GRINDING GUIDE

Diamonds

Background

Diamond abrasives usually consist of 2 components:

• Diamond powder (also known as diamond crystals or grit). By changing the size of the diamond po can change how coarse or ﬁne the scratches will be that are left behind from the grinding process.

• A binding agent (metal or resin). Diamond powder is mixed and suspended in either a metal or resin binding

When suspended in a metal binding agent, the

agent. ﬁnished product is referred to as a Metal Bond or Sintered diamond segment. When suspended in a resin binding agent, the ﬁnished product is referred to as a Resin Bond diamond segment or pad. By changing the hardness of the binding agent, we can change how fast or slow the diamond abrasive will wear.

General Principles

The following are general rules regarding diamond segments in grinding applications. As with all general rules there are exceptions or cases when it is not the case.

Diamond grit size

Changing the size of the diamond grit to a smaller particle/grit size will effect the performance of the diamond tool in the following ways:

• Create a ﬁner scratch pattern.

• Increase life of diamond tool.

The opposite will occur when changing to a larger particle/grit

ize.

Binding agent

Increasing hardness of bond will:

• Create a ﬁner scratch pattern.

• Increase life of diamond tool.

• Decrease production rate.

The opposite will occur when making the metal or resin bond

softer

Number of diamond segments/pads under the machine

Increasing the number of segments under the machine will:

• Reduce pressure on each individual diamond segment reduce wear r

• Reduce load on the machine and cause the grinder to

w less current.

dra

• Create a smoother scratch pattern (particularly on soft ﬂoors).

The opposite will occur when decreasing the number of segments under the machine

Summary of diamond principles

Diamond segments need to wear in order to achieve productivity . Diamond segment wear can be inﬂuenced by the following factors:

• Diamond grit size.

Generally , the faster a diamond segment w ears, the faster the productivity will be. can also be made to effect the following:

• Scratch pattern.

• Current draw of machine.

• Flatness of ﬂoor (see next section).

• Ease of operation.

By varying the above factors, changes

Determining the hardness of concrete

All concretes are measured by their compressive strength and depending on which part of the world you are from, different compressive strength indices (e.g. PSi & MPa) are used. Generally, the higher the compressive strength rating, the harder the concrete and therefore, the harder it will be to grind.

However, other factors beside compressive strength ratings determine ho correct diamond selection. Since grinding normally only deals with the surface of the concrete (top 5mm or 1/4 inch), often the way the concrete ﬂoor has been ﬁnished or the condition of the surface will have a greater bearing on what type of diamond to select, rather than the compressive strength rating of the concrete.

Surface factors to consider when making a diamond selection

Generally , if a concrete surf ace is very smooth (i.e. Most likely it has been heavily trowelled/helicoptered), the concrete will behave as if it has a high compressive strength and theref ore, require a soft bond segment.

Accordingly, if a concrete surface is coarse/aggressive (e.g. rain-damaged, shot b e.t.c.), the concrete will behave as if it has a lo w compressive strength and therefore, require a hard bond segment.

Surface coatings/contaminants (e.g. Epoxy coatings , ceramic tile adhesives larger bearing on what diamond to select, than will the compressive strength of the concrete.

As a general rule, when grinding a concrete slab for the ﬁrst time and you are unsure about its hardness with harder bond diamonds under the machine. This will ensure the least amount of wear on the diamond segments. If a hard diamond segment is not suited to the application, all it has cost is a little amount of time without wearing out the diamonds.

If performed the other way around (i.e. a soft segment is used to begin with) and the concrete is soft or possesses an abrasiv wear-out a considerable amount of diamond in very short period of time.
