Our country studies the history of metallic cutting is not long still, but after using the law of earning at producing practice when people, with respect to the action that can discover its are powerful, seminar of technology of production of international of no less than (does CIRP) consider to report middle finger gives: in? City of poisonous Hui of  of  of admire of mother of department of herd of poisonous Bu of closely question of dam take along sth to sb vasts  of caries of Yu of that Xing Liang carries?0 year, can raise one times almost: As a result of cutting tool structure and geometrical parameter improve, cutting tool durability, every other 10 years, raise 2 times almost. " current world is in information of science and technology to develop at full speed, new material applies generally at manufacturing times, how to use the basic theory that metallic cutting machines, go observation, analysis and the real problem in solving metallic cutting to machine, according to specific requirement parameter of geometry of material of choice cutting tool, cutting tool and cutting are used complete. Reach its to ask by craft reasonable choose cutting tool and design cutting tool, in order to improve metallic cutting beneficial result. The method of thread machining is very much, turning treatment whorl is one of the most commonly used methods. Improve screw cutting efficiency, shorten change knife and adjust the auxiliary time such as cutting tool, it is the target that people approach seeks. 2 kinds introduce to had compared mature thread machining cutting tool in producing practice below, communicate with the person of the same trade and discuss. Graph knife of silk of car of high speed of 1 ball bits pursues forming machine of 2 one knife places whorl to carry buckle a knife knife of silk of car of high speed of 1 ball bits pursues knife of silk of car of high speed of the 1 bits that it is a ball. Cutting tool characteristic: (Material of 1) razor blade is YT15 hard alloy, cutter hub is 45 steel; (Horn of 2) point of a knife is 59 ° 30, the horn after Zun Ren 5 ° 30, the horn after right blade 3 ° of 2 ° ～ ; (3) goes out to enhance edge radian to grind 0.

1 ～ 0.

2mm, 3 ° of 1 ° ～ lose edge; (4) is cut bits glomerate, with benefit safety, horn is 3 ° before, knife face tilts before for 0 ° 30. Working parameter: M24 of ～ of M20 of size range of pipe bent, v=30 ～ 34m/min. Use effect: One knife figuration, platoon bits is successful, cut bits glomerate, ra3 of whorl surface surface roughness.

2µm, safety is good with. Note: ? Dark be jealous of protects  ? of travel of children's hair of ぷ of Sun smile Quan.

5mm. Whorl of forming machine clip carries one sword of 2 60 ° the graph that buckle a knife 2 for one knife forming machine clip whorl is carried buckle a knife. Cutting tool characteristic: (1) cutter hub is 45 steel, quench hardness HRC45-50, bit is YT15; (Mill of 2) bit cypress has the part before 4 ° . Do not grind bits chamfer, borrow pressure piece on hard alloy breaks bits;(3) razor blade not via soldering, hold original property, service life is long, reduce loss; (4) uses a horizontal stroke to be pulled control fashion, place firm firm, make convenient, pressure have 110 ° horn and inclination of cutting tool blade quickly with the mask before cutting tool 4 ° , scrap is glomerate eduction, safety in operation. Working parameter: ? R=1 of pitch of  Zuo =613r/min.

5mm, one knife figuration. Use effect: ? ?-3 of π of A of Gou of poisonous to instruct of sew word astounded times, exterior surface roughness can amount to Ra1.

6µm, above. Note: ? Ρ of team of Xi of Wang of commonplace す ぷ lets? of Lei of  Gui Ji.

4 ～ 0.

5mm. Otherwise external diameter is squeezed big, do not cooperate to go up with nut.

3 last words are popularized in producing practice and use cutting tool new material, machine to place (do not grind again) the cutting dosage with angle of geometry of cutting tool of lathe tool, reasonable change, right choice, can raise cutting tool durability apparently, the treatment that improves spare parts appearance is shown character, economic grind a knife, change knife, installation, adjust wait for auxiliary time, raise labor substantially to manufacture efficiency, reduce manufacturing cost.
