Deep hole Drilling Machine
As a general term, deep hole drilling machine (also referred to as deep hole drilling machine) is a drilling machinery used to make deep holes in the workpiece. Generally, the deep holes need to be machined into the workpiece. The depth of the hole can reach several times the diameter of the hole. The deep hole drilling machine has the features of high efficiency, large processing depth and high precision. Especially in the aerospace and navigation industry, mechanical manufacturing industry and automotive parts manufacturing industry, the deep hole drilling machine plays a vital role.
Deep hole drilling machine can be divided into two categories: mechanical deep hole drilling machine and non-mechanical deep hole drilling machine according to its driving form. The former is driven by mechanical force and has a wide range of applications. The latter is driven by pressure, vacuum, electrochemical and laser etc., which are applicable to small hole, complex hole and longitudinal hole.
According to the shape of the hole, the deep hole drilling machine can be divided into a variety of types and specifications, such as vertical deep hole drilling machine (sometimes abbreviated as vertical deep hole drilling machine), horizontal deep hole drilling machine, multi-hole deep hole drilling machine and multi-axis deep hole drilling machine etc. The most widely used is the vertical deep hole drilling machine, which mainly contains gun drill, cross deep hole drilling machine and inner hole deep hole drilling machine.
Deep hole drilling technology is in the development stage, and the research on this field is still very active. But with the achievements in the industrial sector, the advantages of the deep hole drilling technology have been continuously improved and its application range has become wider.
1. Application field
Mechanical deep hole drilling machine is mainly used for deep hole processing of hard and brittle materials, such as cast iron, stainless steel, aluminum alloy, titanium alloy and other metal materials. The combination of machining accuracy and productivity has become the basis for increasing the application of deep hole technology.
In addition, with the application of advanced numerical control technology in deep hole drilling, the functions added by deep hole processing have been further developed, such as tapping, rotating, grinding, cutting and drilling. These functions are widely used in the fields of automobile parts, aerospace, aviation, etc., such as the processing of automotive parts, aerospace parts, aviation parts, etc., as well as heat treatment and mold manufacturing.
2. Technical Parameters
Common vertical deep hole drilling machines , its technical parameters mainly contain drilling capacity (meaning maximum depth and diameter of hole machining), table size (meaning maximum vertical and horizontal travel of the tool head spindle), spindle speed, spindle drilling motor power and spindle feed motor power, etc.
Its also necessary to note that for machines with higher technical requirements, additional parameters may need to be considered, such as spindle vibration frequency, spindle boring force, spindle feed force, spindle radial runout, spindle angular runout, spindle torsional stiffness, spindle torque, spindle drilling feed, spindle feed force, spindle bearing diameter and rotation inertia, etc.
3. Development Direction
With the continuous development of the deep hole drilling technology and machinery industry , the development of deep hole drilling technology will also go to the direction of high precision and high efficiency.
(1) High precision: As the precision of deep hole drilling machinery continues to improve, automated machining technology will be equipped with deep hole drilling machinery to reduce manual intervention and manual errors. In addition, for the realization of one-time processing of parts, deep hole machining technology will be applied to reduce the number of subsequent secondary processes and improve the processing quality.
(2) High efficiency: With the development of numerical control technology and the progress of mechanical manufacturing materials and techniques, high-speed and high-efficiency deep hole drilling process can be achieved through high-speed machine tools, special materials and processing techniques.
(3) Automation: With the development of automation technology, the realization of intelligent robots operating measurement and automatic tasks on the machining line will become the main trend. Deep hole drilling processing is the most valuable point of automation in mechanical manufacturing, so deep hole drilling is bound to become one of the processing areas dominated by automation in the future.
In conclusion, deep hole drilling technology will not only provide the necessary precision and accuracy for the manufacture of parts, but also increase the production efficiency. As the development of deep hole drilling technology continues, new ways of processing and new materials will be processed and applied, which will enable the industry to have more optimal processing and manufacturing methods.
