There is better advantage and application in machine design, manufacture.With the extensive use of carbon fiber, it is compound consequently also to bring carbon fiber
Material is in processing and the problem of fit on.At this point, the shortcomings that carbon fibre composite, more highlights, become drilling,
The main problem source of assembly.Carbon fibre composite drilling when mainly overcome carbon fiber composite structure high intensity,
The problems such as high rigidity, poor thermal conductivity, anisotropy, interlaminar strength be low, therefore, during fibre reinforced composites drilling,
In addition to traditional metal materials drilling defect (scale error, deviation from circular from, location error and error of perpendicularity etc.), it is also embodied by point
Layer, entrance tearing are with burr, hole wall surface spike protein gene etc., and processing efficiency is not high.
The country is original to process drilling on carbon fiber board, and device to hole shoulder carries out chamfering, uses an ancient type of spoon as shown in Figure 1, using
Head bores a drilling, then as shown in Figure 2 to carry out chamfering using counterbit b device to hole shoulder, therefore entire two knives of process requirement carry out
Processing, processing method are hand pneumatic tool, such low efficiency and the drawbacks of be easy to appear size bad control；Existing technique
It is divided into two cutters to be that can guarantee that fillet surface precision is more preferable, and the cutting resistance processed twice is small, institute the reason of completion
With drill process before this using a reason of knife dual-purpose overall plan it is never that will cause fillet surface not straight, and
Cutting edge is easy tipping.
