SWM1507A CNC External Thread Grinder-CNC machine tool manufacturing experts - providing customized solutions to a variety of customers

SWM1507A CNC External Thread Grinder is a high-precision CNC thread grinding equipment for external thread finishing. With mineral casting rigid bed and professional CNC control system, it realizes stable, high-precision batch manufacturing of various complex threaded shafts.

Machine Body Structure & Accuracy Guarantee

Integrated machine base and bed with mineral casting construction, effectively reduces equipment vibration during operation and delivers ultra-high dimensional stability and machining precision for thread workpieces.

Wide Machining Scope of External Threads

Specially developed for external thread grinding on multiple precision components, covering ball screws, worm shafts, rolling dies, and automotive steering core parts, meeting diverse industrial thread processing demands.

Key Thread Machining Technical Parameters

Maximum grinding helix angle: ±30°
Supports multi-start thread grinding
Minimum controllable thread pitch: 0.3mmHigh flexibility for large lead angle and special screw thread production.

Intelligent Compensation Technology

Equipped with automatic grinding wheel wear compensation function, it automatically offsets wheel abrasion in continuous mass production, avoids frequent manual correction, and keeps uniform thread tolerance and surface roughness in long-term processing.
