High-Speed Hob Spindle
Spindle speeds up to 2,500 rpm, depending on model, enable efficient high-speed gear machining and improved productivity.
Multi-Axis CNC Synchronization
Five-axis CNC interpolation synchronizes linear and rotary axes during continuous gear cutting, maintaining coordinated tool movement for spur and helical gear machining.
Machining Applications
Xuanman CNC Gear Hobbing Machines are designed for precision machining of gears and shaft-type power-transmission components.
Automotive: Transmission gears, gear shafts, drive shafts and other powertrain components.
Industrial Machinery: Reducer gears, cylindrical gears, motor shafts and other power-transmission components.
Railway: Spline shafts and other precision transmission components for railway applications.
New Energy Vehicles: Gears and shaft components used in EV and hybrid powertrain systems, subject to the required specifications.
Other Applications: Agricultural machinery, pumps and other industrial components requiring CNC gear hobbing.
Automation Solutions
Xuanman can integrate automatic loading and unloading systems according to the workpiece and production requirements. Available solutions include gantry loaders, robotic handling, conveyors, hydraulic workholding and chip-removal systems.
For multi-machine production lines, automation can be evaluated together with machine layout, material flow and production volume.
Customization
Xuanman can customize the machine according to the workpiece drawing and production requirements. Options include:
Workholding: Hydraulic mandrels, expanding collets and special arbors.
Machine Structure: Extended axis travel or modified working dimensions for specific workpieces, where technically feasible.
CNC Functions: Customized machining cycles and CNC macros for specific gear processes.
Electrical Integration: PLC interfaces and communication functions adapted to the customer's production system.
Tooling: Hob cutters, deburring equipment and related tooling packages can be supplied according to the project.
Quality Control
Xuanman applies quality control throughout component machining, assembly and final inspection. Machine-axis accuracy can be checked using laser interferometer equipment, with ballbar testing and gear inspection available according to the machine model and project requirements.
The company operates under an ISO 9001 Quality Management System, and Factory Acceptance Testing (FAT) can be arranged before shipment based on agreed acceptance criteria.
Technical Support
Xuanman provides technical support from machine selection through production preparation. Engineers can review workpiece drawings and evaluate machine configuration, machining process, tooling, workholding and production requirements.
Sample machining can be arranged for suitable projects before purchase. Xuanman can also provide foundation and utility requirements, installation support, operator training and relevant machine documentation according to the project scope.
After-Sales Service
Xuanman provides remote technical support for machine operation, troubleshooting and production-related issues. On-site service can be arranged when a problem cannot be resolved remotely.
Spare parts, preventive maintenance, control-system updates and technical consultation for new workpieces or production changes can be provided according to the machine configuration and service requirements.
Frequently Asked Questions
Q: How do I choose the right gear hobbing machine model?
