A competitively priced, fully integrated 2- or 3-axis collet ready spindle lathe with options of automatic load/unload gantry with a 10 platen patented modular magazine has been developed by Hardinge Machine Tools of Leicester ready for launch at MACH 2010. The Hardinge GS51A machine with its GS Performance Plus Package and gantry part exchanger has been developed as a compact production cell taking just 3.1m by 1.5m of floor space. It is available for under £80,000 as a ready to run operational cell using the Hardinge collet ready spindle with a maximum machining diameter of 284mm by 456mm turned length. The 12 station turret can also be upgraded with C-axis positioning and a driven tool option. The double gripper, vertical gantry loading arm interfaces with an external patented 10 platen slant magazine located at the headstock end of the machine with each platen able to accept multiple parts. The system has automatic centre position adjustment for component pick-up and deposit after machining. It takes just nine seconds to exchange the component with either the Hardinge high rigidity collet system that maintains the component in close proximity to the spindle bearing arrangement to maximise the influence on roundness, concentricity and surface finish. As an option a three jaw chuck can be specified. Rapid traverse rates are 30m/minute in X and Z axes. There are customer specified options of Fanuc or Siemens control and drives packages with the machine. The Fanuc 0iTD control and drives provide an 18.5kW spindle motor giving 5,000rpm and 210Nm of torque while the alternative Siemens 828D system delivers 25kW, 5,000rpm and 205Nm of torque. A wide range of options include bar feed in place of the loading gantry system giving 100mm maximum machining diameter by 120mm turned length. Driven tools, a fully programmable tailstock, arm type fully covered parts catcher, automatic tool probe, hinge or scraper swarf conveyor and high pressure 20 bar coolant system are also available.
