The planer is a woodworking tool used to plane the surface, as shown in the picture. It is fastened to the rotating tool bar and is often used to planer the coniferous pine wood with a margin of 2 to 3 mm. Blade rotation speed is very high (2400 ~ 2500 RPM), each of the cutting quantity of 2 ~ 3 mm, coupled with the sudden increase in load, in part so that the blade was very shock, especially when encountering the \"knot\", this kind of impact force is worse, even a blade part dozen a (form a gap). This requires a high strength, toughness, and proper hardness, as well as a precise size and shape of the planer.

     Woodworking cutter is a special plane cutting blades, wood processing products for woodworking planer, woodworking cutter material is roughly divided into three categories: (TCT) carbide woodworking planer knives, high speed steel (HSS) (feng steel) woodworking planer knives, low alloy tool steel (Cr12MoV, 9 crsi, manganese steel and high carbon steel production of woodworking planer tool cost is low, use value is not high. The recommended wood planer is HSS high speed steel, i.e.

【 material 】According to the working characteristics of the planer, W6Mo5Cr4V2 high-speed steel was selected as the material of the planer, and the reasonable heat treatment was carried out, which greatly improved its service performance and extended its life.
1: TCT woodworking planer, namely hardmetal woodworking planer. The shaper cutter with this material has a long life and is of high value to the planing of hard miscellaneous wood. But not easy to sharpen the blade, and more expensive Pleiades. It is of little value to planing such as pine.
2: HSS high speed steel woodworking planer, commonly known as front steel. The usual materials used are W6Mo5Cr4V2 (6542), M2, etc. High speed steel woodworking planer has all steel blade, insert steel blade, the suitable blade for use is insert blade steel blade, sharp edge and easy to grind knife edge, not easy to break qianfeng steel without this advantage.
3: woodworking planer of low alloy tool steel, i.e., Cr12MoV, 9CrSi, etc. The blades are cheap and have sharp edges. Easy to sharpen the blade, suitable for pine type planing. A kind of miscellaneous wood is vulnerable to damage quickly.
Use and maintenance of woodworking planer:
Woodworking planer is a blade for rotary machine. When using, please pay attention to the contact between finger and blade. After the operation is completed, the residual material in the cover should be cleaned. The cutting edge of the planer should be operated on the grinder. Do not grind the blade on the surface grinding machine without fixture.

\"Installation\"First cutter grinding flat, put the every the planing tool into card slot, blade appear a bit longer, keep axis can rotate, the screw to the eighth tight, with straightedge lie in a panel, after planer tiejin panel, straight edge end on the plane mouth, reverse rotation axis, if the blade is higher than the panel, with wooden hammer knock blade, both end and middle points three adjustment, until every three o 'clock the incision just grazed ruler, one to the height of the blade and tablet, tighten the screws.
