Abstract
The invention provides a forming method of a sapphire pipe, and belongs to the technical field of crystal processing and forming. The method comprises the following steps that a sapphire crystal without visible defects is fixedly arranged on a backing plate by an adhesive; the cured sapphire crystal is fixedly arranged on a workbench of a numerical control milling machine; the numerical control milling machine is started to drill a hole which has the same inner diameter as the sapphire pipe; a diamond drill pipe which has the same outer diameter as the sapphire pipe is replaced, and a zero point of an Z axis of a cutter of the numerical control milling machine is redetermined; the sapphire pipe is drilled with an outer circle which is concentric with the inner diameter of the sapphire pipe; the processed sapphire pipe is moved to a constant-temperature heating platform, the heating temperature is set to 380-400 DEG C, and the sapphire pipe is heated and insulated for more than 60 minutes; and the sapphire pipe is removed, and is naturally cooled at the room temperature. The method has the advantages that the defects of large positioning error of diamond single-line cutting sizes and poor concentricity of the sapphire pipe are overcome; meanwhile, the defect of unfavorable polishing of the inner wall of the hole due to a damage layer remained on the surface of the sapphire crystal caused by the laser drilling is overcome.
Description
Technical field
The invention belongs to crystal machine-shaping technical field, relate in particular to a kind of forming method of sapphire pipe.
Background technology
Because sapphire crystal has the characteristics such as hardness height, wear-resistant, high temperature resistant, acid-alkali-corrosive-resisting, and has good optical property, therefore, is widely used in various optical detecting instruments and various visual instrument window interface.
Sapphire pipe mainly adopts laser boring at present, then is cut to the size of requirement with the diamond single line.Its shortcoming is as follows: the laser boring meeting stays the damage layer on the sapphire crystal surface, be unfavorable for the polishing of hole inwall; The characteristics such as diamond single line cut lengths position error is large, and the sapphire pipe concentricity is not good.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of forming method of quick, easy, cost is low, scale error is little sapphire pipe.
Purpose of the present invention realizes by following technical proposals:
(1) will be fixed on the backing plate with glue without the sapphire crystal of visual defects;
(2) sapphire crystal that is cured is fixed on the CNC milling machine workbench;
(3) start CNC milling machine, bore the consistent hole of required sapphire pipe internal diameter;
(4) change the diamond drilling pipe conform to required sapphire pipe external diameter, redefine CNC milling machine cutter Z axis zero point;
(5) bore the concentric cylindrical of sapphire pipe internal diameter at sapphire crystal;
(6) sapphire pipe that processes is moved on the heated at constant temperature platform, it is 380 ~ 400 ℃ that heating-up temperature is set, and heats and is incubated more than 60 minutes;
(7) take off sapphire pipe, at room temperature naturally cooling.
Adopt the inventive method, it is large to have stopped diamond single line cut lengths position error, the drawback that the sapphire pipe concentricity is not good; Equally also avoid laser boring to stay the damage layer on the sapphire crystal surface, be unfavorable for the defective of hole inwall polishing.
Further improve as the present invention, in above-mentioned steps (1), described glue is epoxide-resin glue, and at room temperature solidifies more than 30 minutes, guarantees fixed; In above-mentioned steps (3), the rotating speed of described CNC milling machine is that 800rpm/min, feed rate are 6mm/min, in above-mentioned steps (5), the rotating speed of described CNC milling machine is that 400rpm/min, feed rate are 3mm/min, can guarantee production efficiency and machining accuracy like this.
The specific embodiment
The present invention is further illustrated below by specific embodiment.
To be fixed on the backing plate with glue without bubble, crackle and without the sapphire crystal of other obvious visual defects; Preferred embodiment is epoxide-resin glue, at room temperature solidifies more than 30 minutes; The sapphire crystal that is cured moved on on the CNC milling machine workbench and with anchor clamps fix; Start the vertical numerical control milling machine, the diamond drilling pipe that conforms to required sapphire pipe internal diameter is installed; Determine CNC milling machine cutter zero point; Bore the sapphire pipe endoporus, under rotating speed 800rpm/min, feed rate 6mm/min condition, utilize CNC milling machine to bore the sapphire pipe endoporus at sapphire crystal; Change the diamond drilling pipe conform to required sapphire pipe external diameter, redefine CNC milling machine cutter Z axis zero point; Bore the sapphire pipe cylindrical, under rotating speed 400rpm/min, feed rate 3mm/min condition, utilize CNC milling machine to bore the sapphire pipe cylindrical at sapphire crystal; The sapphire crystal that processes is moved on on the heated at constant temperature platform; It is 380 ~ 400 ℃ that heating-up temperature is set, and heats and is incubated more than 40 minutes; Take off sapphire pipe, at room temperature naturally cooling.
Adopting the technology of the present invention, have the advantages that processing is easy, processing cost is low, scale error is little, the surfaces externally and internally precision is high, can the rapid processing size range be the sapphire pipe of external diameter≤300mm, internal diameter 〉=25mm, length≤250mm.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
