Setup a sanding pattern
Work from low to high grit. Do not make too large steps from low to high grit, because you will continue to see the sanding stripes of the lower grain. For example, you cannot go from grit 60 to 220 in one step. How large the steps are is something you have to experience for yourself.

Select your belts
You can find your suitable sanding belts by selecting from 4 criteria:

  1. – application: hard or no hard steel, wood, plastic, glass, etc.
  2. – grit: remove a lot of material or fine finish
  3. – backing: pressurized or flexible sanding
  4. – cooler grinding to avoid burn marks

Some examples:
Forcefully removing a lot of material from rock-hard damast or titanium: low grit Ceramic Agressive or Cubitron with an X-backing
Finishing very hard steel, a workpiece with many curves: high grit Ceramic belts with a JF backing.
Cool and fine grinding of stainless steel, aluminum and non-ferrous steels in order to avoid burning marks: LS313 belts.

Application: your materials
Aluminium-oxide: for wide application, such as (non-hard) steel, wood, plastic, glass.
Cubitron and Ceramic for the very hard steels.
Zirconium and SiliconCarbide for the hard steels.
Belts that are specific for non-ferro steel, stainless steel, glas, rubber, minerals, ceramics, wood, plastic.
Select your material in APPLICATIONS

Grit: coarse, edit, finish or polish
Material removal: grit 34 to 150.
Edit: 150 to 240 grit.
Fine finishing: 240 to 400 grit.
Glossy semi-gloss finish: SHINE Cork (up to grain 800).
Matt finish: Fleece / Scotchbrite (up to grain 1200).
Fine mirror finish, polish: Trizact (up to grain 2000).

Backing: pressure or flexible grinding
The backing of the belt decides if you perform grinding with pressure of perform flexible grinding:
a) X-, Y- and F-backings: made of hard polyester. The workpiece can be held with pressure against the sanding belt.
b) JF-backings: made of flexible linen. Ideal for flexible grinding round shapes, sanding or profiles and contours.

Cooler grinding to avoid burn marks
If you want to reduce the risk of burn marks, too much heat or softening of the workpiece.
