Germany

Shaping industrial Benchmarks together with "Hidden Champions"

Client: A century-old family business in Germany (an "invisible champion" in the industrial field)

Industry: High-end hydraulic and pneumatic systems

Equipment used: Fully automatic deep hole processing production line (integrated gun drilling and honing)

Background and Challenges

This German enterprise, renowned for its rigor and quality, is seeking deep hole processing partners for its world-class hydraulic valve blocks. Their challenge lies in the fact that the workpiece material is high-hardness special stainless steel, the deep hole network is intricate, and the burr control at the cross holes and the consistency of the inner wall require extremely high standards. Meanwhile, they pursue the automation and digitalization of production, hoping to achieve unmanned production in a "dark factory" style.

Solution

We do not merely sell single machines; instead, we have customized a fully automatic intelligent production line for them that integrates robot loading and unloading, online measurement, deep hole gun drilling and deep hole honing processes.

Integrated "drilling - honing - cleaning" : All deep hole drilling, honing and high-pressure cleaning of the workpiece are completed in one clamping, ensuring uniform reference and ultra-high precision.

Intelligent technology for difficult-to-machine materials: For high-hardness materials, the tool geometry and cutting parameters of the gun drill have been optimized, and combined with the honing process, the problems of internal wall stress concentration and surface strengthening have been perfectly solved.

Industry 4.0 interface: The production line is equipped with a data acquisition system that can monitor equipment status, tool life and processing parameters in real time, and seamlessly integrate with the customer's MES system.

Achievements and Values

Peak quality: The inner hole quality of the processed valve body far exceeds the DIN/ISO standards, achieving nearly zero burrs on the cross holes and inner wall defects.

Efficiency and cost optimization: Fully unmanned operation throughout the line has reduced manual intervention by 90%, and tool life management has optimized consumable costs by 30%.

Deep trust: With our relentless pursuit of quality and intelligent solutions, we have earned the respect of this "German master" and established a long-term strategic cooperative relationship.
