Four-Axis CNC Vertical Spindle Forming Grinder
GV-760/GV-800
The machine tool is mainly used for surface processing of workpieces such as outer circles and inner holes of circular bosses, special-shaped outer circles of flanges, inner side surfaces of grooves, and annular linear guide rail raceways.
- The machine tool has a total of four CNC axes. X, Y, and Z are linear axes, all of which adopt linear guideways and ball screw structures. The X-axis adopts a floating nut structure authorized by a national invention patent. The C-axis is a DD direct-drive hydrostatic turntable equipped with a Renishaw RESA absolute high-precision circular grating, ensuring high rotation accuracy and repeatability.
- The machine tool is equipped with the Huazhong 848Di five-axis CNC system as standard, which can be controlled independently or in four-axis linkage, and has functions such as linear interpolation and circular interpolation.
- The grinding head structure uses a high-power electric spindle, and the grinding wheel tool holder is loosened and locked by a hydraulic cylinder, making the grinding wheel replacement convenient and fast.
