H400G
The H400 G is designed for small to medium batch production, suitable for workpieces with an outer diameter between 200 mm and 400 mm, as well as shaft parts up to 500 mm in length.
The H400 G is equipped with a single workpiece spindle, which, like the H260 G, is mounted on a rotary table. This configuration simplifies workpiece loading/unloading and tool handling. The same rotary table features a dressing device opposite the workpiece spindle, capable of dressing both conventional grinding wheels and cubic boron nitride (CBN) wheels.
Key Features:
+ Suitable for small to medium batch production
+ Simplified workpiece loading/unloading and tool change operations
+ High flexibility during grinding and profile machining
+ Capable of machining gears and shafts (optional tailstock)
(1): Using profile grinding wheels (without generating method)
(2): Workpieces cannot be loaded/unloaded by crane; weight limits are specified by the workpiece lifting system
