Description
Technical field
The utility model relates to cutting element processing technique fields, and in particular to a kind of novel artificial tooth cutting element.
Background technique
Artificial tooth be exactly it has often been said that " artificial tooth ".Just as " artificial leg ", " artificial limb " are known as " artifucial limb ", the meaning of " artificial tooth "
Think just to refer to the tooth for people's class " obligation " to the greatest extent.It is medically repair latter made to the part or all of absence of tooth of maxillary and mandibular teeth
The general name of complex.Artificial tooth, which is divided into, can pluck and fix two kinds.Fixed denture (being commonly called as " fixed denture ") is cannot to be taken by patient oneself
It wears, and removable denture (being commonly called as " detachable dental prostheses ") can easily be taken by patient and be worn.The tooth of the mankind is although hard, but by
In irrecoverability, abrasion is huge, and the market demand is vigorous, is suitble to the production of the artificial tooth of oral cavity chewing and processing technology increasingly strong
Greatly, the existing external cutting element introduced is the consumptive material class apparatus of surgeon dentist, is a very tiny steel needle, this root needle
It is made of syringe needle and needle handle, can be inserted on high low speed mobile phone and use, help operates skilled worker and opens artificial tooth hole, and artificial tooth profile of polishing is repaired
Tooth etc..
The maximum feature of general Teeth-cutting tool is hardness height, and the sword tooth designed is very sharp, and cutting efficiency is very high.
For high speed dental cutting element when skilled worker is used for dental mill, different from the grinding of diamond dust, high speed dental cutting element is in work
It is not the part that abrades tooth and need to remove when making, is the dental tissue that cutting needs to remove, the bright and clean nothing of the dental surface cut
Scratch.The hardness of high-speed cutting tool is significantly larger than the hardness of tooth, and the sword tooth that works at high temperature is indeformable, with durable excellent
Different characteristic.
The cutting element of artificial tooth generally divides two kinds, first is that welding, first is that integral manufacturing.The skiver that welding is produced
Having working portion is alloy steel, and neck and shank are ordinary steels, the disadvantage is that being turned around using the disconnection of Shi Yicong weld；Add
Concentricity deviates when work makes, and there are slight swing vibration, high speed handpiece bearing easy to damage in when use；Advantage is production cost
It is low.Cutting element working portion, neck and the shank that global approach is produced are one, and concentricity does not shift when processing and fabricating,
Without swing, the service life of effective extending cell phone when use；Integral manufacturing does not have weld seam not have to snap the phenomenon that turning around, and uses
Safety.
In actual use, although the connection size of the mobile phone of installation cutting element is unified standard, mobile phone itself
Size it is not fully identical, different appearance, depth of profile influence the use of operator.Meanwhile the cutting of cutting element
Tooth height can also impact the actual use of cutting element, not occur a kind of outer dimension in the prior art properly simultaneously
And there is the high-speed cutting tool of suitable cutting tooth height, while to meet the requirement of cutting sharpness and durability, therefore, urgently
Exploitation innovation need to be carried out to it, to meet the urgent need in artificial tooth production and processing.
Summary of the invention
For the prior art there are above-mentioned technical problem, the utility model provides a kind of artificial tooth cutting element.
To achieve the above object, the utility model the following technical schemes are provided:
A kind of artificial tooth cutting element, including head and shank, the head is cylindrical, and the connecting pin of the shank is in circle
The other end of platform shape, the shank is cylindrical, and one end of the shank truncated cone-shaped is connected with the bottom surface on the head；The head
Portion, shank and cutting element are whole on same central axes；It is characterized in that, on the outer circumference surface on the head in the shape of a spiral
Several cutting teeths are vertically evenly distributed with, the cutting teeth and the outer diameter face on the head are tangent, and the vertex of the cutting teeth is high
The outer diameter face 0.24-0.37mm on the head out, the basal diameter on the head are 2-3.5mm, a height of 5-9mm on head；Institute
It states and has been spirally distributed several small cutting teeths, small cutting teeth and Cutter head section on the cutting teeth outer circumference surface of cutting element
End face distance be 1.3-1.65mm；The surface roughness Ra of the artificial tooth cutting element is 0.3-0.7, the artificial tooth cutting
Each end face squareness of tool is less than 0.05, and on the basis of central axes, axis, circular runout are less than the artificial tooth cutting element
0.05。
Further, the central axes of shank truncated cone-shaped one end and the angle of its frustum cone side are 5-10 °.
Further, the central axes of shank truncated cone-shaped one end and the angle of its frustum cone side are 8 °.
Further, the small cutting teeth tooth depth 0.02-0.05mm of the head outer circumference surface Spiral distribution.
Further, the artificial tooth cutting element is process using wolfram steel integral type；Or the head of the cutting element
Portion, shank are welded by wolfram steel processing again respectively.
Further, the vertical cutting teeth number of teeth of the artificial tooth cutting element helical form is 6 or 8 or 10.
Compared with prior art, the utility model has the advantage that
The cutting element of the utility model is by adjusting being arranged cutting teeth quantity appropriate and its depth and ring cutting is small cuts
The best durability of cutting element, but also tool had not only may be implemented using the cutting teeth cutting head of this moulding in the distribution for cutting tooth
There is difficulty of processing appropriate, realizes the balance of using effect and processing cost；
The artificial tooth cutting element of the application can be made of overall processing, and machining accuracy is high, and quality is high；It can also use
Split type to be processed into, processing cost is low, facilitates marketing.
