Let's first discuss the classification of milling cutters:
1. Cylindrical Milling Cutters: Used for machining planes on horizontal milling machines. The teeth are distributed on the circumference of the cutter, and are classified by tooth shape into straight teeth and... There are two types of spiral milling cutters. They are classified by the number of teeth: coarse and fine. Coarse spiral milling cutters have fewer teeth, higher tooth strength, and a larger chip space, making them suitable for roughing; fine spiral milling cutters are suitable for finishing. 2. Face milling cutters, also known as disc milling cutters, are used on vertical milling machines, end milling machines, or gantry milling machines to machine flat surfaces. They have teeth on both the end face and circumference, and are also available in coarse and fine tooth configurations. Their structures include integral, insert, and indexable types. 3. End mills are used to machine grooves and stepped surfaces. The teeth are on the circumference and end face, and they cannot feed axially during operation. When the end mill has a center-passing end tooth, axial feed is possible. 4. Three-sided milling cutters are used to machine various grooves and stepped surfaces. They have teeth on both sides and the circumference. All have cutting teeth.
5. Angle end mills: Used for milling grooves at a certain angle. There are single-angle and double-angle end mills.
6. Saw blade end mills: Used for machining deep grooves and cutting off workpieces. They have many cutting teeth on their circumference. To reduce friction during milling, the cutting teeth have a secondary cutting edge angle of 15′~1° on both sides. In addition, there are keyway end mills, dovetail end mills, T-slot end mills, and various form end mills.
7. T-slot end mills: Used for milling T-slots.
By product structure:
1. Integral type: The cutter body and cutting teeth are made as one piece.
2. Integral brazed tooth type: The cutting teeth are made of cemented carbide or other wear-resistant tool materials and brazed onto the cutter body.
3. Inserted tooth type: The cutting teeth are mechanically clamped to the cutter body. These replaceable cutting edges can be made of solid tool material or welded tool material. Milling cutters with the cutting edge mounted on the cutter body and sharpened are called internally sharpened cutters; those with the cutting edge sharpened separately on a fixture are called externally sharpened cutters. 4. Indexable Type: Indexable cutters are widely used in face mills, end mills, and three-sided milling cutters.
About Milling Broadcast: To understand milling cutters, you must first understand milling knowledge. When optimizing milling results, the cutting inserts are another important factor. Having more than one insert participating in cutting simultaneously in any single milling operation is advantageous, but having too many inserts simultaneously is a disadvantage. During cutting, each cutting edge cannot cut simultaneously. The required power is related to the number of cutting edges involved in the cutting. The position of the end mill relative to the workpiece plays a crucial role in chip formation, cutting edge load, and machining results. In face milling, using an end mill with a width approximately 30% larger than the cutting width and positioning it close to the center of the workpiece results in minimal variation in chip thickness. The chip thickness at the entry and exit points is slightly thinner than that during center cutting. To ensure a sufficiently high average chip thickness/feed per tooth, the appropriate number of teeth on the end mill must be correctly determined for the operation. The tooth pitch of the end mill is the distance between the effective cutting edges. End mills can be classified into three types based on this value-close-tooth end mills, wide-tooth end mills, and... High-precision milling cutters. The principal cutting edge angle of face milling cutters is also related to the chip thickness. The principal cutting edge angle is the angle between the main cutting edge of the insert and the workpiece surface. Common types include 45-degree, 90-degree, and round inserts. The direction of the cutting force varies significantly with the principal cutting edge angle: a 90-degree cutter primarily generates radial force, acting in the feed direction. This means the machined surface will not bear excessive pressure, making it more reliable for milling workpieces with weak structures. A 45-degree cutter has roughly equal radial and axial cutting forces, resulting in more balanced pressure and lower machine tool power requirements. It is particularly suitable for milling short-chip materials that produce fracturing chips. Components. Circular insert milling cutters mean that the principal cutting edge angle changes continuously from 0 to 90 degrees, primarily depending on the depth of cut. These inserts have very high cutting edge strength, and because the chips produced along the long cutting edge are relatively thin, they are suitable for large feed rates. The direction of the cutting force along the radial direction of the insert constantly changes, and the pressure generated during machining depends on the depth of cut. Modern insert geometry has given circular inserts advantages such as smooth cutting performance, lower machine tool power requirements, and good stability. It is no longer just an effective roughing cutter, but is widely used in face milling and end milling.
