Analysis of Gear Milling Technology for CNC Centering Machines
I'm glad to answer your questions about gear milling on CNC centering machines!
The feasibility of hobbing with CNC centering machine
CNC centering machines can indeed perform hobbing processing, which is part of their comprehensive processing capabilities. Modern high-end CNC centering machines can complete gear processing techniques such as hobbing through the installation of special accessories and programs.
Specific implementation methods:
Special gear-cutting accessory: A high-precision gear-cutting power head accessory needs to be installed
C-axis + Y-axis linkage: The C-axis (spindle indexing) and Y-axis (radial feed) of the machine tool are used for synchronous control
Special programming: Special gear processing programs are required, usually using macro programs or dedicated CAM software Applicable scenarios
Small-scale precision gear processing (with diameters typically less than 42mm)
Small batch, multi-variety gear production
Requires compound processing that can be completed in one setup with other processes
Compared with traditional hobbing machines
Features: CNC centering machine hobbing, dedicated hobbing machine
Accuracy: Higher (6-7 grades) Much higher (4-5 grades)
Efficiency: Lower Higher
Flexibility: High (changeable production) Low
Cost: Additional functions Professional equipment Notes for Attention
The accuracy and efficiency of the centering machine hobbing machine are usually lower than those of the dedicated hobbing machine.
It is only suitable for processing gears with smaller module (generally not exceeding 1.5 modules).
Regular checks on the accuracy of the tools and accessories are required.
The processing parameters need to be optimized to avoid affecting the service life of the machine.
Do you need to know the specific programming methods for centering machine hobbing or equipment selection suggestions? Or do you have specific gear processing requirements that you would like to discuss further?
