For example, double disk grinding can achieve surface finishes of up 16 ra in 0.41 m on aluminum and up to ra 8 in 0.20 m on ferrous alloys. flat lapping is another abrasive process often considered an alternative to double disk grinding for tight control of surface finish, flatness, thickness, and parallelism.

A device for the simultaneous doubleside grinding of workpiece wafers has two collinear grinding wheels and two hydropads oppositely positioned for hydrostatic bearing of the workpiece, each having at least one hydrostatic bearing and at least one dynamic pressure tube for measuring the spacing between the workpiece and the hydrdopads.
A method for the simultaneous doubleside grinding of a plurality of semiconductor wafers, involves a process wherein each semiconductor wafer lies such that it is freely moveable in a cutout of one of a plurality of carriers caused to rotate by means of a rolling apparatus and is thereby moved on a cycloidal trajectory, wherein the semiconductor wafers are machined in.
I worked at a double disc grinding job shop for 15 years, and ground a lot of problem parts. if you find that there is plenty of material to remove another thing to look at is the area to be ground. because the wheels are typically the same spec on each side the stock removal will only be even if the surface area is the same.

Double disc grinder rebuilds amp; upgrades cincinnati milacron grinders • besly grinders • gardner grinders • koyo grinders • mattison grinders • giustina grinders and more. in today's competitive environment, manufacturers cannot gamble with grinding equipment that is unreliable or unable to consistently produce parts within specification.
Double disc grinding services. doubledisc grinding is an extremely efficient grinding process that uses abrasive wheels that oppose one another, grinding and removing equal amounts of stock from both sides of a blank. the result is a flat aluminum or stainless steel machineready blank with parallel tolerances to .0005 and finishes to 16 ra.
Double disc grinding uses two opposing abrasive wheels to simultaneously grind two sides of a blank. in one operation, equal amounts of material are removed from both sides making this a very costeffective grinding option.

Doubledisk grinding considered one of the classic grinding processes, doubledisk grinding is performed when both sides of a workpiece must be ground so that both surfaces are exactly plane and parallel. the workpiece is not fixed for this process. instead, it is loosely placed in the nest of the workpiece carrier.

By double grinding we went from a typical 65 to 70 75. we aren't using a false bottom. we use a full circle braid loop. we read many times that false bottoms while great for fly sparging, were easily plugged when batch sparging. so we use a braid clamped to two ends of a 38 tubing tee. the third end is pushed into a drilled 2 stopper.
Fine grinding (flat parts – single or doubleside) is the abrasive machining process for removing material using a bonded superabrasive wheel at low speed with a liquid to keep the part cool. the fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by microgrooving cutting (fig. 4).

A doublesided grinder also known as a vertical machine. it uses a vertical grinding wheel in either side of a fixed flat grinding plate at the other end. in a vertical machine, the work piece is passed through the grinding wheel and then turned off at the opposite end.
True to its name, double disk grinding uses two opposing abrasive wheels to grind two sides of a material at the same time. this makes it a very efficient grinding method for achieving a tight tolerance surface finish, flatness, and parallelism in the right applications. yet there is somewhat of an aura of mystery surrounding double disk grinding.
