Description
Technical field
The present invention relates to mechanical equipment technical fields, specially the high-performance carbide rotary file towards difficult-to-machine metal
Knife.
Background technique
Machinery refers to the general name of machine and mechanism.Machinery is exactly that people can be helped to reduce work difficulty or labour-saving tool dress
It sets, as the article of chopsticks, broom and tweezers one kind can be said to machinery, they are simple and mechanical.And complicated machinery is just
It is to be made of the simple and mechanical of two or more.These more complicated machinery are usually called machine.From structure and fortune
From the viewpoint of dynamic, mechanism and machine and indistinction are loosely referred to as machinery.Machinery is derived from the Mechine and Latin of Greek
Machina, original refer to " cleverly design ", as general mechanic concept, can trace back to ancient Roman's period, primarily to
Difference and hand tools.Its " machinery " word of modern Chinese is that mechanism is English its (Mechanism) and machine (Machine)
General name.Mechanical feature has: machinery is a kind of combination of artificial component in kind.There is the opposite of determination between mechanical each section
Movement.Therefore machine energy converter tool energy or useful mechanical work is completed, it is the most basic concept in modern mechanical principle.
There are many fine and closely woven cutter tooth, bar shaped on file surface, the hand tools for file finishing workpiece.For to metal, timber,
Do micro processing in the surface layers such as leather.Greece's document is originated from about the record of file earliest in the world.B.C. 2000 according to records
Left and right Greece Crete civilization has invented bronze file, and earliest brass file is illustrated in B.C. ancient egypt human hair in 1300
Knife, and iron file has been invented in B.C. 700 years or so.Roman has made using infiltration before and after 1100 Christian eras are recorded in west
The file of carbon heat treatment technics, it is believed that ancient Chinese, in B.C. 200 years or so Qin Han dynasties, carburizing tech is just general
All over machined applied to file.File is demonstrated this saying by one to be unearthed for tomb of Han dynasty (B.C. 113 years) all over the city --- and it is " thin
Long shape, one end are damaged.A nearly half part for single side chops the topping for having transverse plane, and there are six teeth in 1 centimetre.Similar to 21
" the dent shape file " of beginning of the century, belongs to wood file type.Remaining partial-length is 20.4 centimetres, and width is 1 centimetre, and thickness is then
0.3-0.5 centimetres ".The application of file is very early, it has been found that most ancient file be B.C. 1500 or so Egyptian bronze
File processed.Modern file generally use carbon steel through rolling, forging, annealing, be ground, chop the processing of the processes such as tooth and quenching and
At.File is t12 steel, and hardness is up to 62~64 after surface hardening.
Carbide rotary tool knife is the essential tool of pincers worker mechanization, and purposes is very extensive, machinery, automobile,
The industrial departments such as ship, chemical industry, technique engraving use, and significant effect, carbide rotary tool knife many at present is all one
