Utility model content
The technical problem that the utility model solves is: be not durable for the emery wheel of superhard material in CNC process such as existing glass, pottery, sapphires, change troublesome problem, a kind of double mode emery wheel is provided, both the on-deformable advantage of electroplating abrasion wheel had been combined, inherit again metal sintering emery wheel converted products surface roughness low, the advantage that emery wheel is durable, thus CNC processing is simplified more, enhance productivity and product yield.
The utility model adopts following technical scheme to realize: a kind of double mode emery wheel, and the wheel grinding district of grinding wheel base body 2 comprises upper and lower two parts in the axial direction, and wherein a part is sintering washed ore district 4, and another part is plating coarse sand district 5.
Further, described grinding wheel base body 2 is provided with sintering groove 3, for filling mixed uniformly diamond dust and metallic bond and die casting sintering forms sintering washed ore district 4, described sintering washed ore district 4 adopts the diamond dust between 800# ~ 1200# to sinter, and the surface roughness after sintering is between 50 ~ 200nm.
Further, described plating coarse sand district 5 adopts diamond dust to electroplate on grinding wheel base body surface, and described plating coarse sand district 5 adopts the diamond dust between 180# ~ 800# to electroplate, and the surface roughness after plating is between 1000 ~ 1200nm.
Double mode emery wheel of the present utility model adopts two kinds of making patterns to form, in conjunction with the on-deformable advantage of electroplating abrasion wheel, plating coarse sand district is made into adopting the mode of coarse sand plating for rough machined position, coarse sand sand grains controls between 180# ~ 800#, shape of product in process is ensured, simultaneously low in conjunction with surface roughness during metal sintering emery wheel processing superhard material, the advantage that emery wheel is durable, sintering washed ore district is made in the mode being used for employing metal sintering in accurately machined position for emery wheel, washed ore sand grains is between 800# ~ 1200#, make the roughness of the surface of ultra-hard material processed low, make emery wheel more durable simultaneously.
From the above mentioned, the utility model adopts an emery wheel to be divided into two kinds of grinding areas, make an emery wheel have the advantage of electroplating abrasion wheel and sintering emery wheel simultaneously, the emery wheel of independent a kind of pattern of comparing improves emery wheel service life, most grinding requirements can be completed without the need to changing emery wheel in grinding, thus CNC processing is simplified more, enhance productivity and product yield.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
