SUPER-PRECISION is a combination of best practice design and manufacturing of hardware and software integrated into a machine tool that produces the highest level of precision turning centers for production that require the least amount of human intervention in the marketplace today.
Key differentiators that set Hardinge SUPER-PRECISION Turning Centers Apart:
High static stiffness defined by SP accuracy requirements. It was qualified by Finite Element Analysis.
High dynamic stiffness defined by SP roundness and surface finish requirements. It was qualified by Structural Dynamic Analysis.
Composite Harcrete reinforced cast iron (Meehanite) base for superior torsion and bending stiffness and vibration damping.
High precision spindle bearings for collet-ready spindle design
High quality and oversized linear guides and ball screws
High accuracy (0.01micron resolution) digital glass scales
Robust control/wraparound motor/drive package with 0.1 micron (0.000010) resolution.
Turret with BMT Topplate for high stiffness (rigidity)
Built-in thermal management system (fans, chillers, strategically placed insulation) for machine thermal stability.
Detached utilities platform to reduce the effect of heat and vibration from control and hydraulic system has on machine accuracy.
In Manufacturing and Inspection:
Scraped joints for high stiffness and accuracy
Ground surfaces for linear rails for high straightness of linear motion
Two plane dynamic balancing of the spindle assembly resulting in parts with high roundness and surface finish
Laser inspection and compensation of positioning and straightness for X, Y, and Z axes
Ball bar testing for superior geometric accuracy verification.
Minimum step incremental test to verify machine drive system compensation capabilities.
High accuracy of machine geometry: (ISO 230 Standard) - up to 2 micron( 0.000080) X position accuracy; - up to 3.5 micron( 0.000140) Z position accuracy; - up to 2.5 micron( 0.000100) X straightness; - up to 2.5 micron( 0.000100) Z straightness; - up to 2.5 micron( 0.000100) Z axis alignment to spindle axis.
High roundness (circularity) capability up to 0.25 micron (0.000010);
High cylindricity capability up to 0.5 micron (0.000020)*;
High surface finish capability up to 0.15 micron (0.000006)*;
Unequaled hard turning capability
Unmatched straightness and position compensation capabilities
