Step by Step Process to Use a Bench Grinder

 

How to Use a Bench Grinder

Step 01: Do Safety Check

Before switching on the grinder, make sure you have taken necessary safety precautions as per below

  • Be assured; the grinder is securely positioned on the bench.
  • Inspect whether the tool rest is available in its place or not. The tool rest is a small portion of a bench grinder where the metallic item takes its place during grinding and it has to be placed securely. The space between the tool rest and the grinder wheel has to be 1/8”. Then only you can say the tool rest is secured.
  • If you find any debris and dirt all over the place of the grinder, clear it. Without enough room, you can’t effortlessly drive the cut of metal which you are dealing with to and fro in the grinder. So, enough spacing is mandatory in this regard.
  • During the working, the metal will get too hot, and you need to make them cool. So, keep a bucket of water near the metal grinder.

 

Step 02: Wear PPE

Protecting yourself should get top priority. Get necessary safety gears such as safety goggles, hardened toed gumboots, face mask and earplug. All these PPE will save you from flying metal sparks.

 

Step 03: Turn the Grinder On

Switch on the grinder. Don’t start working up to the grinder comes to its maximum speed.

 

Step 04: Start Grinding

Take your position at the front portion of the grinder. Take the metal piece and hold it tightly with your both hands. Put the metal piece at the tool rest and gradually drive it on the way to the grinder. The metal has to be in contact the edge, not to the side of the grinder.

 

Step 05: Dip the Metal into the Water when it gets cool

As I stated earlier, the metal piece will get hot due to excessive heat. So, dip the metal into a container of water periodically to keep it cool. When the heated metal touches the water surface, steam will be created, and you need to keep your face away from the steam at that time.

 

Step 06: Grinding a Metal

Let the metal move to and fro crosswise the bench grinder. And finish it only when the amount of metal is removed. Avoid holding the metallic piece in same place of the grinder for an extended period may create damage to the place.

 

Step 07: Cutting a Metal

  • Place the metal onto the tool rest. Gently rotate it and stop rotating when the grinder touches to the mark where you want to cut.
  • Keep on rotating, until it breakdowns apart. Don’t let the piece fall on the ground; be confirmed you hold both of the cut pieces in your hand. Once you are finished with the work, dip the hot parts into the water to make them cool.

 

Step 08: Giving a Shape to the Metal Piece

  • For giving shape to the metal piece, let the metal piece touch to the specific required bendable area. Give a to and fro motion. This way, the particular area will go off slowly.
  • When the metal piece becomes orange in color, be sure it is comfortable enough. And pull the metal away from the bench grinder. To give a shape to the metal piece, use your both hands. Once you gave the metal piece the ideal shape, dip it into the water.

 

Step 09: Sharpening a Blade of Metal

  • Place the metal blade at the top of the tool rest and grip it with your both hands securely.
  • Give the metal blade a slow push to the grinder. Slightly give the blade an up and down motion with an angle. This way, the metal cuts away to make the metal sharp. Continue the same process until the blade comes to your required sharpening point. Once the work is completed, take it away from the grinder, dip the metal into the water. After it gets cool, take it out of the water.

 


 

Tips

  • While you are working or cutting metal, make sure you are using the correct grinding wheel for your metal. A grinding wheel works similar to sandpaper. To perform different precision work, they are made differently. Majority of the grinding wheels are prepared to give a gentle rub to any metallic objects.
  • At the time of working with a grinding wheel, don’t wear hand gloves. It is prohibited because if the gloves come in contact with a running wheel, you may fall into a severe problem. Even a glancing touch to the wheel can remove your skin. However, you can use light latex gloves to protect your hands from irritating dust.
