Abstract
The utility model discloses a cutter for perforating touch screen glass, which includes a clamping handle, wherein the clamping handle is connected with a cutter body; the cutter body includes a cylindrical cutter body and a circular arc-shaped tool bit; and the external surface of the cutter body is plated with a layer of diamond grain of sand. According to the utility model, when the cutter body plated with a diamond sand layer is used for perforating the touch screen glass, grinding efficiency, material removal ratio and processing accuracy are high, and edge breakage amount is low; through the matching of the circular arc-shaped tool bit, circular arc-shaped bevel edges and the size of the cutter body, contact area of the tool bit with the glass can be enlarged and torque during hole perforating can be reduced, so that the service life of the cutter can be prolonged, and processing cost of the touch screen glass can be reduced.
Description
Technical field
The utility model relates to the glass processing apparatus field, relates in particular to a kind of cutter for the processing of touch-screen glass drilling.
Background technology
Appearance along with further reduction, the especially i Phone of the continuous development of touch technology and cost has started a ripple contact panel upsurge especially in the whole world.The high-efficiency high-accuracy processing of touch-screen glass has become the focus that numerous enterprises is paid close attention to.Traditional touch-screen glass drilling processing is carried out at the machine drilling lathe by using inserted drill, and water, light oil or turpentine wet goods are cooled off.But, use this method processing touch-screen glass to have that mismachining tolerance is big, work efficiency is low and the high deficiency of labour intensity, especially bore mill at single face and be worked into the moment that glass penetrates soon, glass very easily produces " chip " phenomenon, form shelly limit defective of falling, cause stress concentration, intensity reduces, to cause glass breakage.
The utility model content
The purpose of this utility model is to collapse the limit amount greatly for solving when the use inserted drill is processed touch-screen glass, and work efficiency is low, the shortcoming that working accuracy is low, thus a kind of cutter for the processing of touch-screen glass drilling is provided.
For achieving the above object, the utility model is by the following technical solutions: a kind of cutter for the processing of touch-screen glass drilling, comprise a grip shank, described grip shank is connected with a cutter hub, described cutter hub comprises the cylinder shape blade and is the cutter head of arc surface that the outside surface of described cutter hub is coated with one deck diamond grit.
Specifically, the length of described cutter hub (2) be thickness of glass 1-3 doubly.
Specifically, the particle diameter of described diamond grit is the 320-1200 order.
Specifically, described grip shank is cylinder shape, and the diameter of described grip shank is d
1, 3mm≤d
1≤ 10mm, the length of this grip shank is L
1, 20mm＜L
1＜80mm.
Preferably, the diameter of described grip shank is 6mm.
Preferably, the diameter of described grip shank is 10mm.
Preferred version is that the diameter of described cutter hub is d
2, 0＜d
2≤ 1.5mm, the radius of described cutter head are 1.2d
2-1.5d
2
Preferred version is, described cutter head and blade junction are provided with certain circular arc chamfering, and the radius of described circular arc chamfering is 0.2d
2-0.5d
2
Compared with prior art, the beneficial effects of the utility model are: the utility model is coated with the diamond layer of sand by use cutter hub is holed to touch-screen glass and is added man-hour, grinding efficiency and material removing rate height, and it is low and working accuracy is high to collapse the limit amount; Cutter head and the circular arc chamfering of the utility model by being arc surface, and the cooperation of cutter hub size, the work-ing life that thereby the contact surface of cutter head and glass and the moment of minimizing when reaming improve cutter in the time of can increasing boring, thereby the tooling cost of reduction touch-screen glass.
Description of drawings
Fig. 1 is the diagrammatic cross-section of a kind of cutter for touch-screen glass drilling processing of the utility model.
Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation.
Embodiment
With reference to Fig. 1, a kind of cutter for the processing of touch-screen glass drilling that the utility model provides, comprise a grip shank 1, a cutter hub 2 and one deck diamond grit, it is the touch-screen glass of 0.7mm that the cutter in the present embodiment is used for processing thickness, and the aperture in hole to be processed is 1.2mm.The cutter length overall of present embodiment is 45mm, and grip shank 1 is cylinder shape, and the length of grip shank 1 is 35mm, and diameter is 6mm.(in other embodiments, the length of grip shank 1 does not influence the effect of the invention in the scope of 20-80mm; The diameter of grip shank 1 is in the scope of 3-10mm, and especially the diameter of grip shank 1 is 6mm, does not influence the effect of the invention.) end of grip shank 1 is connected with an end of cutter hub 2 and one-body molded.Described cutter hub 2 comprises the blade 22 that is cylinder shape and the cutter head 21 that is arc surface, be coated with one deck diamond grit 3 on the cutter hub 2, the particle diameter of diamond grit is 450 orders (particle diameter of diamond grit 3 can in 320-1200 purpose scope) in other embodiments.The length of cutter hub is 1.6mm, and wherein the diameter of blade 22 is 1mm, is guaranteeing that cutter hub 2 can penetrate the length that as far as possible reduces cutter hub 2 under the condition of the touch-screen glass moment when reducing in reaming, improves the work-ing life of cutter, thereby cuts down finished cost.(in other embodiments, the length of diamond cutter hub 2 and diameter determine that according to the thickness of touch-screen glass and the size in aperture to be processed the length of cutter hub 2 is 1-3 times of touch-screen thickness of glass respectively, and the diameter of cutter hub 2 is less than the aperture in hole to be processed.) cutter head 21 is an arc surface, the radius of cutter head 21 is 1.5mm, is 1.5 times of blade 22 diameters, with increase cutter hub 2 when the boring with the contact area of touch-screen glass, raising cutter intensity.(in other embodiments, the radius of cutter head 21 does not influence the effect of the invention in the scope of 1.2-1.5mm).Cutter head 21 is provided with circular arc chamfering 4 with the junction of blade 22, the radius of circular arc chamfering 4 be 0.3mm(in other embodiments, the radius of circular arc chamfering 4 does not influence the effect of the invention in the scope of 0.2-0.5mm).
