For metallographic preparation, SiC abrasives are used in abrasive blades and for coated abrasive grinding papers ranging from very coarse 60 grit to very fine 1200 grit sizes. Bonded or coated abrasive papers of SiC are designed so that the abrasive will have a large number of cutting points (negative abrasive rank angle).
ECG • Electrochemical grinding (ECG) is an electrolytic material-removal process involving a negatively charged abrasive grinding wheel, a conductive fluid (electrolyte), and a positively charged work piece. • Work piece material corrodes into the electrolyte solution. ECG is similar to electrochemical machining except that the cathode is a specially constructed grinding wheel instead of a ...

We supply professional quality Superthin Cutting Discs, Cutting Discs, Grinding Discs, Abrasives Flap Discs and other Surface Condition Abrasives for customers from all of the world.
bonding material or ' bond'. The abrasive grains provide the wheel with its cutting points, which in turn help in cutting the material to the required dimensional accuracy or help impart a fine surface finish. The arrangement of the abrasive grain and the bond in the grinding wheel gives a definite characteristic known as 'structure' or 'pores'.
Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid.

The multibond coating allows the abrasive to provide for cool grinding as the multibond coating will evaporate at an early stage, resulting in evaporation heat loss. ... The consequences are, for instance, adhesions of electrically charged grinding dust on the adhesive belts, the machine or the work piece, which cannot be discharged even by the ...

A grinding wheel is an expendable wheel used for various grinding and abrasive machining operations. It is generally made from a matrix of coarse abrasive particles pressed and bonded together to form a solid, circular shape, various profiles and cross sections …
• The abrasive laden grinding wheel is negatively charged and the workpiece is positively charged. • They are separated by an electrolyte fluid. Electrochemical grinding and electrochemical machining are similar processes with a difference that a wheel substitutes the tool used in ECM. The wheel shape is similar to the desired work shape.
There is a whole science in the size of the starting material versus the ball size, shape material of construction and charge percentage of grinding media. All of these variables affect particle size, shape, and grinding efficiency. This type of grinding is very good for abrasive materials to prevent contamination.
Rubber-Cushioned Abrasive GrindingDiscs without Shank for Metals. The abrasive grains in these discs are blended with rubber, which cushions during grinding to produce a smoother surface texture than other discs with similar grits. Discs attach to your grinder with a shank.
Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour ...
A 1987 study by Hitchiner and Wilks showed that when grinding nickel, the chemical wear of a diamond single-point turning tool exceeded abrasive mechanical wear by 105x, highlighting the importance of using CBN in these applications 2. Using CBN requires fewer wheel changes and machine downtime, offers low and controlled wear rates, and ...

This slow temperature ramp fuses the clay bond mixture so that each grain is surrounded by a hard glass-like
Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
