Planetary Roller Screw CNC Grinding High Precision Tray Lifting Screw Custom Turning

2025-09-11


Planetary Roller Screw CNC Grinding High Precision Tray Lifting Screw Custom Turning
Product Description

This case demonstrates the CNC machining process of tray lifting screws, utilizing hard turning and wheel grinding to address the challenge of long nut internal thread processing. High-precision grinders (e.g., P1 grade) control micron-level tolerances, ensuring nut tooth profile accuracy and surface finish for planetary roller screws, meeting the frequent start-stop demands of service robots.
