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

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.

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

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

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

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?

General milling machine seems to be a root screw, if the NC milling machine is pneumatic or hydraulic broach device. CNC accessories sold, the package should also have, but very expensive. Not interchangeable by different manufacturers. Structurally simple steel ball with broach claws.

Why is the tooth shape of broach oblique?

Because the broaching method of broach is done by layer by layer, the required inner spline shape is eventually machined out. Therefore, the blade of the broach is tilted from front to back

Microcrystalline stone tile for broach can open it

Microcrystalline stone cannot use the manual machine, so is not open, because its surface as glass, if the cutting or cutting machine, cutting machine with quick tow Microcrystalline stone to be cut, and then began to cut, but on the edge of some edge collapse phenomenon, may not very straight, if some local aesthetic requirements high, the best place to get professional processing of ceramic tile cutting, then the processing plant and a bottom, it will be better
