The drilling machine is one of the highly researched and developed machine tool models in the drilling sector together with the drill tools. Due to its multi-tasking function and convenient design, drilling machine can handle various types of boring tasks in one stop with the help of good tools and accessories. The heavy duty drilling machine has greater torque and working capacity, and can drill holes on hard work pieces and thick work pieces with multiple tools and accessories.
In the past, drilling machines evolved from milling machine design in the early 20th century. So the drill tools contain certain mill tools’ features. Since then, diverse machining centers have been widely used in various industries for professional and precision machining, and have made extensive contributions to industrial achievements. Drilling is never old fashioned but will only get more and more popular. So, the study of drilling and tapping tools will boom as well as the accessories, because these are all the accessories.
The term CNC drilling machine or driller can be used to describe various computer numerical controlled drilling machines, including several important accessories and tools designed and assembled with the machine itself, such as tools’ magazine, automatic tools’ changer (ATC), coordinate measuring machine (CMM), multi-axis working tables with different guide movement designs, as well as many other auxiliary accessories for tools. These accessories are used to further improve the accuracy and precision of the drilling or tapping processes. The development of machine tool accessories is professional in Taiwan.
Now, many drilling machines and drillers are not limited to the drilling, but can also be used for milling, which is supported by accessories. This is because market trends now require more use of machine tools, especially rare used machineries such as drilling and boring machines. Machine tools have to be versatile and so does the cutting tools.
Generally, the tapping, milling and drilling processes performed on a single machine can already meet a variety of machining requirements, and its performance depends on the different tracks installed on the axis, so that multiple tools move around the work piece. The number of axis depends on customer needs. There is no absolute optimal number, only the best combination according to user needs. Unlike turning, tapping, milling and drilling cover a wide variety of operations and involve a wide range, from a single tiny part to heavy duty milling tasks. Tools involved are suitable for the specific tapping, milling, and drilling tasks.
It is also similar to turning in some ways. Tapping, milling and drilling are the most widely used machining methods, which provide precise tolerances within rigid standards. The research and development of milling methods and milling tools are highly valued in the industry due to their ability and effectiveness to process work pieces with complex contours and depths, which is difficult to achieve with any traditional machine tools.
With the development of milling and drilling technology, many machining methods have emerged, and one of the most popular and widely used methods is the machining center. The machining centers are highly developed machine tools that can handle milling, drilling and even boring tasks simultaneously with the tools installed for many tasks such as tapping.
Initially, due to increasing demand from aerospace and automotive industries in United States, machining centers evolved from milling machines or other related machine tools in the 1960s. Later, this trend spread and became popular in industrial markets around the world.
All machine tools used to be controlled manually. After the beginning of the era of automation, Numerical control technology began to be used to control machine tools and the cutting tools. The development of this type of machine tools is progressing well in the entire industrial field. After that, the machining center was widely used in various industries.
Milling is the process of removing material by pushing rotating tools into one or more work pieces. This processing method can be done in different directions. In addition to turning, milling also involves a variety of operations, ranging from single tiny parts to heavy and large milling tasks. Similar to turning, milling is one of the most commonly used machining methods. Compared with other methods, it can provide more precise tolerances with the tools’ machining.
Drilling is the process of drilling holes in a work piece that has been cast or cut, such as drilling holes in ventilation holes or rough drilling on engine cylinders. Through the subsequent boring process, higher hole diameter accuracy can be obtained by the tools, and tapered holes with specific specifications can also be formed. From a machining point of view, drilling can be regarded as internal diameter machining during turning. The drilling bar can be supported at both ends or only at one end.
Heavy duty drilling machines with CNC systems can perform a series of tasks and create maximum profits for the production line. Therefore, most manufacturing plants now use this control system to handle the machines and the accessories.
