Hardware · `NVGH-22T` · verification: source checked

The NVGH-22T is a vertical multi-process CNC grinding machine. The workpiece sits vertically, with a swing diameter of 2,250 mm and a maximum grinding diameter of 2,200 mm, and grinding is performed by a single HSK-A125 grinding spindle mounted on a turret with a continuously indexing B-axis. An optional turning spindle allows hard turning for stock removal, and an optional direct-drive C-axis on the work spindle enables non-round grinding.

## Study notes

- Control and software alternatives listed as FANUC; no specific FANUC controller model is named in the document.
- Machine is a 1-spindle specification; the grinding spindle is carried on a turret with continuous indexing (B-axis).
- Maximum grinding diameter is 2,200 mm and maximum grinding length is 600 mm.
- Maximum workpiece height is 700 mm.
- Work spindle maximum speed is 100 rpm; grinding spindle maximum speed is 6,000 rpm.
