Keep your wood edger blades sharp!

Wood edge milling takes place immediately after the log is debarked and inspected by a metal detector. It could even be called the first stage of wood processing. After this stage, you receive two different raw materials for the production of products. The quality of the milling cutter blades and their wear play a key role in ensuring the efficiency of this process, so keep your wood edge milling cutter blades sharp!

The first signs that the blades are worn out

Wood chips and milled boards are the main products of this stage, which are transferred to further processing stages, such as chemical pulp, boards, timber, wood products and other products. When it comes to the efficiency of the mill, you should know that the quality of the boards decreases as the degree of wear of the knives increases. Another negative aspect of blade wear is the increase in energy consumption. Therefore, the first thing that will indicate inefficient operation is the quality of the wood chips and electricity consumption.

What causes knife wear?

Although wood is classified as a fairly soft material that is easy to handle, it is and remains a heterogeneous material whose resistance is caused by changes in mechanical force. Uneven resistance is caused by various factors, such as branches and knots, which are significantly harder than other parts of the tree. Therefore, as soon as the blade reaches such a knot, it receives a large impact. Each species and type of tree affects the service life of the parts differently, as each tree contains different chemicals that can create corrosive conditions and abrasive particles that cause the blades to wear out during the process.

The key is to take care of your equipment in a timely manner and choose a hardwood that matches the capacity and performance of the equipment. This way you will avoid producing poor quality products, dissatisfied customers, increased energy consumption, or even costly downtime due to equipment damage.
