Background technology
Dental high-speed cell phone is the professional tool that Hospitals at Present dental clinic is used, and dental high-speed cell phone is dental high-speed whirlpool
The abbreviation of mobile phone is taken turns, current application field is more and more extensive, except the department of stomatology, also internal medicine, orthopaedics, beauty and shaping industry
Use.Dental handpiece can be divided into major part according to the size of head（High pulling torque）, it is standard header, mini first three kinds.In Clinical practice
Selection it is also different, major part dental high-speed cell phone is applied in the more of standby tooth；The general doctors of standard header are selected as treatment
Instrument；It is mini it is first as be useful in children or women patient.Dental high-speed cell phone is using in high pressure air drives handset machine head
Miniature turbine rotation, secondary speed is up to the r/min of 30-50 ten thousand, and the cutting linear velocity of car pin is up to 15m/s.
Requirement to dental high-speed cell phone mainly includes：Because the turbine of 1, generation rotation is just mounted in head, thus it is right
The required precision of the head is strict；2nd, the anti-resorption design of head, whether be resistant to professional thermal cleaning, whether be resistant to 135 DEG C and go out
Bacterium；3rd, the surface treatment of mobile phone must have coating, be subjected to high-temperature sterilization and non-corrosive, be difficult to be infected with dirt, easily cleaning disappears
Poison.
Complex-shaped due to head, current dental high-speed cell phone head is all to be split into two parts, is passed through with brass
It is machined, then Combination Welding, last polished polishing, plating crome metal are made.The processing method is necessarily caused：1st, process
Cost is high；2nd, raw material are wasted；3rd, plating pollution environment；4th, precision is reduced after welding, and is also easy to produce noise；5th, brass uses process
In have the precipitation of lead；6th, electrodeposited coating is easy to fall off.
The content of the invention
