New Hard Turning Investment Allows New Ballscrew Sizes

Kuroda Jena Tec's most recent investment in hard turning technology has increased production capacity with the combined benefits of efficiency compared to conventional production methodology as well as the advantage of development of higher diameter to lead ratios than able to be produced by conventional production techniques in a single ballnut housing. The ability to hold precision ground tolerances with turning technology is due to the unique design and capability of a Mikroturn slantbed CNC machine from Hembrug Machine Tools.
Hard Turning refers to the process of single point cutting of hardened pieces within the 2 micron range with hardness between 58 and 62 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? Greater accuracy Finish hard turning allows you to machine parts in one set up giving greater accuracies especially on features such as concentricity, squareness and roundness. More Flexibility 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. Higher productivity 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. Cost saving 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.
