PRODUCT NEWS Affolter Introduces Gear Machines for Watches & Medical Instruments Affolter Technologies SA of watch industry. Malleray, Switzerland, has introduced Affolter Pignons, which today a new line of gear hobbing and micromilling manufactures more than 30 million machines for the manufacture gear trains per year, created its own of small gears, worms and similar demand for new and updated machine parts used in watches and medical tools. So, in 1991, Affolter Pignons and dental instruments. started up a new, separate company The Gear AF100 gear cutting center, to develop its machine tool capa- introduced a year ago at EMO, bilities. That company is now Affolter is an eight-axis CNC gear hobbing Technologies SA. In the beginning, machine for cutting parts up to 36 Affolter Technologies worked mainly mm diameter and 50 mm length. The on machine retrofits, working with machine can cut spur, helical, tapered lathes and gear hobbing machines. or convex teeth on gears, shafts and In 1996, Affolter entered into a pinions, either by hobbing or toothby-tooth partnership with Wahli to develop using an indexed milling an eight-axis CNC hobbing machine. cutter. That machine was the Wahli W100. Parts are held between centers and are direct-driven by two independent motor spindles. The cutting tool is driven by a third motor spindle. All three spindles are electronically synchronized, with rotation speeds of up to 16,000 rpm. The Gear AF110 micro-milling center, introduced in September at the AMB show in Stuttgart, Germany, is designed scales for positive feedback, with system resolution less than 1 µm. Affolter has developed and built machine tools for more than 10 years, says Raymond Graf, sales and marketing manager. But until recently, those machines were manufactured for the use of sister company Affolter Pignons SA, a manufacturer primarily serving the Swiss However, about two years ago, Affolter decided to redesign the machine and begin marketing it under its own name, Graf says. Over time, Affolter Technologies has developed expertise in a number of areas of machine tool manufacture. The company makes its own CNC controls— including both hardware and software for gear hobbing, screw cutting development—as well as its and micro-milling. own spindles, “the most important The AF110 is also capable mechanical component of of hobbing gears up to 36 mm the machine,” Graf says. diameter and 50 mm length. “We wanted to master the However, unlike the AF100, whole technology,” Graf says. the AF110 has no tailstock “First we only did retrofits of motor spindle, which allows the existing machines, and finally, cutting spindle to be inclined we got all the know-how to up to 90° for machining worms, develop the machine completely.” straight bevel or face gears, bone screws and other medical The company has two more or dental tools and parts.
