The technology of internal and external cylindrical vertical grinding machines has made another breakthrough, facilitating the upgrading of the precision manufacturing industry

Recently, with the continuous increase in the demand for precision processing in the high-end equipment manufacturing industry, the internal and external cylindrical vertical grinding machine, as a key processing equipment, has ushered in a new round of technological innovation. Many domestic machine tool enterprises have successively launched high-precision and intelligent vertical grinding machine products, providing more efficient solutions for the processing of precision parts in fields such as aerospace, automobiles, and energy.

Technological upgrade: Equal emphasis on high precision and intelligence

The internal and external cylindrical vertical grinding machine is mainly used for processing the inner and outer surfaces of cylindrical and conical workpieces, especially suitable for high-precision grinding of large rotary parts. The new generation of vertical grinding machines, based on the traditional structure, integrates digital control technology and has the following advantages:

Ultra-high precision: With a high-rigidity bed structure and a precision spindle system, the roundness of the processed parts can be within 0.001mm, and the surface roughness Ra≤0.2μm, meeting the strict requirements of key components such as precision bearings and gears.

Intelligent control: Equipped with a numerical control system (such as Siemens, Fanuc, etc.), it supports automatic tool setting, online measurement and error compensation, significantly reducing manual intervention and improving processing consistency.

High efficiency and energy conservation: Optimize the grinding process to reduce energy consumption. At the same time, it is equipped with an automatic loading and unloading system to achieve continuous production.

The market demand is strong, and domestic equipment is emerging

With the rapid development of industries such as new energy vehicles and wind power, the demand for large precision rotary parts has soared. The high-end vertical grinding machines that used to rely on imports are now gradually being replaced by domestic equipment. For instance, the VGM-3000 vertical grinding machine newly launched by XX Machine Tool Group adopts hydrostatic guide rail technology and an intelligent temperature control system. Its processing stability has reached the international advanced level and has been successfully applied to the mass production of core components of a certain aerospace engine.

Opinions of Industry experts

Experts from the China Machine Tool Builders' Association stated: "The technological progress of internal and external cylindrical vertical grinding machines reflects China's independent innovation capabilities in the field of high-end CNC machine tools." In the future, with the integration of 5G and Internet of Things technologies, intelligent grinding machines will further develop towards unmanned and flexible directions.

Looking forward to the future

Under the impetus of the "Made in China 2025" strategy, the trend of intelligence and greenness of internal and external cylindrical vertical grinding machines will become more prominent. Relevant enterprises are increasing their investment in research and development, breaking through key technologies such as ultra-precision grinding and digital twins, and helping China's high-end equipment manufacturing move towards the high end of the global value chain.
