CNC machining center in Xin famous processing most often and most headaches is flutter.
Why attack flutter has the following main points: the machining center
1, what system comprises a knife handle, rigid, boring bar, boring head and middle part of the rigid connection. Because it is the cantilever processing, especially the small holes, deep holes and hard work piece, the rigidity of the system is particularly important.
2, the dynamic balance of the system with respect to the rotation axis of the system of things, the thing itself, such as there is a balance of mass, in the rotation of the centrifugal force due to the role of the imbalance caused by the onset of flutter. Especially in high speed machining, the dynamic balance of the things have a great impact.
3, the workpiece itself or the workpiece fixed rigid, like some of the smaller, thinner parts due to the lack of its own rigidity, or due to the shape of the workpiece and other reasons can not be used reasonable fixture with plenty of fixed.
4, the shape of the blade tip blade shape, rake angle, angle, nose radius, broken flute shape will cause the cutting resistance is also different.
5, the selection of cutting parameters including cutting speed, feed, feed and cooling mode.
Rigid linkage between 6, the machine spindle system of machine spindle rigidity, bearing and gear and spindle and handle.
Above is "CNC machining center in the boring processing attack flutter problem the reason of a detailed explanation, expect to help and look forward to everyone to come together to discuss the related knowledge of the CNC machining center.
