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:CNC Lathe Feed base surface is floating, there is no good way to solve?

I've been troubled by this problem for a long time. Just as if the needle and double processing, the depth of the top pinhole inconsistency is unable to determine the base. It's impossible for every piece of work to have a knife once,

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

I have a good 5.6 sips of rifling

Q:Why don't carbon tools steel be used to make Broaches and gear cutters?

Carbon steel is of high hardness, wear-resistant and difficult to heat deformation

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?!

The rotary joint is connected and air cooling water in the water and gas into the rotary joint before all the way with the on-off valve, OTT rod which is provided with holes, similar to the valve, the locking rod cutter, shift lever, waterway connected, pneumatic on-off valve closed, the water is turned on. The coolant through the tool cooling hole nozzle. Similarly, when the rod is loose, the pull rod is pushed forward first, the air path on the pull rod is connected, and the waterway is closed, and the cone and the end face of the main shaft are blown and cleaned at this time.

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

The pipe is fixed and the cutter head can be taken into consideration with the percussion drill at the top of the drill bit, not knowing what exactly. Only know that grinding, and pull a tube, do not rub, do not change the knife!

Q:Microcrystalline stone tile for broach can open it

It is best to use the water jet cutting stone ceramics

Q:I am currently in a lathe machinery factory, factory of broaching machine really curious.It is a hole with the kind of cylindrical broach broaching machine, after a day's work is down to a special knife Seurat with special machine tool grinding.Would you please tell me that the diameter of the broach is not smaller since he repaired it? Wouldn't it be possible to process the required size?

Repair is the front edge of the broach, the blade has a wide blade. After grinding, only the edges become narrower and have nothing to do with the outer circle. Unless the grinding too much, will affect the outer diameter of the cutter tooth. However, the last 4-5 teeth of the broach are the correcting teeth for correcting the outer circle, so the sharpening broach has no influence on the final processing size.

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

This is rarely the case. Did you pull the nail in the wrong way?
