Gear Grinidng Machine with online measuring system
Introduction:
This gear grinding machine incorporates five servo axes and two direct-drive electric spindles, with all five axes under full closed-loop control for ultra-precise motion synchronization. Leveraging the profile grinding principle, it achieves high-accuracy gear machining by directly driving both the grinding wheel and workpiece via torque motors, eliminating transmission chain errors and enabling efficient, high-precision batch production of gears.
Key Technical Features:
-
Closed-Loop Servo System
- The workpiece axis employs a direct-drive closed-loop servo mechanism, ensuring positional accuracy within microns.
- The tailstock integrates a hydraulic-manual compound mechanism for rapid clamping and fine-tuning, while both headstock and tailstock remain stationary during operation, supported by precision adjustment mechanisms to minimize thermal deformation.
-
Grinding Capability
- Capable of machining high-precision gears in mass production, including special geometries (e.g., cycloidal gears, splines) with diameters up to φ400 mm.
- Suited for critical industries such as automotive powertrains, aerospace gearboxes, and precision machine tool drives, where dimensional accuracy (up to ISO Grade 5-6 ) and surface finish (Ra ≤ 0.8 μm) are paramount.
-
Advanced Software & Measurement
- Equipped with specialized CNC software supporting grinding of complex tooth profiles (e.g., cycloidal, involute) and splines, with built-in functions for automatic tooth profile and lead correction.
- Features an integrated contact-type gear alignment and on-machine measurement system, enabling real-time accuracy verification (e.g., pitch error, profile deviation) and generating detailed inspection reports.
-
Process Stability
- The coolant system incorporates dual-stage magnetic and paper filtration to maintain abrasive particle cleanliness, coupled with constant-temperature control to mitigate thermal expansion effects during prolonged operation.
-
User Interface & Operation
- The HMI features a menu-driven dedicated interface for intuitive programming of grinding parameters (e.g., wheel speed, feed rate, dressing cycles), reducing operator training time and enhancing production efficiency.
