How to measure and maintain good performance of chain saws？

Chain for chain saw manufacturer and supplier in China

chain for chain saw is a commonly used tool in wood cutting, and its cutting performance mainly depends on the sharpness of the chain. In order to ensure good cutting performance of the chain saw, we need to regularly test and maintain the sharpness of the chain. This article will explain how to measure and maintain good cutting performance of chain for chain saw.

1. Test method for the sharpness of chain for chain saw

Observation method: Judge the sharpness of the chain for chain saw by observing the cutting marks of the chain. If the cutting marks are obvious and smooth, it means that the chain sharpness is good; If the cutting marks are fuzzy and stuck, the chain sharpness is poor.
Hand feel: Touch the cutting edge of the chain for chain saw with your hand to feel its sharpness. If the cutting edge is sharp, the feel is more stinging, indicating that the chain sharpness is better; If the feel is blunt, the chain sharpness is poor.
Pressure method: Place the chain on a hard object, apply a certain pressure, and observe the cut marks of the chain. If the cutting marks are obvious and smooth, it means that the chain sharpness is good; If the cutting marks are fuzzy and stuck, the chain sharpness is poor.
Professional testing equipment: The use of professional chain sharpness testing equipment for measurement. The chain is placed in the instrument and the cutting force of the chain is measured by simulating the cutting process. The smaller the cutting force, the better the sharpness of the chain.
Second, the method of maintaining good cutting performance of the chain for chain saw

Regular grinding: The chain for chain saw in the process of use, due to friction with the wood, the cutting edge will gradually become dull. In order to ensure cutting performance, we need to grind the chain regularly. In general, the chain is ground once every 10-15 hours of use.
Use suitable grinding tools: When grinding chains, use special grinding tools, such as chain grinding machines, grinding rods, etc. These tools ensure that the chain maintains the correct Angle and shape during grinding.
Selection of high-quality chain for chain saw: high-quality chain has a good guarantee in terms of material, heat treatment process, etc., and its sharpness and durability are stronger. Therefore, when buying a chain saw, choose a well-known brand and a high-quality chain.
Avoid cutting hard objects: When using a chain saw, try to avoid cutting hard objects, such as metal, stone, etc. These hard objects are easy to damage the chain and affect its cutting performance.
Keep the chain for chain saw clean and lubricated: the chain in the process of use, easy to be contaminated with wood chips, soil and other impurities, affecting its cutting performance. Therefore, clean the chain regularly and keep it lubricated. Special chain oil can be used for cleaning and lubrication.
Replace the badly worn chain: When the chain is badly worn and cannot be repaired, replace the new chain in time. Continue to use the chain with serious wear, not only affect the cutting effect, but also may cause safety accidents.
In short, to ensure good cutting performance of the chain for chain saw, we need to master the correct sharpness test method and take corresponding maintenance measures. By grinding regularly, using high-quality chains, avoiding cutting hard objects, keeping the chain clean and lubricated, the service life of the chain can be effectively extended and the cutting efficiency can be improved. At the same time, pay attention to safe use, comply with the operating procedures, to ensure personal and property safety.
