The new Mini's now compatible with the Hainbuch modular system

Added to MTDCNC by HAINBUCH UK Ltd on 24 November 2015

Sometimes small things turn out to be a big success. In fact the overwhelming success of the Hainbuch mini chucks has now driven the company's engineers to make them compatible with the renowned Hainbuch modular system. 

Hainbuch has now engineered a solution that makes its mini chucks compatible with both series of chucks, the round Spanntop and the hexagonal profile Toplus. With its reduced interference contour, to use the modular system with the Spanntop mini chuck requires an adapter ring. Whereas the existing Mando Adapt mandrel and jaw module work perfectly with the new Spanntop mini. The Toplus version does not use an adapter ring, instead it has a ring of attachment holes for fixing the jaw module. From 2016, this series will get its own Mando Adapt series of adapters. In addition, the Spanntop and Toplus minis both have full through-bore facility and they are available in three standard lengths to suit all machines and drawtubes.

Reduced clamping device interference contour and less mass

These two factors play an ever more important role in any machining process. Tool accessibility and low energy consumption are key criteria for modern workholding. So, this makes them ready for the challenges of the future. Increasingly parts have smaller dimensions and higher tolerances than in the past, so the emphasis is no longer on the chuck size but rather on the complete process.

Thanks to greater tool accessibility, the mini chucks can use shorter and more stable tools on the main and counter spindles. This has a direct influence on the surface finish. Not only is the mass reduced by over 38%, the chuck diameter and the total length has also been considerably reduced by over 25%. So, the 'little' chucks make a 'big' difference. The reduced interference contour makes it easier to choose the right tool and this helps with the issue of reduced space especially in counter spindle machines. The reduced mass also results in lower energy consumption especially in mass production. Furthermore, with spindle acceleration and deceleration being more dynamic, cycle times are shortened and all this contributes to lowering the cost per workpiece.
