The next step is to consider the tool selection cutting materials

The next step is to consider the tool selection cutting materials. The most common cutting materials in the metal processing industry can be divided into two categories: non-ferrous and ferrous materials. Non-ferrous materials including aluminum and aluminum alloy, copper and copper alloys, magnesium alloys, nickel and nickel alloys, titanium and titanium alloys. Ordinary ferrous materials including carbon steel, alloy steel, stainless steel, tool steel and iron casting materials such as cast iron. Non-ferrous metal is relatively soft, easy to cut, but other than nickel and titanium. Ferrous metals are usually hard and difficult to cut.

Tool selection, tool material is the most important factor to consider. The majority of these tools are three basic materials: high-speed steel, carbide and carbide cog. Almost all of these basic tool material can be used for cutting of various materials. The only difference in performance. The hardness of high speed steel cutting tools is very high, but poor wear resistance. The carbide wear resistance is very good, but easy to break. Carbide cutting material suitable for use in high speed and feed rate, but the price is more expensive. Carbide cog tool is very suitable for mass production applications because each cog has a plurality of cutting edges. A cutting edge wear, you can be divided into degrees to another cutting edge have been used in all cutting edge, simply replace the cog, rather than the entire tool.grinding disc

Tip: If you are using a high-speed steel drills, you must first use the center drill. Then drilling. This ensures that the correct location of the borehole. If you are using a carbide drill first drill center, carbide drill with their own pair nose. If you use a carbide drill drilling has been executed the center hole drilling process will damage the drill. Outer cutting edge in contact with the conical wall before the drill began cutting. This external impact cutting edge and lead drill fragmentation. Carbide drill must first begin cutting from the tip, and then use the outer cutting edge.abrasive tools
