VARIAX is a generic name for high performance, high-speed press feeds and related products and systems. With a goal to meet different requirements in the press industry, we combined the latest know-how with an innovative product concept based on Sankyo’s unique cam technology. These feeds use our roller gear cam in the drive to create the world’s fastest feeds from Sankyo’s original motion curve and drive mechanism. In addition, with their excellent operability and user-friendliness, including easy parameter adjustments such as feed length, material thickness, grip force and roll...

VG series Feed with a soft touch. Reliable, high-speed gripper gives excellant results. This unit feeds materials by gripping them. The combination of four cam mechanisms provides high speed, high precision, and high reliability. Unlike roll feeders that feed materials by rotating the rollers, a gripper feed uses the coefficient of friction to grip materials. Therefore, a gripper feed makes it possible to feeding materials with different shapes and also soft materials. It will not create pressure scars or flaws on materials, feeds in fine increments if desired and can feed at super-high...

VGX series New type grip feed with adjustable release timing using a dial. To make adjustments without tools, to make fine adjustments during operation, to supply material at creep speeds, the new cam-driven grip feed is exactly what you want. It was developed from the results and experience we have established to improve work safety and operate at high speed. In addition to the excellent features (high-speed, high-precision feeding, and hard to scare materials) of the VG series, this series lets you adjust for material thickness, feed length, and release timing without needing any tools....

V series Cam type roll feed for high-speed and high-precision. This is a high-performance cam type variable roll feed that uses fan-shaped roller segment and four cams. Its feeding precision, excellant operability and workability are widely respected. This feed employs unique and new technologies such as a roller drive on both edges, a parallel level adjustment function between the roller and the clamper, and an absolute digital counter that displays the feed length precisely. Even though more than 30 years have passed since this model was developed, it is still in wide use with presses...

VSC /VLC series Producing the ideal material loop. Sankyo developed the NC loop controller in order to create the ideal loop shapes required by the feeding device, using servo technology. This VLC sets up optimum feeding by forming ideal loops in the space allowed, taking advantage of the spring characteristics of materials and stabilizing the loop using a sensor and servo control. The VLC has excellent handling characteristics in that it does not scratch, kink or dent material and can improve both quality and productivity. Employs a high-resolution high-torque servo motor drive. Eliminates...

Drive units V.S.D. (Variax Servo Drive system) The servo drive system is excellent for synchronized performance. VSD Variax Servo Drive The VSD (Variax Servo Drive) was developed specifically to drive cam feed units with servomotors. In order to achieve compliance with the start/stop characteristics of a press, our proprietary, newly-developed controller was integrated into the system to offer excellent synchronized performance. And, since the feed timing and indexing angle can be easily changed, it is being installed on more and more Variax products. S.C.T. (Self-Compensating Tensioning...
