3 Specifications. Saw chain parameters mainly include pitch, middle guide tooth thickness, and cutter tooth shape.
1. Pitch: The pitch of the saw chain is the distance between 3 rivets dao divided by 2; it corresponds to the pitch of the sprocket. Including 1/4, 0.325, small 3/8, large 3/8, 0.404 (unit is inches; 1 inch = 25.4mm).
2. The thickness of the middle guide tooth: corresponding to the width of the guide groove of the guide plate. Including 0.043, 0.050, 0.058, 0.063 (in inches; 1 inch = 25.4mm).
3. The shape of the cutter teeth: determines the smoothness of the cut wood. Including rounded corners, right angles, and arcs.
Chain saw, also known as chain saw, is a portable saw powered by a gasoline engine. It is mainly used for logging and lumbering. Its working principle is to cut through the transverse movement of the interlaced L-shaped blades on the saw chain. Chain saws are generally divided into motorized chain saws, non-motorized chain saws and so on.
Chain saws are divided into different sources according to the same reason: gasoline saws, electric saws, pneumatic saws, and hydraulic saws. The advantages and disadvantages of these four power chain saws are obvious:
Gasoline saw: highly mobile, suitable for mobile work in the field. However, it is noisy, troublesome in maintenance, and generates more heat.
Electric chain saw: stable power, quick start, heavier than other saws. But if the line is too long, it will be inconvenient to move.
Pneumatic chain saw: safe and pollution-free, low noise, light weight. However, an air compressor must be attached, which increases the floor area and is restricted by conditions.
Hydraulic chain saw: full power, but slow start, stable work. The hydraulic pump station has a smaller volume than an air compressor. higher cost.
