Efficient gear milling machine
High-efficiency gear milling machine is a cost-effective cutting machine developed by domestic and foreign customers for large gear processing. It can be used for roughing and finishing of finished products before hobbing. It is mainly used in wind power, engineering machinery, mining machinery and other fields.
The gear milling machine adopts a forming tool cutting gear with the same groove shape as the gear to be machined, that is, the cutting edge shape of the tool used coincides with the groove shape of the gear to be cut. It is mainly used for roughing, heat treatment first half finishing and final processing in some industries.
The core components of the high-efficiency gear milling machine are the milling head and the workbench, which are the top priority to ensure the accuracy, efficiency and stability of the gear milling machine. The GM series high-speed gear milling machine is realized through modularization on the basis of the gear hobbing machine, that is, the hobbing frame is replaced with a high-rigidity milling head. The workbench is the same as the GH series gear hobbing machine, and the machine tool has high processing efficiency, good stability and high accuracy.
