Top slitter blades

Top slitter bladesPowdered metal alloys stand better wear and corrosion than traditional tool steels. They also provide better dimensional accuracy than blades manufactured with traditional methods. The edges of powdered metal blades can be polished to substantially better surface roughness values. Normal grinding angles are 45° for paper and board. The diameter, thickness and other dimensions need to be manufactured according to OEM specifications.
