Drilling machine is one of the highly researched and developed machine tool models. Due to its multi-task processing and multi-spindle structure design, it can process forming and boring related tasks in one stop. Drilling machines have evolved from milling machine designs. Since then, diverse machining centers have been widely used in various industries for professional and precision machining. With the introduction of multi-spindle technology on the market, multi-spindle drilling machines have been highly welcomed in many ways.
The name "drilling machine" can be used to describe a variety of CNC drilling machines, including several key accessories designed and assembled with the machine body, such as tool magazine, ATC, CMM, multi-axis working table with different guides, and other auxiliary accessories. These accessories are used to improve the accuracy and precision of drilling. Milling machines and drilling machines are types of machine tool whose machining process advances a rotating tool into one or more work pieces to remove material, and the entire process can be controlled by the CNC system or manually operated.
Although today's milling and drilling operations are mainly controlled by CNC program, for some reasons, such as customized production and processing, the need for manual operation still exists. The milling and drilling processes performed on a single machine can meet a variety of machining requirements, and this capability is based on different tracks installed on the axes, allowing the machining tool to move around the work piece.
In fact, the number of axes depends on customer needs. There is no absolute optimal number, only the best solution based on user needs.
Milling and drilling method covers a wide variety of operations, ranging from single tiny parts to heavy duty milling tasks. At the same time, it is similar to turning in some ways. Milling and drilling are the most widely used machining methods, which provide precise tolerances under strict standards. The research and development of milling methods are highly praised in the industry because of their effectiveness for machining work pieces with complex contours and depths. This is difficult to achieve with traditional processing methods.
From the application of milling and drilling, many processing methods are extended. One of the most popular and widely used methods is the machining center. The machining center is a highly developed machine tool that can handle multiple types of milling, drilling, and even boring tasks simultaneously.
Initially, due to increasing demand from aerospace and automotive industries in United States, machining centers evolved from milling machines in the 1960s, and this trend has since expanded to other areas of the world. The machining center is widely used in various industries and has made extensive contributions to the industry.
Milling is the process of removing material by pushing a rotating tool into one or more work pieces. This processing method can be done in different directions. Milling can involve a wide variety of operations, ranging from single tiny parts to heavy duty milling tasks. Similar to turning, milling is one of the most commonly used machining methods.
Speaking of drilling at the beginning, this is the process of drilling holes in a work piece that has already been cast or cut, such as drilling holes for ventilation holes, or rough drilling on engine cylinders. Through subsequent boring, higher hole diameter accuracy can be obtained and can also be used to create tapered holes.
In the machining details, the drilling can be regarded as the internal diameter machining in turning. The drilling bar can be supported at both ends or at one end.
The research and development of milling and drilling methods are welcomed in the industry because it can process work pieces with complex contours and diameters on a single machine, which is difficult to achieve with traditional machine tools. With this expectation, the concept of the machining center gradually be realized in the industry in the near future.
