The GVP-8040 Vertical Gear Profile Grinding Machine applies the FANUC controller and high-speed grinding spindle;through the Matrix Precision-developed intelligent conversations window software, it can flexibly output the required tooth profile and grinding parameters. The workable machining workpieces include the involute gears, large-module hobs and cycloidal gears.

GVP-8040 applies the globally famous FANUC controller. It combines the direct drive motor and 8-axis close-loop servo system; each axis can simultaneously run to obtain a high-precision performance.

GVP-8040 is built in vertical construction, which enables mitigating the bending/deforming effect of large workpieces from gravity and building a more stable gear grinding process.
