摘要:
A supporting device (1) is described for supporting and containing an abrasive element (5) for the machining of stone, ceramic or similar, said supporting device (1) comprising an elastic means (6) for absorbing the external stress on said abrasive element (5); said supporting device (1) comprises an upper half-box (3b) and a lower half-box (3a) which comprise reciprocal engagement means (7), thus forming a housing box (3) able to accommodate said elastic means (6) and able to retain said abrasive element (5), said reciprocal engagement means (7) being suitable for permitting the sliding of said upper half-box (3b) towards and away from said lower half-box (3a). An abrasive tool (2) is also described for machining stone or similar, comprising an abrasive element (5) and a supporting device (1) for supporting and containing said abrasive element (5).
摘要:
An improved method for synthesizing superabrasive particles provides high quality industrial superabrasive particles with high yield and a narrow size distribution. The synthesis method includes forming a substantially homogeneous mixture of raw material and catalyst material or layers of raw material and metal catalyst. A plurality of crystalline seeds is placed in a predetermined pattern in the mixture or one of the layers to form a growth precursor. The growth precursor is maintained at a temperature and pressure at which the superabrasive crystal is thermodynamically stable for a time sufficient for a desired degree of growth. Advantageously, the patterned placement of crystalline seeds and disclosed processes allow for production of various morphologies of synthetic diamonds, including octahedral and cubic diamonds, and improved growth conditions generally. As a result, the grown superabrasive particles typically have a high yield of high quality particles and a narrow distribution of particle sizes.

A grinding wheel has a disc having a connection hole formed at a center thereof, to which a rotation axis of a grinder is connected, and a plurality of abrasive segments detachably connected to a surface of the disc. A plurality of fixing recesses are radially formed on the surface of the disc at an interval and fixing protrusions having a shape corresponding to the fixing recess are formed on bottom surfaces of the abrasive segments, so that the abrasive segments are connected to the disc by inserting the fixing protrusions into the fixing recesses. According to the grinding wheel, when the abrasive segment is worn away or inferior as it is used for a long time, it has only to replace the corresponding abrasive segment only. Accordingly, an economical efficiency is high.

Superabrasive tools and methods for the making thereof are disclosed and described. In one aspect, superabrasive particles are chemically bonded to a matrix support material according to a predetermined pattern by a braze alloy. The brazing alloy may be provided as a powder, thin sheet, or sheet of amorphous alloy. A template having a plurality of apertures arranged in a predetermined pattern may be used to place the superabrasive particles on a given substrate or matrix support material.
摘要:
A whetstone pellet 1 is composed of a columnar base body 2 to be fixed on a pedestal 9, and an abrasive grain part 5 containing numerous abrasive grains formed by electroless plating on an end surface 3 of the base body 2. Upon forming the abrasive grain part 5, a plated layer is formed on the end surface 3 of the base body 2 under stirring a plating solution containing abrasive grains, whereby the distribution of the abrasive grains in the abrasive grain part 5 can be uniformized.

Meule de surfaçage destinée à l'enlèvement de revêtements sur supports minéraux, constituée d'un corps (10) percé de trous (11) garnie de segments en forme de soc de charrue présentant 2 flancs long (1) et court (2) par rapport à la direction de rotation, constitués de deux couches (3) et (4), la face (3) étant inclinée d'un angle (5) par rapport au plan de base du segment (6). Ces segments sont disposés selon au moins deux dispositions, notamment des segments (8) avec l'axe du profil tangent au cercle passant par la pointe du profil et des segments (9) dont le flanc court est tangent au cercle extérieur correspondant à la périphérie de l'outil.
