Broaching Taps

Broaching taps trapezoidal, square, triangular, single-head or multi-head inner thread can be processed. Once in the lathe, broaching forming, high efficiency and simple operation, stable quality.

Broaching taps working as shown. First workpiece set into the pull cut broaching taps leading part, then the workpiece clamping bolt to broach links with the turret to prevent rotation of the broach. Broaching right hand thread workpiece driven by the lathe spindle reverse rotation, pull the knife along the thread lead is moving toward the tailstock. The broaching taps pull out the workpiece, the screw holes on the processing is completed.

Broaching Taps Working Diagram

Broaching taps are essentially helical broaches. Broaching taps structural design and geometric parameters choice are combination of broaching taps, shovel tooth form cutter, and broach the three tool design method. Wherein the threaded portion of the parameters, the cutting of the broaching taps angle, the calibration part toothed belong trapezoidal taps parameters. The posterior horn shovels to cut the amount of rake angle and profile angle correction shovel teeth forming cutter design method. Head, neck, and the guide part of the design are similar to broach.

Broaching taps general tooth lift amount is 0.01 ~ 0.02mm, rake angle γp = 10 ° to 20 °, after the angle αp is = 4 ° to 5 °. When the selected slot number Z, you can calculate the cone angle 2φ, the length of the cutting part ι1, shovel cut the amount of K cutting parameters. The length of the calibration part (4-5) times the pitch. Trace being made ​​to improve accuracy, broaching taps in diameter taper (approximately 0.5mm), part of a cutting pattern of the cutting cone as shown. The have tiny cutting margin of the side edge of each tooth, in order to ensure that the profile accuracy and surface roughness of the flank. This is one of the important characteristics of broaching taps designed.
