Tool manufacture
Reductions in whole numbers

Precision is everything in tool manufacture Blanks and tools must be positioned at high speeds with micrometre precision. The complete machining in one clamping prevents imprecision, which can creep in through the frequent re-clamping of a workpiece. Compact precision gears with reduction in whole numbers provide for the exact positioning of the chain or disc magazine loaded with the various tools. Nabesco designed its RA series especially for the drive of such magazines in tool manufacture. On the basis of the reduction by the RA gears in whole numbers, the servo motor with its input shaft and the drive with the output shaft are always in the same position. In doing so, an absolutely precise positioning is always provided. A repetition of imprecisions and their exponentiation through the continuous rotation of the chain magazine in the same direction are eliminated.
