Cutting tools weekly

Reducing CO2 greenhouse gas emissions has become the goal of the world, and now many places are discussing to levy CO2 emission tax. Due to the emergence of new fields, and people have to adapt to the existing fields, the…

If you don’t have a lot of experience in metalworking, you may not be familiar with this type of metal forming. How does it work and when do we use it? What is a turret punch? Turret punch, also known…

Cemented carbide has the edge of high hardness, good wear resistance, corrosion resistance and a small coefficient of thermal expansion. It is widely used in the manufacture of precision molds such as optical glass forming, metal drawing, and wear-resistant and corrosion-resistant…

High precision CNC lathe paired with advanced cutting tool provides us with superior material removal rate and productivity. As the connector between lathe and cutting tools, tool handle plays an important role in obtaining desired results. So how to choose…

As is well known to us, tipped cutting tools can be grouped into solid tool, brazed tool, tool with mechanical clamp, and tool with indexable tips on basis of methods to inlay tips on the tools. We herein discuss which makes up indexable inserts the…

The systematic mechanical related deviation of machine tool can be recorded by the system, but due to environmental factors such as temperature or mechanical load, the deviation may still appear or increase in the subsequent use process. In these cases,…

Broadly used in holes processing, boring bars are usually used to broach holes that have already been preliminarily drilled and improve hole diameter accuracy. They have solid shanks and coolant holes. Familiar with long overhang machining, you probably get haunted by an…

We are aware of that surface roughness means a lot in manufacturing industry. When the concept is recalled to your mind, there must be some common textures on machined parts, such as bright mirror surface, matte, and dull polish. They…

Tool surface coating technology is a surface modification technology developed in response to market demand. Since its appearance in the 1960s, this technology has been widely used in the metal cutting tool manufacturing industry. Especially after the emergence of high-speed…

Cause of wear on Cutting tool include the following ones: Cutting tool materials Tool material is the fundamental factor to determine the cutting performance of the tool, which has a great influence on the machining efficiency, machining quality, machining cost…

Burr in metal processing is a common problem, such as drilling, turning, milling, plate cutting. One of the hazards of burrs is easy to be hurt. In order to remove burrs, a second operation called deburring is usually required. Three deburring…

If you ask, “What’s the difference between CNC machining and 3D printing?” The most straightforward answer: 3D printing is an augmentation technology, CNC machining is a reduction technology. 1. Material differences The main materials for 3D printing are liquid resin…

Deep-hole drills are often divided into external chip removal (also known as gun drill), internal chip removal (often abbreviated as BTA by the International Association of Deep-hole Drilling), nesting or spraying chip removal. This paper mainly introduces the development and…
