[How to choose carbide bit?]
Release date:[2022/10/9] Is reading[294]次

At present, the use of cemented carbide drill in mechanical processing and manufacturing accounts for about 1/5 of the total amount of processing. In addition, cemented carbide bit has high hardness, strength, wear resistance and corrosion resistance, which is favored by processing enterprises. Today, we will talk about: how to choose carbide drill? What are the types of cemented carbide drills?

How to choose cemented carbide drill?

Carbide bit selection is based on the use of the scenario to choose, Nono to give you a common use of the scenario.

1, the use of advanced processing center

A solid cemented carbide bit is selected. The bit is made of fine-grained cemented carbide material and is coated to extend its service life. The specially designed geometric edge enables the bit to be self-centered for good chip control and removal when drilling most workpiece materials.

2. Use on lathes and other rotary machining machines

Select carbide indexable blade bits, which have a wide range of machining aperients, ranging from 2D to 5D(D is the aperture).

3, machining center, CNC lathe or other high rigidity, high speed machine tools.

Choose either a welded carbide bit or a replaceable carbide crown bit, in which a carbide crown is solidly welded to a steel drill body or a combination of a steel drill body and a replaceable integral carbide crown. Using self-centering geometric edge, cutting force is small, most of the workpiece materials can achieve good chip control, processed hole surface finish, dimensional accuracy and positioning accuracy are very high, do not need to carry on the subsequent finishing.

What are the types of cemented carbide drills?

Although there are many carbide bits, there are actually only four basic types: monolithic carbide bits, carbide indexable blade bits, welded carbide bits, and replaceable carbide crown bits.
