Diamond selection

Full and half sets of diamonds

By changing the way the diamonds are set-up on the diamond holder discs, an operator can significantly ef- fect the performance of the machine and therefore, the finished product.

HALF-SET OF DIAMONDS

When the diamonds are set-up as a half-set, they tend to follow the surface of the floor. Similar to a tripod for a camera, which can be placed on an uneven surface and yet still find a stable footing.

The half-set diamond configuration should only be used when a flat floor finish is not required.

FULL-SET OF DIAMONDS

When the diamonds are set-up as a full-set, they tend not to follow the surface of the floor. If the floor has undu- lations, the machine will grind the high areas yet miss the low spots (unless the high areas are ground down first).

The full-set diamond configuration should be used when a flat floor finish is desired.

The below table gives some examples of possible ap- plications for the two arrangements:
