Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] Embodiments of the invention include:
[0024] A processing technology for a small-diameter spiral flute tap, comprising the following steps:
[0025] a. Select a long bar, wire cut it to make a blank, and heat treat the blank in a high-temperature furnace. The heat treatment step is to quench first and then temper 5 times. The quenching temperature is 1190 ° C ~ 1200 ° C, and the tempering temperature 590℃~600℃, the hardness of the blank after heat treatment is HRC65.5~66;
[0026] b. Carrying out through-g...

Abstract
The invention discloses a technology for machining a small-diameter spiral fluted tap. The method comprises the following steps of a, manufacturing a workblank, and conducting heat treatment on the workblank; b, conducting continuous grinding external circle machining on the workblank obtained in the step a; c, grinding the tips of the two ends of the workblank obtained in the step b on a sharpening machine; d, conducting handle-portion squaring grinding machining on the workblank obtained in the step c on a squaring grinding machine; e, conducting blade-portion external circle and handle-portion external circle rough grinding machining and fine grinding machining on the workblank obtained in the step d, and obtaining a semi-finished product; f, conducting spiral fluted grinding machining on the semi-finished product; g, conducting threaded grinding machining on the semi-finished product obtained in the step f; h, conducting cutting cone relief grinding machining on the semi-finished product obtained in the step g, and obtaining a finished product; i, detecting the finished product in the step h; j, conducting rust-proof treatment, signing, packaging and delivery. With the mode, the small-diameter spiral fluted tap with the M of 0.8-4.0 can be manufactured, the quality is high, and the application is wide.
Description
technical field [0001] The invention relates to the technical field of metal cutting tool manufacturing, in particular to a processing technology of a small-diameter spiral flute tap. Background technique [0002] Spiral flute tap is the most commonly used thread processing tool, which belongs to a kind of tap. It is named because its flute is helical. Spiral flute taps are divided into left-handed spiral flute taps and right-handed spiral flute taps. When processing a right-handed thread, the chips are discharged downward when the left-handed spiral flute tap is tapped, which is suitable for through holes; when the right-handed spiral flute tap is tapped, the chips are discharged upwards, which is suitable for blind holes. At present, the processing technology of large-diameter spiral-fluted taps in China is very mature, but there is a lack of processing technology that can manufacture small-diameter spiral-fluted taps. Contents of the invention [0003] The technical pr...
