The weight of the dismounted helical cutterhead.

What are the advantages of the discarded helical cutterhead as an innovative product for flat cutterheads that is rapidly taking over the market? Simply put the traditional flat cutterhead processing performance mainly depends on the sharpness of its flat blade and the contrast of the processing material, the spiral cutterhead is more scientific to evenly distribute the planing point to each processing blade, and at the same time the angle of the blade and the processing surface fine-tuning, it can be easily adjusted to adapt to the processing of different materials. The most direct difference between the two is the different cutting methods. The spiral cutterhead is segmented cutting, while the flat cutterhead is whole piece cutting. Segmented cutting can make the unit time cutting contact area is small, and therefore less resistance, less friction. Advantages are low heat generated by cutting, low noise, long blade life, power saving, smooth and delicate cutting surface. As the cutterhead is spiral design, it is more conducive to chip removal and cutterhead maintenance. The traditional flat cutter head is the opposite of the above, so the rise of the discarded spiral cutter head is inevitable.

The abandonment spiral cutter head is divided into heavy cutting and light cutting mainly because the installation of the blade is not the same. Planing edge cutting angle is also the direction of the blade cutting edge line and planing table planing mouth line between the angle is the most important parameter is not easy to find, according to planing edge cutting angle points, spiral planer knife is divided into heavy cutting spiral planer knife and light cutting spiral planer knife. The difference between these two cutting methods also determines the quality and price of spiral planer knives. Compared with the light-cutting spiral cutter shaft, the heavy-cutting resistance is small, the noise is small, the quality of planing is high, the manufacturing process is more complicated, naturally the cost is higher, under certain circumstances, the number of grooves is the more the better, the arrangement of blades is also the more the better, the higher the quality of planing. Heavy cutting spiral cutter head is mainly used in automatic copy milling planer, vertical shaft machine, four-sided planer and other cutting and shaping. And the light cutting spiral cutter head is mainly used in vertical shaft machine, four-sided planer and other main cutting plane smooth and round.

The blade is a very important helper for both heavy and light cutting heads, so the spiral cutter shaft requires special attention when using or replacing the blade:

One. To change a cutting edge, rotate the blade 90° after scrubbing it clean. Note: There is a marking point on the surface of the blade to ensure the same orientation, to avoid the old and new cutting edges to change the wrong.
Two, gently press the blade, slide a few times, spiral knife, so that the bottom surface of the blade and the knife seat fit, clockwise locking screw, the blade will automatically be pressed against the knife seat positioning table. (Note: In order to ensure that the screw and the screw hole will not bite, rust, flat planer spiral knife, to avoid the next time is not easy to loosen, change the blade screws need to dip a little oil lubrication).
Three.Check carefully whether the blade is placed correctly on the knife seat, to avoid locking the blade when the blade is broken or the cutting surface is ribbed.
Four, check the blade before use, woodworking spiral knife, if broken, please be sure to replace it immediately, so as to avoid causing safety accidents and damage to the product, and often check the screws to avoid screw loosening.
