Common saying says " 3 minutes of technologies, 7 minutes of cutting tool " , seeing numerical control machine the importance of cutting tool also is charging cutting tool is the segment with numerical control important treatment.
The complexity that machines as a result of numerical control (be like different machine tool, different material, different cutting tool, different cutting kind, different parameter set) .
Believe a lot of people can have different view to machining center:
One, Ask: How is system of cutting tool of machining center treatment to comprise?
System of cutting tool of machining center treatment by finished product cutting tool and standard knife handle two parts are comprised. Among them part of finished product cutting tool and general cutting tool are identical, wait like knife of O of the knife of ǐ of X of broach, mill, ǎ that wring Ji, tap. Part of standard knife handle can satisfy a machine tool to change the requirement of the knife automatically: Can loosen automatically on machine tool main shaft and taut fixed position, install all sorts of cutting tool and check well and truly to provide, can get used to the outfit knife of manipulator and discharge knife, facilitate undertake access in knife library, management, carry and identify etc.
2, Ask: How to choose cutting tool material?
To improve productivity, domestic and international machining center is facing high speed, tall tigidity and high-power direction development, this must be had with respect to requirement cutting tool can bear the function of high speed cutting and puissant cutting, and want to stabilize. Same approve cutting tool to there must not be bigger difference in cutting function and respect of cutting tool life. When choosing cutting tool material, choose hard alloy cutting tool as far as possible commonly, nicety bores hole it is better to wait to still can choose property, more the cubic nitrogen of wear-resisting turns boron and diamond cutting tool.
3, Ask: How to use machining center cutting tool?
How using field of machining center cutting tool, we should respect science, handle affairs by cutting rule.
Qualitative to different spare parts capable person, there is quantity of penetration of a cutting tool of speed of a cutting, back, feed on objective law 3 person the optimal cutting parameter that suits each other. This pair of large parts, rare metal spare parts, precious part is more important, should fumble ceaselessly in practice parameter of this optimal cutting.
When choosing cutting tool, the structure that should note pair of work and craft sex are analysed seriously, surplus of combinative work material, semifinished product and cutting tool machine place to consider integratedly. It is after it is good to decide, should mix code name of cutting tool norms, special cutting tool the content list record that this knife place should machine comes down, for be being used when process designing.
4, Ask: What should when machining center place uses cutting tool, the choice notice?
The following respects should note when place of choice machining center uses cutting tool:
One, good cutting performance. Uses cutting tool must be had can bear the function of high speed cutting and puissant cutting. In the meantime, same approve cutting tool to must be stabilized in cutting function and respect of cutting tool life.
As numerical control treatment efficiency rises slowly promotion, the knowledge of commonly used cutting tool and choice are crucial!
