With such a wide range of options, how do you select the correct belt for your particular grinding, finishing or polishing process? All our product pages are filtered to help you find the right belt and if you are still unsure then there are also the faq’s at the bottom of this page.
Abrasive Belts for Grinding & Finishing Metal FAQs
How do I choose the right abrasive grit type for my job?
Ceramic Abrasives - The toughest and most durable abrasive grit. Use it on hard metals and in high pressure grinding applications such as belt grinding of steels on both backstand grinders and powerfile belts
Zirconia Abrasives - Tougher than aluminium oxide grit zirconia has, for a long time, been the most common product used for metal grinding but the new Cibo Ceramics are becoming the first choice option
Aluminium Oxide Abrasives - The most common abrasive grit. Excellent for metal finishing applications and the best and first choice for wood sanding.
Silicon Cabide Abrasives - A much sharper and more friable abrasive. Silicon carbide grit cuts like a knife and is therefore excellent for use on lacquers and resin coatings where you need to cut back the surface.
We have a more detailed blog which explains the differences between the various abrasive grits. You can read this blog here
What grit size should I use?
The million dollar question...
If you ultimately require a bright polished finish then at step 1 use the finest grit size capable of effectively removing the initial metal stock, this will save you time during the final polishing process.
If you are grinding only and finish doesn’t matter then go for the most aggressive and most powerful belt to improve lifetime and the speed of cut. e.g.
- Notching steel tube in preparation for mig welding: P36 grit HZ72 zirconia or preferably our FX87 P36 grit ceramic belts
- Notching thin walled stainless steel tube in preparation for tig welding: P60 FX87 ceramic belts
What difference does abrasive belt flexibility make?
For backstand grinder belts (2000 x 75, 2000 x 100 etc) the grinding pressure will be higher so a good strong, preferably polyester backed cloth is ideal. For more detail sanding where you are working on the slack of the belt (such as is sometimes the case with a vertical linisher – belt sizes 1525 x 25, 1065 x 25) or powerfile belts then flexibility can be more important.
