YS7260 CNC Worm Wheel Grinding Machine

The machine tool is mainly applied to the precision grinding of gears in the industries of automatic transmission, aerospace, passenger cars, commercial vehicles, precision gearboxes, etc. The batch machining accuracy can reach 4-5 levels of GB/T10095.1-2008 standard (the actual machining accuracy is subject to the technical agreement signed by both sides with the user).

The main performance and characteristics of the machine tool:

◆ The machine tool is a twelve-axis five-linkage CNC gear grinding machine. This series of gear grinding machine is Chongqing machine tool and the British PTG (HOLROYD) company in strict accordance with the European high-end precision machine tool development process of the development of full CNC precision and efficient worm gear grinding machine. ◆ The grinding wheel spindle adopts German original imported high-power direct-drive electric spindle, and each linear axis adopts imported high rigidity rolling linear guideway.

◆ The software of the machine has perfect functions, and it can realize various complex shaping functions, such as arbitrary tooth direction shaping, tooth surface distortion compensation, point shaping (arbitrary tooth shaping shaping shaping shaping), tooth surface mesh grinding, double-pressure-angle asymmetric gear grinding, and small-bevel gear grinding.

◆ The machine adopts Siemens 840Dsl system, which flexibly controls twelve CNC axes through the system’s multi-channel control platform, realizing the full-automatic control of the whole machining process, including automatic clamping of workpieces, automatic dressing of grinding wheels, high-speed gear alignment, automatic grinding demonstration, automatic dressing demonstration, automatic margin allocation and automatic grinding.

◆ The right side of the machine is equipped with a single-station changing bin and a rotary manipulator, which can realize automatic loading and unloading of workpieces and save the auxiliary time for loading and unloading workpieces.
