Do you know the 2 types of milling cutters commonly used in machining?

The milling cutter is a multi-tooth rotary tool, each tooth of which is equivalent to a turning tool fixed on the rotary surface of the milling cutter. When milling, the cutting edges that participate in cutting at the same time are longer, and there is no empty stroke, so the productivity is higher. There are many types of milling cutters with different structures and a wide range of applications, which can be divided into three categories according to their uses: milling cutters for processing planes, milling cutters for processing grooves, and milling cutters for processing forming surfaces. The general specifications of milling cutters have been standardized and are generally produced by professional tool factories. Now introduce 2 kinds of common milling cutters.

1、Face milling cutter

Face milling cutter, the main cutting edge is distributed on the cylindrical or conical surface, the end cutting edge is the secondary cutting edge, and the axis of the milling cutter is perpendicular to the machined surface. The face milling cutter is mainly used in vertical milling machines or horizontal milling machines to process the step surface and plane, especially suitable for the processing of larger planes, the main angle of the 90 ° face milling cutter can be milled at the bottom of the wider step surface.

Face milling cutter processing plane, while participating in the cutting of more teeth, and the vice cutting edge of the trimming effect, so that the processing surface roughness value is small, so you can use a larger cutting amount, higher productivity, widely used.

2、End Mills

An end mill is a common milling cutter in CNC milling, its structure, the cutting edge on the cylindrical surface is the main cutting edge, the end face is distributed with a secondary cutting edge, the main cutting edge is generally spiral teeth, which can increase the smoothness of cutting and improve machining accuracy.

Since there is no cutting edge at the core of the end face of the common end mill, the end mill cannot be axially fed when working, and the end face is mainly used to process the bottom plane perpendicular to the side. End mills are mainly used for machining recesses, step surfaces, and shaping surfaces with the use of leaning dies.

3. High-Speed Twist Bits

High-speed twist bits are a type of cutting tool commonly used in drilling operations. These bits are made from high-speed steel (HSS), which allows them to operate at faster speeds compared to traditional steel drills. The high-speed twist bit is characterized by its helical flute design, which helps to remove the material being cut efficiently, preventing the bit from binding during use. These tools are ideal for drilling holes in a variety of materials, including metals, plastics, and wood.

The high-speed twist bit works by rotating at a rapid pace, with the cutting edges on the spiral flutes doing the actual cutting. The helical design not only helps in clearing debris but also reduces friction between the cutting edges and the material. This makes high-speed twist bits suitable for both heavy-duty industrial applications and more delicate, precise work.

One of the significant advantages of high-speed twist bits is their durability. The high-speed steel composition ensures that these tools can withstand high temperatures, which is crucial when drilling into harder materials or at high speeds. They are widely used in CNC machines and manual drilling processes, as they provide a good balance between speed, precision, and cost-efficiency. Whether you're drilling metal, wood, or other materials, high-speed twist bits offer reliable performance for various applications.

4. Cutting Tools

Cutting tools are an essential part of any machining operation. These tools are used to remove material from a workpiece by shearing it off, and they come in many different shapes and sizes. Depending on the type of operation, cutting tools tools can be classified into several categories, such as drills, end mills, reamers, and turning tools.

Cutting tools like drills are used for creating round holes, while end mills are ideal for milling complex profiles. When selecting the right cutting tool, it's essential to consider the material being cut, the type of machining operation, and the required precision. In addition, cutting tools are typically made from materials like high-speed steel, carbide, or cobalt, each offering unique benefits depending on the application.

5. Straight Shank Twist Drill Set

A straight shank twist drill set is a collection of drills that feature a straight shank, making them compatible with more drill chucks. The straight shank design allows for easy installation and removal of the drill bit, making it an efficient choice for many drilling tasks. These sets typically come in various sizes, allowing users to choose the appropriate drill bit for their specific project needs.

Straight shank twist drills are designed with helical flutes that help remove material as the drill bit rotates, preventing clogging and ensuring smooth operation. The twist drill set is an essential tool in many machining operations, whether you're working with wood, plastic, or metal. Due to their versatility, these drills are commonly used in both industrial applications and small-scale workshops.
