Using a Tool and Cutter Grinder

If what you have is a manually operated tool and cutter grinder, operating it requires a lot of skill. You should be familiar with the relationship between the workpiece and the grinder wheel as well as tool geometry.

Moreover there are a range of types and shapes for machine cutters so you need to have some flexibility as well. There are certain features, which enable grinding on complicated angles and cylindrical surfaces.

The grinder is made up of a vise, which swivels across 3 planes as well as a table, which moves both longitudinally and laterally. The head can also swivel and adjust and it is this flexibility that makes the grinder able to make unusual cutting angles.

Safety Precautions

Grinding and cutting are done on many jobsites. I’ve created a list of safety precautions that you need to follow to avoid injury or property damage.

  • Always be aware of what you’re doing. Do not use the machine if you’re tired or under the influence of alcohol, drugs or medications.
  • Don’t wear loose clothes or jewelry while operating the machine. Long hair must be tied and held back to prevent getting caught in the machine.
  • See to it that the machine is switched off before you plug it to a power outlet.
  • Maintain balance and proper footing at all times so you can have better control of the machine.
  • Wear safety goggles, protective gloves and other safety gear. Anyone going near the machine should have proper gear as well.
  • Always use a proper guard to protect you from broken wheel fragments. Make sure the closed area is towards you.
  • Let the machine warm up first before working.
  • Do not go past the recommended speed. Wheels running over the recommended speed can fly apart, along with other accessories and may cause injury.
  • Always use the equipment with the side handle and keep both your hands on the equipment.
  • See to it that the sparks produced during work do not become a risk to anyone and don’t ignite inflammable substances. Keep areas protected using covers that are flame-resistant. Fire-risk areas should have standby fire extinguishers.
  • Conduct a test run every time you change tools, and make sure you’re holding the angle grinder securely with both hands. Keep the angle grinder as far from your body as possible.
  • The angle grinder runs on for approximately 5 seconds after switch-off. Do not attempt to touch the moving tool due to risk of injury.
  • Don’t use cutting discs for the purpose of grinding. Cutting discs shouldn’t be subject to lateral pressure.
  • Keep in mind that grinders work in a continuous operation. In order to prevent an unintentional startup, turn off the switch after removing the plug from the socket as well as during a power interruption.
  • Use only accessories that meet the minimum requirements in relation to the maximum grinding-disc diameter. The central hole’s diameter in the grinding disc needs to fit the inner flange. Reducers or adapters should not be used.
  • Secure the workpiece using a clamp. Not having any secure fitting can make the workpiece unstable in the machine.
  • Never force any tool into the machine. Use the proper tool for each application as it will do a better job and ensure your safety.
  • Abrasive wheels need to be handled and stored with care. Follow the with manufacturer’s instructions on how to care and store them.
  • Remove the plug from the power source prior to doing any adjustments or change of accessories. You don’t want to start the machine by accident.
  • It’s vital that you use only those accessories that the machine’s manufacturer recommends, specifically for the model that you have.
  • Examine the tool prior to each use so that you can check if the edges are sharp, if the switches work and if the clamp nut is secure. You should also check the ventilation openings, the disc thread, the disc and the moving parts.

How to Prevent a Kickback

Are you familiar with the term, kickback? It is basically a sudden reaction to a misaligned, pinched or bound wheel. When this happens, it triggers an uncontrolled cut-off tool to rise up and go out of the workpiece in the direction of the machine operator.

It happens due to the misuse or incorrect use of the tool. It could also stem from the incorrect operating procedures. To avoid a kickback, you should keep in mind the following:

  • You need to have a solid grip of the equipment using both your hands. Your body position should allow you to resist forces that trigger a kickback.
  • Release the trigger and hold the machine when the wheel is binding until it comes to a complete stop. Don’t remove the unit from the work or pull it backward if the wheel is still moving otherwise a kickback may occur.
  • If you need to restart a cut-off tool in the workpiece, make sure the wheel is not engaged into the work. If it is, it may kickback from the workpiece when you restart it.
  • If you have large panels, make sure they have proper support to minimize the risk of wheel kickback. Due to their own weight, large panels tend to sag. Make sure both sides have support as well as the edge of the panel and line cut.
