Abstract
A grinding wheel drill bit used for drilling a glass hole comprises a drillstock and a grinding wheel drill bit. One side of the grinding wheel drill bit is in a concaved shape and made of black silicon carbide of resinoid bond. A four-arrises drill bit is arranged in the middle of the grinding wheel drill bit, screw threads are arranged on the other end of the four-arrises drill bit, the screw threads penetrate through the grinding wheel drill bit and twist the grinding wheel drill bit on the drillstock, and the hole drilling face of the grinding wheel drill bit is in a concaved shape, wherein the grit designation of the grinding wheel is 20 # to 36 # and the hardness of the grinding wheel is H to K. The four-arrises drill bit is arranged in the inner portion of the grinding wheel drill bit, and the four-arrises drill bit can play a role of locating in a drilling process and guarantee cutting accuracy. The grinding wheel drill bit is easy to manufacture, and convenient to use, and can drill a hole from one side without edge breakage, and drilling efficiency is high.
Description
Technical field
The utility model relates to a kind of emery wheel drill bit, specifically a kind of emery wheel drill bit that bores glass orifice.
Background technology
Glass drill head is to be used for boring in the glass production processing or to get the instrument that core is used, it generally is metal material, the sintered glass drill bit is generally arranged, the drill bit of electroplating and the drill bit of electroforming, but price general charged is somewhat expensive, and the punching number also is a lot, but need to hole from the two sides, cumbersome, and the situation on limit can appear collapsing in glass.
Summary of the invention
In order to address the above problem, the utility model provides a kind of emery wheel drill bit of practical and convenient glass drilling.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of emery wheel drill bit that bores glass orifice, comprise drillstock and emery wheel drill bit, the one side of emery wheel drill bit is spill, for the black silicon carbide of resinoid bond is made, one or four rib drill bits are set in the centre of emery wheel drill bit, the other end of four rib drill bits is set to screw thread, and screw thread passes the emery wheel drill bit emery wheel drill bit is screwed on the drillstock, and the length of four rib drill bits is longer than the length of emery wheel drill bit.
Further improvement of the utility model is: the one side of emery wheel bit bore inwardly presents spill, and grinding wheel graininess is grain size number 20#--36#, and hardness is H-K.
The beneficial effects of the utility model are: the inside of emery wheel drill bit of the present utility model arranges one or four rib drill bits, plays the effect of location when drilling, guarantees the precision of cutting, the emery wheel drill bit is made simple, and is easy to use, can be from one side boring, do not collapse the limit, drilling efficiency is high.
Description of drawings
Fig. 1 is section of structure of the present utility model,
Fig. 2 is emery wheel drill bit single face concave structure synoptic diagram of the present utility model.
Fig. 3 is the vertical view of four rib drill bits of the present utility model.
Wherein: 1-drillstock, 2-emery wheel drill bit, 3-screw thread, 4-four rib drill bits.
Embodiment
In order to deepen that understanding of the present utility model is described in further detail the utility model below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, this practical protection domain is not consisted of to limit.
As Figure 1-3, the utility model is a kind of emery wheel drill bit that bores glass orifice, comprise drillstock 1 and emery wheel drill bit 2, the one side of described emery wheel drill bit 2 is spills, makes for the black silicon carbide of resinoid bond, and one or four rib drill bits 4 are set in the centre of described emery wheel drill bit 2, the other end of described four rib drill bits 4 is set to screw thread 3, described screw thread 3 passes described emery wheel drill bit 2 described emery wheel drill bit 2 is screwed on the described drillstock 1, and described grinding wheel graininess is grain size number 20#--36#, and hardness is H-K.The length of described four rib drill bits 4 is longer than the length of described emery wheel drill bit 2, during punching, first glass backing plate is padded, and feed is even, uses continuously cooling fluid, and cutting speed not too is evident as suitable with " rustling " sound about 100m/min.
The inside of emery wheel drill bit of the present utility model arranges one or four rib drill bits, plays the effect of location when drilling, guarantees the precision of cutting, and the emery wheel drill bit is made simple, and is easy to use, can not collapse the limit from one side boring, and drilling efficiency is high.
The utility model is simple in structure, and is easy to make, and drilling efficiency is high.
