Festo has launched a series of electrical piston-rod cylinders that provide high accuracy programmable positioning capabilities. The new DNCE series electrical cylinders are mechanically 100% compatible with Festo’s DNC pneumatic cylinders, enabling machine designers and builders to implement mixed technology automation systems. DNCE series electrical cylinders are available in 32, 40 and 63mm frame sizes and with standard stroke lengths from 100 to 800mm in 100mm steps depending on size. The cylinders offer a choice of lead screw or ball screw drives, allowing designers to use the optimum positioning technology for their particular application. The lead screw variants can handle up to 1m/s2 acceleration and offer a repetition accuracy of ±0.07mm. The ball screw variants, which offer a choice of two different spindle pitches with efficiencies of up to 95%, can accommodate up to 6m/s2 and have a very high repetition accuracy of ±0.02mm. Depending upon the cylinder size and spindle, DNCE series cylinders can achieve feed velocities of up to 1000mm/s and feed forces as high as 2000N.
