In the 21st century, humanity officially entered the third industrial revolution era. As an important member of modern advanced manufacturing, the machine tool manufacturing industry is also advancing with the times and undergoing rapid changes.

The intersection of energy and communication broke out in the industrial revolution

Following the first industrial revolution in which the steam engine was born and the release of cheap newspapers, and the invention of the telephone and telegraph and the second industrial revolution that triggered the convergence of the power industry, the intersection of Internet computer communication technology and new energy triggered the third industry. revolution. This revolution began in the early 21st century and was first triggered by Germany. It is expected that there will be a reserve period of 25-35 years from now on, and a new round of industrial revolution will continue to flourish.

It is not difficult to find that a large amount of resources are consumed; oil exploitation cannot keep up with the needs of developing countries such as China and India; air pollution caused by exhaust gas and soot emissions; water pollution of rivers, lakes and seas caused by discharge of waste water and harmful substances; The urbanization of moderation, the destruction of ecological environment caused by factors such as farmland occupation and deforestation; and the rising labor costs are the reasons for the third industrial revolution.

The impact of the third industrial revolution on machine tool manufacturing technology

Affected by the third industrial revolution, machine tool manufacturing technology has focused on energy conservation, environmental protection, green and other aspects of research and development, and high efficiency, high speed, high precision, etc. are always the goal pursued by the machine tool industry. The collection of these essences is a prelude to the machine revolution. We may wish to focus on these results.

Structural innovation of machine tools

At the end of the last century, G&L of the United States debuted the prototype of the parallel machine tool at the Chicago International Machine Tool Show. It is a six-legged measurement platform, and the machine tool has evolved from a traditional C-type drive chain structure to a parallel motion.

The so-called parallel machine tool is based on the spatial parallel mechanism, replacing some hardware with numerical control software, replacing some mechanical devices with electronic devices and components, and quickly changing the relative position of the tool and the workpiece by changing the length of the truss bar and the position of the moving fulcrum. The position changes, thus breaking the tandem kinematics principle of the traditional machine tool based on the Cartesian coordinate system.

Parallel machine tools are developing in the direction of series and parallel due to their weak rigidity and other factors. China's Tsinghua University, Haliang, Changzheng machine tools and other units in this area of ​​research and development in the international leading position.

Inverted vertical vehicle invention

Inverted vertical vehicles invented by EMAG in Germany are particularly suitable for high-volume processing of lightweight rotary parts. Immediately, novel models such as inverted machining centers, inverted composite machining centers and inverted welding machines came into being.
