Problems solved by technology

[0002] In the field of metal cutting, the cutting efficiency of end mills with ordinary structures is poor, and the range of use is relatively small.
Generally speaking, the rough machining end mill is characterized by a large chip space, but due to the large chip space and small core thickness, it is difficult for this end mill to meet the rigidity required for finishing; on the contrary, the finishing vertical The milling cutter is characterized by very good rigidity, but its core thickness is large and the chip space is small. This kind of end mill is difficult to meet the requirements of rough machining for chip containment. Under the condition of removal rate, obtain high surface quality and precision
Especially when machining various cavities in the aerospace field, the amount of metal removal is large, the corners are many during processing, and the feed rate is large, which is prone to strong chatter, and the chips are easy to stick and block the flute, seriously It can cause the tool to break, and the vibration generated during processing also seriously affects the surface quality, dimensional accuracy and tool durability of the part.

Embodiment Construction

[0021] Figure 1 to Figure 3 An asymmetric dynamic balance end mill embodiment of the present invention is shown, comprising a shank part 1 and a cutting part 2, the cutting part 2 includes three outer peripheral cutting edges 21 and a bottom cutting edge 22 connected with the outer peripheral cutting edges 21, A chip groove 23 is set between any two adjacent peripheral cutting edges 21, and the sizes of the adjacent chip grooves 23 are different. The tail of each chip groove 23 is provided with an unbalance control to make the end mill meet the dynamic balance requirements. Step 24, the end mill meets the requirements of high removal rate for chip holding and chip removal through the large chip groove 23, and ensures the rigidity of the end mill through the large core thickness value corresponding to the small chip groove 23, so that the end mill can meet the requirements of high chip removal rate. At the same time, the unbalanced mass distribution of the end mill caused by t...

Abstract

The invention discloses an asymmetric dynamic balance vertical milling cutter which comprises a cutter shank part and a cutting part, wherein the cutting part comprises more than two peripheral cutting edges and chip flutes, wherein each chip flute is arranged between every two adjacent cutting edges, the sizes of two adjacent chip flutes are different, and an unbalance quantity control step which enables the vertical milling cutter to satisfy the dynamic balance requirement is arranged at the tail of each chip flute. The asymmetric dynamic balance vertical milling cutter has the advantages of high metal removal rate and high processing accuracy and satisfies the requirement for dynamic balance.

Description

technical field [0001] The invention relates to a metal cutting tool, in particular to an asymmetric dynamic balance end mill. Background technique [0002] In the field of metal cutting, end mills with ordinary structures have poor cutting efficiency and are used in a relatively small range. In general, roughing end mills are characterized by a large chip space, but due to the large chip space and small core thickness, it is difficult for such end mills to achieve the rigidity required for finishing; on the contrary, finishing vertical The characteristic of the milling cutter is that it has very good rigidity, but its core thickness is large and the chip space is small. This kind of end mill is difficult to meet the requirements of rough machining for chip tolerance. Therefore, the end mill of ordinary structure is difficult to use in high metal Under the condition of removal rate, high surface quality and precision are obtained. Especially when machining various cavities...
