Hainbuch Compatible mini chucks save energy, reduce costs
Germany – Hainbuch has engineered a solution that makes its Spanntop and Toplus mini chucks compatible with its established modular system.
According to the company, the round Spanntop requires an adapter ring; Hainbuch's Mando Adapt mandrel and jaw module work perfectly with the new Spanntop mini. The hexagonal profile Toplus version does not require an adapter ring but relies on a ring of attachment holes for fixing the jaw module, the company adds.
This year will see this series get its own Mando Adapt series of adapters. Both Spanntop and Toplus minis have full through-bore facilities and are available in three standard lengths. They are designed to suit all machines and draw-tubes, the supplier says.
The UK-based company also notes that its mini chucks can use shorter and more stable tools on the main and counter spindles, which has a direct influence on surface finish. Mass of the units has been reduced by over 38%; chuck diameter and total length have also been reduced, by over 25%.
The reduced mass is claimed to deliver lower energy consumption, while more dynamic spindle acceleration and deceleration can help deliver shorter cycle times and this allows for costs to be cut per workpiece too.
Reduced interference contour, the company says, makes it easier for the device to choose the right tool as well as help with issues of reduced space, especially in counter spindle machines.
