Cermet blades not only need to have high hardness and high toughness as the base material, but also strictly implement relevant quality standards in the subsequent production processes of double-end surface grinding, slot grinding and edge passivation, so as to produce qualified and high-quality products. product.
We all know that the accuracy level of the blade can be known from the model of the ISO blade, so today we will first introduce the content related to the dimensional accuracy of the ISO turning blade.
For example, the model of the above blade is TPGH110304L10PK C3
The third letter G stands for precision, which is a grinding-level precision boring insert.
