Grit sizes

Ordering data

The following data must be given when ordering diamond tools:

- Shape of required tool

- Dimensions including bore size/mounting (machine connection)

- Grit size(s)

- Bond together known as the specification

- Concentration

Ordering examples are given with all tables in this catalogue, so that you can check for yourself whether your data are

complete.

Diamond tool shape

We recommend that specification should always take account of the following key factors:

- For reasons of cost-effectiveness, it should be possible to use up the grinding layer as completely as possible.

- La-yer depth and layer volume should be specified as large as possible (if necessary after testing), because the

manufacturing cost is virtually unchanged for a greater depth of layer, so that twice the layer depth costs less than

twice the price.

- Wheel diameter should be specified as large as possible, in order to improve the cost ratio (manufacturing cost

to layer volume cost).

Diamond grit sizes

The grit size table shows the diamond

grit sieve sizes, which have the same

specifications in DIN, ISO and FEPA

standards; micron sizes are supplied

under WINTER micron powder

designations.

Please note that larger grit sizes per-

mit higher material removal rate Q

in cm

/min; at the same time tool

life is longer (grinding ratio G in cm

), but the generated workpiece

surface is rougher. The following rule

should be applied for specification of

grit size: as coarse as possible, as

fine as necessary.

*) Similar FEPA standard exists with designations
