape. The most common way to adjust the variables is through the use of a digital readout, which can be programmed to match a specific hole size and shape.
Drilling machining technology is a process that is used in many different industries due to its speed and accuracy. With the increased use of CNC technology, precision drilling is becoming more and more common. Additionally, companies are increasingly taking advantage of improved coolant and lubrication systems to improve drill life and chip evacuation. By following the proper maintenance procedures, drill bits can last far longer than expected, boosting productivity and efficiency in the shop.
