Forstner STRAIGHT Cut to Length Line

FORSTNER STRAIGHT slit and cut to length machine - CIDAN Machinery Americas

5 Slitting Knives & cap-lock design

On the Forstner KA6-110 slit and cut-to-length lines, 5 Sets of slitting knives come standard. The shafts are made of polished tool steel and the slitting blades hardened with a Rc45 hardness. The tolerance between the shaft and blades is less that .0005” (.01mm), creating a smooth and easy-to-move positioning of the slitting blades anywhere on the shaft.

The cap-lock design consists of a half moon mild steel that presses onto the shaft by an allen head screw. Because the cap-lock is softer than the shaft, there’s no need to worry about “scoring” the shaft like other designs tend to over time.

The knives have a two side cutting surface, so you can alternate sides and take tension out of narrow slits. The machines come standard with a red with sliver letting on the scale for ease of reading the position of the top blade.

Sensitive Material Mode

Not only is the coil-selector automatically controlled, but also the adjustment of the upper straightening shafts.

Whenever a new coil is selected, the upper straightening shafts will be adjusted into a new position to ensure the straightening quality.

A special sensitive material operating mode prevents start-stop-lines by the upper straightening shafts and increases the quality of the coil-line enormously. Even a single sheet can be produced without coil-set or marking of the material by the automatically adjusted upper shafts.

6 Straightening Rollers

With the 6-roller straightener you can create mark-free, flat sheets. The upper straightening rollers are automatically positioned in front of the sheet and open before standstill to avoid stopping marks.

The straightener has a motor and one pair of infeed rollers, 6 straightening shafts . 110 mm and one pair of out-feed rollers . 70 mm. The upper straightening shafts are also programmable.
