Abstract
The invention discloses a dentist's tungsten carbide grinding pin for repair grinding. The tungsten carbide grinding pin is made into a tooth grinding tool having central bores and used in dental industry. The tungsten carbide grinding pin comprises a handle and a pin body. The handle and the pin body are centrally provided with central bores enabling cooling liquid to be injected from the top end of the pin body to the bottom end of the pin body. The cooling liquid can be injected into the central bores for cooling, lubricating and chips removing during dental grinding. The pin body is a small-diameter tungsten carbide alloy rod tube having the central bore. The handle is tube of a stainless steel or other alloy metal. The diameter of the inner bore of the handle is equal to the outer diameter of the pin body. The pin body is inserted into the inner bore of the handle and is welded. The application of the tungsten carbide grinding pin in the dental industry is broadened, the applicable range of the tungsten carbide grinding pin is widened, and the tungsten carbide grinding pin is high in strength, good in rigidity, long in service life and low in processing cost.
Description
Technical field
The present invention relates to powder metallurgy manufacturing technology field, relate in particular to a kind of dentist and repair grinding tungsten carbide card grinding.
Background technology
In powder metallurgy manufacturing technology field, the card grinding be made up of powder carbide alloy is widely used in the mechanical punching finishing, printed circuit board (PCB) (PCB-PrintedCircuitBoard) machine drilling etc. of jade.Tungsten carbide card grinding carbide alloy card grinding is a kind of, and its construction features is card grinding is solid, and diameter is little, length is long, and the length dimension margin of tolerance is less and perpendicularity requires higher.
Although tungsten carbide card grinding carbide alloy card grinding is repaired at the mechanical punching of jade, printed circuit board (PCB) (PCB-PrintedCircuitBoard) machine drilling etc. obtains successfully, but seldom there is the record of repairing grinding sector application dentist, trace it to its cause, mainly because card grinding is solid bar, cause card grinding chip removal difficulty when dentist repairs grinding sector application, local temperature rise is too high, limits grinding industry repaired by tungsten carbide card grinding carbide alloy card grinding application dentist.
Summary of the invention
The object of the present invention is to provide a kind of dentist to repair grinding tungsten carbide card grinding, the defect of application in grinding industry do not repaired by the tungsten carbide card grinding to overcoming prior art dentist.
For achieving the above object, present invention employs following technical scheme:
A kind of dentist repairs grinding tungsten carbide card grinding, this tungsten carbide card grinding is used for the reparation grinding of dentist, comprise needle handle and needle body, the middle part of described needle handle and needle body is provided with the centre bore making liquid coolant inject from the top of needle body, gush out from the bottom of needle body, described tungsten carbide card grinding is as the instrument of grinding one's teeth in sleep made for tooth industry band centre bore, described centre bore can inject liquid coolant, for the cooling in dentist's grinding, lubrication and chip removal.
As the improvement to technique scheme, described needle body is the diamondite rod pipe of the band centre bore of thin diameter, described needle handle is rustless steel or other alloying metal pipe, the diameter of bore of described needle handle equals the external diameter of needle body, described needle body inserts in the endoporus of needle handle, coordinates with the endoporus small―gap suture of needle handle.
As the improvement to technique scheme, described tungsten carbide card grinding is welded by needle handle and needle body two parts.
As the improvement to technique scheme, the length of described needle body is 6 ㎜ ~ 150 ㎜, external diameter≤1.5 ㎜, center-hole diameter≤0.6 ㎜, and the diameter of described needle handle is 3.175 ㎜, the endoporus of described needle handle and the external diameter of needle body suitable.
As the improvement to technique scheme, the length that described needle body stretches into needle handle endoporus is 1 ~ 3 ㎜.
As the improvement to technique scheme, above-mentioned tungsten carbide card grinding is used for dentist and repairs grinding.
Compared with prior art, the beneficial effect acquired by the present invention is:
Dentist of the present invention repairs grinding tungsten carbide card grinding, for the reparation grinding of tooth, comprise needle handle and needle body, the middle part of described needle handle and needle body is provided with the centre bore making liquid coolant inject from the top of needle body, gush out from the bottom of needle body, described tungsten carbide card grinding is as the instrument of grinding one's teeth in sleep made for tooth industry band centre bore, described centre bore can inject liquid coolant, for the cooling in dentist's grinding, lubrication and chip removal.
This tungsten carbide card grinding is welded by needle handle and needle body two parts, diamondite rod pipe and needle handle are combined firmly, needle body is grinding part, make with diamondite rod pipe, intensity, rigidity during grinding can be ensured, ensure quality and the efficiency of processing, needle handle is non-grinding part, be made up of the rustless steel of low cost or other alloying metal pipe, thus reduce the manufacturing cost of tungsten carbide card grinding, axiality when two parts are fit is ensured by the cooperation of needle handle and needle body, and axiality is high.Centre bore is provided with in the middle part of needle body, when in use, liquid coolant can be passed into, the abrasive dust of tungsten carbide card grinding cutting head can be discharged by one, prevents the wearing and tearing certainly of needle body head, and improves grinding efficiency simultaneously, two realize the cooling to tungsten carbide card grinding, the temperature rise of tungsten carbide card grinding is declined, thus ensures tungsten carbide card grinding intensity, rigidity, ensure quality and the efficiency of processing.The micro-abrasive point of tungsten carbide directly can be slotted to make and be frustrated cutter or use diadust coating, to improve its wearability.
Dentist of the present invention repairs grinding tungsten carbide card grinding and can be widely used in dentist and repair grinding industry, open up grinding industry repaired by tungsten carbide card grinding application dentist, add the scope of application of tungsten carbide card grinding, its intensity is high, good rigidly, long service life, and processing cost is low.
