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 powder or grit, we 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 agent. When suspended in a metal binding agent, the 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 size.

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 rate on diamond segments.

•Reduce load on the machine and cause the grinder to draw less current.

•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:

•Pressure.

•Hardness of bond.

•Diamond grit size.

•Number of segments under the machine.

•Adding an additional abrasive (e.g. sand, silicone carbide) on the floor will increase wear.

Generally, the faster a diamond segment wears, the faster the productivity will be. By varying the above factors, changes can also be made to effect the following:

•Scratch pattern.

•Current draw of machine.

•Flatness of floor (see next section).

•Ease of operation.

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 how hard the floor will be, and therefore, the 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 surface 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 therefore, require a soft bond segment.

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

Surface coatings/contaminants (e.g. Epoxy coatings, ceramic tile adhesives, levelling compounds/screeds) will often have a 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, always begin 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 abrasive surface or surface contaminant, it is quite possible to wear-out a considerable amount of diamond in very short period of time.

GRINDING GUIDE

Diamond selection

They way diamond segments are set-up on the grinding unit will greatly influence the performance of the machine, the productivity levels and also the finished floor quality.

There are a number of different diamond configurations that can be achieved on both the PG 400 SF and PG 280 SF.

MAINTENANCE

Faults and trouble shooting

The machine will not run

•Check the power supply and the power cables and make sure that they are not damaged.

•Check that the emergency stop button is not pressed by turning it clockwise.

Machine is hard to hold onto

•Not enough diamonds under the machine (if grinding thick glue or soft floors, too few diamonds under the machine will greatly increase the load on grinder and operator).

Usually also accompanied by high current draw by motor.

Increase number of diamonds under machine to reduce load on grinder and operator.

Machine is jumping around

•Rubber shock absorber pads in grinding unit may be worn out or damaged. Check and change if necessary.

•Diamonds may not be fitted correctly or have different heights. Check to ensure all diamonds are fitted correctly and are the same height.

The machine stops after just a while

•The machine is overloaded and the overload protection has been released. Reduce load. The machine will reboot after about a minute when the motor has cooled off.

The machine stops during start-up

•The electric motor has been overloaded or a phase is missing. Allow the machine one or two minues to reset and try again. When this does not help, contact an authorised service workshop.

Maintenance

IMPORTANT! Inspection and/or maintenance should be carried out with the motor switched off and the plug disconnected.

Used correctly, the machine is an extremely low-maintenance and reliable product.

Cleaning

Always pull out the plug from the outlet socket before cleaning, maintenance or assembly.

Always clean all the equipment at the end of the working day. Do not use a high pressure washer to clean the machine.

In order for the machine to always be cooled sufficiently the cooling air openings must be kept clear and clean.
