Part Loading in Machining and CNC Machining Centers
PM Manipulators Make Handling Heavy Metal Parts in Machining Lines Fast, Safe, and Ergonomic with Pneumatic Systems
Ergonomics and Precision Needs in Machining
In CNC machining operations, the continuous loading and unloading of parts is critical for both operator fatigue and production continuity.
Manual handling can lead to serious issues such as back and shoulder injuries, dropped parts, and lost production time.
PM Industrial Manipulators address these challenges with 100% pneumatic solutions, reducing operator strain, increasing line efficiency, and enhancing workplace safety.
CNC Part Handling Technology with PM Manipulators
The pneumatic balancing system makes heavy parts feel “weightless” for the operator.
Operators can lift, rotate 90°, and precisely place heavy metal parts into CNC machines single-handedly.
Each model ensures surface protection, vibration-free motion, and high control precision, keeping parts undamaged during positioning.
