Operational Difficulties and Their Solutions

PROBLEM REASON SOLUTION

The wheel wears out quickly;
Life is too short

Too soft; Suitable for other materials

Choose a harder grade wheel

Too thin

Work with a thicker wheel

The angle grinder operates on a low speed

Pick a high speed machine

Tool slows down

Reduce pressure or use a higher power machine
(watt

Low removal rate

Too hard wheel, edge becomes shiny;
Wheel glazing, material discoloring

Pick a softer grade or a rougher grain wheel

Diameter of the wheel is too small
as compared to the cross section of the material

Pick a larger diameter wheel

Machine is too weak

Use a more powerful tool

Wheel loading;
Wheel does not work anymore

Improper wheel
(problems occurring when working for example on
tool steel, stainless steel, aluminum)

Pick a softer grade wheel, a wheel with open structure;

Edge burning

Too hard wheel

Use a softer grade wheel

Too high feed, too much pressure

Lower the feed

Improper guiding;
Too long operation on the same spot

Move the wheel back and forth, if you stay on the
same spot too long the material will overheat and the
wheel will glaze over

Too much burr

Too thick wheel

Pick a thinner wheel

Too rough wheel

Use a fi ner grain wheel

Wheel edge is not holding,
chips breaking out,
wheel wears unevenly

Improper working angle, cutting wheel
is used for grinding

For grinding operations use grinding wheel
or Combi-Master

Wrong guiding of the wheel;
The wheel is blocked by a sharp burr

Guide wheel straight in the material

Work piece is not clamped properly,
it vibrates

Work piece shall be clamped close to the point of the
operation (managing the space where the cut pieces can fall)

Too low angle

Grind in 20-30 degrees, face grinding causes breakouts

Disc breakage

Wheel stuck in the cut

Wheel needs to be held straight in the cut to avoid
side pressure

Too high pressure on work

Reduce the pressure, the weight of the machine is enough

Incorrect wheel flange

Diameter of the fl anges shall be the same

Too much side pressure

For side grinding use Combi-Master! Cutting discs need to be hold straight in the cut, for grinding use grinding disc

Wheel vibrates

Wheel is unbalanced

Use a balanced wheel

Flange is damaged or spotted

Change or clean the fl ange

The machine is not maintained properly

Change the bearing

Improper clamping of the wheel;
Wheel is not centered

Check the diameter of bore, check the run after clamping

 
→ KEEP THE CUTTING DISC STRAIGHT IN THE CUT IN ORDER TO AVOID SIDE LOAD PRESSURE AND BLOCKING OF THE WHEEL! IF THE WHEEL IS BLOCKED IN THE CUT, THE FORCE OF THE MACHINE IS ABLE TO BREAK THE PART AROUND THE METAL RING!
→ DO NOT SIDE GRIND WITH CUTTING DISC!
→ You can cut a certain diameter work piece most economically, if you select the largest diameter cutting wheel and the most suitable angle grinder available!
→ The weight of the angle grinder ensures enough load, work without forcing the wheel!
→ For notching and light grinding use Combi-Master!
