Description
Technical field
The utility model is related to diamond technical field of processing equipment, specifically relates to a kind of diamond abrasive intelligence machine
People.
Background technology
It is processed into the diamond referred to as diamond of jewellery.Exist on the crystal face of natural diamond crystal in various flaws, crystal
Portion can also have bubble, crackle, breach and other flaws.For being processed into the rough diamond of ornaments, designed, divided by decomposing scheme
After the process such as solution (split, saw or be cut by laser), wagon drill (edging line), the grinding and polishing for roughly grinding (grinding core), table top and valve face
Diamond finished product-jewellery could be turned into bore.
Abrasive drilling (grinding and polishing) is process the most complicated, the most key during diamond is processed.In order to do to the limit
Ground shows the optical characteristics of diamond, and modern diamond cut is designed as magnificent type cut, generally refers to the magnificent type of standard work
Round bur.Light can make " going out fire " and the gloss of diamond by the table top of the type finished diamond and the reflection and refraction in each valve face
Optimum degree is reached, the natural beauty of diamond crystal is played incisively and vividly.
The shape of chiseling of magnificent type round bur is made up of middle part sideline, face and bottom.Face is except perpendicular to diamond centers line
There are 32 valve faces outside table top into three circle arrangements, be referred to as valvula (16), main lobe (8) and star valve (8).This three circle
The geometric molding in valve face is the how equilateral pyramid of three different cone angles and different faces number.There are 24 valve faces bottom into two circle rows
Row, are referred to as bottom valvula (16) and bottom main lobe (8).The geometric molding in this two circles valve face is also two different cone angles and not
The pyramid of coplanar number.Bottom main lobe is finally all converged to a bit, referred to as the vertex (vertices) of finished diamond.
Abrasive drilling process seeks to perfect realize and above-mentioned chisels shape.The fixture of machine of the present utility model can adjust out different
Inclination angle, and 57 faces of finished product brill around the axis automatic indexing of itself, can be accurately ground by process.The shaping that finished product is bored is asked
After the key to exercises is determined, key is to improve the production efficiency of abrasive drilling.The efficiency of abrasive drilling can be described with abrasive drilling intensity, i.e., unit when
Interior rough diamond top layer removal amount.
The factor of influence grinding intensity is mainly following four：1, speed of grinding plate rotating speed is higher, and the grinding intensity of diamond is got over
Greatly；2, unit pressure, which increases diamond and the pressure of mill contact band, can increase the stock removal of diamond, but unit pressure crosses conference very
Diamond micro mist is wiped off soon, and accelerates the abrasion of mill, or even ruptures diamond；3, coating of the diamond micro mist in mill working face
Diamond micro mist particulate specification increases grinding intensity increase, but finish can be deteriorated, micro mist coating density abrasive drilling within the specific limits
Efficiency highest, this respect have accumulated rich experience data；4, the orientation of grinding.
Therefore, for first in aforementioned four factor, we are in supporting bench drilling burrstone mill of the present utility model
Speed of grinding plate is increased substantially.This is reached by fine dynamic balancing technique and variable-frequency driving technique.For the 3rd
Individual factor, we have grasped the empirical data of optimal diamond powder size and the coating density on mill working face.This
Utility model will to second, 4 two factors, i.e. abrasive drilling when compressive load per unit area and the aspect of grinding orientation two implement intelligent
Solution.
The crystal structure of diamond causes the anisotropy of its hardness.The position of veil must be found during grinding, and brill
Stone is positioned along the minimum direction of hardness, could produce highest grinding intensity.Rotation driving aligning device of the present utility model exists
Constantly change intelligent decision preferential orientation during direction, give and position.And by a set of automatic in grinding process
The mechanism regulation grinding force , And for changing spring tension produce optimum pressure value of the workpiece to mill by intelligent decision.
