Do you know all about saw chains?
The saw chain generally consists of four parts, including the cutter head, the middle guide tooth, the connecting piece and the rivet. Wherein the cutter head is divided into left and right cutter heads, and the connecting piece is divided into left and right connecting pieces. Some saw chains have buffer designs to reduce the rebound of cutting. These parts with buffer features include buffer intermediate guide teeth, buffer connecting pieces, etc.
Saw chain structure
The middle guide tooth is a transmission part, and its thickness is an important parameter of the saw chain.
The cutter head is the main body of cutting, and its design determines the cutting efficiency.
Rivets and tabs are the components that connect these parts.
Saw chain classification
Saw chains generally distinguish between professional and non-professional, according to their kickback angle during the cutting process.
Professional saw chains have more rebound and are suitable for professional loggers or other people who use chain saws frequently.
Non-professional saw chains have less rebound and are suitable for household use.
No matter what kind of saw chain there will be rebound, you must pay attention to safety during use.
Saw chain selection
1. Pitch
The pitch is the center hole spacing of any three rivets on the saw chain divided by 2, generally divided into 1/4", 0.325", 3/8" profile (small 3/8"), 3/8" (large 3/8 "), 0.404".
2. The thickness of the middle guide tooth
The thickness of the middle guide tooth is the key dimension to cooperate with the guide plate, generally divided into 0.043", 0.050", 0.058", 0.063"
3. Saw chain length
The length of a saw chain is not its physical length, but the number of guide teeth in it.
In this way, the basic parameters of the chain can be determined.
Of course, the selection of the chain is also related to the shape of the cutter head. Generally, it is divided into rounded cutter head and right-angle cutter head. The cutting speed of the right-angle cutter head is fast, but it needs to be repaired frequently. Not to be dulled.
Generally, retailers will sell fixed-length chains. After confirming the above information, you can buy the chains you need from them.
