Type I

Types of turning tools with replaceable inserts

The following types of cutting tools with replaceable inserts are distinguished:

Boring cutters: have a cone-shaped holder and mechanical fastening for making through and blind holes in parts. They can also be used for cutting internal and external threads in cylindrical products. When making blind holes, the cutting edge should be positioned at an angle of 90°, for through holes - at an angle of 60°.
Pass-through: used during external processing of metal parts. Their cutting edge is located at an angle of 45°.
Shaped: necessary for processing shaped surfaces. These cutting tools are capable of ensuring the identical shape and dimensional accuracy of the processed workpieces. Shaped cutters are made from high-quality high-speed steels.
Parting cutters: used for cutting workpieces into several parts. They are used when processing small and large bar parts. The main cutting edge of the tool is at an angle of 90°.
Multi-faceted carbide cutters: equipped with polyhedron-shaped inserts.
Grooving: intended for cutting grooves in cylindrical and conical products. They are characterized by high structural rigidity and high productivity. These tools are able to withstand high loads during turning operations.

The choice of the type of thread cutters with replaceable inserts depends on the type of technical operations performed during the processing of metal parts. The quality of the instrument depends on the precision of manufacturing and the professional skills of the craftsman.

Nuances of choosing a cutter

When purchasing cutting tools, you need to pay attention to the following criteria:

A type of cutting tool. Different types of cutters differ in profile shape, determined by the technical features of carbide inserts.
Dimensional characteristics. The different dimensions of products processed on a lathe determine the dimensions of the cutting tool. For modern types of cutters, you can select workpieces with distinctive dimensional characteristics.
Back angle value. This indicator affects the accuracy of finishing of the material. The surface cutting cleanliness is directly proportional to the clearance angle. This parameter is taken into account when turning metal workpieces with soft surfaces.
Accuracy class. This parameter is used to calculate the accuracy of the cutting performed. According to GOST 9253-59, 3 main accuracy classes are established for plates. When measuring this parameter, it is possible to cut workpieces with tools with different tolerance values.

If these criteria are not taken into account, then the thread cutters will not be able to be firmly fixed on the lathe and produce precise processing of metal parts.

When purchasing cutting tools, it is important to choose the right inserts. These parts are made of hard metal alloys. The ratio of metals determines the operating characteristics of the cutting tool. There are 2 main types of plates:

With increased strength. They are resistant to vibration, shock and other physical stress that occurs during cutting. It is recommended to purchase this category of plates if you need to cut a large amount of metal from the workpiece.
With increased heat resistance. They can withstand high temperatures that arise during long-term processing of workpieces and exposure to frictional forces. Heat-resistant plates are fixed mechanically. They are used when working at high speeds.

Materials of manufacture are indicated on the markings of carbide inserts. Each alloy has a unique image. In the manufacture of cutting parts, tungsten is used, which has high strength and resistance to large temperature changes. Additionally, titanium carbide or cobalt can be used. Plates made of ceramic materials are used during finishing or semi-finishing of metal products. They can be used for cutting workpieces made of heat-resistant alloys. The percentage of these components determines the category of replacement plates. On the marking, titanium is designated by the letter “T”, cobalt by the symbol “K”. Example of marking: T14K7 (percentage of titanium carbide - 14%, cobalt - 7%).

For large volumes of turning work, it is recommended to purchase a set of turning tools with replaceable inserts, which will allow you to quickly adjust the tool during various technological operations. When choosing sets, it is important to consider the manufacturer's brand. The most popular replacement plates on the market are from the following companies:

LLC “Instrument-Service”: a Ukrainian company that produces parts for cutting tools.
Interpipe: is the largest organization for the production of pipe and threaded connections in Eastern Europe. The products are manufactured at the Novomoskovsk pipe plant, located in the Ukrainian city of Dnepr.
BDS-Machinen: German company producing devices and parts for magnetic drilling machines.
Proxxon: an organization that develops parts for cutting small workpieces. Production takes place in Germany.
Ceratizit: a company producing metal-cutting tools and their main components. The headquarters is located in Luxembourg.

The cost of a set of turning tools depends on the manufacturer's costs and the financial policies of suppliers. Imported parts have the highest price. The average price of a set is 15,000 rubles. Additionally, you can purchase certain types of plates. Their average price is 164 rubles.

Cutting modes

Cutting modes are a set of parameters that determine the conditions for processing parts using a turning tool. The cutting process is influenced by the following factors:

Cutting speed is the path of movement of the machined surface of the workpiece relative to the cutting edge per unit time. Measured in m/min or m/s. In the drawings it is designated by the Latin letter V.
Feed is the path traveled by the cutting edge in 1 stroke or revolution of the workpiece being processed. Measured in mm/rev. In the drawings it is marked with the Latin symbol S.
Depth of cut is the distance between the machined and machined surfaces. It shows the amount of metal layer being removed. In the diagrams it is denoted by the Latin letter t.
The cross-sectional area of the cut layer is the product of the cutting depth and the feed. It is a nominal value and affects the presence of roughness. In the diagrams it is indicated by the Latin symbol f.

These parameters are tabular values and are specified in GOST 25762-83.

Download GOST 25762-83

Each type of cutting tools with mechanically fastened inserts has additional cutting modes. Cutting cutters carry out transverse movements, boring tools move longitudinally relative to the surface of the workpiece. During operation, the average speed of the cutting edges is tenths of mm. The feed is 0.1 mm/rev.

Advantages and disadvantages of incisors

Thread cutters with replaceable inserts have the following advantages:

low cost: cost less than solid type incisors;
allow you to save a large amount of time resources during the preparation of cutting tools for various technological operations;
the plates are able to withstand high loads because they are made of carbide materials;
cutting cutters can be used to process parts with small dimensions and uneven terrain;
the cutting tool can be readjusted if necessary;
high service life of the holders, which allows the tool to be firmly secured to the lathe;
do not require additional sharpening or soldering;
during processing, reduce cutting force and temperature by 35 - 40%;
provide the ability to change cutting modes on the fly;
unification of all cutter models: allows you to select the right insert for processing workpieces made of certain types of metals.

Experts highlight the following disadvantages of cutters with replaceable inserts:

due to the presence of many fasteners for carbide inserts, the total weight of the cutting tool increases;
cutters are not able to provide optimal geometric parameters of the cutting edge due to the different shapes of the plates and the peculiarities of their fastening;
high complexity of manufacturing cutting tools.

The quality of a thread cutter depends on the type of processing and cutting mode. The cutter retains its benefits longer at low cutting speeds and during internal cross turning. The cutting tool wears out faster during external longitudinal turning. To increase its durability, lubricating and cooling media are used. You can also increase the rigidity of the tool by increasing the area of the holder.

Modern turning tools

Home Articles Modern turning tools with replaceable inserts

Today, turning tools with replaceable inserts are very popular. The holder of such cutters does not come into contact with the material and does not wear out, which allows you to use the tool longer. Unlike those tools that are produced in a one-piece version, here you can change the plate on which the cutting edge is located to start performing a different type of work. This significantly speeds up the work process. If a part is worn out or broken, it can be easily replaced without interrupting the production process for a long time. Buying replacement inserts for cutters is much cheaper than purchasing the entire tool. Thanks to these properties, turning holders with replaceable inserts have become indispensable in production.

A cutting cutter with replaceable inserts has the following number of advantages:

● quick change of working cutting part;

● good compatibility with tools and units;

● high reliability even during intensive work;

● re-adjustment of cutting tools;

● relatively low cost of replacement parts.

The only disadvantages that can be noted are that these products can break if the plate is fastened incorrectly, and the products themselves are less durable, although in economic terms they are much more profitable.

There are cutters with inserts made of carbide and high-speed steel. These types of materials appear in almost all types of instruments. Which one to take depends on what materials you will be working with. High speed steel is good for soft metals. It is relatively cheap, but performs very poorly when working with refractory and hardened workpieces. Lathe cutters with carbide inserts are more expensive, but they work with all types of metal and can withstand both temperature increases during active work and shocks.

Otherwise, the choice depends on the type of work for which the tool is taken. The features of its sharpening and other factors that turn out to be very important for the technologically correct execution of actions depend on this.

Cutters with plates made of carbide, as well as those made of high-speed steel, have several varieties, which depend on what kind of work they will be intended for.

Here are the following varieties:

■ Mechanical thread cutter - this tool can be used to cut internal and external threads on cylindrical workpieces.

■ Boring cutters with mechanical fastening - they are used to bore through and blind holes in workpieces. Depending on what kind of hole you have to work with, there are persistent ones, which grind blind holes, including processing the bottom, as well as through ones, for through processing. You can also use pass-through machines to process cylindrical surfaces.

■ Shaped - this is one of the most complex types that goes beyond accepted standards, as it has an individual profile. Some of them are made to order, so they have a lot of processing options.

■ Cut-off cutter with mechanical fastening – used for cutting off excess parts, both large and small, from workpieces. Mainly used for rod blanks.

■ Slotted – used for cutting circular grooves over the entire surface of the workpiece.

■ Fillet – used for turning the transition surface, which is located along the entire radius between the shaft steps.

Currently, carbide tools are the most progressive and widely used for industrial purposes. This material has high hardness and heat resistance. For metal working tools, carbide alloys are manufactured in the form of plates with various shapes and sizes. Installation of such plates is quite simple, and their increased level of wear resistance guarantees stable operation and saves money.

Carbide, high-speed and alloy steel materials are characterized by increased hardness and heat resistance compared to tool steel, so processing of workpieces is possible at high rotation speeds. Metal turning tools made from this material are more fragile. To determine the grade of carbide cutting element, they usually use special cards that describe the types of all areas of application under various processing methods and conditions.

Carbide alloys allow you to work at high cutting speeds of the workpiece; they are divided into the following categories:

◆ Metal-ceramic:

— Tungsten alloys are made from tungsten and cobalt carbides. Used for processing viscous materials, milling solid surfaces, boring cast iron under loads.

- Titanium tungsten. The material consists of tungsten and titanium carbides with the addition of cobalt. Suitable for rough and fine boring and cutting of steel.

— Titanium tantalum tungsten. In addition to titanium and tungsten, the alloy contains tantalum. Due to its high toughness, wear resistance and impact resistance, it is indispensable for working with steel forgings.

◆ Mineral-ceramic – a synthetically derived alumina-based alloy. It has high heat resistance, but has a fragile structure. Microlite plates can heat up to 1200 degrees without losing their hardness.
