What types of cutting tools do milling machines have?

Milling machine cutters include cylindrical milling cutters, face milling cutters, end milling cutters, three sided edge milling cutters, angle milling cutters, and saw blade milling cutters. 1. Cylindrical milling cutter Used for machining flat surfaces on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter and are divided into two types according to tooth shape: straight teeth and spiral teeth. According to the number of teeth, there are two types: coarse teeth and fine teeth. The spiral tooth coarse tooth milling cutter has a small number of teeth, high tooth strength, and large chip holding space, making it suitable for rough machining; Fine tooth milling cutters are suitable for precision machining. 2. Face milling cutter Used for vertical milling machines, end face milling machines, gantry milling machines, and upper machining flat surfaces. There are cutter teeth on the end face and circumference, as well as coarse and fine teeth. There are three types of structures: integral, toothed, and indexable. 3. End milling cutter Used for machining grooves, step surfaces, etc. The cutter teeth are on the circumference and end face, and cannot feed along the axial direction during operation. When there are end teeth passing through the center on the end milling cutter, it can be fed axially (usually referred to as a "keyway milling cutter" for double edge end milling cutters).

How to choose alloy milling cutter correctly

The milling cutter made of cemented carbide is called cemented carbide milling cutter. Cemented carbide is a powder metallurgical product made of high-hardness, refractory metal carbide micron powder as the main component; cobalt or nickel as a binder and sintered in a vacuum furnace or a hydrogen reduction furnace.

What types of end mills are there?

There are many types and shapes of end mills. It comes in many types, including flat end milling cutters, ball end milling cutters, flat end milling cutters with chamfers, forming milling cutters, chamfering cutters, T-shaped cutters, toothed cutters, and rough leather cutters. Among them, flat end milling cutters can be used for rough milling. Their main function is to remove a large number of blanks, as well as small horizontal planes or fine milling of contours; And for semi precision milling and precision milling of curved surfaces, there are ball end milling cutters, which can precision milling steep surfaces and small chamfers on straight walls; A flat end milling cutter with chamfers can be used for rough milling to remove a large number of blanks, which can precisely mill small chamfers on fine flat surfaces. It also includes chamfering cutters; There is another name for T-shaped knife, called drum shaped knife or toothed knife; The shape of the forming milling cutter chamfer cutter is the same as the chamfer shape; Chamfer cutters are divided into milling cutters for circular chamfering and oblique chamfering. T-shaped cutters can mill T-shaped grooves, while tooth shaped cutters can mill various tooth shapes. There is also a rough milling cutter specifically designed for aluminum copper alloy cutting, which can perform rapid machining.

What are the structural characteristics of end mills?

End milling cutter is a widely used multi blade tool in CNC machining, which can process flat surfaces, step surfaces, grooves, etc. The milling speed of the end mill is high and there is no clearance, so it is a high-efficiency cutting tool. The geometric structure of a milling cutter is very complex, and the overall structure of an end milling cutter can be divided into three parts: the blade, neck, and shank. The blade is the most important part of the entire cutting tool, and its material, shape, and number of teeth determine its machining performance. The cutting edge on the cylindrical surface of the end mill is the main cutting edge, and the secondary cutting edges are distributed on the end face; The handle is the clamping part of the cutting tool, which is used to connect with the machine tool and transmit torque during milling. Its shape determines the size of the blade diameter; The neck is the part that connects the blade and the handle. The blade is the most complex part of an end mill, therefore, the key to 3D modeling of an end mill is to model the blade. The main structure of the blade is a spiral entity, which can be obtained by scanning and cutting the generated cylinder with the vertical section of the spiral groove as the contour and the combination curve of the spiral line and a tangent line as the path, forming a spiral entity. The shank of end mills is generally divided into two categories: straight shank and tapered shank. The positioning and installation of straight shank end mills are relatively convenient. For small diameter end mills, the straight shank type is widely used.
