Wila New Standard Bottom Tools

WILA New Standard bottom tools

New Standard bottom tools can be used on all press brakes that have a clamping slot measuring 13.5 x 22 mm (W x H). OZU tools in the New Standard program with a working height of < 100 mm, have V openings with bending radii amounting to approximately 10% of the V opening. OZU bottom tools with a working height of 100 mm come with larger bending radii (approximately 20% of the V opening), which is particularly effective when bending foil covered materials. By using larger bending radii, the foil remains intact longer and marking on sensitive sheet materials is reduced.

A number of tools in the New Standard program are available in two working heights: 55 mm and 100 mm. The tools with a working height of 100 mm offer more bending freedom. In addition to tools for air bending, the program also includes tools for bottom bending. For the bottom bending tools, not only the bending radii but also the entire V-opening are CNC deephardened, because with bottom bending the sheet comes into contact with not only the bending radii (like in air bending), but also with the sides of the V-opening.

CNC-Deephardening

CNC-Deephardening is a hardening process developed by Wila specifically for use in press brake tooling. The specific properties of this process make it 'the' process to apply a superior functional hardening layer. Applying the hardened layer is very well controlled; the hardening depth can be influenced with great - consistent  - accuracy and no additional stresses are brought into the product. Based on many years of research and experience, we have determined that the bending radii of press brake tooling should at least be hardened to 54 HRc; this value can be fully guaranteed by using the CNC-Deephardening process. Compared to the other hardening processes like laser hardening, nitrating etc., CNC-Deephardening results in a product with a superior longevity.
