The 13th China Aviation Propulsion Technology Forum 2025

When the roar of the engine cuts through the sky,

Behind it are billions of precise operations.

In this pursuit of a special journey,

Every precision of one thousandth of a millimeter,

It all determines the safety and boundaries of flight.

On September 11-12, 2025, an industry event on the future of aviation and the 13th China Aviation Propulsion Technology Forum 2025 came to a successful conclusion in Xi'an during the golden autumn season.

　　
At this forum where industry elites gather and intelligent sparks collide, United Grinding China, as a deep participant in the field of precision grinding, comprehensively demonstrated high-precision solutions in the machining of aircraft engine blades and aviation precision components. It had productive exchanges with numerous industry experts and partners, witnessing the glory and future of China's aviation propulsion technology together.

　　
At the forum, United Grinding China deeply explained to its customers how high-precision grinding technology can inject strong power into the aviation industry by focusing on two key areas: flat and forming grinding, and internal and external cylindrical grinding.

1、 Flat and Forming Grinding:

The Efficient and Precise Machining Method for Aircraft Engine Blades

The blades, discs, and other components of aircraft engines work in harsh environments and have complex profiles, requiring high machining accuracy and consistency. The joint grinding of M Ä GERLE and BLOHM brands, with their profound accumulation in the field of flat and profile grinding, provides high-precision machining solutions for these "crown jewels".

Taking the M Ä GERLE MFP 51 grinding center as an example:

Its design is compact and suitable for multi axis linkage grinding processing. Equipped with a gantry style 68 station integrated grinding wheel replacement device, it can effectively process multiple different workpieces without any intervention of tools, and can complete all grinding processes and measurements in one clamping.

The high-performance spindle can achieve a speed of up to 12000 revolutions per minute, and the top mounted dresser is integrated into the spindle box, which can shorten the machining time. Compact fixtures can achieve efficient grinding processing, and continuous dressing of grinding wheels can achieve efficient and higher material removal rates. Optional grinding wheel and tool recognition system, as well as nozzle replacement system, to achieve optimal grinding results.

　　
In addition, the BLOHM PLANOMAT XT grinder can meet your production needs with flexible technology, providing the best production support for industries such as tooling, turbine components, etc. that require high precision, flexibility, and stability.

2、 Internal and external cylindrical grinding:

Precision assurance of aviation precision parts

In the aviation field, from precision shafts of servo mechanisms, valve core sleeves of hydraulic systems, to various high-precision shaft parts, the machining accuracy and stability requirements for inner and outer circles, conical surfaces, and complex contours are very strict. The STUDER brand high-precision inner and outer circle series grinding machines under the joint grinding group are the sharp tools for machining such parts.

Taking STUDER KC33 as an example:

The new KC33 has two specifications for the top distance: 650mm and 1000mm. The corresponding top distance specifications have load-bearing capacities of 80kg and 120kg, respectively. The bed is made of STUDER's classic artificial granite material, which has excellent shock absorption, excellent thermal stability, and strong structural rigidity, effectively improving the quality of grinding processing.

The STUDER guide rail is directly formed on the artificial granite bed, making it easy to achieve micro feed with X-axis and Z-axis servo drive. The grinder can be equipped with a fixed or automatic turret type grinding wheel holder, which can achieve automatic rotation in the range of -15 ° to+195 ° and 1 ° indexing.

KC33 provides assurance for the rigorous machining requirements of high-precision aviation components such as gear shafts, sleeves, and servo valve cores.

　　
In addition, the STUDER S33 CNC universal internal and external cylindrical grinder can be equipped with a universal grinding wheel head frame with up to 2 external grinding spindles and 1 internal grinding spindle, which can achieve grinding tasks from small workpieces to large workpieces, from single piece production to batch production.

As an expert in the field of inner hole, arc and spherical grinding, S131R is equipped with a fully automatic B-axis, X-axis and Z-axis linear motors with direct drive devices, which have high precision and fast interpolation response speed. The grinder can be equipped with a grinding wheel head frame with up to 4 grinding spindles, which is flexible and can meet diverse processing needs such as circular arcs and conical surfaces.

STUDER grinding machines provide reliable assurance for the processing of complex aviation parts due to their high precision, stability, and quality.

Promote new aviation power, intelligently create efficient and sustainable solutions

Chasing dreams in the sky, walking incessantly. At this forum, United Grinding China not only presents high-precision grinding technology, but also a precision art that helps major countries' heavy weapons fight in the long sky.
