Manufacture of a Tungsten Tipped Circular Saw


There are many saw blade manufacturers around the world. There are only a couple of saw blade manufacturers in Australia. A Victorian company called Central Saws have invested a lot of time in developing Australia’s leading high quality professional circular saws for a variety of industries.

The process of manufacturing the saw blade is fully automated ensuring a high precision quality blade.

What determines a good quality blade?
  1. The quality of the steel so it can hold it’s tension to keep the blade in a straight cutting line whilst sawing.
  2. The grade of the tungsten tip. There a many grades of tungsten tips. The high end quality blade uses a Ultra Micro Grain tungsten tip. It is this quality of tungsten tip that makes the cutting edge stay sharper for longer.
The making of a tungsten tipped circular saw:
  1. The first step in manufacturing the saw blade is the design of the blade.  The design of the saw blade is drawn using a CAD program.

  2. The second stage is to transfer the drawing to the Laser cutting machine which cuts out  the saw blade in the sheet of steel.

    Once the saw blade has been cut out, it is then heat treated and the blade is tensioned.

  3. The next stage after tensioning the saw blade is to braze the tungsten tips onto the saw blade.

    The brazing machine is fully automatic. The number of teeth on the saw blade is entered into the computer on the machine and a mechanical feed pawl indexes the saw blade to the next tooth and the brazing process is repeated.

    Once the brazing process has been completed the saw blade is then polished.
  4. The next process after polishing is side grinding.

    The saws are stacked onto the carriage on the robotic machine.

    There are two different sharpening machines that the robotic arm places the saw blades onto. The first machine is the side grinding machine. The purpose of the side grinding machine is to side grind the kerf of the saw to a even width on both sides of the saw. The kerf is the width of cut.

  5. Now that the side grinding process has been completed the robotic arm would then place the saw blade onto another stack. Another robotic arm picks up this saw blade and places it onto the sharpening machine. This is the final process in manufacturing a saw blade.

  6. The final process in the manufacturing of the TCT blade is to sharpen the tops of the teeth into the required tooth style.

    The saw blade is now a finished product. The blade is inspected before packaging and is now 100% guaranteed.

    There you have it. Hope you have enjoyed the making of the saw blade from start to finish.

    It’s good to see that a regional Victorian company is designing and developing saw blades

    for not only us to use in Australia but also to export around the world.

    Until next time.....Happy cutting!!!
