The ST-20SSY high speed turning center features a Y axis, C axis and live tooling to provide a four-axis solution for “done in one” machining of turned parts.
The turning center has a maximum cutting capacity of 10" × 20.5", with maximum swings of 31.75" over the front apron and 20.75" over the cross-slide. It provides 4" of Y-axis travel (±2" from the center line) for off-center milling, drilling and tapping. Also, the center is equipped with high-torque live tooling and a servodriven C axis for four-axis capability. The 24-station hybrid BOT/VDI turret indexes tools in 0.5 sec. for reduced cycle times.
Equipped with an A2-6 spindle nose, the turning center features a 3.0" spindle bore; a bar capacity of 2.0"; and an 8.3" hydraulic, three-jaw chuck. The machine’s 30-hp vector, dual-drive spindle spins to 5,000 rpm and provides 115 foot-pounds of torque at 1,380 rpm. On-the-fly wye-delta switching yields a constant-horsepower band for constant surface feed cuts, the company says. Rapids are 1,200 ipm on the Z axis, 945 ipm on the X axis and 709 ipm on the Y axis.
Additional equipment includes rigid tapping, spindle orientation, a 15" color LCD monitor and a USB port. Other available equipment includes a belt-type chip conveyor, programmable hydraulic tailstock, automatic tool probe, an automatic parts catcher, high-pressure coolant systems and more.
Robot-Fed Multitasking Lathe with Conveyor
This machine can run for a long time without any operator intervention, and users can machine finished parts from slug stock or cast blanks while achieving the same high productivity as if they were machining from barstock, the company says.
