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 parameter will provide.The spline joint is composed of inner spline and outer spline. The internal and external splines are all multi tooth parts, the splines on the inner cylinder surface are internal splines, and the splines on the outer cylinder surface are external splines. Obviously, the spline connection is the development of the number of flat key connections. Splines are standard structures.

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?

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

Because of its hardness is too high, easy to crack, and if you do gear cutters and broaches, not only a few times will collapse.Therefore, Broaches and gear cutters must be cemented carbide.The carbon content of carbon tool steel is high, between 0.65-1.35%, and belongs to sub eutectoid, eutectoid or eutectoid steel. The carbon tool steel can get higher hardness and wear resistance after heat treatment, and the core has good toughness. The annealing hardness is low (not more than HB207), and the processing performance is good. However, when the working temperature reached 250 DEG C, the hardness and wear resistance of steel decreased rapidly, the hardness decreased to below HRC60, and the hardenability of this kind of steel was low. Larger tools can not be quenched (water quenched by 15mm), and when water is quenched, the hardness of the surface hardened layer differs greatly from that of the central part. Cause the tool to deform easily when it is quenched. In addition, the range of the quenching temperature is narrow and the temperature should be strictly controlled during quenching. Prevent overheating, decarburization and deformation.

Q:Ask, what does broach mean?

Gold is a skill with physical attacks, called with tremendous effort

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:How to solve tooth strain of involute spline broach?

Workpiece hardness of less than HRC30 is generally broach problem, of course, there are special. It should be cool under normal conditions. I personally do Spline Broach Design and grinding parameters, then the workpiece interested told me to give you the design drawings for reference

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:Microcrystalline stone tile for broach can open it

The microcrystal surface will collapse

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?

The required size is guaranteed by the calibration teeth. Usually, the calibration teeth are not repaired or only very few allowances are made, and not all the calibration teeth need to be repaired at any time.
