Turning inserts: the best choice in the cutting world

Turning inserts are tool components used in lathe machining. Their main function is to remove excess material from the workpiece through the relative movement between the rotating workpiece and the fixed insert, thereby machining the workpiece into the desired shape and size. It is like a precise carving tool that can cut a variety of materials and plays a key role in the field of mechanical manufacturing.

Compared with traditional tools, carbide turning inserts have the following advantages

1. High hardness and wear resistance:

The hardness of carbide is much higher than that of traditional tool materials, such as high-speed steel. This allows carbide turning inserts to maintain good edge sharpness during the cutting process and resist the wear of the workpiece material on the blade, thereby greatly extending the service life of the blade. For example, when processing materials with higher hardness such as alloy steel and hardened steel, the wear resistance of carbide inserts is particularly obvious, which can maintain stable cutting performance for a long time, reduce the frequency of blade replacement, and improve processing efficiency.

2. High strength and toughness:

Carbide materials are not only hard, but also have certain strength and toughness. In turning processing, they can withstand greater cutting forces and impact forces, and are not prone to chipping and fracture. In contrast, traditional tool steel tools are prone to deformation and damage when subjected to greater loads, affecting processing accuracy and production efficiency.

3. Good thermal stability:

A large amount of heat will be generated during the turning process, causing the tool temperature to rise. Cemented carbide has high heat resistance and thermal stability, can still maintain good mechanical properties at high temperatures, and is not easy to soften or deform due to high temperatures. This makes cemented carbide turning inserts have good adaptability under high-speed cutting, dry cutting and other working conditions, and can ensure processing quality and precision.

4. High precision and good cutting performance:

The manufacturing precision of cemented carbide turning inserts is high, and the dimensional accuracy, shape accuracy and edge quality of the blades can be well guaranteed. This enables the blades to achieve precise cutting during the cutting process, and the workpieces processed have high dimensional accuracy and good surface quality. At the same time, the cutting edge of cemented carbide inserts is sharp and the cutting resistance is small, which can reduce cutting force and cutting power, reduce the load of machine tools, and improve processing efficiency.

5. Wide range of applications:

Cemented carbide turning inserts can choose different blade materials, shapes, sizes and coatings according to different processing requirements, and are suitable for turning processing of various materials, including steel, cast iron, non-ferrous metals, high-temperature alloys, etc., whether it is rough processing or fine processing.

Application scenarios

1.Roughing: 

In the roughing stage, turning inserts are mainly used to quickly remove large amounts of material. At this time, inserts with larger cutting edges and stronger toughness are usually selected, such as large-sized square carbide inserts. These inserts can withstand larger cutting forces and use larger cutting depths and feeds to improve processing efficiency. For example, when machining the blanks of large shaft parts, roughing turning inserts can quickly remove excess material and make the workpiece close to the final size profile.

2.Semi-finishing:

 The semi-finishing stage is to further improve the dimensional accuracy and surface quality of the workpiece on the basis of roughing. At this time, the turning inserts selected must have good cutting stability and edge accuracy, such as diamond-shaped carbide inserts. By appropriately reducing the cutting depth and feed rate, the workpiece is processed using the high-precision edge of the insert to prepare for finishing.

3.Finishing: 

Finishing requires turning inserts to be able to process high-precision, low-roughness workpiece surfaces. Generally, blades with sharp edges and high precision are selected, such as ceramic inserts or carbide inserts with fine coatings. At this stage, the cutting depth and feed rate are very small, and the blade is mainly used to perform fine cutting on the workpiece surface. For example, when processing high-precision parts such as sleeves, the finishing turning blade can make the workpiece surface roughness reach Ra0.8μm or less.

Models

1.Classification by material: mainly carbide turning blades, ceramic turning blades, metal ceramic turning blades, etc. Carbide turning blades have high hardness and toughness, suitable for processing most materials; ceramic turning blades have higher hardness and wear resistance, suitable for high-speed cutting and processing hard materials; metal ceramic turning blades combine the advantages of carbide and ceramics, with good cutting performance and wear resistance.

2.Classification by shape: common ones are triangle, square, diamond, circle, etc. Turning blades of different shapes are suitable for different processing occasions, for example, triangular blades are suitable for rough processing, square blades are suitable for semi-finishing and finishing, and diamond blades perform well in thread processing.

3.Classification by use: including external turning blades, internal hole turning blades, cutting turning blades, thread turning blades, etc. Each type of turning blade has its specific design and use to meet different processing needs.
