EcoLine boring tool with inbuilt ER connection lowers tool costs
Swiss Tool Systems develops clamping concept with outstanding rotational accuracy(PresseBox) ( Bürglen, )
"The new ER (DIN 6499) connection provides users with a rigid tool for finish-boring that works in a similar way to HSK connections in terms of the clamping principle," explains Peter Heinemann, technical head at Swiss Tool Systems. The new EcoLine boring tools developed by the Swiss precision tool manufacturer can be directly connected to standard ER collet chucks, as used worldwide. The monoblock system consists of a boring tool with an inbuilt chuck cone and is simply screwed onto the clamping device using the clamping nut. The tool and the chuck cone of the clamp form a single unit. The resulting cone and face contact is extremely rigid, thus ensuring high precision.
Stable connection similar to HSK-T and BIG PLUS® with significant cost savings Additional clamping elements such as collets are not required. The ER system's chucking capacity is also significantly greater, as the clamping nut is built into the connection. For instance, the Vario-Head boring tool can be used with clamp size ER40, suitable for boring holes with diameters of 3-152 mm.
As well as higher accuracy, users also benefit from significant cost savings, since they no longer need to pay for an adapter, extensions or reductions. "If you think about how common ER connections are in companies around the world, the level of potential savings quickly becomes apparent," comments Heinemann. And as the Swiss manufacturer is also selling the monoblock tools at an attractive price, this world first could quickly become a hit on the market.
