Goodway GS-6000

The Goodway GS-6000 is a heavy-duty slant-bed lathe that turns Ø880 mm (34.6 in) and up to 3,300 mm (129.9 in) long. In the three-model GS-6000 series it is the small-bore, fast-spindle version: Ø115 mm (4.5 in) bar capacity, 15 in or 18 in chucks and a high gear range that reaches 2,000 rpm.

Goodway builds the series on a 45° true slant bed with over-sized box ways. The spindle is driven through a 2-step gearbox by a motor rated 30 kW (40.2 hp) continuous and 37 kW (49.6 hp) for 30 min., and the maker quotes 4,300 Nm of maximum spindle torque. Low range tops out at 550 rpm.

Three beds are listed, with Z travel of 1,050 mm (41.3 in), 2,020 mm (79.5 in) or 3,300 mm (129.9 in) and turning lengths of 1,020 mm (40.2 in), 2,000 mm (78.7 in) and 3,300 mm (129.9 in). X travel is 500 mm (19.7 in), or 520 mm (20.5 in) with the live tooling turret. The tailstock base moves 790 mm (31.1 in), 1,790 mm (70.5 in) or 3,200 mm (126.0 in) to follow the bed.

Only one variation exists, M, which adds C-axis control and a 12-station live tooling turret. It is a serious one: ER50 collets, 10 ~ 3,000 rpm and a 9 kW drive that Goodway compares with a standard machining center. There is no Y-axis or sub-spindle in this series. The 2,000 rpm high range is what sets this model apart from the GS-6600, which is limited to 1,100 rpm.
