Introduction to the classification and characteristics of CNC machining tools
March 06, 2022
CNC machining tools must adapt to the high speed, high efficiency and high degree of automation of CNC machine tools. Generally, they should include general-purpose tools, universal connecting shanks and a small number of special shanks. The shank is to be connected to the tool and mounted on the power head of the machine, so it has been standardized and serialized.
Classification of CNC tools:
a. According to the tool structure, it can be divided into (1) integral type;
(2) Inlaid type, using welding or machine clamp type connection SOOQ.cn copyright, machine clip type can be divided into two kinds of non-indexing and indexable;
(3) Special types, such as composite tools, shock-absorbing tools, etc.
b. According to the materials used to manufacture the tool can be divided into:
(1) high speed steel cutters;
(2) Carbide tools;
(3) diamond cutters;
(4) Other material tools, such as cubic boron nitride tools, ceramic tools, etc.
c. From the cutting process can be divided into:
(1) Turning tools, which are divided into outer circle, inner hole, thread, cutting tool, etc.;
(2) Drilling tools, including drill bits, reamers, taps, etc.;
(3) boring tools;
(4) Milling tools, etc.
In order to meet the requirements of CNC machine tools for durable, stable, easy to adjust, changeable, etc., in recent years, the machine-clampable indexable tool has been widely used. , the number of the entire CNC tool is 30%. 40%, the metal removal amount accounts for 80% to 90% of the total.
2. Compared with the tools used on ordinary machine tools, CNC tools have many different requirements, mainly including the following features:
(1) Good rigidity (especially rough machining tools), high precision, anti-vibration and small thermal deformation; good interchangeability, easy to change the knife quickly;
(2) High life, stable and reliable cutting performance;
(3) The size of the tool is easy to adjust the metal processing network to reduce the tool change time;
(4) The tool should be able to reliably break the chip or the chip to facilitate the removal of the chip;
(5) Serialization standardization for programming and tool management.
