How to select the NC lathe tool

　 CNC tool knowledge
NC cutting tool is a tool used in machining, also called cutting tool. A broad range of cutting tools not only includes tools but also abrasives
At the same time, the numerical control cutting tool is also provided with a knife blade, a knife handle, and the like!
NC tool classification
According to the structure of the cutter can be divided into:
The integral type: the cutting tool is a body, is made of a blank;
Welding type: the use of welding methods, the knife head and knife;
Machine clamp type: the machine can also be divided into two types of non indexable and indexable!
Special type: such as composite cutting tools, shock absorbing tools, etc..
According to the materials used in the manufacture of cutting tools can be divided into
HSS tool;
Carbide tool;
Diamond tools;
Other materials, such as cubic boron nitride cutting tools, ceramic tools, etc..
From the cutting process can be divided into
Turning tools, especially round, inner hole, thread, cutting, slotting tools, such as a variety of;
Drilling tools, including drills, reamers, taps, etc.;
Boring cutter;
Milling tools.
NC tool selection
In the selection of CNC machining tools, should consider the following aspects:
1, the type of CNC cutting tools, specifications and accuracy level should be able to meet the requirements of CNC lathe processing.
2, high precision. In order to meet the requirements of high precision and automatic tool changing, the cutting tool must have high precision.
3, high reliability. It is necessary to ensure that the tool will not happen in the NC machining and the potential defects will affect the smooth processing
And the combination of the accessories must have good reliability and strong adaptability. Precision metal processing
4, high durability. CNC lathe processing tools, both in rough or finishing, should have a higher than ordinary machine tools used in machining
In order to reduce the number of replacement or repair tools and tools, so as to improve the processing efficiency and ensure the quality of CNC machine tools.
5, broken chip and chip removal performance is good. CNC lathe processing, broken chips and chip removal is not the same as ordinary machine tools can be processed in time by manual processing, chip easy
Winding on the tool and the workpiece, the tool will be damaged and scratched the surface of the workpiece has been processed, and even wounding and equipment accidents, affecting the quality of processing
And the safe operation of the machine tool, so it is necessary to have good chip breaking and chip removal performance.
