Description
Technical field
The utility model relates to a kind of frosted cutter field, is specifically related to a kind of ceramic-like cutting element being applicable to abrading glass ceramic-like materials.
Background technology
The treatment in field, current oral cavity and repair process more and more level off to the other Personalized service of chair, patient is to attractive in appearance, Wicresoft, efficient innovation of repairing the demand drive material market of therapeutic process, and the material of the other miniaturized system processing of a series of applicable chair such as glass ceramics, high-intensity resin is developed successively.Along with popularizing of digitlization impression technique in mouth, the simple dummy of some patients has not needed by the unified production of large-scale skilled worker's organisation of working, processing.Miniature digital process equipment directly can enter clinic completely, with the use of novel glass ceramics class material in the other processing carrying out dummy of the chair of patient, can work as due to it and carry out rapid shaping in face of patient and carry out personalized post processing, make patient be participated in the manufacturing process of oneself tooth in person.Reparation, personal experience efficiently makes patient be easy to accept this mode.For this change on market, in western section code system, lathe needs to expand its working ability, develops the corresponding function for this types of material, to meet the needs in market.
The material of glass ceramics class material is special, and be all or part of quartz (feldspar) class material in composition, material hardness is high, fragility is large.In present western section code lathe, the wolfram steel car pin of processing metal and pre-sintered zirconium oxide and milling mode all can not process this type of material.So be necessary that Application and Development is in the glass ceramics grinding technique of western section code lathe for the demand in market, comprise and select the structure of material shape database and the supporting lapping mode of western section code lathe from car pin.
Utility model content
The purpose of this utility model is to provide a kind of ceramic-like cutting element, and grinding vibration is little, is applicable to the ceramic-like cutting element of abrading glass ceramic-like materials.
The purpose of this utility model is achieved through the following technical solutions:
A kind of ceramic-like cutting element, comprise cutter hub, the shape of described cutter hub is shaft-like, and the side of described cutter hub is provided with cutter head, and described cutter head is divided into transition region and milling zone, and the lateral surface of described transition region and milling zone is equipped with frosted; Described transition region is arranged between cutter hub and milling zone, and the shape of described transition region is coniform or umbrella; The shape of described milling zone is shaft-like, and the outer end of described milling zone is provided with hemisphere face.
Further, the outside of described cutter head is provided with plated film, increases the service life of cutter head, reduces coefficient of friction simultaneously, reduces the amplitude of cutter head in process of lapping, thus cutter head amplitude can be avoided excessive, the situation of the glass ceramics that shatters class material; Described plated film is any one in titanium nitride coating, TiCN plated film, nitrogen titanium aluminium plated film or chromium nitride film plating.
Further, the length range of described milling zone is 10mm-12mm.
Further, the diameter range of described milling zone is 1.0mm-2.0mm.
Further, the order number scope of the frosted of described bit interface is 100 order-140 orders.
Further, described cutter head and cutter hub are structure as a whole, and the hardness of cutter is maximized, avoids occurring in process, the situation that cutter head is separated with cutter hub.
The beneficial effects of the utility model are: the utility model is by being provided with the milling zone of radius much smaller than cutter hub, realize high pulling torque and drive needle-like abrasive body, grinding vibration is little, can not cause the cracked of glass ceramics class material, be applicable to carry out retrofit to abrading glass ceramic-like materials.
