Basic Knowledge of CNC Cutting Tool

Posted on November 12 2012 by There are two major lines in the ceramic tool materials, namely alumina-based and silicon nitride department. Ceramics, as a cutting tool, have the advantages of low cost, high hardness, high temperature performance and a good prospect. in CNC cutting tool, carbide end mills

Commonly Used Material of CNC Tools

Materials CNC tool is broadly divided into the following categories: high-speed steel, carbide, cermet, ceramic, polycrystalline cubic boron nitride, and polycrystalline diamond. Here mainly mention the ceramic, the time of the use of ceramics for the cutting tool is earlier than carbide, but due to their brittleness, the development is very slow. But since the 1970s, it still gets a relatively fast development. There are two major lines in the ceramic tool materials, namely alumina-based and silicon nitride department. Ceramics, as a cutting tool, have the advantages of low cost, high hardness, high temperature performance and a good prospect.

Category of CNC Cutting Tool

According to cutting exercise and the blade shape, CNC cutting tool can be divided into three categories. The general-purpose tool, such as turning tools, planer, milling cutters (excluding forming lathe tool, shaping the planer and forming cutter), boring tools, drill bits, reamers, reamers and saws, etc.; the forming tool, this type of tool blade has the same or nearly the same shape with the workpiece cross section, such as forming turning tools, molding planer, shaping cutters, broaches, tapered reamer and threaded processing tool; The generating tool is to use the generating method to process gear tooth surface or similar artifacts, such as hobs, shaper cutters, gear shaving cutters, bevel gear planer and bevel gear milling cutter. Cutting tools, if classified in the form of the workpiece surface, can be divided into five categories. Cutting tools used to process a variety of the outer surface are including turning tools, planer, milling, outer surface pull knife and rasp; hole-making tools, including drills, reamers, boring tool, reamer and the inner surface of the broach; the thread processing tools, including taps, dies, thread cutting head automatically opening and closing, thread turning and thread milling cutters, etc.; and the gear cutting tools, including hobs, shaper knife, shaving cutter, bevel gear processing tool; the cutting tool, including inserts tooth circular saw blades, band saw, bow saw, cut off lathe tool and blade cutter.

Alloy End Mills



The carbide end mills are the milling cutter made with carbide material. If you want to learn carbide cutters then you need to know what the cemented carbide is. Cemented carbide is based on the high hardness micron level refractory metal carbide (WC, TiC) powder as a main component, and powder metallurgy products uses cobalt (Co) or nickel (Ni), molybdenum (Mo) as a binder, fired in a vacuum oven or hydrogen reduction furnace. Carbide cutter is mainly divided into: solid carbide tools, carbide straight shank slot cutters, carbide blade cutter, carbide spiral drill cutter, carbide machine reamer cutter, carbide end mill and carbide ball end mill.
