Technical Specifications:
1. Motion Axis Configuration
Equipped with a 7 axis servo driven system and 2 frequency controlled axes, enabling multi-dimensional precision motion control. Key components include:
- X and Y axes driven by direct drive motors, eliminating transmission chain backlash to achieve micron-level positioning accuracy, ideal for high-efficiency and high-precision batch gear grinding operations.
- Workpiece axis integrated with a torque motor and hydrostatic structure, utilizing fluid hydrostatic support technology to reduce friction loss and enhance motion stability under heavy-load conditions.
2. Grinding Process Principles
Based on the profile grinding principle, the machine achieves high-efficiency gear surface machining through precise trajectory matching between the forming grinding wheel and the workpiece. Core functional modules include:
- Grinding wheel spindle with built-in wireless dynamic balancing device, which ensures grinding accuracy stability at high rotational speeds (up to [X] rpm) through real-time vibration monitoring and compensation.
- Dedicated software system for internal and external gear machining, supporting tooth profile correction and tooth direction correction, and enabling parameterized programming for complex tooth shapes such as involute gears and helical gears.
3. Intelligent Measurement and Automation Functions
- Contact-type gear alignment and in-process measurement device:
Integrated with high-precision displacement sensors and algorithms, it enables automatic workpiece alignment and real-time acquisition of key accuracy parameters (e.g., pitch deviation Δfpt, profile error ffα) through in-situ measurement. Results can generate ISO 1328-standard reports for printing.
- Menu-driven operation interface:
Features a graphical human-machine interface (HMI) that supports parameterized input and visual preview of process paths, minimizing operational complexity and reducing programming setup time.
4. Safety and Process Expansion Features
- External fire extinguishing system:
Equipped with an independent fire suppression module, providing rapid response to potential oil mist ignition risks in compliance with ISO 14120 machinery safety standards.
- Triple-section gear grinding capability:
Enables one-setup machining of multi-section gears, reducing workpiece handling errors and improving efficiency for complex-structured gears.
- Material allowance distribution function:
Automatically allocates rough, semi-finish, and finish grinding allowances via pre-set process parameters, optimizing grinding efficiency and surface quality (achieving Ra values as low as [X] μm).
- Dual internal grinding tool configuration:
Standard with one large and one small internal grinding tool, accommodating internal gear machining for different aperture ranges (φ[X] mm-φ[X] mm) and minimizing tool change frequency.
Technical Terminology Notes
- Servo Axis: A motion axis with closed-loop control, enabling precise regulation of position, speed, and torque.
- Frequency-Controlled Axis: An axis regulated by a frequency converter to adjust motor speed, suitable for auxiliary motions requiring speed stability.
- Profile Grinding: A machining method using a forming grinding wheel contoured to the workpiece, eliminating the need for generating motion and ideal for mass-producing standard tooth profiles.
- Hydrostatic Structure: A support system using pressurized oil films to minimize friction (coefficient as low as 0.0001-0.001), significantly enhancing rigidity and precision retention.
