The Hardinge T-Series turning centers are the recognized market leader in Super Precision and hard turning applications providing superior SPC (Statistical Process Control), precise micron part size control and repeatability, high surface finish capability, and thermal stability with minimal human intervention allowing the most complex parts to be manufactured to the highest precision and quality standards. 

• “Soft turn” and “hard turn” on the same machine 

• Less floor space requirement 

• Lower overall investment 

• Metal removal rates of four to six times greater 

• Eliminate operations 

• Multiple operations in a single setup 

• Finer micro finishes 

• Easier Part configuration changes 

• Lower cost tooling inventory 

• Easier waste management (chips vs. “swarf”) 

SUPER-PRECISION® is a combination of best practice, design and manufacturing of hardware and software integrated into a machine tool that provides the highest level of precision for production turning centers that require the least amount of human intervention in the marketplace today.

Key differentiators

  • High degree of machine stiffness qualified by Finite Element Analysis
  • High surface finish capability of eight micro-inch or better
  • Ball bar testing for superior geometric accuracy
  • Dynamic balancing of spindle and drive motor
  • Integral wrap around spindle motor technology to eliminate belts
  • Matched high precision spindle bearings
  • Ability to maintain 0.00012” 3 micron total deviation in diameter after a brief warm-up
  • High repeatability accuracy – 30 millionths (.00003”)
  • Robust control/motor/drive package with 10 millionths (.00001”) control resolution
  • High accuracy X-axis digital glass scales

Collet-Ready Spindle Advantages

  • Collet seats directly in the Hardinge spindle
  • Maximum rigidity and gripping power is transferred to the part
  • Maximum utilization of RPM
  • Minimum weight on spindle
  • Minimum overhang from the spindle bearings that assures spindle accuracy is transferred directly to the workpiece
  • Optimum T.I.R.
  • Gripping force directly over the workpiece
  • Superior tolerances and finishes
  • Capable of using maximum machine stroke capacity
  • Longer tool life
  • Quick changeover

Live Tooling

Live tool holders start at 8,000 RPM and are capable of up to 32,000 RPM when purchased with ratios
of 2:1 or 4:1 when high speeds are required.The Hardinge BMT live tooling holders provide superior run-out within .00012” (3 micron) making it the overall best in class tooling system.
