The precious gems of manufacturing machines, cutting tools, are indispensable. Global demand for metal cutting tools is increasing.

The flexibility of cutting tools make it simpler and faster to complete different tasks. However, there are several kinds of cutting tools available on the marketplace, all designed for a specific purpose.

People often get confused among various cutting tools. It is certainly difficult to pick the appropriate solid cbn inserts manufacturers to machine the parts. This article will explain the distinctions between different kinds of cutting tools and how to pick the most appropriate one for your particular cutting operation.

Let's look at the cutting tools in more detail!

What is a cutting tool?

Cutting tools are sharp, wedge-shaped tool that is used to remove or cut materials for shaping or manufacturing parts. They are typically made from toughened tools that can be used in a variety of materials, and feature unique designs. The velocity of the cutting tool and workpiece is responsible for the cutting process. Tools for cutting are usually designed to cut metals but are also used for different functions.

Cutting tools are connected to various machines to provide a variety of cutting operations, including drilling, turning milling, and others. There are many geometries you can use to design cutting tools such as solid cbn inserts for hard turning with different clearance angles.

The classification of cutting tools is based on Material

There are many materials that are machined and cut within the manufacturing industry. Different cutting tools are utilized for each specific material, with distinct properties for efficient cutting. Below is an inventory of cutting tools based on their properties and composition.

Carbon steel tool

High-speed steel tool

Cemented carbide tool

Ceramics tool

Cubic Boron Nitride Tool

Diamond Tool

1. Carbon Steel Tool

For companies that need to perform low-speed machining operations carbon steel cutting tools are a great option. They typically have 0.6 to 1.5 percent carbon and 0.5% Mn. Moreover, Cr and V can increase the hardness of the cutting tools as well as the size of the grains.

Carbon tool steel is usually not recommended for modern machining processes. It is not able to withstand higher temperatures (more than 250°C).

It is possible to find the use of this material in milling tools, twist drills, and forming tools to cut soft materials likemagnesium or brass.

2. High-Speed Steel (HSS) Tool

High-speed steel tools are made up of many alloying elements, such as molybdenum, chromium and vanadium. These alloys improve wear resistance and toughness. It is able to withstand temperatures of that reach 600°C. This means that it loses its hardness from 650degC onwards. You can however run the high-speed steel tools under surface treatments to prolong the life span of the tool.

They can be used to drills, broaches and single-point lathes.

3. Cemented Carbide Tool

Cemented carbide tools are the result of the process of powder metallurgy. It composes tantalum, tungsten, and titanium carbide, and cobalt serves as the binder. The tool is referred to as cermet if nickel or molybdenum are used as the binder. These tools are considered extremely hard because they are able to keep their hardness to nearly 1000 degrees Celsius.

High cobalt cemented carbide tools are great to make rough cuts. The tools that has lower cobalt is utilized to finish. They are best suited for the machining of non-ferrous metals as well as cast iron.

4. Ceramics Tool

Normally aluminum oxide and silicon nitride act as efficient ceramics materials. Ceramics are chemically inert and aren't easily joined to metals. They are extremely durable in terms of heat, wear, and corrosion resistance, in addition to having high hardness. Additionally, ceramic tools operate 10 times faster than tools made of HSS. They maintain their stability up to 1800°C. So, no coolant is required.

Ceramic tools are vital in dry, high-speed and hard cutting. It can also be used to cut hard-to-machine materials manufacturing. Ceramics tools should be used in CNC machines to meet high-speed requirements.

5. Cubic Boron Nitride (CBN) Tool

Cubic Boron Nitride, which is the second-hardest of all cutting tools, is extremely sought-after. It's a great thermal conductor, with exceptional thermal stability. It can be heated to temperatures up to 10000°C.

Cubic Boron Nitride tools are perfect to process hardened steel workpieces. Additionally, it is able to cut through hard cast iron, cement carbide, superalloy, and more. However they pcd reamer manufacturer are not suitable for the materials with high plasticity.

6. Diamond Tool

Diamond is among the most rigid and expensive substances known to mankind. It is thermally conductive and has a high melting point. Diamond tools can help you get a perfect surface finish and dimensional precision. Besides its advantages but it also has a low thermal stability, because of which it loses hardness once temperatures go over 700degC-800degC. This makes it unsuitable to cut ferrous metals.
