Embodiment Construction
[0014] The invention provides a step forming reamer for three-dimensional cutting, which is suitable for the field of cutting tools. The present invention can be implemented in the following ways:
[0015] Such as Figure 1-2 As shown: the cutting structure 2 is arranged on the front part of the body 1 in a circular array around the axis of the body 1, and the cutting structure 2 is composed of a first cutting part 21, a chamfering cutting part 23 and a cutting part root from front to back. Composed of pillars 22; the diameter of the cutting part root pillar 22 is larger than the first cutting part 21, the cutting part root pillar 22 does not participate in cutting the workpiece, and the rear part of the cutting part root pillar 22 is connected to the body 1; the chamfer The cutting part 23 transitions from the first cutting part 21 to the outer surface edge of the root column 22 of the cutting part in a straight line; the front edge of the first cutting surface 211 is provid...

The invention relates to the field of cutting tools, and provides a step forming reamer for three-dimensional cutting. According to the technical scheme adopted by the invention, the step forming reamer for three-dimensional cutting comprises a body, one end of which can be connected to processing equipment, wherein a plurality of cutting structures which are arranged at the periphery of the axisof the body are arranged on the body; each cutting structure comprises a first cutting part arranged on the end part of the cutting structure, and the rear part of the first cutting part is equipped with a cutting part root column which is connected to the first cutting part, and has a diameter greater than that of the first cutting part; a chamfering cutting part for chamfering a slot-milled edgeof a workpiece is arranged between the first cutting part and the cutting part root column; a first cutting surface is arranged on the front surface of the first cutting part, the front-end edge of the first cutting surface is equipped with an end head cutting edge; and a chip groove is formed between adjacent cutting structures. According to the scheme adopted by the invention, the step formingreamer can accomplish three-dimensional processing of a flat surface and a side surface, avoids replacing tools frequently, and improves processing efficiency.
Description
technical field [0001] The invention relates to a cutting tool, in particular to a step forming reamer for three-dimensional cutting. Background technique [0002] In the process of cutting tools, for enterprises, efficiency and time are the cost, which determines the level of profit; for the process of cutting workpieces with reamers, different reamers need to be used for different requirements of different positions in the processing process , The process of production replacement will waste a lot of labor and time, reducing work efficiency. How to realize the processing of multiple situations on one reamer without replacing different tools has become a long-term research direction. Contents of the invention [0003] In order to solve the existing deficiencies, the present invention provides a three-dimensional cutting step forming reamer, which has a reasonable structure and can complete multi-process processing, including three-dimensional processing of sides and plan...
