Scraping of Contact Surfaces Between Components

1. Scraping improves surface flatness, contact quality and contact density, and hardens the surface for better wear resistance.2. Surface quality is evaluated by contact points per unit area, with a standard of 12-16 points/25×25mm.

2

Laser Interferometer Inspection

Analyzes dynamic characteristics of ball screws, response of drive systems and dynamic performance of guide rails with high precision and efficiency, providing data for machine error correction.

3

Ball Screw Transmission Assembly

Parallelism between ball screw and guide rail is adjusted by grinding screw nut seats, with a control requirement of 0.01mm/300mm.

4

Spindle Assembly

Assembled in a constant-temperature workshop to ensure precision and quality. Spindles are tested for abnormal noise and temperature rise before installation.

5

Gear Precision Inspection by Gear Measuring Instrument

Measures and evaluates gear precision indexes (profile deviation, helix deviation, pitch deviation, radial runout, etc.) in accordance with GB/T10095-2001 (equivalent to ISO1328:1997).
