(5) specific embodiment:
A kind of diamond-impregnated wheel of the utility model mainly is made of support wheel 2 and the grinding layer 1 that adheres on it as depicted in figs. 1 and 2, and grinding layer 1 comprises boart boart belt 1-1 and flexible transition layer 1-2.Boart boart belt 1-1 adopts the non junction fabricbase to be base material, to be that abrasive material is made with the diamond.Flexible transition layer 1-2 mainly made by elastic foam plastic, the rebound degree of this high-elastic foam plastic 〉=60%, compression set (70 ℃, 22 hours)≤8%.Loop configuration boart boart belt 1-1 is glued mutually by adhesive with loop configuration flexible transition layer 1-2, adhesive is mainly resin adhesive family macromolecule material, require the adhesion strength height of adhesive, and have certain water-fast, oil resistant, heat resistance fibre knitting cloth, foamed plastics.Adhesive is evenly coated ring surface and the outer ring surface of flexible transition layer 1-2 in the boart boart belt 1-1, make boart boart belt 1-1 and flexible transition layer 1-2 is smooth closely bonds together, and the composition that forms thus we be named as grinding layer 1, then that grinding layer 1 is glued mutually by adhesive with support wheel 2, this kind adhesive also is mainly the resin adhesive class, require its adhesion strength height, and have certain water-fast, oil resistance plastics.Adhesive is evenly coated the interior ring surface of grinding layer 1 and the outer ring surface of support wheel 2, makes then that grinding layer 1 and support wheel 2 are smooth closely to be bonded together.
In order to guarantee that flexible transition layer 1-2 gives each position uniformity of flexibility of boart boart belt 1-1, grinding layer 1 must be assemblied in support wheel 2 outer ring surfaces with certain tensioning, therefore, in assembling process, when grinding layer 1 cooperates with support wheel 2 when lax, need ring surface employing adhesive bonds one deck or which floor rubber rubber outside support wheel 2, be called gasket ring 3.Used adhesive requires the adhesion strength height to plastics, rubber.The smooth homogeneous of rubber rubber required thickness that gasket ring 3 is selected, generally selecting rubber thickness for use is 1mm, 2mm, 3mm totally 3 kinds, capable of being combinedly thus goes out gasket ring thickness 1mm, 2mm, 3mm, 4mm, 5mm, 6mm totally 6 kinds are arranged.
Diamond flexible grinding wheel specification is mainly determined according to circle diameter and two kinds of parameters of face width of boart boart belt 1-1, loop configuration boart boart belt 1-1 circle diameter is mainly 100 millimeters～255 millimeters (metric sizes, imperial sizing is 4 inches～10 inches), loop configuration diamond abrasive band 1 face width is of a size of 25 millimeters～51 millimeters (metric size, imperial sizing are 1 inch～2 inches).
Diamond-impregnated wheel support wheel endoporus 4 as shown in Figure 1 is assemblied on the equipment for grinding main shaft, under equipment for grinding drives, flexible grinding wheel rotates with certain rotating speed, grinding workpiece is pushed flexible grinding wheel boart boart belt 1-1 surface with certain pressure, thereby make diamond be carved into the grinding of surface of the work realization to workpiece, under the continuous grinding effect of countless diamond abrasive grains, the whole machined surface of workpiece is carved continuously got, thereby grinding goes out to have the plane or the curved surface of certain surface roughness.Because flexible transition layer 1-2 provide boart boart belt 1-1 with certain flexibility, thereby boart boart belt 1-1 can realize the grinding to workpiece under the condition of the surface configuration of not destroying workpiece, and has higher grinding life-span and grinding efficiency.
