What are the advantages of woodworking spiral cutter head?

With the development of science and technology, the discarded spiral head for woodworking has gradually replaced the traditional flat knife, four side planer, and in the near future, the discarded spiral head will be gradually popularized in the woodworking machinery industry. As an innovative product of flat knife and four side planer, the design of discarded spiral cutter head has become the standard tool for woodworking machinery in Europe and America.

The discarding spiral cutter head distributes the planing points to each processing blade more scientifically, and finely adjusts the angle between the blade and the processing surface, which can be easily adjusted to adapt to the processing of different materials.

Discarded spiral cutter head


  • Spiral cutting surface: high precision design and manufacturing technology, the discarded blades are reasonably arranged around the cutter body to form a smaller cutting surface in unit time, so as to improve the blade burning mark and the berm.
  • Fast heat dissipation speed: some cutter bodies are made of 7 Series aerospace-grade aluminum alloy, which not only improves the heat dissipation speed but also improves the stability and structural strength of the cutter body, thus improving the service life of the cutter body.
  • Discarded blade: the imported Luxemburg small blade is adopted, and the assembly method without high-temperature welding ensures that the original hardness of each blade is above hra93.5 degrees, which greatly improves the service life of the tool. When the blade is passivated, the factory operator can remove the blade by himself, which is easy to operate and saves time.
  • Long service life: the service life of the aluminum alloy cutter body is 1-2 times longer than that of the ordinary flat cutter, and 3-4 times longer than that of the double-face planer and the four-face planer.
  • Sawdust is very small: the sawdust formed by a spiral cutting in unit time is very small, so it is easy to discharge the sawdust from the processed wood surface in the Sino British dust collection system.
  • Low noise: the noise value generated by contacting the wood surface in unit time and contacting the wood surface in the same time with the flat knife will be reduced by 30 to 50dB.
  • Discard type spiral cutter head is divided into: heavy cutting spiral cutter head and light cutting spiral cutter head. Heavy cutting spiral cutter head is mainly used for automatic copying milling machine, vertical shaft machine, four side planer, cutting molding. The light-cutting spiral cutter head is mainly used for vertical shaft machine, four side planer, etc., and the main cutting plane is smooth and round.

How to replace an ordinary planer with a spiral cutter shaft?

  • Check whether the original bearing meets the accuracy requirements, and it is recommended to replace the new bearing. The bearings to be replaced shall be P5-grade bearings with low noise and high precision.
  • Check the inner diameter of the bearing pedestal (the inner bore of the bearing has been worn out for many years, which will cause a lot of noise and damage the bearing in a short time, and make the bearing go to the inner or outer circle). If there is a problem with the bearing pedestal, it must be replaced with a new one.
  • Check and clean the shaft head and seat before installing the bearing; Add 3 × white grease into the bearing; When installing the bearing, it is required to press the bearing in smoothly and evenly (if there is hydraulic equipment, please use hydraulic equipment to install the bearing, if there is no hydraulic equipment, steel sleeve should be used to contact the inner ring of the bearing to knock in evenly, so as to avoid damaging the outer circle of the shaft head by knocking on one side).
  • There are four cutting-edge surfaces. If one cutting edge of the blade is blunt, it is necessary to tighten the screw anticlockwise to clean the tool holder and blade. It is recommended to use gasoline or Tianna water to clean it easily; When changing the cutting edge, we must pay attention to: each blade has a mark on the surface, and we must ensure the uniform orientation, so as to avoid uneven wood cutting surface caused by the wrong replacement of the new and old cutting edge.
  • If the screw is too tight or rusty, it is difficult to loosen it. First, put the bit into the plum blossom mouth of the screw, and tap it gently with a small hammer (pay attention not to damage the blade), and then it is easy to loosen it with a wrench; To avoid the phenomenon that the screw is rusty and hard to loosen when changing the blade next time, it is recommended that the screw hole must be cleaned every time when changing the blade, and then the screw can be dipped with oil and then screwed into the screw hole so that the screw can be easily loosened when changing the blade next time.
