 trials to assess the proposed solution. “We had to process a highly tempered V2A steel (a Cr-Ni rustproof grade) over a large diameter range for a medical- engineering customer,” reports Florian Winhard, sawmill departmental manager at Werner Weitner. “With the existing machines, cutting times were as long as 15 min., which we felt was an unsatis-
“A major advantage for us is that we can switch between carbide and cheaper high-strength-steel blades at any time," says Winhard.
factory outcome.”

An innovative feed system, which can be adjusted steplessly and with high pre- cision by means of two ball-screw spindles, each with a servo drive, ensures optimum performance. The KastoWin Pro AC 5.6 also has a retraction unit on each side for lifting the band from the surface when the saw head moves back. This makes for particularly efficient, exact sawing
“As a result of the reduced cutting times,” concludes Winhard, “the sawing process is considerably more efficient and we can process more orders in the same time.”

with minimal tool wear, according to Kasto officials
This fully automatic bandsaw is designed for varied applications, and has been opti- mized for use with bimetallic and carbide blades. In tests for Werner Weitner, the bandsaw achieved maximum cutting times of 7 to 8 min., half as long as with Werner Weitner’s existing equipment.
The bandsaw’s cutting range: 560 mm, with the smallest cutable dimensions measuring 25 by 25 mm. Werner Weitner uses the saw mainly for material diameters of 100 to 350 mm. The EasyControl saw controller reduces idle times in automatic operation for maximum cutting perform- ance. All parameters can be optimized to match the type of blade being used. Orders are input by means of a display, and the material to be cut is placed man- ually or by means of an overhead crane on a roller track, which feeds it to the machine. When finished, the cut pieces are removed by hand and transported by forklift truck for further machining.
The saw has been in operation at Werner Weitner since March 2017.
