A kind of separate type drill bit for widget punching and crisp material reaming
Technical field
It is specifically a kind of for widget punching and crisp material reaming the present invention relates to a kind of drill bit of engraving machine
Separate type drill bit.
Background technique
Widget is in punching, since lighter weight is easy that drill bit is followed to rotate, even carved on widget
When the lower hole of required precision, it is still desirable to which fixture clamps component, although widget small volume, is clamped with fixture
This process still can not simplify, therefore waste time, and make troubles to operator.
Crisp matter crystalline material is in artificial engraving, since crystalline material is cell configuration, easily basis during engraving
Its cell configuration type and there is accidental damage;Such as mica mutability flakiness, calcite are easy to crack at small rhombohedron.It damages
Basic reason be that and immediate cause is because drill bit makes crystalline substance to the pressure and frictional force of crystalline material caused by this body structure of crystal
Internal portion generates local internal stress, eventually leads to its damage.
Summary of the invention
For in the prior art the technical issues of, the present invention provides one kind for widget punching and crisp material reaming
Separate type drill bit, drill bit is made into multilayer, and the drill bit of adjacent layer is oppositely oriented, when to small part vertical drilling, drill bit
