Chainsaw guide and saw chain can be compared to the image of the train and the guide rail, the train bumps run and accurately arrive at the destination, relying on the support and guidance of the guide rail; similarly, the chain bumps high-speed movement along the straight line, but also rely on the support and guidance of the guide plate. So, how is the support and guidance function of the guide plate realized? First of all, we know that the shape of the guide plate is thin plate, long, its two front are guide rail through the end of the first, the width of the guide rail size requirements to complete the chain support and positioning; In addition, the straightness of the guide rail also has a strict standard, so that the chain can be along the guide to stop the straight-line movement.

The saw chain and guide plate both "collaborate" with each other to complete the chain saw saw cutting operations. Next, we understand that the two correspond to the size of those parameters. The following about the guide plate and saw chain corresponding parameters, stop one by one description: 1, the guide plate guide width (corresponding to the saw chain in the guide tooth thickness) (unit: inches; 1 inch = 2.54 centimeters): divided into 0.043, 0.050, 0.058, 0.063, etc..  2, guide plate guide wheel tooth pitch (corresponding to the pitch of the saw chain) (unit: inches): divided into 1/4, 0.325, 1/4, 3/8, 0.404 and so on.

For example, 5200 and 5800 chain saws use a guide plate with a guide width of 0.058 inches and a guide wheel tooth pitch of 0.325 inches. Chainsaw guide plate other dimensional parameters also include the depth of the guide rail, the guide plate end of the opening tooth width and length, the location and size of the oil filling holes, the location and size of the positioning holes, etc., all need to correspond to the installation components of the chainsaw. The guide plate is mostly made of 65 manganese steel, 50 manganese steel work material, 65 manganese steel material guide plate is better. There are many brands of guide plates, including Stihl, Oregon, Husqvarna, Senwart and dozens of other brands.
