New boring tool improves security and productivity
Engineering360 News Desk | July 09, 2019Cutting tool and tooling system developer Sandvik Coromant has launched the CoroBore 825 dampened fine-boring tool based on Silent Tools technology, with dampers dimensioned to suit every adapter size. This solution improves process security where vibration issues are frequently encountered, such as when machining with long overhangs.
The boring head material has been switched from steel to aluminum, and the head has been shortened so that the damper comes closer to the cutting edge, which is beneficial for process stability.
CoroTurn insert carriers for the new tools have entering angles at 92° to 95°. This design increases stability due to reduced tool assembly deflection, making it possible to approach the bottom of a blind hole without engaging a greater part of the cutting edge.
CoroBore 825 is ideal for all fine-boring applications, covering diameters from 19 mm to 167 mm (0.75 in to 6.57 in), while a new assortment of cartridges can be utilized for back-boring applications. During back boring, the same internal coolant flow to the cutting edge is offered as in conventional boring.
