Twist drill is a rotary cutting tool utilized for creating cylindrical holes in workpieces. Its name derives from the helical flutes that resemble the twisted shape of a hemp rope. The tool's main structure consists of the shank, neck, and working bod

Face milling cutters have cutting edges on both the end face perpendicular to the arbor and the outer circumference, and are mainly used for milling flat surfaces. The cutting edges on the outer circumference are the main cutting edges, while the cutting

In modern CNC machining centers, the tool holder plays an indispensable and critical role. It is the precision interface that connects the machine tool spindle to cutting tools (such as end mills, drills, and boring bars) and other accessory tools. Its pe

The bull nose end mill, a cornerstone tool in the vast and intricate domain of contemporary computer numerical control (CNC) machining and precision manufacturing, is fundamentally characterized by its distinctively engineered cutting edge geometry. Its d

Boring tool is a type of boring cutter, typically featuring a round shank, although larger workpieces may utilize square tool shanks. Its most common applications include internal hole machining, hole enlarging (counterboring), and profiling. It is a tool

CNC tool holder is the core component that connects the cutting tool to the CNC machine tool. Its precision directly affects the quality of the machining process, including accuracy, surface finish, and dimensional stability. The holder ensures the accura

Thread refers to the continuous protruding parts with a specific cross-section, shaped like a spiral, made on the surface of a cylindrical or conical parent body. Threads are classified based on the shape of the parent body into cylindrical threads and co

Tap is a tool used for cutting internal threads, featuring grooves along its axial direction. It is also referred to as a screw tap. Based on their shapes, taps are categorized into straight flute taps, spiral flute taps, and point taps (also known as tip

Traditional methods for thread machining primarily involve using single-point turning tools to cut threads on a lathe or employing taps and dies for manual threading and die-cutting. With the advancement of CNC machining technology, particularly the adven

AbstractIndexable inserts represent a cornerstone of modern manufacturing, a pivotal innovation in the field of metal cutting tools. These are polygonal cutting components mechanically clamped onto a tool holder or cutter body. Their defining characterist

A lathe tool is a cutting tool with a single cutting part, used for turning operations. It is one of the most widely used tools in machining. The working part of the lathe tool is the section that generates and handles chips, including structural elements

Cast iron is an iron-carbon alloy with a carbon content above 2.11%. Industrial cast iron generally has a carbon content of 2.5% to 3.5%. In cast iron, carbon mostly exists in the form of graphite, and sometimes in the form of cementite. In addition to ca
