As an excellent alloy material, cemented carbide has a very important position in the field of industrial manufacturing and is known as "industrial teeth". Whether it is the production of tool materials such as turning tools, drills, and boring tools, or the processing of high-manganese steel, stainless steel, heat-resistant steel and other materials, cemented carbide is inseparable.
The main components of carbide point drill bits are: solid carbide drills, carbide indexable insert drills and replaceable-tip carbide point drill bits.
Reuse, can control the cost of processing. The carbide indexable insert drills have a variety of types, easy to change tools, and do not have the centering function. Replaceable cutter head carbide drills also have a centering function, with a complete range, high machining accuracy and efficiency, and the cutter head can also be reground.
Although cemented carbide has the advantages of wear resistance, corrosion resistance and high hardness, when the cemented carbide point drill bits is drilling, the torque of the workpiece is large, and the thermal expansion and contraction caused by the phenomenon can easily cause the drill to break in the hole. Avoid this?
1. When the strength of the drill bit is acceptable.Reduce the width of the chisel edge to avoid the wear of the drill bit by the axial force.
2. Different drill bits and cutting speeds should be selected for different materials.
3. When drilling materials with serious surface hardening.try to avoid friction on the cutting surface, and the drill bit will be worn out.
4. When cutting the workpiece material, pay attention to the use of cutting fluid, use it in time, and maintain lubrication.
5. The use of special high-performance alloy blades can reduce chipping and maintain good wear resistance.
