Contact hardware cutters: features, characteristics, types, materials and application

Krympress reports:

The end cutters of the solid -melting are the most important tool in the arsenal of a modern metal processor. They are used in various industries for processing materials with high accuracy. This type of milling plant is durable. A more — high performance, which makes it indispensable in machining.

The main characteristics of the terminal milling plants

The end cutters of the solids have several important characteristics that determine their effectiveness and applicability in production processes:

• The diameter of the cutter — one of the key characteristics that affects the maximum size of the processed hole and processing accuracy.
• the number and shape of the teeth — They determine the quality of processing and the ability of the cutter to cope with various types of materials.
• The surface roughness — The quality of the cutter surface is directly related to its service life and the quality of the processed materials.
• front and rear angle — Their correct choice affects the effectiveness of cutting and the durability of the tool.
• cutting speed and feed — These parameters depend on the type of processed material and cutters.

The importance of choosing the right diameter

When choosing the diameter of the end cutter, it is necessary to take into account not only the size of the processed part, but also the thickness of the removed layer. The smaller the diameter of the cutter, the more accurately the processing can be done, especially when it comes to small holes or details with accurate tolerances. At the same time, for more rough processing of large blanks, it is optimal to use cutter of larger diameter, which allow you to increase the speed of the material and ensure the stability of the tool.

Types of terminal milling

Mills can vary in several criteria, including the design and type of teeth. The main species include:

Direct teeth mills

• Peculiarities: teeth are located along the cutter axis, which allows you to use them for deep processing.
• Application: processing materials with good surface strength.

Spiral teeth mills

• Peculiarities: The spiral shape of the teeth provides a more smooth removal of chips and improves cooling.
• Application: are used for high -speed processing, where high accuracy is required.

Cutters with inserts

• Peculiarities: These cutters have interchangeable cutting elements, which can significantly reduce the costs of the tool.
• Application: for serial production, where it is important to quickly change mills.

Diamond cutters

• Peculiarities: Coating with diamond significantly increases the term of the cutter’s service.
• Application: processing of particularly solid materials, such as graphite, carbon composites and others.

The role of teeth in the milling process

The number and shape of the teeth on the cutter directly affect the quality of processing and cutting speed. Treens with a large number of teeth are usually used for fine processing, where it is important to ensure high surface quality and accuracy. In turn, milling cutters with smaller teeth and coarser angles are ideal for processing solid materials, which requires high power to remove a large volume of material in a short time.

Materials for the manufacture of milling

Spended cutters are made from various types of materials, depending on the field of application and requirements for their characteristics.

1. Tungsten carbide (WC) — the main material for most solid milling mills. It has high hardness and resistance to wear.
2. Cobalt -containing alloys — Adding cobalt can improve the strength of the cutter at high temperatures.
3. Borid Titan — It is used for milling plants that will be exposed to high temperatures.
4. Diamond coatings — They are used in cutters for processing super -hard materials.

The use of end mills of solid

Shipping mills are widely used in various industries:

• Mechanical engineering — for processing metal parts.
• Aviation industry — for the manufacture of parts of design of aircraft and helicopters.
• microelectronics — for the production of complex electronic components.
• automotive industry — Processing of engines, transmission and other components.
• Metal processing — cutters are actively used for cutting and processing various types of metals.

How to choose a fraudimatical milling cutter

The correct choice of cutters depends on many factors. Here are a few key criteria that should be taken into account:

Type of material

• The choice of cutter depends on which material the tool will work with. For soft metals, cutters with a smaller number of teeth are suitable, and for hard — with a high number of teeth.

Geometry of teeth

• The teeth should be selected depending on the type of operation (smooth or rough processing).

The angle of inclination of the teeth

• The angle of inclination of the cutter depends on the type of cutting. For easy processing, the angle of inclination should be less, for more complex operations — more.

Size and shape of the cutter

• The diameter, length, and the shape of the cutter determine its application. For deep holes, cutters with a larger length and diameters are selected.

Coating material

• The presence of coating, such as TIN, Tialn or DLC, significantly increases the terminal service life of the cutter.

The effect of coating on the durability of the tool

The cutting of the cutter, for example, TIN (titanium nitride) or tialn (titanium nitride with the addition of aluminum) significantly improves its wear resistance. These coatings reduce friction, prevent overheating and protect the cutter from chemical exposure when processing aggressive materials. In some cases, the use of the coating can increase the service life of the tool several times, which is especially important in mass production.

Experts note: terminal cutters of solid -melodious are an indispensable tool for professionals in the field of mechanical engineering and processing of materials. The choice of the correct cutter plays a key role in the quality and speed of work. With the right choice of material, type of cutter and processing technology, you can significantly increase productivity and reduce the wear of the tool.

Note that with the development of technologies, tool manufacturers constantly introduce innovation, improving the characteristics of milling plants. For example, now cuts with multi -layer coatings are actively used, which allow you to process ultra -free materials without overheating and accelerate the cutting process. Modern cutters are also equipped with technologies that allow you to effectively remove chips, which minimizes the risk of overheating and damage to the tool.
