How to sharpen a chainsaw chain with a grinder
Sharpening a chainsaw chain with an angle grinder requires accuracy and safety precautions. Here is a step-by-step instruction:
You will need:
An angle grinder with a thin abrasive disc (about 1.5 mm thick).
Safety glasses and gloves.
A vice for fixing the chain.
A marker for marking the starting link of the chain.
Instructions:
Preparation:
Put on safety glasses and gloves.
Secure the chain in a vice so that the links cannot move. If the chain is installed on a saw, you need to fix the saw or remove the chain and clamp it separately.
Marking the first link:
Use a marker to mark the first link that you will sharpen so as not to get lost during the sharpening process.
Sharpening angle:
Determine the sharpening angle. Usually it is about 30 degrees for standard chains, but it is better to check in the instructions for your chain.
Sharpening:
Turn on the grinder and carefully bring the disc to the cutting edge of the chain link at the desired angle.
Gradually touch the cutting surface of the tooth with the disc, trying to remove only a small amount of metal.
Go over each tooth, maintaining the same angle and amount of material removed.
Checking and adjusting:
After going over all the teeth, check how sharp the chain has become. If there are teeth that require additional processing, carefully correct them.
Treating the depth stops (if necessary):
If the teeth are heavily worn down, it may be necessary to shorten the depth stops (located in front of each tooth). To do this, use a flat file or grinder, but be careful not to remove too much material.
Lubricating and installing the chain:
After sharpening, make sure the chain is lubricated and install it on the chainsaw.
Important tips:
Do not remove too much material from the teeth, this can reduce the service life of the chain. Work carefully so as not to overheat the metal, otherwise it may lose its properties.
If you doubt your abilities, it is better to contact specialists or use a specialized machine for sharpening chains.
This technique requires skills and accuracy, but allows you to sharpen a chainsaw chain at home without special machines.
