Rock solid performer

maximum cutting capacity of 533mm by 660mm with maximum swings of 806mm over the front apron and 527mm over the cross slide.

The ST-30 CNC lathe's standard 30hp spindle yields 275ft/lb of torque at 700rpm and spins to 3,400rpm. For heavy cutting operations an optional two speed gearbox increases torque to 840ft/lb at 200rpm. The A2-6 spindle nose is equipped with a 10 inch hydraulic three jaw chuck. The machine is equipped with a 12 station bolt on style tool turret and comes with a Y-axis and as a Super Speed version.

From a generic standpoint, Haas CNC turning centres are built from the ground up with productivity in mind. Large headstock castings with symmetric ribs for rigidity and stability are featured along with a two piece design for easy realignment, embedded chip trays for improved sealing and efficient chip removal, increased volume, roll out coolant tanks and double wall doors riding on precision bearings for smooth, reliable operation.

The turrets for Haas ST Series turning centres are finish machined as a unit and assembled complete with the coupling, gearbox and drive system. Keying off the turret's centreline, all critical features of each station are machined using single-axis moves and then the turret is indexed to the next station ensuring the concentricity of each station with the turret's true centre. Compared to machining the turret before assembly, this is said to reduce positional variation from tool to tool by more than 90% resulting in simpler job set-up, higher levels of accuracy and better repeatability.

High quality guides and ballscrews are used with the latter anchored at both ends and inspected for 100% parallelism to the axis guides. Preloaded ball nuts eliminate backlash.
The ST-30 will be joined on the Haas stand by a selection of the company's latest CNC technology, including a 2012 5-axis vertical machining centre.
