Altogether 65 successful years.

Boring deep holes presents a special challenge for tools. With large length-to-depth ratios, the process has to be optimally planned, especially for hardened steel. Required is a combination of high process speed and top boring precision, journalist Bernhard Kuttkat reports.

Exeron has recently introduced its EDM 313 machine, featuring the company's eroding control MF30 as well as an automatic change system for electrodes and pallets.

Enemac's power clamping screw, type ESS, with its innovative force-intensified system enables manual and easy handling of low-tightening torques with resulting high-clamping forces, the company says.
