Tool selection and cutting dosages
Nc machining tool must adapt CNC machine speed, efficiency and high degree of automation, generally should include general common connection, and a special handle grip. To connect the power tools and machine head, therefore in the standardization and serialization already gradually. The classification of nc tool has a variety of methods. According to the structure of tools can be divided into: (1) the single-piece, 2 inlaying, or welding
Machine, machine clip clip connections can be divided into type turn not Saw blade sharpener and two bits, 3 a special type, such as composite cutter knives, suspension type etc. According to the manufacturing tools used materials can be divided into: 1) high cutting tool. 2 cemented carbide cutting tool. 3 the diamond tool, 4 other materials, such as cutting tools, cubic boron nitride ceramic tool etc. From the cutting process can be divided into: (1) the turning tools, especially, inside
Cutting tools, thread, and etc. (2) drilling tools, including drill, reamer, taps, etc. Article 3 cutting tool. 4 milling tools, etc. In order to adapt to the nc machine tool and durable, stability, easy adjustment, can change etc, can be in machine tools clamp are widely used in quantity, the nc tool on the 30% ~ 40%, metal excision quantity of 80 to 90 percent of the total.
With ordinary nc tool used in machine tools, there are many different requirements, basically has the following features:
1 good rigidity (especially rough machining tools), high precision, ant-vibration and deformation,
(2) has good compatibility, quick change,
(3) life, high cutting performance is stable, reliable,
To adjust the size of the 4 knives, to reduce the time for adjust,
5 tools can be reliably broken bits or rolls out scraps of chip, so,
[6], standardization and serialization programming and tool management.
