How to distinguish the turning tool and the milling cutter of the CNC insert from the model

There is a unified representation method for ordinary machine clamping and turning inserts in the world, but the representation methods of slot inserts and milling inserts are different from manufacturer to manufacturer.

According to the international standard of ISO, in fact, the commonly used milling inserts and turning inserts are the same in terms of nomenclature, but with the complexity of processing. Standard inserts are difficult to meet some machining needs, which leads to the emergence of inserts with different nomenclatures. This is mainly related to the manufacturer.

Generally speaking, the difference between a milling insert and a turning insert is the relief angle of the insert. The turning blade is generally a processing cylinder, and its surface will have a circular arc, so the clearance angle required by the turning blade is generally not too large. It is generally 0 degrees.

Or 5 degrees 7 degrees. The milling insert is often processed flat and has no arc, so the rear angle of the milling insert is required to be larger. In order to prevent interference with the workpiece and affect the machining quality, most of the milling inserts have an angle of 11 degrees.

20 degrees, etc. Take apkt160408** as an example; A stands for shape. p stands for rear angle. k stands for tolerance.

t represents the shape of the screw hole; 16 blade blade length, 04 for thickness. 08 represents the R angle; The latter ** is related to the manufacturer. Among them, there are edge treatments, chipbreaker forms; *This often represents the material of the blade.

It is also related to the manufacturer.

Look at the turning blade CNMG120408** You follow the above comparison, so the nomenclature is basically the same, mainly from the perspective of the blade to distinguish and processing occasions.

Each brand is different, and the way to distinguish it is also different.

But you can tell what each letter represents, based on the presentation in the sample.

Perception of blade model: For example, TNMG160408-MA-US735, this is the model of Mitsubishi blade, look at the initials, T represents its shape, indicating that it is triangular. n represents its trailing angle, which means that the trailing angle is 0°.

m is the accuracy code; G is the groove and hole code, which means that there is a gap in the middle of the cutter grain, and the double-sided chip breaker groove; Doosan 16 represents the cutting edge length and inscribed circle, 04 represents the thickness of the insert, and 08 represents the arc of the cutting edge. MA stands for geometry. US735 is the material code, which is specially used to drive stainless steel.

Data Development:

1. CNC blade is the general term of indexable turning blade, which is the mainstream product in the field of modern metal cutting applications. It is mainly used in metal turning limb cutting, milling, cutting and grooving, thread turning and other fields. According to the material, it can be divided into coated blades, cermet blades, non-metallic ceramic blades, carbide blades, superhard blades, etc.

It is characterized by high efficiency and high wear resistance, and the processing efficiency is more than 4 times higher than that of traditional welding blades and alloy blades. With the continuous progress of coating technology, breakthroughs in key technologies of wear resistance and high temperature resistance will further improve efficiency and reduce processing costs.

Second, there are many kinds of CNC blades, widely used, and now the market to buy CNC blades business is mainly the following kinds of blades:

1. Monolithic: It is made of grinding from a whole piece of material, and the cutting part can be ground into the required shape according to different purposes.

2. Mosaic type: It is divided into welding type and machine clamp type. The clamp type is different according to the structure of the cutter body. It can be divided into two types: non-indexing and indexing.

3. Shock absorption: when the ratio of the working arm length to the diameter of the tool is greater than 4, in order to reduce the vibration of the tool and improve the machining accuracy, a special structure of the tool is adopted. It is mainly used for boring.

4. The cutting coolant of the internal coolant tool is transmitted to the inside of the cutter body through the spindle or cutter head of the machine tool, and is sprayed to the cutting edge by the nozzle.

5. Special types: including strong clamping, reversible tapping, composite tools, etc. At present, CNC tools mainly use machine clamp indexable tools.

Generally, the blade model is represented by 10 numbers. The first four letters of this model number indicate the characteristics of the blade, followed by six numbers indicating the size and model characteristics of the blade.

DNMG150408-MS is an insert, D represents a 55° diamond blade, N indicates that the rear angle of the insert is 0°, M is the accuracy level of the insert manufacturing, G represents the rake edge face and center hole type, 15 indicates the cutting edge length value is 15mm, 04 indicates the thickness of the insert, and 08 indicates the radius of the arc of the cutting edge.

The specific identification method of CNC blades.

1) The first letter generally indicates the shape of the CNC blade, and the commonly used ones are usually H, O, P, S, T, C, D and E, which are hexagonal, octagonal, pentagonal, square, diamond 80 degree top angle, diamond 55 degree top angle and diamond 75 degree top angle.

2) The second letter is obviously to indicate the angle of the rear angle of the blade, the commonly used letters are usually A, B, C, D, E, F, G, O, A means the angle of the rear angle is 3°, B is 5°, C is 7°, D is 15°, E is 20°, F is 25°, G is 30°, N is 0°, P is 11°, O means other rear angle angles.

3) The third letter indicates the accuracy level of the insert, the most commonly used are M grade and G grade, generally rough and semi-finishing finishing inserts are M grade, precision machining blades and superhard inserts are generally G grade.

4) The fourth letter indicates the rake face and center hole type (groove and hole) of the insert.

5) There are a total of 6 numbers, divided into three groups, the first group indicates the blade edge length, the second group indicates the blade thickness, and the third group indicates the radius of the blade tip arc.

6) The letters behind indicate the material of the blade, there are many materials of CNC blades, and the products produced by different materials will naturally be different, so when buying CNC blades, we must pay attention to the choice of blade materials, and different materials are also completely different.

Generally used two letters to denote, most of them are alloys, P represents a mountain of jujube-like steel, M represents stainless steel, K represents gray cast iron or ductile iron, N represents aluminum scrap metal , S represents heat-resistant alloy or titanium alloy, H represents high hardness material, etc.

The meaning of the milling cutter model and letters:

The preceding letters generally indicate the code of each manufacturer. The middle digit generally indicates the specification and model. Some are international standards. Some are the manufacturer's standards.

The following letters represent materials suitable for processing. Comply with ISO international standards. P stands for General Rigid. M stands for stainless steel. K stands for cast iron. n stands for non-ferrous metals. S stands for heat-resistant alloy. h stands for high hardness material.

The main purpose of the milling cutter:

1. Flat-head milling cutter, rough milling, removal of a large number of blanks, small area horizontal plane or contour precision milling.

2. Ball nose milling cutter, for semi-finish milling and finish milling of curved surfaces; Small ball nose cutters can be used to fine mill steep faces, small chamfers of straight walls, and irregular contour faces.
