Turning carbide insert – These are used to deliver axially symmetrical shapes on a rotating workpiece with a stationary single point edge.

Now the inserts are heated up to 1500 degrees celcius up to 13 hours in a sintering furnace to make it hard. This eventually melts it into cemented carbide. After acquiring targeted hardness, they are grinded to gain accurate sizes and geometry.

The largest depth of cut is always ideal option for the selecting the right carbide turning insert. For determining tool holder entering tool and machine specifications etc consider the cutting length of carbide inserts.

Holders – It supports carbide turning inserts to make sure the insert is rigid and strong which minimizes the deflection and vibration during the operation.

Boring bars – they are cylindrical bars for internal machining to make holes in the machined material like solid carbide and steel etc.

Clearances are also relief angle value. The purpose of the clearances is to prevent wall of the carbide inserts to rub with the part that offers inferior machining. The ANSI B212, 122-1991 has given standard with nine relief angle denoted by capital letters.

The carbide turning inserts, also known as indexable inserts are tools that cut the material in a machining process. They give great surface finishes on metal materials.

Finishing – Feasible for light depth of cuts and has low feed rates. It is best for machining operations that require low cutting forces.

Drilling carbide inserts – These are used to drill large diameter holes. They run at much higher speeds are very economical.

Milling carbide inserts – These are used for machining some of the toughest materials to cut or shape them like steel, titanium etc.

The ISO code uses metric system where measurements are in millimeters. Each specification of a carbide insert is attached with a special coding system that relates with following phrases:

Though the large nose angle is sturdier but in fact it requires higher machine power and as a result also causes higher vibrations during machining. On the contrary, small nose angle is weak but gives small engagements with cutting edge resulting in lesser vibrations which is why the tool is sensitive to heat effects.

As explained earlier, they machine different metals with accuracy. You can either change them, flip or rotate them etc. The good news is they are not welded to the machine and are removable.

Consideration of manufacturer is important. It decides whether the product is high quality. An ideal manufacturer should have one of the best facilities and machinery. It should have skillful resources and best CNC production line.

Roughing – It is the combination of high feed rate and depth of cut and suitable for most operations requiring high edge security.

These elements define the coding process which makes easy to select the carbide insert. The coding system is a universal framework which provides ease to manufacturers to select the right carbide insert.

The carbide turning inserts are made into various shapes that functions for specific purpose. Due to this, the manufacturing is very careful to make sure the meet the accuracy and proper dimensions required. Here are some highlights on its manufacturing.

It defines the carbide insert’s cutting edge length. The measurement is defined by either one or two-digit number indicating inscribed circle’s value. Furthermore, it also defines number of eights in an inch.

Threading carbide inserts – These types of inserts are also called threaded bushing and are specifically inserted in an object to deliver threaded hole.

The mixed powder is then transported to manufacturers in containers hat weigh 80 kg approximately. The powder is filled in dies in a specific order and pressurized up to 12 tons. But they are still weak.

Drill – It is a shaft with cylindrical shape and conical cutting tip having one or more helical flutes to let chips escape the workpiece during machining.

Using a carbide turning insert on a project is daunting one as the tool is prone to damage or destroy the material itself. In that case, a manufacturer who gives sufficient after sales services should be opted. The after sales provided builds the trust over customer.

In this article, you will get to know exactly what are the factors that you need to consider for selecting the right carbide turning insert.

But when these cutting tools are manufactured in carbide material, their strengths are drastically increased, and they show unique properties which led to machinist utilize them. In this article you will know what is a carbide turning insert? How to identify one, what are different types of carbide turning insert and much more. So let’s get started.

Carbide turning insert should be selected according to specific purpose and application. For better stability, it is preferable to use large sized carbide turning inserts. For using carbide inserts on heavy machining process, use size above IC 25mm.

Seat – It is a piece similar to the size of carbide turning insert which is placed between bottom of packet and insert where the insert fits tool holder.

The turning inserts are such cutting tools that are used to machine different metals like steel, carbon, cast iron, and high-temperature alloys. They are indexable which means they can be rotated, flipped, exchanged with other insert without the need to disturb te tool geometry.

It is the level of accuracy of carbide inserts during machining. There are fourteen tolerances classes that are offered for the inserts.

A coding system is developed by American National Standards Institute that determines the selection of right carbide turning insert. It consists of letters and numbers that describes the shapes, dimensions and other parameters.

Grooving carbide inserts – The grooving carbide inserts are used for cutting grooves either internally or externally. But it can also be used for various machining operations.

Letter A, B and T defines dimensional tolerances where A is inscribed circle dimension, B is height of trigon, pentagon or triangle shape and T is the dimension of thickness.

While the carbide turning inserts do such a good job, selecting the wrong carbide turning insert can ruin your material, project and costs you a lot. Therefore, the manufacturers working with with machining operations need to completely understand what to look for in selecting the right carbide turning insert. They should be able to read the codes, and understand what shape and geometry they require to fit their need.

Now the inserts are passivated and coated. Then they are placed on turntable holders and transported to a coating furnace with lower coating pressure. The process of making inserts is completed once the coating procedure is done.

To acquire best results, it is necessary to use carbide turning inserts with other accessories that are equally important. They are used during all workpiece operations.

In fact, the tool grade and geometry go hand in hand. For instance, the toughness of a tool’s grade can be compensated with low strength in geometry.

The carbide turning inserts are used at high speeds that results in better and faster material surface finishes. This way, you can also reduce the damaging of carbide inserts, the material as well as the workplace. They are available in market with variety of grades, sizes, styles etc.

Since for different applications, carbide turning inserts with various sizes are used, users should prefer such manufacturer that produces many varieties of carbide inserts. This proofs the manufacturer is reliable to make a purchase and buy his product.

The researchers and developers gave an ideal system called Turning Tool ISO Code System to identify the carbide turning insert. The advantage of using this coding system is to select the specific carbide turning insert that fits precisely to your needs.

The selection of right carbide turning insert will save great time, cost, and will deliver quality finish. On the other hand, careless selection of the carbide insert will destroy your product and will costs much to your business. Though there are many parameters defined by ANSI coding system, the users of such tools should be aware of at least the basic parameters by ANSI in order to select the right carbide insert.

While selecting the carbide turning insert, make sure the tool has correct entering angle. It is preferred to choose the largest nose angle available that provides insert and reliability but it also needs to be balanced with cuts variation.

They are mainly made of carbide or tungsten in different proportions, and are originally in raw powder and wet form. Then in the workshop, the raw materials are mixed with water and ethanol to produce a mixed solvent.
