The Yama Seiki Goodway GS-3000 series turning center features a 30-degree true slant bed box way design, is engineered for heavy duty cutting of large work pieces up to 22" in diameter. The optional live tooling, C-axis, Y-axis, and sub-spindle satisfy the demand for a small footprint heavy duty machine with milling, drilling, and front/back-end turning application capabilities. Off-center milling, drilling and tapping can also be accomplished with Y-axis, with travel of 100mm (±50 mm from the center line). The widely spaced box way design provides the rigidity needed for heavy duty and interrupted turning applications and the large spindle bore is suitable for today’s oil industry, the company states.

The low center of gravity 30-degree slant bed design not only provides smooth chip disposal and easier operator access, but also provides the most rigid foundation for the headstock, turret, tailstock, and sub-spindle, according to the company. The rigid design enables long-term-high-precision turning.

Equipped with an A2-8 (A2-11) spindle nose, the turning center features a 4.15" spindle bore; a bar capacity of 4.13"; and 15” hydraulic, three-jaw chuck. The machine’s 30-HP, High Torque (Fanuc P motor) Spindle spins to 2,500 RPM and provides maximum 852 foot-pounds of torque. Machine’s Rapid of 1200 IPM on X axis and Z axis.

The standard 12-station turret with 0.3 sec indexing time and the optional 12 station live turret bring the GS-3000 series the capabilities that allow many turning applications to be completed in one machine, decreasing the loss of accuracy that occurs when a part is transferred manually from one machine to another.
