The GT-10 lathe from Haas is designed for medium-sized shops that need a versatile machine for short-run, secondary applications. According to the company, the lathe’s footprint of 5' × 5.3' and maximum capacity of 10" × 8" makes it useful as a “chucker” for shops with limited space. The machine has a maximum part swing of 12.65" over the front apron and a 12.75" swing over the cross slide. The X axis provides 6" of travel with 2,400 lbs of thrust, while the Z axis provides 8" of travel with 3,700 lbs of thrust. The rapid traverse rate is 710 ipm in both axes.
The lathe comes standard with a maximum spindle speed of 3,000 rpm. The company’s custom 7.5-hp vector dual-drive system provides peak torque of 42 foot-pounds. On-the-fly, wye-delta switching delivers higher torque and a wide constant-power band for constant surface-speed cuts, the company says. The A2-5 spindle nose has a 1.38" bore and accepts various optional through-hole chucks and collets, while the cross slide accepts gang-style tooling. In addition, the lathe features a large headstock casting for rigidity and an embedded tray for chip removal.
For higher productivity, the lathe is available with a pneumatic 5C clamping system that includes a spindle nose, rotating union and drawtube. This increases spindle speed to 4,000 rpm. An eight-position, bolt-on style automatic tool turret can hold a combination of 0.75" OD or 1" ID tooling. Other options include a two-position, quick-change tool post for 0.75" OD tools, a high-volume coolant system, user-definable macros, a floppy drive and 16 MB of memory.
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.
