The Gap Between Domestic And Foreign Electrical Processing Machine Tools

The gap between domestic and foreign electrical processing machine tools

Domestic machine tools have made significant progress in recent years, but there are still shortcomings in the high-end field.

The core gap is not in the comparison of international levels of basic functions of micro parts processing , but in intelligence and stability.

We need to see clearly the actual gap between domestic and foreign electrical processing machine tools in order to find a breakthrough in the competition.

Forming machine tools break through bottlenecks

The performance of high-end CNC EDM machine tools has been greatly improved.

Models with more than three axes have reached the mid-range level and are approaching the international advanced level.

This breaks the long-term foreign monopoly on the international level of micro parts processing and gives the market new choices.

However, thermal deformation control and dynamic and static stiffness design are still lacking.

Expert systems and network integration technology also need further research.

These details determine the precision and efficiency of the final processing.

Wire cutting technology to be supplemented

Unidirectional wire cutting machines have made progress in automatic wire threading.

There have also been major breakthroughs in filament cutting and intelligent technology.

These advancements improve machining accuracy and ease of operation.

However, filament processing efficiency and surface quality are still insufficient.

Automatic electrode wire exchange and network technology are still blank in the country.

To catch up with the international advanced level, we still need to overcome these key problems.

Leading in micro hole processing

Multi-axis CNC micro-hole EDM machine tools account for 90% of the market.

Seven-axis high-speed machine tools developed for aerospace meet demanding requirements.

Its number of axes, hole diameter accuracy and depth-to-diameter ratio reach international standards.

There is still a gap in multi-circuit processing and automatic electrode replacement technology.

The online detection and correction capabilities of complex profiles need to be improved urgently.

This is the only way to go from adequate to perfect.

Analysis of key weaknesses

Thermal stability of machine tools is a hidden killer that affects accuracy.

The structure needs to be optimized during design to resist the effects of temperature changes.

This requires long-term data accumulation and material process improvement.

Intelligence is the core competitiveness of the future.

Automatic loading and unloading and online inspection can significantly reduce labor costs.

System integration capabilities determine the overall operating efficiency of machine tools.

Future direction of efforts

Focus on automatic switching and online detection technology.

Establish a complete expert system to improve operational intelligence.

Strengthen network functions to achieve remote monitoring and maintenance.

Promote the research and development of filament cutting and efficient processing technology.

Filling the domestic technology gaps such as automatic electrode exchange.

Narrow the gap with the top international levels through continuous innovation.

Domestic machine tools are gradually shifting from following to running alongside or even leading the way.

It has become globally competitive in niche areas such as micropores.

The improvement in overall strength will drive the upgrading of the entire manufacturing industry.

Only by facing up to the lack of international comparison of tiny parts processing can we gain a foothold in the fierce competition.

Increasing investment in R&D is key and requires close cooperation between industry, academia and research institutes.

It is expected that China's electrical machining technology will soon reach the world's leading level.
