The milling cutter is often made of hard, strong material that can withstand significant stress without breaking or otherwise suicide to damage. Since the milling cutter rotates against a stationary workpiece, it ejects the material. Operations commissioned using a lathe typically feature a single-blade cutting tool, with milling cutters having multiple blades. According to that saying, milling cutters do not have a single blade. The purpose of milling cutters is to remove material from a workpiece. Face mills are ideal in various cases, but it is expensive, while fly cutters are very inexpensive.Īlso, Read: How Do Drum Brakes Work? | Working of Drum Brakes | Type of Drum Brakes Overview of Milling Cutters: As the entire unit rotates, the tool bits take wider, shallow cuts. A fly cutter is made of a body into which one or two tool bits are inserted. It is a cutting tool that transits and rotates with the argon of a lathe and acts on the work fed into its circular path. It is also used to cut three-dimensional shapes. It is used to reduce the concentration of stress. Ball cutters as their end are hemispherical in shape. The dovetail cutter is a final mill whose form protrudes behind a dovetail slot. It is cylindrical in shape with helical bite teeth. It is also a cutting tool that is used to cut teeth. The cutting process enables the productions of threads with a multi-profile from M2 to a nominal diameter of 1 mm (single profile). The thread is produced by a helical projectile. Teeth come in both straight & staggered varieties. It is slightly hollow at the edges for relief, and the teeth are not side cuttings. This tool is used to cut keyways for a wooden key. The bites of hollow surfaces are on the inside surfaces. It resembles a pipe that has thick walls. Cylindrical Milling CutterĪ cylindrical mill cutter is a type of Cutter that has a cylindrical shape and has teeth only on the perimeter surface. The form cutter is designed to have a specific shape on the workpiece.Ī concave milling cutter is a type of Cutter shaped to match a convex surface of a circular contour equal to half a circle or less. Concave Milling CutterĪ concave cutter is a type of formed Cutter. Staggered mill cutters are staggered at the periphery with optional right and left-hand helix angles and are made to a relatively narrow width. It is the type of Cutter in which peripheral milling cutters of different sizes are cut together to remove material from the workpiece simultaneously.

The face mill cutter is very rigid, and the surface finish depends on the feed rate and the number of teeth. The diameter of the cutter body depends on the length of the workpiece and the available clearance on either side of the workpiece.įace mill cutters are used in down milling. A large amount of material is removed by making radially deep and axially narrow cuts. Face Milling Cutterįace mill cutters have a large diameter cutter body with several mechanically fastened insertion tools. It is also used to cut slots and mix deep and narrow slots. This Cutter is mostly used in strand milling operations and face milling operations. Side Milling CutterĪ side mill cutter is a type of Cutter in which the cutting teeth are present on the periphery and also on the face or end. Perimeter mill cutters can only be used for horizontal mill machines. When the cuttings’ teeth are present on the circumference of the circular disc, it is known as a circumference mill cutter. These cutters make very small chips that result in a rough surface finish. As the names themselves suggest, it is used to extract large amounts of material. These cutters give a great performance under the toughest operating conditions. Roughing mills are also known as “Pippa” cutters. The first one is known as centers cutting, which has cutting edges on both sides of the Cutter, and the second one is a non-center cutting edge with the cutting edge on only one side. This Cutter is mainly available in two variants. It is made of high-speed steel or hardened material. This Cutter consists of one or more flutes and is ultimately used in milling operations. The basic difference between a drill bit and an end mill cutter is that the drill bit can only cut in the axial directions, but this Cutter can cut in all directions. The term “end mill” is commonly used for flat bottom cutters. It has teeth on either side, so it can be used very successfully in drilling operations.
