The CH7516GS is BOCHI's high-speed turning center on a 45-degree slant bed, developed for turning-to-grinding-class finishes. An A2-5 spindle reaches 8,000 rpm, and a 12-station turret with six driven tools pairs with a 0.001-degree C-axis.

Why turn at 8,000 rpm instead of grinding?

Grinding a small precision part means a second machine and a second setup, and the part travels between them. The CH7516GS's 8,000 rpm spindle cuts to a finish that replaces grinding, so a 250 mm part comes off in one clamping — the speed and surface that let turning substitute for grinding.

• 450 mm swing, 250 mm turning diameter
• A2-5 spindle, 8,000 rpm, 15/18.7 kW
• 12-station turret, 6 driven tools
• C-axis 0.001°, 42 m/min rapids

Against a lathe plus a grinder, the CH7516GS cuts to a ground-class finish in one setup — the reason a medical or aerospace part skips the grinding step.
