2m Dia Large CNC Helical /Internal/External Spur Gear Milling Cutting Machine

Product Description

Process matching
Rough milling
Large cutting depth and appropriate metal removal rate are suitable for the rough processing of gears
Semi-finishing milling
Using semi-finishing milling cutter discs on the machine tools equipped with fine milling can meet the requirements of efficient processing before grinding, optimize processing efficiency and comprehensive costs.
Fine milling
Using fine milling cutter discs on the machine tools equipped with fine milling can achieve GB8 level accuracy
Process combination
Rough milling-fine milling
The tool change process on the same equipment can complete the entire processing process of the workpiece, and the fine milling cutter disc can also be directly used for processing and forming.
Gear milling-gear grinding
For high-precision and high-hardness workpieces, semi-finishing milling cutter discs are used, and small normal allowances are left for milling teeth, and gear grinding is performed.
