The Kraftformer with the continuously  adjustable working strokes

The ECKOLD Kraftformer KF 340 is part of the medium-force Kraftformer range  with motor drive. Depending on the workpiece to be machined, the operator  can adjust the number of working strokes of the ECKOLD Kraftformer KF 340  to any value between 250 and 550 strokes per minute continuously. This op-  tion allows for optimised machining performance. Low speeds are particularly  suitable for shrinking, stretching and for straightening and precision finishing.  Thanks to the high stroke rate, the machine is also widely used for doming  (dishing) and planishing, boosting productivity. As is the case with all ECKOLD  Kraftformers, the KF 340 can be operated with various different tools and is  thus the perfect all-rounder for metal working, capable of machining steel  sheets of up to 3 mm in thickness!
