In microtechnology, gear cutting is an operation adding value and if it is possible to realise the parts by different means, the use of a dedicated machine remains very often the best solution. Meeting with Mr. Sébastien Giran, responsible for marketing at Affolter Technologies SA.
“Gear cutting in small diameters is our specialty and we are able to propose the most effective solutions by offering the best quality to our customers” says the Manager to start. In this logic of answering to the needs of its customers, the company now presents two highly anticipated novelties:
- Double clamping with F10 collets on the AF 100 machine
- Offset system of the milling cutter on AF 110 for the realisation of wormscrews
Watchmakers looking for the solution The realisation of high quality castle-wheel and crown-wheel at high speed remained a problem to solve. …until today. Equipped with a pneumatic system of clamping force adjustable continuously, the device allows working on both sides with collet clamping automatically shifted from one side to the other. It’s easy to imagine the gain on cycle time, but what about precision? “As we align the two collets relatively one to the other with fine tuning, we guarantee concentricity and precision” says the manager.
New possibilities for (new) markets It is the first time that the opportunity to cut straight or helical wormscrews is available on Affolter machines. This option can be easily mounted on the B-spindle nose and moves the cutting tool of 90°. The milling cutter is then parallel to the part. The tilting axe of the milling cutter is the same as with a classical nose, i.e. between -45° / 30°, but with an offset of 90° (-135° / -60°). The flexibility of adjustment allows the realisation of wormscrews with a maximum length of 90 mm and maximum diameter of 60 mm with ease. This device will be presented at several trade shows taking place in the last quarter of 2014.
To be discovered in Germany, Italy and Japan It is a record year for Affolter Technologies in terms of exhibitions, since in 2014 the company is present at 14 events in 9 countries. The next opportunities to meet with the company’s specialists will be AMB, Bimu and Jimtof.
