Abstract
The utility model discloses a three-face-blade broach which comprises a handle portion (1), a neck portion, a front guide portion (3), a cutting portion (4) and a rear guide portion (5). The cross sections of the front guide portion (3), the cutting portion (4) and the rear guide portion (5) are in rectangular or square shapes. The cutting portion (4) has three cutting faces, cutting teeth are arranged on the cutting faces, the cutting teeth are of wheel cutting type structures, the rise per tooth of the cutting teeth is 0.10mm to 0.15mm, cutting tooth chip pockets are in lengthened tooth pitch types. Compared with the background art, the three-face-blade broach is high in accuracy of processing surfaces, can achieve good planeness, can effectively improve processing efficiency and simultaneously reduces processing cost.
Description
Technical field
The utility model relates to a kind of broaching tool, especially a kind of three sword broaching tools.
Background technology
Consult illustrated in figures 1 and 2, orthogonal three faces 1 ', 2 ', 3 ' of inside workpiece in the manuscript 2 in the prior art, with machine tool processing, not only inefficiency, and low precision.
