Advantages
1. Handle heavy shearing force and Outstanding dimensional accuracy.
2. Imported grinding and polishing machines ensure blade precision of ±0.001mm.
3. Clean cutting edges thanks to the low co-efficient of friction
4.New material HMY, perfectly shear 3-16mm high strength steel coils at the same time.

Product Features
The circular metal slitter blade is the most important link in slitter tool apron. The main problems customers encounter during use are the poor abrasion and edge crack in blade. Senda slitter blades have the following features, therefore reducing the blade sharpening frequency.
1. The blades of Senda are made of high quality raw materials and manufactured by forging and advanced vacuum heat treatment technology, which have high hardness and stability, and the abrasion resistance is remarkably improved.
2. The blade surface is processed with precision surface grinder and special grinding technology. After strict quality test, all finished products are guaranteed with a flatness of within 0.0003mm, a thickness tolerance of ±0.001mm, and a concentricity of within 0.02.
