The Yama Seiki Goodway GS-3000 series turning center featuring a 30-degree true slant bed boxway design is engineered for heavy-duty cutting of large workpieces up to 22" in diameter. The optional live tooling, C-axis, Y-axis and subspindle 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 100 mm (±50 mm from the center line). The widely spaced boxway design provides the rigidity needed for heavy-duty and interrupted turning applications.
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 subspindle, the company says. 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.
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.
