Metal processing is inseparable from the blade. A good blade must have high wear resistance, long tool life, high metal removal rate and high reliability. It is even required to have high performance in dry cutting or wet cutting under severe conditions (such as complex cutting and deep cavity), so as to ensure small tolerance of workpiece size and excellent surface quality. Today, let’s take a look at how the leader of the blade industry produces blades<\/p>\n\n\n\n

How to make blade tolerance accurate<\/h2>\n\n\n\n

A typical blade is made of 80% tungsten carbide and metal matrix. The function of metal matrix is to bond hard cemented carbide powder together, of which cobalt is the most common. The process of producing blades is very complex. It takes more than two days to complete, and there will be a lot of challenges. In addition to absolute precision and reliability, cleanliness is a prerequisite. The whole process must be well guaranteed without any carelessness.<\/p>\n\n\n\n

This is a key step in the manufacturing process. The use of 6-axis grinder can ensure very strict tolerance, so that there has been a joke in Kimmer factory: “if you sneeze, the tolerance will change immediately”.<\/p>\n\n\n\n

Clean and coat the blade immediately after grinding. To avoid any grease or dust, gloves must be worn when taking the blade. There are two different coating methods of blade coating: chemical vapor deposition (CVD) and physical vapor deposition (PVD). In a typical CVD, the blade substrate is contacted with one or more volatile coating gases, which react on the surface of the blade substrate to generate the required deposits.
