Description
Technical field
This utility model relates to dental sewing machine needle, particularly relates to a kind of ceramic-metallic dental sewing machine needle.
Background technology
Dental sewing machine needle is stomatologist's clinical treatment grinding drill tooth, and department of stomatology technician polishes and repairs artificial tooth reparation
The throw that body uses.What Dentist used at present mostly is corundum car pin and wolfram steel car pin, these metals
The car pin made all has metal-like, often brings certain uneasy sensation to people, especially for child, order
The apparatus plus metal-like is experienced in the treatment that people is unhappy so that the dental treatment of child is cumbersome.
Existing dental sewing machine needle is welded by the portion of working and shank and constitutes, and work in-process occurs that any error all will make
Beating easily occurs in the car pin obtaining high speed rotating, and causes grinding face rough.
Further, along with the development of society, people are more and more higher, so the most more coming to the prescription of life
More pay close attention to oral health.Existing dental sewing machine needle does not more meet the requirement of people.
Summary of the invention
This utility model is intended to overcome the defect of prior art, it is provided that a kind of bulk metal ceramic dental car pin.This
Utility model hardness is higher, and wearability is good, and the product glossiness processed is higher, good toughness, and the life-span is longer.
Shortening the operating time, patient pain feels and substantially alleviating.
In order to solve above-mentioned technical problem, a kind of bulk metal ceramic dental car pin, this dental sewing machine needle is monoblock type
Cermet material is made；Including blade and shank；Described blade has right spiral, and anterior angle is negative 10 degree,
Relief angle 35 degree.
Described bulk metal ceramic dental car pin, shank designs according to the dental handpiece that this dental sewing machine needle is supporting.
This utility model is used for breaking tank mainly for oral cavity doctor and opens marrow, takes off marrow top and uses this utility model hardness higher,
Wearability is good, and the product glossiness processed is higher, good toughness, and the life-span is longer.Car pin knife edge angular uses
Optimize design, make cutting tooth body more steady, sharper, more rapid.Shortening the operating time, patient pain feels
Substantially alleviate.This utility model uses monoblock type to manufacture no-welding-seam, and the higher nothing of product concentricity is beated, sword tooth essence
Carefully, it is ensured that the surface smoothness after cutting is preferable.
Dental sewing machine needle is at patient's mouth transluminal operation, and this utility model wearability is good, and life-span length just shortens patient
Doctor's time.The car wire surface fineness that additionally cermet material processes is higher, is of value to cleaning and sterilization.
Ensure that doctors and patients are healthy, stopped cross infection.
