I’m only a learner, but if you follow the basics you can end up with very flat pieces of metal.
You need the right grade of wheel if after the optimum finish on any particular item.
A balanced wheel is (apparently) far better on that is not.
Check wheels for any cracks before putting into use.
More small cuts is preferable until you become experienced.
Wheels are consumables, so regular use of a diamond, to trim that wheel surface, is very worthwhile.
Heat is one of your main enemies – if the item warms, it expands and the wheel cuts (or tries to cut) deeper, with unwanted consequences.
Cooling is important, if you have the facility.
You will not necessarily flat thin materials – the magnetic table will distort it, if precautions are not taken.
Take extra care with small items – they can be fired off the bed like bullets.
The experts can make it look easy. It is not.
