How to choose a blade for a chipper?

In wood chipping machines, the blade is more easily damaged, and the lifespan of the blade is also a concern for users. Therefore, it is important to choose a good set of cutting tools for the chipping machine.

In general, the blade of the chipping machine is made of alloy steel and undergoes professional heat treatment. The hardness of the blade is between HRC55-58 °. It is necessary to ensure that the blade is sharp and wear-resistant for a long time to ensure the quality and production efficiency of cutting wood chips.

The thickness of the blade can be controlled between 2-20mm, with a sharp edge and good crushing effect. The surface is as beautiful and tidy as a mirror, with wear resistance, uniform hardness, flat cut, good stability, and a continuous production time that is twice the average lifespan of peers.

Increase blade thickness and angle to prevent blade deviation, effectively transmit cutting force, and design blades of various shapes to meet the needs of different customers.

The alloy cutting tools of the chipping machine are wear-resistant, reliable, advanced, and improve their service life - the unique design of the crushing system greatly improves the service life of the equipment. The crushing chamber adopts a multi-stage crushing process and a fine crushing principle device, which is characterized by high working impact, high production efficiency, and strong fine crushing ability.

The sharpness of the cutting tool of the chipping machine directly affects the quality of the chipping. There are two types of flying knife blades: single blade and double blade, and drum chipper strip bottom blades mostly use four sided blades. When cutting with a single blade, it is easy to cut the raw material into pieces; Double edged blades are suitable for cutting hard and frozen materials. The grinding angle of the blade should be determined based on the material being cut. When cutting hard or frozen materials, the grinding angle should be large, while the grinding angle of the tool for cutting soft materials should be small. This can ensure good cutting quality and reduce energy consumption. To ensure the sharp edge of the blade, it is required to regularly grind and replace the blade. Under normal circumstances, the flying blade should be replaced and ground every 4-8 hours, and the bottom blade should be replaced every half a month.

The toughness of different types of wood varies, and the difficulty of cutting also varies. At this time, the selection of blades for chipping machines becomes very important. In general, blades made of alloy steel are used, which have the advantage of high hardness. However, with longer cutting time, they are prone to damage, and their service life is not very long. Therefore, it is necessary to be cautious in the selection of blades, and try to choose blades that have undergone high-density heat treatment and have a long service life. This not only improves the overall service life of the machine, but also improves the overall service life, It is also a good choice for oneself.
