Hard turning vs. grinding
Hard Turning refers to the process of single point cutting of hardened pieces within the 2 micron range with hardness between 58 and 70 HRC. Hard turning has proven to be worthy alternative to the more expensive and time consuming grinding.
Finish Hard Turning: Why it is the alternative to cylindrical grinding?
Finish hard turning allows you to machine parts in one set up giving greater accuracies especially on features such as concentricity, squareness and roundness.
With a single standard tool and clamping set-up you can machine a wide variaty of products with different forms and sizes. This provides more flexibility in production environments and reduces changeovers.
Finish hard turning can remove more material per machining operation than grinding.
This can make hard turning up to 3 to 4 times faster when compared to cylindrical grinding.
Multiple operations can be done in one set-up which eliminates the need for a multi-step grinding process that historically would involve two or three seperate operations.
