Drilling & Boring

Very deep, complex holes are becoming increasingly challenging to machine as hole tolerances become tighter and surface finish requirements get finer.

Improved holemaking efficiency drives powertrain machining throughput.

Sandvik Coromant's Global Center for Deep Hole Machining offers a tip for machining the central bore in the main shaft.

Adjustable finish boring heads allow for a range of diameters to be machined with one tool. Finish boring can take some time but achieves tight hole tolerance and fine surface finish requirements. And if a fine finish and tight tolerance are not required, rough boring might suffice.

BIG Kaiser's 319 SW series is a rigid, new style, twin cutter rough boring system.

Pinzbohr High Precision Modular Boring Tools from Techniks are unsurpassed for accuracy, rigidity, and repeatability.

New technology opens up new applications for small HMCs.

Machining a clean, straight and in-tolerance hole through a part is not the only requirement for many holemaking applications. In many cases, hole entrances and exits are also critical to part functionality.

Drilling stacked materials, which have alternating layers of composites and metals, requires a careful strategy and the right tools.
