Hardinge, Hard Turning
August 16, 2012
When considering hard turning, the question is not “Can it be done?” because many machine tools can hard turn. Instead the question is, “How well can it be done?” Success in hard turning is largely a measure of the machine construction and design along with the workholding and tool holding. The level of rigidity and damping in a hard turning application cannot be minimized. That’s where Hardinge has a competitive advantage.
Success in Hard Turning is defined by a number of factors:
Rigid cutting tools and advanced insert materials Hardinge lathes meet these requirements with the following key features.
QUEST lathes are built on a rigid cast iron base with HARCRETE Polymer Composite reinforcement. Vibration damping is critical to the successful application of hard turning. HARCRETE is located in key positions of the base to assure maximum rigidity. This unique design can help you save 30% or more on cutting tool expenses, and reduce vibration at the spindle by 60%.
All external tools on QUEST machines equipped with Hardinge turrets mount directly into the tool slots provided in the turret body. The close proximity of the cutting tool to the coupling reduces the risk of vibration, thus improving the Hard Turning process.
In short, Hardinge machines offer the ideal machining process from the standpoint of part cost, capability, and accuracy.
