The formation of surface cracks at the bottom of the sipe

The contact surface formed by the blade and the sipe causes the uneven distribution of the black holes so that the welding cannot form a flat bond. The uneven distribution occurs so that the solder not only affects the strength of the weld and causes stress concentration, causing the blade to break. Therefore, the grinding contact surface of the boring blade should be clean and the appearance of the welding blade sipe.
The blade holder of the blade that needs to protrude is not more than 0.5mm to receive tensile force and breakage.
Three-edge cutter use

In addition to the main cutting edge on the circumferential surface, the three-edge milling cutter also has secondary cutting edges on both sides, thereby improving the cutting conditions, improving the cutting efficiency and reducing the surface roughness. It is mainly used for milling of stepped and grooved surfaces of medium hardness and strength metal materials. It can also be used for processing of non-metal materials. The ultra-hard material three-blade cutter is used for the milling of stepped and grooved surfaces of difficult-to-cut materials. Processing. It is mainly used to mill the groove of fixed value size, and can also mill general groove, step surface and side surface.
What is a three-edge cutter?

Three-blade cutter Abbreviated three-blade: All three edges have a back angle, sharp edges, and light cutting. Three-edge cutters are standard machine tools and are usually used on horizontal milling machines and are generally used for milling grooves and steps.
shape:
Its shape is like the “circular hole in the middle of the sesame cake” and its outer circle, and the two end faces near the outer circle have cutting edges (like a wide sawtooth) so it is called a three-sided edge. The main cutting edge of the three-edge milling cutter is distributed on the cylindrical surface of the milling cutter, and the minor cutting edge is distributed on both end faces. When used, the knife is installed on the arbor of the horizontal milling. Of course, it can also be installed on other machine tools. It is generally used for milling grooves and steps.
