The original machining capacity of 4 by 28 mm has been boosted to 7 by 50 mm and the spindle power more than doubled to 2.5 kW to enable the machine to process bars made from the hardest of materials.
The machining area has been re-designed and the available tooling expanded and optimised to enable numerous operations providing high added value. The small footprint and machine design means SwissNano 7 occupies the same space as a cam-type machine and so can increase output per unit area, compared to other CNC machines.
Says marketing manager Brice Renggli: "This ultra-compact production centre is unrivalled in the market; its machining area is extremely flexible and enables various configurations to be realised. No matter what challenge you have to face, the SwissNano is able to meet it.”
The 6-axis kinematics offer numerical adjustment of all tool positions in X, Y and Z directions. At the heart of the concept is the back spindle, mounted on three linear axes, making “the machine extremely user friendly”. The main platen includes three positions for the rotating tools; it can hold transverse drills, a polygon tool or a gear hobbing tool. This opens up the possibility of machining operations not previously possible on this range.
Says Philipe Charles, Tornos head of product management Swiss-type: “As a matter of course, the SwissNano 7 is equipped with the best kinematic system available in the market. The set-up of this compact-yet-efficient machine is extremely easy. Thanks to its unique design, the operator faces the counter-spindle, which makes set-up and centring work a breeze. The most unique feature of this kinematic system unquestionably is the counter-spindle that is controlled in three NC axes. This is the great strength of SwissNano's concept. Since it boasts an ultra-ergonomic design, it's a great pleasure to work with a SwissNano machine.”
The machine is ideal for the medical sector with the addition of a thread-whirling unit. For instance, it enables the machine to be used for the production of maxillofacial screws. In addition, it is an excellent partner when it comes to the production of screws for dental implants or straight implants. The machine can also be equipped with high frequency spindles for back machining operations. This permits the machine to mill hexalobular shapes (Torx).
The SwissNano 7 is also perfect for machining of connectors. It can be equipped with a slotting unit for back machining that enables split connectors to be tackled from both sides. Moreover, a polygon cutter can be installed for both main and back machining operations.
The machine also enables processes such as gear cutting to be performed during main and back machining operations. In addition to the two main tool systems, the machine is equipped with a tool holder under the counter-spindle. This enables front drilling operations to be done or it can even support the workpiece during the machining process.
