Abstract
Glass drilling processing method, it relates to glass processing method.Its procedure of processing is: 1) select the drill bit of subdrilling, makes the bit diameter bit diameter less than rear brill of subdrilling；2) the drill bit cutting edge bored afterwards is at an angle, makes internal diameter height external diameter low, it is ensured that cutting edge internal diameter first contacts glass；3) the bit bore degree of depth of subdrilling is slightly larger than collapsing the Breadth Maximum that limit requires；4) the bit bore degree of depth bored afterwards is equal to thickness of glass；The present invention uses first drill bit and the rear drill bit junction aperture less than required processing, i.e. leave allowance and implement Boring, make hole wall processing be completed by rear drill bit one, thus eliminate two drill bits and join the problems brought, it is ensured that hole wall uniform and smooth.
Description
Technical field:
The present invention relates to glass processing method, be specifically related to a kind of glass drilling processing method.
Background technology:
Glass belongs to crisp and hard material, generally uses diamond bit the cooling water that presses to carry out
Boring.A kind of method is: take single the unidirectional boring of drill bit, drill bit in drilling process, sword
Thickness of glass under Kou is the most thinning, the cutting edge drilling pressure applied and rushing that cooling water applies
Under power effect, when glass thin to a certain extent time, produce bursting apart property run through, cause bigger collapsing
Limit.The method of another kind of improvement is: take double drill bits priority boring, the drill bits of subdrilling in opposite directions
Completing the more than half of thickness, the rear drill bit bored, after drilling glass, continues to move ahead a bit of, repairs
Switching phase collapse limit, bursting apart property is run through the centre having transferred to thickness of glass direction by this method
Position, has effectively evaded and has collapsed the problem that limit produces at end face.Use this improved method, still
Cannot avoid collapsing the problem that limit is developed to inside glass from hole wall at intersection.Further, bored
Hole machine assembly precision and the deviation of beating of two main shafts, the precision of two bit diameters and beat partially
The abrasion of difference, drill bit cause the impact of the factors such as diameter dimension deviation, cause handing-over mouth dislocation, real
It is difficult on border obtain uniform and smooth hole wall, affects the precision in hole and attractive in appearance.
Summary of the invention:
It is an object of the invention to provide glass drilling processing method, its technique is simple, glass after processing
Glass end face and hole wall are without collapsing limit, and hole wall is uniform and smooth,
In order to solve the problem existing for background technology, the present invention uses following procedure of processing:
1) select the drill bit of subdrilling, make the bit diameter bit diameter less than rear brill of subdrilling；
2) the drill bit cutting edge bored afterwards is at an angle, makes internal diameter height external diameter low, it is ensured that cutting edge internal diameter
First contact glass；
3) the bit bore degree of depth of subdrilling is slightly larger than collapsing the Breadth Maximum that limit requires；
4) the bit bore degree of depth bored afterwards is equal to thickness of glass.
After in described procedure of processing 1, the internal diameter ＜ subdrilling bit diameter≤hole of drill bit is straight
Footpath-collapse limit Breadth Maximum requirement, when collapsing hem width degree more than bit wall thickness, selects wall thickness value.
Described subdrilling bit diameter is less than rear drill bit diameter, and the annular groove external diameter of processing is less than institute
Requiring the aperture of processing, after defining one, drill bit collapses the partition grooves on limit when drilling.
Described first drill bit and rear drill bit junction, less than the aperture of required processing, are i.e. stayed
There is allowance to implement Boring, make hole wall processing be completed by rear drill bit one.
The drill bit cutting edge bored after in described step 2 with axially in 45～60 ° of angles, afterwards brills
Head is first drilled glass by internal diameter, and now, cooling hydraulic impact is released, outside so reducing
Footpath not yet completes the pressure of processing part, reduces and collapses hem width degree.
The present invention uses first drill bit and the rear drill bit junction aperture less than required processing,
I.e. leave allowance and implement Boring, make hole wall processing be completed by rear drill bit one, from
And eliminate two drill bits and join the problems brought, it is ensured that hole wall uniform and smooth.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention:
Referring to Fig. 1, this detailed description of the invention following procedure of processing of employing: 1) select subdrilling
Drill bit, makes the bit diameter bit diameter less than rear brill of subdrilling；2) the drill bit cutting edge bored afterwards
At an angle, make internal diameter height external diameter low, it is ensured that cutting edge internal diameter first contacts glass；3) subdrilling
The bit bore degree of depth is slightly larger than collapsing the Breadth Maximum that limit requires；4) the bit bore degree of depth bored afterwards
Equal to thickness of glass.
This detailed description of the invention first drill bit of employing and rear drill bit junction add required by being less than
The aperture of work, i.e. leaves allowance and implements Boring, makes hole wall process by rear drill bit one
Prop up, thus eliminated two drill bits and join the problems brought, it is ensured that hole wall equal
Even smooth.
Embodiment 1: solar film plating battery glass drilling method
Solar film plating battery glass, thickness 3.2mm, aperture 20mm, due to needs tempering,
Need drill end surface chamfer 0.5 × 45 ° to eliminate stress, it is to avoid stress in toughening process
Concentrating the glass explosion that reason is brought, therefore boring is collapsed hem width degree maximum and be must not exceed 0.5mm,
Otherwise chamfering cannot eliminate and collapse to the greatest extent limit.
Use the vertical bores machine that glass horizontal is placed, rotating speed 2100 revs/min, rate of penetration
The 0.8mm/ second, inner-cooled Cooling Water.Select subdrilling bit diameter: 20-0.5=19.5mm；
Rear drill bit diameter 20mm, blade angle 60 °, bit wall thickness is 1mm.
Processing method is: by first drill bit (lower brill) punching (degree of depth maximum more than 0.5mm
Collapse hem width degree, it is determined as 0.6mm) → under bore reset → rear drill bit (upper bore) punching (stroke
3.2+0.1=3.3mm) → above bore reset → punched.
Referring to Fig. 1, when upper brill internal diameter drills glass, hydraulic pressure discharges, upper drill lip mouth outer radius
It is 1.177mm from glass lower surface distance, still has enough thickness, limit will not be collapsed.Afterwards,
What upper brill was implemented is bore hole effect, and allowance is 0.25mm, and whole hole wall is drilled into from above,
Hole wall is without the vestige that brings of handing-over, and hole wall is uniform and smooth, actual collapses limit ＜ 0.25mm.
