Carbon fibre composite product, so that the quality of whole aircraft.The crudy of connecting hole is directly connected to the assembling matter of aircraft
Amount and Aircraft life.Owing to carbon fibre composite is heterogeneous body and anisotropic, and the hardness of carbon fiber is the highest, thus multiple
The machining of condensation material is essentially different with metal material, therefore uses traditional drilling gold when composite drilling
The method belonged to will produce more problem.During drilling, any quality problems all can form the defect of product, causes part rejection.According to
Statistics, aircraft is when finally assembling, and drilling disqualification rate to account for more than the 60% of whole composite material parts scrappage.
During carbon fibre composite drilling, the size of axial force directly affects drilling quality, is to cause hole wall week
Enclosing layers of material, hole enters, outlet tears, the principal element of the significant deficiency such as burr.Use the high speed of mainshaft and low feeding
Speed is conducive to reducing axial force, but this otherwise lathe is proposed higher requirement, or working (machining) efficiency can be reduced.
During drilling, along with cutting depth increases, the non-thickness of cutting of material reduces, carbon fibre composite critical
Axial force declines the most therewith, when the axial force that drilling produces exceedes its axis critical force, the outlet side in hole is occurred layering
Deng manufacturing deficiency, exit remains the more fiber burr not cut off, and the crudy of incision position is relatively rough, has some fibre
It is exposed near bore edges, additionally, excessive axial force also results in the generation of outlet tearing defect.Generally, carbon fiber is combined
The veining defect of material can pass through file or elimination of reaming further, but, tear and lamination defect are even more serious, once
Occur, it is virtually impossible to repair.

Workpiece is fixed on fixture.
Described drill bit I is arranged for concentric with drill bit II.
Described main shaft I and main shaft II use the one in pneumatically or electrically main shaft.
This utility model is particularly suited for arbitrarily symmetrically or non-symmetrically structure and material are the work of carbon fibre composite
Part carries out drilling.
Perforating device of the present utility model provides the benefit that, this utility model avoids carbon fibre composite and punches out
Burr, the problem tearing and being layered occur at Kou.This utility model has been possible not only to the most symmetrically or non-symmetrically structure
Carbon fibre composite carries out the making of high-quality single hole, and is capable of the making of high-quality stepped hole.This utility model
Simple to operation, cost of manufacture is low, and production efficiency is high.
