PolyEtherEtherKetone, known by the acronym PEEK, is a thermostable semi-crystalline polymer having properties that enable it to replace metal. It is used in lumbar surgery for the production of "disc/cage implants" (spacers) designed to replace damaged or unstable spinal discs. Different spacer sizes enable the surgeon to adapt the operation to the patient’s anatomy. Since PEEK is a radiolucent material (invisible to X-rays), two tantalum markers are inserted in the implant to allow precise, (...)

Riveting with extremely small dimensions
Riveting technology, like anything else, needs to keep up with the constant trend toward miniaturization. With the radial riveting machine RN 181 “reduced,” for delicate rivet connections, BalTec has a cutting-edge solution for this challenge, as well. The subtly designed kinematics of this machine allow rivet joints using even very small diameter rivets made of aluminum and fiber-reinforced plastics. It is possible to locate the rivet start when lowering the rivet tool onto the rivet at a (...)
