CNC machining tools can be divided into two major categories: conventional tools and modular tools. Modular tools are development directions. Main advantages of developing modular tools: reducing switching time, increase production and processing time; speeding up knife and installation time, improving the economics of small batch production; improving the standardization and rationalization of tools; improving tool management and flexible processing Level; expand the utilization of the tool, give full play to the performance of the tool; effectively eliminate the interruption of tool measurement work, and can be pre-adjusted. In fact, due to the development of the module tool, the CNC tool has formed three major systems, namely the turning tool system, drilling tool system, and boring tool systems.

Classification of CNC tools

(1) can be divided into structure

1 overall type

2 mosaic can be divided into welded and machine clips. The clip is different depending on the structure of the slogan body;

3 Damping type When the tool of the tool is relatively large, in order to reduce the vibration of the tool, improve processing accuracy, and use such a tool.

4 The internal cooling cutting liquid is sprayed from the cutting hole of the tool by the inner body body;

5 Special types such as composite tools, reversible threaded tools, etc.

(2) can be divided into materials from the materials used in the manufacture

1 High-speed steel cutter high-speed steel is typically a fabric, toughness, good hardware, hardness, abrasion resistance, and river difference, is not suitable for materials with high cutting hardness, and is not suitable for high-speed cutting. The producer can be blamed before the high-speed steel tool is used, and it is convenient to cover, suitable for non-standard tools for a variety of special needs.

2 The cutting performance of carbide cutting inductial alloy tool is excellent in cutting performance and is widely used in CNC turning. The carbide blade has standard specifications series products, specific technical parameters and cutting performance are provided by tool manufacturers.

The hard alloy blade is divided into three categories according to international standards: P Class, M, K.

P Class - suitable for processing steel, chip forged cast iron (equivalent to the YT class in my country)

M-class - suitable for processing austenite stainless steel, cast iron, high manganese steel, alloy cast iron, etc. (equivalent to YW class in my country)

M-S class - suitable for processing heat-resistant alloys and titanium alloys

K class - suitable for processing cast iron, cold coast iron, chip can forged cast iron, non-titanium alloy (equivalent to my country's YG class)

K-N class - suitable for processing aluminum, non-ferrous alloy

K-H - class - suitable for processing hardening materials

3 ceramic tool

4 cubic boron nitride tool

5 diamond cutter

(3) can be divided into from cutting process

1 Turning tool is divided into outer circles, inner holes, external threads, internal threads, slots, cutting ends, cutting surface, cutting, etc.

CNC lathes generally use standard clip-entered tools. The blade and the knife body of the clip can be converted to the blade have a standard, and the blade material uses a carbide, coated carbide, and high-speed steel.

CNC lathe clamp can be converted to the tool type has an outer cutter, an outer thread tool, an inner circular knife, an inner threaded tool, cutting tool, apertured tool (including a central well drill, a boring, tap, etc.).

Mane clamp can be used to clamp the blade, a screw, screw pressure plate, a bar or wedge, etc.

Square blade is typically fixed with grooved tool screws. The cylindrical rod is fixed to the sleeve screw. They are coupled to the connections between the machine tools and the sleeve and sleeve. In the modular turning tool system, the joint of the cutter is coupled to the rack handle, and the joint of the cutter head and the tool body is "inserted into the quick switch". It can be used for both outer cars and can be used for inner boring and automatic tooling systems for turning centers.

The tool used by CNC lathes is divided into three categories from cutting methods: round cutting tools, end face cutting tools and central apertures.

2 Drilling tool is small hole, short holes, deep holes, attack threads, hinges, etc.

Drilling tools can be used in CNC lathes, turning centers, and can be used in CNC boring and milling machines and machining centers. Therefore, it has a variety of structures and coupling forms. There are directly shank, straight shank screws, tapered shank, threaded coupling, modular coupling (tapered or cylindrical coupling).

3 boring tool is divided into a cutter and fine boring.

The boring knife can be divided into a monolithic boring handle, a modular boring handle and a boring head class. From the requirements of the machining process, it can be divided into a crude boring knife and fine rod.

4 milling cutting tool with face milling, vertical milling, three-sided edging and other tools.

The surface milling knife (also called the end mill) The circumferential surface of the plane milling cutter has a cutting edge, and the end cutting edge is a sub-cutting edge. Face milling tools are made into a sleeve arrangement and a blade machine clamp, and the tool tooth material is a high-speed steel or a hard alloy, and the tool body is 40 cr.

The vertical mill end mill is a milling cutter for the most controlled machine. The cylindrical surface and end faces of the end mill are cut, which can be cut simultaneously, or separately. Structure has an integral and halphism, etc., high-speed steel and carbide are common materials for milling cutters.

The mold milling cutter mold milling cutter is developed by a constant milling cutter, which can be divided into a conical mulk cutter, a cylindrical ball head milling cutter and

Three of the conical ball head milling cutter, and the handle has a straight handle, a flattening straight handle and a Mocetil handle. Its structural feature is that the ball head or end face is covered with a cutting edge, and the circumferential blade is connected to the ball head blade, which can be subjected to a radial and axial feed. The milling cutter work part is made of high-speed steel or cemented carbide.

Keyway milling cutter

Drum milling cutter

Forming milling cutter

(4) Special tool

Special knife has a handle, a strong spring tip tool handle, an inverse (automatic reverse) attack, screw chuck, a speed collet, a composite tool, and a pole class.

Characteristics of CNC machining tools

In order to achieve efficient, multi-can, fast change, economic purposes, CNC machining tools compared to ordinary metal cutting tools

Some features:

The height of the blade and the height of the blade and the height of the handle.

The rationality of the durability and economic life indicators of the blade or tool.

Standardization of tool or blade geometric parameters and cutting parameters typically.

Blades or tool materials and cutting parameters should match between the processed materials.

The tool should have a high precision, including the shape of the tool, the blade and the opposite position of the main shaft of the machine.

Advance, blade and shank transposition and removal accuracy of disassembly.

The strength of the handle is high, the rigidity and wear resistance are good.

The load capacity of the handle or tool system is limited.

The position and direction of the blade and the cutting handle are required.


The positioning base of the blade, the handle is optimized.


The tools used in CNC machine tools should meet the installation and adjustment, good rigidity, high precision, and good durability.
