Carbide plates. Turning inserts Carbide inserts for milling cutters dimensions

Carbide plates are classified according to GOST 19042-80. Cutting products are used in the manufacture of the working surface of the tool. Carbide support plates are used to fix the blades. They ensure precise positioning of the cutting part. The purpose of chip breaking plates is to crush metalworking waste. All carbide products have design and dimensional features. The plates additionally differ in the number and shape of edges, the presence of holes, and the size of the rear angle:

  • Single-sided (R, M) and double-sided (N, A, F, G);
  • With a flat edge (N, A) and with chip breaking grooves (R, M, F, G);
  • With hole (A, M, G) and without hole (N, R, F);
  • With zero clearance angle (N) and with clearance angle greater than 0.

Double-sided carbide inserts are more durable, but have less rigidity, strength and stability than single-sided carbide inserts. Products with a clearance angle N are installed in the holder in such a way as to achieve the desired parameters. When choosing, you should pay attention to the configuration of the front edge. The presence of a chipbreaker is an important factor for operation. Proper use of replaceable multifaceted inserts for their intended purpose helps to increase the service life of metal-cutting tools.

Production of carbide inserts

Modern hard alloys with an improved formula are used to manufacture multifaceted attachments. Geometric accuracy of execution is a mandatory characteristic that ensures a significant reduction in the percentage of defective products in metalworking. Specific parameters of carbide inserts are regulated by standards. GOST 19086 defines the technical characteristics of chip breakers, cutting and support attachments. When producing brazed products, enterprises are guided by GOST 25395.

Advantages of replaceable carbide inserts

Important point. Replaceable multifaceted inserts made of hard alloys are not intended for use with solid tools made in the form of monolithic products from a holder and a working part.

Our catalog contains replaceable multifaceted plates made of cermets, CBN and other hard alloys. All products retain their original properties when heated to 1150 °C. Certain materials are used to process different surfaces. A large range of carbide products allows you to perform all types of work by changing multifaceted inserts. This solves the problem of reusing the holder, reducing the cost of cutting tools and consumables while improving the quality of processing.

The appearance on the market of replaceable multifaceted inserts for turning tools and milling cutters has led to the elimination of regrinding. As a result, it became possible to reduce the number of sharpeners in production, reduce costs for special equipment and abrasives, and save useful space. There is no need to solder the cutting part, so the cost of tool manufacturing and solder has decreased. Quick replacement significantly increases productivity and saves working time. The advantages of using carbide inserts are obvious:

  • The versatility of one cutter to perform different operations;
  • Economic benefit from replacing inserts rather than tools;
  • Wide selection of carbide nozzles for various purposes;
  • Increased speed and productivity in metalworking;
  • Increased convenience due to the ability to change modes.

The use of replaceable multifaceted plates is especially beneficial in small enterprises and in everyday life, where saving not only budget, but also space is important. A set of carbide bits costs significantly less and takes up less space than a corresponding set of cutters or cutters, while performing similar functions. Multi-faceted inserts are successfully used for surface processing, cutting sheet materials, thread formation, boring and reaming work, making grooves and drawing grooves.

Replaceable carbide inserts - what are they used for?

Increasing the productivity and efficiency of work on metalworking equipment is the desired goal for every entrepreneur. This can be done using turning carbide inserts, which are presented on the market in various modifications. They are designed for high-precision processing of parts on machine tools. It is very advisable to use these tools, because their main advantage is that they can be quickly replaced when they wear out or lose performance. This allows you not to disrupt the production process and complete the required amount of work on time.

The main materials for manufacturing are pressed powders of tungsten carbide and titanium carbide with cobalt. The manufacturing process is quite complex from a technological point of view. It includes many preparatory steps and manipulations:

  • at the first stage, powders are mixed in different proportions, which directly affects the physical properties of the finished parts;
  • Then the powder mixture can be pressed. It is poured into special molds and then subjected to high pressure;
  • the resulting blanks are sintered and transformed into cutters;
  • at the final stage, the finished products are coated with a physical or chemical protective layer. It is worth noting that this stage is not always followed, but only when necessary.

In addition to your order, you can buy ones that are distinguished by high quality workmanship and durability.

Advantages of turning carbide inserts

Such cutters are widely used today in medium- and small-scale production, where the number of types of products is large and the nomenclature changes regularly. This is due to their undeniable advantages:

  • efficiency. In the event of a breakdown, you don’t have to replace the whole cutter, but get by with replacing the cutting part if it is replaceable and not solid. This process is simple and requires only basic knowledge when working with turning equipment;
  • manifold. Turning parts can be made from different alloys, which allows you to have a whole set of cutting elements in production;
  • reliability. They have a long service life even with intensive use;
  • unification. All modern modifications are unified, which makes it easier to choose the most suitable option for a specific workpiece, as well as its type of processing.

Classification of cutter inserts:

  • type of tool. Turning cutters are divided into scoring, cutting, shaped and others. The type influences the selection of a specific profile shape, which is formed at the production stage;
  • material. Product quality may vary. They depend on the amount and ratio of metals in the composition. Titanium and tungsten have a particular influence. In addition to metal plates, there are also ceramic ones. They have a narrow scope of application, which is limited to the processing of products made of alloys resistant to high temperatures and finishing of workpieces;
  • method of fastening. Fastening to the mandrel or holder is carried out mechanically or by soldering, which does not allow the cutters to be replaced. In this regard, it is worth giving preference to the first option. It has many positive aspects, among which it is worth highlighting the possibility of reusing the holder;
  • size. The size of turning carbide and their geometric parameters are selected depending on the workpiece to be processed;
  • rear angle value. You can find this parameter on the label. It implies purity of processing. If the angle is large, then the level of cleanliness will be high and the roughness will be lower, and vice versa;
  • accuracy. Manufacturers of turning tools produce inserts in five accuracy classes.

In order for the parts to meet all expectations in the future, they should be selected very carefully. Particular attention must be paid to the coincidence of the dimensions with the dimensions of the cutter. They must fit each other perfectly. If this is not the case, then it will be impossible to secure the part.

Turning inserts, presented on the market in a huge variety of modifications, are mandatory equipment for metalworking equipment. The accuracy of the work performed, and therefore the efficiency and overall productivity of the enterprise, will depend on its quality.

Purpose of turning inserts

The main purpose of turning plates is high-precision processing of metal workpieces on special machines, in small-scale and medium-scale production with a regularly updated range. Thanks to the possibility of quick replacement, they allow you to ensure uninterrupted work processes with the production of the required volume within a precisely specified time frame.

Classification of carbide inserts

Carbide inserts for turning tools are represented by a variety of types, which are classified according to the following criteria:

  • manufacturing materials: metal and ceramic. The highest quality is considered to be a metal plate with a high content of tungsten and titanium. Ceramic ones are characterized by resistance to high temperatures and high cut quality, therefore they are used for finishing the material;
  • type of plates: shaped, scoring, cutting, etc. Replacement equipment is selected depending on the required profile shape;
  • method of fixing the tool: brazed and mechanical. The latter version of the discs is more profitable, since it allows you to change the cutters as they wear out;
  • the size of the angle of the equipment. The higher this indicator, the higher the quality of workpiece processing will be;
  • accuracy, which is represented by 5 classes;
  • size. Selected depending on the geometric parameters of the workpiece.
