BB Rotary Broach

Broaching tool is a simple cutting tool, which can be split into regular or irregular polygons on blind holes or through holes, sharp edges or chamfering edges, in addition to standard hexagonal and square holes, they can also be used as grooves, stars or other special shapes.

Suitable for general lathes, CNC automatic lathes, comprehensive processing machines, drilling machines and machines with special functions. It is also suitable for punching various standard or special internal and external holes.

Material

①HSS-Co M35
②HSS-Powder metallurgy high speed steels
③Tungsten Carbide

*Some sizes need to be customized in about a week
1/16''=1.62 , 1/8''=3.26 , 3/8''=9.6

Drill Hole

The normal drilling of the hexagonal hole must be slightly larger than the effective size of the two-phase plane to which the hole is broached.

Hex S=6~10mm, allowable tolerance +0.06~+0.12mm

Generally, we suggest that the depth of drilling is 1.3 to 1.5 times of the depth of broach hole.

Rotating speed

The principle of BB rotary broach allows it to be applied to high rotating speed, from 600 to 2000 r/min minutes, because rotary speed does not affect the cutting speed. However, at very high speed, when the processing starts, the punch will rub with the workpiece until the speed is synchronized. In this way, it is very easy to wear out the punching knife in advance when using the small punching knife frequently. In order to avoid this phenomenon, it takes 500 r/min minutes at the beginning and the feed is 0. 1mm/turn, when the punch enters the working state, increase the rotation speed.

Feed

The selection of feed is based on the characteristics of the material. In medium carbon steel, if the machine has enough thrust, we suggest that the feed rate of each feed is 0.03~0.06mm. In copper and aluminum materials, two or even three times of the feed volume can be used. In the processing of large axle size and hard-to-cut materials, the feed rate must be reduced by 0.01mm.

Through Hole and blind hole

Generally, there is no need to consider the problem of chip removal when passing through the hole, as long as the depth is noted and the punch is long enough to be customized.

After the blind hole is reserved enough depth, the hexagonal hole should be punched. After the hexagonal hole is finished, the inner hole should be drilled with the drill bit of the previous base hole to discharge the residual debris. Note that the drill bit should be at least 0.1mm smaller than the side of the hexagon, and it cannot touch the inner wall of the hexagon when drilling chips.
