YT7226 Double Table Gear Grinding Machine

The machine tool is mainly applied to the precision grinding of gears in the industries of new energy vehicles, automatic transmissions, aerospace and passenger cars, etc. The batch processing accuracy can reach the level 4-5 of GB/T10095.1-2008 standard (the actual processing 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 thirteen-axis control five-axis linkage CNC worm gear grinding machine. The machine tool adopts double workpiece spindles, which can shorten the cycle machining auxiliary time to less than 5 seconds and greatly improve the production efficiency.

◆The machine tool adopts high-precision endface tooth disk plus hydraulic floating tensioning device for high-precision positioning and locking of table exchange, and the consistency of machining accuracy of front and rear table is within 0.005mm.

◆The bed circulating cooling heat balance system adopts different oil flushing methods to balance the internal temperature of the machine tool and reduce the thermal deformation during machining and non-machining.

◆ The software of the machine tool has perfect functions, which 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 taper gear grinding;

◆The machine tool adopts Siemens 840Dsl numerical control system. Through the system’s multi-channel control platform, it flexibly controls each numerical control axis, realizing the full-automatic control of the whole machining process, including automatic clamping of workpieces, automatic dressing of grinding wheels, high-speed gear setting, automatic grinding demonstration, automatic dressing demonstration, automatic margin distribution and automatic grinding.
