Grinding treatment process titanium and titanium plates

Grinding treatment process titanium and titanium alloys are divided into : mechanical polishing , ultrasonic grinding, mechanical composite electrolytic polishing , grinding barrels .
A mechanical polishing : high chemical reactivity of titanium , low thermal conductivity, viscous medical titanium plates, abrasive grinding machinery ratio is low, and easy to react abrasives , not for ordinary abrasive grinding and polishing of titanium , preferably good thermal conductivity superhard abrasives, such as diamond , cubic boron nitride , polishing line speed is generally 900 ~ 1800m/min appropriate, otherwise , the titanium surface grinding burns easily and micro- cracks .
Two ultrasonic grinding : by ultrasonic vibrations , so that the surface to be polished and the abrasive grinding between the polished surface and the relative movement is to achieve grinding and polishing purposes. The advantage is that the polishing tool than the conventional rotary groove portion becomes easier to nest and narrow , but also a large grinding effect is not satisfactory castings .
3 Electrochemical Mechanical grinding : the use of conductive abrasive , electrolyte and a voltage is applied between the grinding and polishing the surface , the joint action by mechanical and electrochemical polishing , reducing the surface roughness to improve the surface gloss. The electrolyte was 0.9NaCl, voltage is 5V, speed 3000rpm/min, this method can only be grinding plane , polishing complex denture is still in the research stage.
4 barrels of grinding : the use of centrifugal barrel polishing generated revolution and rotation , so that the barrel of the denture and abrasive friction relative movement serve to reduce the surface roughness of the grinding purposes. Polishing automation,titanium strip high efficiency, but can only reduce the surface roughness to improve the surface gloss, poor precision grinding , deburring available denture fine and coarse grinding and before polishing .
