CNC Worm Wheel Grinding Machine
Introduction
The Y7250 CNC Worm Wheel Grinding Machine is a high - precision machining equipment specifically engineered for the mass production of hardened cylindrical gears in both shaft - mounted and disc - type configurations.
This machine is capable of grinding gears with complex geometries such as crowned teeth and tapered teeth, which are crucial for applications demanding high - precision power transmission.
It can perform gear grinding operations using a diamond - tipped hob that precisely replicates the gear profile. Not only ensures accurate tooth form generation but also enhances the surface finish and dimensional accuracy of the gears, meeting the stringent requirements of industries such as automotive, aerospace, and heavy machinery.
Product Features
- Ergonomic Workpiece Handling Mechanism: The table, tailstock, and dresser are ingeniously integrated onto the rotary table. Through precise positioning of the rotary table and controlled rotation to bring the workpiece within the operator's immediate reach, the loading and unloading processes are significantly streamlined. This design not only enhances operational efficiency but also minimizes the risk of handling errors, ensuring a smooth workflow in the production environment.
- Advanced Shift Grinding Technology: The machine employs the shift grinding method, a sophisticated approach that capitalizes on high - speed rotations. The grinding wheel spindle can achieve a maximum speed of 7000 rpm, while the dressing roller operates at a speed range of 3000 - 6000 rpm. This combination enables high - speed and high - efficiency grinding operations, substantially boosting the overall productivity of the manufacturing process. The optimized grinding parameters and the shift grinding technique work in tandem to deliver superior surface finishes and dimensional accuracies.
- State-of-the-Art Technological Integration: By incorporating cutting - edge technologies such as direct drive of the electric spindle, online dynamic balance of the grinding wheel, and full closed - loop control, the machine attains remarkable levels of accuracy. The direct drive system eliminates power transmission losses and enhances the spindle's responsiveness, while the online dynamic balance system ensures consistent grinding performance by compensating for any imbalances in real - time. The full closed - loop control system continuously monitors and adjusts the machine's movements, guaranteeing high positioning accuracy, precise transmission, and excellent grinding precision. These features collectively meet the stringent requirements of high - quality production and processing.
- Intuitive and Versatile Operating Interface: The machine's operating interface is developed based on the Siemens 840DSL system with in - depth customization. It offers a high degree of flexibility for tooth trimming, accommodating any complex tooth shape. This versatility simplifies the programming process and reduces the skill level required of the machine operator. Even operators with limited experience can efficiently operate the machine to achieve accurate tooth profile modifications, thereby enhancing the overall usability of the equipment.
- Enhanced Automation Capabilities: The machine can be optionally equipped with robots (either truss - type or articulated - type) and silos. This automation setup further increases the degree of automation in the manufacturing process. The robots can perform tasks such as workpiece loading and unloading, tool changing, and quality inspection with high precision and repeatability. The silos provide automated storage and retrieval of workpieces, ensuring a continuous supply of materials. This combination not only improves machining efficiency but also significantly reduces the labor intensity of workers, allowing them to focus on more value - added tasks.
