Face stress is big, and low efficiency.In addition, the accurate grinding processing technology about carbon fibre composite plate, domestic and international rarely seen correlation
Report.
It therefore, is current machine with regard to how efficient grinding goes out the carbon fibre composite plate part of great surface quality
Tool processing technique field engineering problem urgently to be resolved.
Summary of the invention
To solve the above problems, the present invention provides a kind of carbon fibre composite plate grinding processing method, including it is following
Step:
The processing method uses vertical type numerically controlled machine, by applying cup type skive, to carbon fibre composite side
Shape planar surface carries out vertical end face corase grinding and fine grinding；
Step 1: the carbon fibre composite plate blank clamping being ready for is fixed on platen；
Step 2: by cooling tube to the comprehensive spray cooling liquid of workpiece work surface, surface impurity is washed away, is mentioned simultaneously
Preceding cooling down workpiece；
Step 3: vertical end face corase grinding is carried out to carbon fibre composite plate using cup type skive；
Step 4: after the completion of corase grinding, by adjusting grinding parameter, continue to refine；
Step 5: after fine grinding, cleaning drying, and its surface is detected with contact surface roughometer.
When corase grinding, the speed of mainshaft is 3000~5500rpm, and feed speed is 150~300mm/min, and emery wheel feed amount is
0.1~0.3mm.
When fine grinding, the speed of mainshaft is 5500~7500rpm, and feed speed is 50~200mm/min, and emery wheel feed amount is
0.01~0.05mm.
The clamping tooling can be common tiger's jaw fixture or vacuum chuck.
The cup type skive is composed of knife handle, cutter hub and bistrique three parts, wherein knife handle and cutter hub by
It is 120#~240# that the manufacture of common stainless steel material is manufactured by diamond into, diamond grit at, end face grinding head, and the mill
Head bottom face outer edge has one 30 °~45 ° of chamfering.
When the vertical end face corase grinding and fine grinding, cup type skive central axis and grinding workpiece surface are hung down
Directly, emery wheel grinding-head bottom face is contacted with grinding workpiece surface, and grinding wheel high speed rotation while moves in the horizontal direction, to grind off
Surface surplus.
The corase grinding and fine grinding tool path pattern is two-way round-trip form.
The beneficial effects of the present invention are:
Using carbon fibre composite plate grinding processing method provided by the present invention, by application by stainless steel and Buddha's warrior attendant
The cup type skive that stone is composed carries out two-way round-trip vertical end face high-speed grinding to workpiece made of carbon fiber composite,
Spray cooling liquid, the grinding mode simultaneously in grinding process, can effectively avoid tool wear, piece surface burn, surface
The problems such as stress is excessive, layering is torn and burr, processing technology is simple, and easy to operate, high in machining efficiency, processing quality stabilization can
It leans on.

Specific embodiment
Technical solution of the present invention is described further with reference to the accompanying drawing, but required protection scope does not limit to
In described:
The present invention provides a kind of carbon fibre composite plate grinding processing method, comprising the following steps:
Step 1: the carbon fibre composite square plate blank 1 that will be ready for is fixed by common 3 clamping of tiger's jaw fixture
In on platen 4；
Step 2: by cooling tube 5 to the comprehensive spray cooling liquid of 1 work surface of workpiece, surface impurity is washed away, simultaneously
The effect of cooling down workpiece 1 in advance can be played；
Step 3: the cup type skive 2 that by granularity be 240#, bottom end surface chamfer is 45 ° is mounted on R5030 and stands
On formula main shaft of numerical control machine tool, keep grinding wheel central axis vertical with 1 surface of carbon fibre composite plate, main shaft drives grinding wheel rotation,
It feeds down simultaneously, makes end surface of diamond grinding wheel cutting edge contact workpiece, then move grinding, while spray cooling liquid along the direction V,
By way of two-way feed, the corase grinding to carbon fibre composite plate 1 is completed.Speed of mainshaft n is when being wherein ground
