Why is safety critical when using cutting and grinding discs?

Abrasive discs are essential in many industries, from metalworking to construction. However, improper operation can lead to serious accidents, ranging from injuries to catastrophic equipment failure. At FANDELI, we take safety seriously, which is why we have developed a comprehensive program based on the ANSI B7.1 standard to ensure the safe use of our cutting and grinding discs.

1. Always wear personal protective equipment (PPE)

• Before operating any tool, ensure you are wearing the appropriate personal protective equipment (PPE).
• Safety glasses
• Dust mask
• Hearing protection
• Heavy-duty gloves
• Work shirt and pants
• Steel-toed shoes
• Hard hat and face shield for more demanding operations

Why is this important?
PPE is the first line of defense between the operator and potential accidents. No matter how experienced you are, safety is never optional.

2. Verify the maximum speed of both the disc and the machine

Each FANDELI disc indicates its maximum safe speed (MAX RPM or MSFS). Before mounting the disc, check that the machine does not exceed this limit. An inappropriate speed can disintegrate the abrasive in seconds.

⚠️ FAQ

Can I use a higher RPM disc on a slower machine?
Yes, but never the other way around. Never mount a disc with lower RPM tolerance on a faster machine.

3. Visually inspect each disc before use

Not all damage is visible to the untrained eye, but a quick inspection can prevent disasters:

• Look for cracks, chips, scratches, or deformations.
• Do not use the disc if it has fallen.
• Always inspect the flanges and protective guard as well.

👉 FANDELI Expert Tip: If you are in doubt about a disc, discard it and replace it. Safety first — avoid accidents before they happen.

4. Correct storage: essential for the disc’s longevity

Abrasive discs are delicate and can be damaged by moisture, extreme temperatures, or exposure to solvents.

Store them in:

• Their original packaging
• A horizontal position
• A flat, dry shelf
• Away from vibrating sources

FANDELI #FirstInFirstOut rule: Use the oldest discs first. Avoid prolonged storage.Forma

5. Correct assembly = Safe operation

Follow these steps when mounting a disc:

• Use the manufacturer’s
• Tighten without hitting or forcing
• Never modify the disc’s bore
• Always use original, flat, and clean flanges
• Let the disc spin idle for at least 1 minute before use
• ⛔️ It is forbidden to mount more than one disc per axle.

6. Do not operate without the protective guard

The guard is a shield against fragments in case of breakage. Verify that:

• It covers at least 180° of the disc.
• It is securely fastened.
• It is not made of weak materials such as plastic or zamak.
• It allows the disc to be changed without removing it.
• Important: Never operate a machine without a safety guard.Forma

7. Proper pressure: not too much, not too little

The recommended pressure for FANDELI discs is between 1.4 and 2.5 N/mm², which is the equivalent of the force needed to cut fruit with a knife.

Too much pressure:

• Increases heat
• Wears down the disc
• Causes breakage

Not enough pressure:

• Reduces effectiveness
• Can cause the disc to skip

8. Correct cutting and grinding techniques

For cutting:

• Accurate 90° angle
• Avoid curved cuts
• Never use cutting discs for grinding

For grinding:

• 25° to 35° angle
• Avoid angles lower than 15°, as they cause imbalance
• Use steady back-and-forth movements
• Do not overload: Allow the abrasive to do its job

9. Avoid vibration: make sure the workpiece is securely clamped

Excessive vibration:

• Will prematurely wear out the disc
• Increases the risk of material jamming
• Can uncontrol the tool

🔧 Always fasten the workpiece as close as possible to the cutting or grinding point.
Operating and not clamping the workpiece securely is a recipe for disaster.

10. Ongoing training and maintenance

FANDELI offers specialized courses on:

• How to assemble and read disc labels
• Storage and transport
• Use of guards, clamps, and adapters

It is also key to:

• Check the actual RPM of your tools after every maintenance job
• Inspect portable electric or pneumatic grinders
• Not use modified equipment

🚨 Remember: Over 50% of all accidents happen because of operational errors or unsafe conditions. Training saves lives.

FAQ

– What happens if I use a damaged disc?
It may break during operation and throw fragments at high speed. Discard it immediately.

– Can I use a cutting disc for grinding?
No. Each type of disc has a specific application. Misusing them shortens their service life and jeopardizes your safety.

– What is the most common cause of breakage?
Excessive RPM, incorrect mounting, or a disc damaged by mishandling or improper storage.
