Have you ever wondered how chainsaw chains are made?
It’s a surprisingly complex process that involves heat treating, hardening and tempering, drilling and gauging, sharpening, and quality control.
But what is the theory behind this complex manufacturing process?
It’s actually quite interesting.
The theory is that a chainsaw chain is made up of several components that are designed to work together for maximum efficiency and cutting power.
Once these components are built to the correct specifications, the chain is ready to be put to use.
In this article, we’ll take a closer look at the process of making chainsaw chains, from start to finish.
After being formed and sharpened, the components of the cutting tool get some extra TLC with heat treating!
Heat treating is the process of purposely heating and cooling metal in order to change its physical and mechanical properties. This process is used to increase the surface hardening of the cutting tool and to improve the edge retention.
Heat treating is done to increase the resistance of the cutting tool to wear and abrasion. Heat treating is done in a controlled environment, in which the metal to be treated is heated to a specific temperature, then cooled and quenched.
This process alters the physical and mechanical properties of the material, making it harder and more durable. The hardening of the cutting tool is done by applying a heat source to the metal to increase its temperature, then quenching it in a cooling medium such as oil or water.
This process increases the surface hardness of the metal, and improves the edge retention of the cutting tool.
Hardening and Tempering
You may be wondering how chainsaw blades are strengthened to stand up to tough jobs, and the answer lies in hardening and tempering – an old adage that says ‘what doesn’t kill you makes you stronger’ applies here!
In this process, cutting tools are used to form a blade and lubrication techniques are applied to reduce friction and wear.
Here’s a quick summary of the hardening and tempering process:
Heating: the blade is heated to a high temperature, usually in a furnace.
Quenching: the blade is then quickly cooled or quenched in oil, water or air to harden it.
Tempering: the blade is then reheated to a lower temperature and quenched again to temper it, making it tougher and less brittle.
This hardening and tempering process strengthens the blade, making it more durable and able to cut through tough materials.
The result is a blade that will last longer and make a cleaner cut.
Now that the blade has been hardened and tempered, it’s ready for the next step in the manufacturing process: drilling and gauging.
Drilling and Gauging
Once the blade is hardened and tempered, it’s ready for drilling and gauging. This process gives the blade a precise shape and size by creating the necessary holes and slots for the chain to fit its respective saw.
The size and position of the holes must be precise as they affect the chain’s performance. A lubrication technique is used to reduce friction and heat during this process. A variety of materials may be used due to the specific requirements of each chain.
The gauge of the chain must also be carefully selected to ensure that it fits the saw properly. Once these steps are completed, the blade is ready to be sharpened and tempered, taking the chainsaw chain from raw material to a perfectly crafted functioning part.
Sharpening your chainsaw chain is a critical part of the manufacturing process, and it ensures that it’ll perform at its best.
The first step in the sharpening process is to select a chain that’s of the right size, with the right pitch and gauge.
Once the right chain is chosen, the next step is to apply oil to the chain to ensure its teeth are lubricated and will remain sharp as they are being sharpened.
The chain is then placed onto a sharpening machine, and the teeth of the chain are sharpened to the correct angle and depth.
This process is done in a precise and accurate manner to ensure the chain will function properly when being used.
Once the sharpening process is complete, the chain undergoes rigorous quality control tests to make sure the chain has been properly sharpened and is ready for use.
Ensuring your chainsaw chain is of the highest quality is essential for a safe and successful job; that’s why quality control is essential.
Quality control is the process of testing and analyzing the chainsaw chains to make sure they meet safety standards and other requirements. It is done at every step of the production process, from raw material inspection to the final product.
Quality control technicians use a variety of testing methods, such as visual inspection, chemical analysis, and mechanical tests, to check the chainsaw chains for defects or inconsistencies. They also inspect the chains for any signs of wear and tear, and check for correct chain pitch, chain length, and overall chain durability.
The chainsaw chains must meet certain safety standards before they are approved for use, and any defects must be corrected before the chain is released for sale. Quality control is essential to ensure the safety of both the user and the chainsaw.
Without quality control, chainsaw chains may not be able to perform as expected, and could lead to dangerous accidents. Quality control is an essential step in the manufacturing process, and it helps to ensure that consumers are getting a reliable and safe product.
