Q:Know how to draw Broaches for involute internal spline parameters

To pull or spline spline, spline parameter is of course laane for internal spline broach;There are many factors in designing broaches, such as machine tool chucks, maximum broaching length, dimension and so on;General to broach company can do, they know how to do, need what parameters will call you to provide

Q:Hope to find a complex tool to do good enterprises, especially broaches do good, quality and Harbin first tool factory and other veteran manufacturers almost or almost no, but the price is relatively cheap, a lot of, thank you

The tools of the Han River are made of broaches. What tool do you want, you can ask me.

Q:5.6 small caliber gun rifling production line with much manual broach

The general value of deep rifling line diameter of the gun bore 2%. 5.72 or 5.75 arrows that broach,

Q:Ask, what does broach mean?

Each department has its own general skills, general skills of broach is gold system, can increase the damage of broach,

Q:Is there an expert who knows the broach?!

A machine tool spindle broach mechanism, a spindle is in threaded inside a broach broach rod is connected with a rod, claw clamping device for clamping or loosening cutter, broach rod sleeve is provided with a force pushing device, force pushing device comprises a pushing rod and a wedge block, wedge block with double the inclined plane respectively a wedge-shaped groove and a push rod and inclined broach rod are wedged, to pull the rod with tight broach, forcing a push device component section shape is round, can keep dynamic balance and achieve good purpose of high-speed operation.

Q:How to solve tooth strain of involute spline broach?

Before broaching, you should check the verticality of the drawing fixture relative to the broach, otherwise the tooth side will easily strain

Q:Why is the tooth shape of broach oblique?

The tooth is made oblique in order to make the broaching cutter tooth is smooth, continuous in withdrawing from participation in the cutting, does not appear at the same time the whole circle cutter tooth cut, and the exit, so as to avoid broaching in appeared in the process of broaching flickering phenomenon, so as to obtain good cutting surface, too to improve the service life of the broach broach. But make oblique to the high cost.

Q:Pull the rifling when rotating or broach tube rotation or both rotation??

The pipe is fixed, and the broach rod moves along with the threaded guide rail to drive the broach head with a certain deflection angle.

Q:Microcrystalline stone tile for broach can open it

The microcrystal surface will collapse

Q:Machining center spindle broach can not reach the designated position, how to adjust?

Transfer the nut of the pull rod and remove the main plate
