Start Discussing Your Project

Challenge

Achieving precise geometric tolerances for high-speed automated assembly of bearing housings for industrial robots.

The Solution

High-precision CNC machining bearing seats with advanced metrology and CMM verification

The Result

Eliminated vibration issues, extended bearing life, and shortened development cycle by 3 months

The CNC Machining Challenge

A German company faced a daunting challenge: developing a new generation of high-speed industrial automated assembly robots capable of operating with unprecedented precision and minimal downtime.

A critical bottleneck quickly emerged in the bearing assembly for the main drive shaft. The existing “industrial bearing housing,” sourced from a long-standing supplier, could not meet the stringent geometric tolerances required for the higher speeds and longer operating cycles of the new design.

Specifically, achieving the necessary concentricity between the bearing bore and mounting surface, as well as perpendicularity to the axis, proved difficult. This resulted in unacceptable vibration levels, premature bearing failure, and ultimately, a costly disruption to the development program.

Critical Tolerance Requirements

Concentricity: ≤0.002mm between bearing bore and mounting faces
Perpendicularity: ≤0.0015mm to shaft axis
Surface finish: Ra 0.8μm maximum
Dimensional accuracy: ±0.005mm

Our Solutions

We understand that the success of a new generation of robotic platforms hinges on resolving critical precision challenges. After extensive research, the client selected VMT for our comprehensive technical documentation and years of experience in high-precision CNC machining. During the initial consultation, our team fully understood the client’s challenges and proposed practical solutions. Through multi-axis CNC machining and advanced testing methods (including three-dimensional CMM inspection, concentricity, parallelism, and other key indicators), we ensure that parts meet stringent tolerances.

VMT boasts 100 3-, 4-, and 5-axis CNC machines and a standardized production workshop, achieving machining accuracies of ±0.005mm and a high-quality surface finish. We customized the client’s process, achieving micron-level accuracy and significantly improving surface quality, thereby reducing friction and extending bearing life. Upon receipt of our CNC precision industrial bearing housing, the client’s testing results fully met their requirements, completely resolving their long-standing vibration issues during the robot trial production.

Summary:

Following the initial consultation, our team developed a tailored process to meet their exact needs:

Multi-axis CNC machining to ensure uniform material removal and consistent tolerances
In-process inspection checkpoints at every production stage
Post-machining CMM verification for 100% of parts
Specialized surface finishing to minimize friction and extend bearing life

5-axis CNC Machining

Advanced machining technology enabling precise control and complex geometries.

CMM Verification

Coordinate Measuring Machine ensures all tolerances are met with micron precision.

The Results

Our precision CNC machining bearing seats transformed their robotic platform development, delivering exceptional performance improvements and significant time savings.
After integrating these new bearing housings into their prototype robot, persistent vibration issues were immediately resolved. Their drive shaft now maintains exceptional stability and smoothness, even under maximum loads and speeds. This not only enables them to validate new robot designs but also significantly reduces maintenance costs and significantly extends the machine’s lifespan.
