Product Overview

Meeting all requirements

Hardinge builds super-precision machines which are specifically designed to achieve extremely low tolerances and high surface finishes. The machine design allows for bringing the part closer to the spindle which is particularly beneficial in hard turning.

Our machines offer a particularly high level of stability & precision, excellent vibration-absorbing characteristics, extremely high rigidity of the tool holders, and perfect stability of the workholding facilities. SUPER-PRECISION hard turning by Hardinge opens up new opportunities to replace expensive and complex grinding processes without any loss in quality. Hard turning is faster, more flexible, needs shorter setup times, and requires less operations.

Where precision and power count, machines and clamping technology of Hardinge are the first choice - where other manufacturers fails we are only warming up.

Convincing all down the line

Compact and powerful CNC heavy-duty turning centers with Hardinge collet spindle, tailstock (option) and NSK V roller guideways in all axes. The optionally available Performance Plus package comprising glass scales in X and Y axis, main spindle cooling unit and heat exchanger at the hydraulic system paves the way for efficient hard machining. The collet spindle allows for the series production of workpieces offering an excellent surface finish within close tolerances.

Key features:

High precision
High series accuracy
Compact design
Long life
Flexibility thanks to various options like for instance
Performance Plus package (thermal stabilization)
Tailstock
C axis for contour milling
Rotary tools in all stations
Gantry loading system, machine-integrated
Automatic tool and part measurement
Control: Fanuc Oi-TD or Siemens 828 D
Performance Plus thermal stabilization Package comprising glass scales in X and Z axis, main spindle cooling unit and heat exchanger for hydraulic system

The Hardinge collets are directly inserted in the main spindle. This results in a minimum projection of the workpiece beyond the spindle bearings. One of the most important prerequisites for the spindle to transmit the guaranteed runout of 0,5 µm to the workpiece. At the same time, the rigidity of the clamping system is increased. This creates ideal conditions for the observance of form and positional tolerances.
