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

Are you going to pull the spline or external spline spline parameters is of course laane internal spline broach to do;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:CNC Lathe Feed base surface is floating, there is no good way to solve?

A base level is processed in advance

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 tool steel is cheap and easy to forge, and its machinability is better. The main disadvantage of carbon tool steel is its poor hardenability. It needs water, brine or alkaline water quenching. The tendency of distortion and cracking is great, and its abrasion resistance and thermal strength are very low. Therefore, carbon tool steel can only be used to make some small hand tools or woodworking tools, and the accuracy requirements of the small cold is not high, simple shape, small size, light load of mold, such as used in the manufacture of small punch, scissors, die, cold die etc..Broaches and gear cutters are usually made of high speed steel

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

The broaching mechanism is an automatic tensioning and automatic releasing mechanism for the main shaft of a small numerical control machine tool.principleBy pre compressing the disc spring, sufficient upward broaching force is produced. When you need to change the knife, a knife loosening signal control system, through the electromagnetic reversing valve to control the hydraulic system, hydraulic cylinder pressure oil system will pass into the upper end of the main axle on the chamber, the piston pushing broach parts move down, continue to compress the disc spring, handle downward movement, and through the tool changing manipulator with complete change knife. At the upper end of the cylinder, there are two proximity switch to detect the cylinder piston is in place; if the cylinder is not in place, then the two proximity switches will not signal the NC system will not continue to the next procedure, to ensure the safety of CNC machine tools.

Q:Is this a standard part, or is it only required to buy the finished products from other factories, or do you want to design and size it yourself?

Standard parts can be purchased. It is better to bring the old parts with them or to provide the corresponding machine tools

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

The barrel to fixed wire using rotary broach rifling

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?

The spring mattress on the pull rod in the spindle is broken, so replace it all
