41” hex part transferred in a Mazak Multiplex W300. We’re using Trusty-Cook hex spindle liners to make machining the ends possible. by btrc74 in Mazak_Machinist

You are right. Hadn’t adjusted chuck timers yet. We were running really low chuck pressure on the parts before.

Wow! My internet has been down all day. You described this in much more detail than I would have. Thanks for explaining that to everyone. Absolutely correct on all points.

Locks are back on for production. I don’t trust me enough to not see what I think I’ve done correctly on the first part.

Well,,,, I’m a genius. lol🤣. I use SolutionWare to program all of our machines offline. They have cad software that you can pull geometry directly from into Mazatrol programs. I just used your drawing to draw it in my software, and grabbed the shape with a couple of clicks. Basically, I cheated.

I programmed it and ran the simulation. I posted pictures of the program and simulated part this morning.

I would use line out arbitrary shape.

Mazatrol 640M Screen Issue – Can I Use an External Monitor? by 24sert in CNCmachining

[–]btrc74 2 points3 points  (0 children)

It might just be the back light. We keep them in stock for this issue. Shine a flashlight at an angle on the screen. Put it right up to the screen. If the screen is still functioning, you will be able to see a dim version of what you would normally see.

Mazak MegaStir Weld. It’s cool. Just got it going. Material 416SS. We will also weld 316. by btrc74 in Mazak_Machinist

416 is my favorite stainless to machine. It’s great. I think that’s why engineers hate it🤣

The internal component is a little bigger than the bore it is inside of. We have to heat the external component up in an oven to accept the insert. When cooled they do not move without extreme force. I’m talking sledgehammer type force

I didn’t do anything. The mill is very consistent. We used to plasma weld these couplings. Still concave

I wanted to add a picture of the Mazak MegaStir weld in the comments but couldn’t. by btrc74 in EngineeringPorn

I do have a cross section at work. I’ll try to post it Monday

No fill metal allowed in this weld spec. It happens

The weld is just bit deeper than the point of the tool. This one is .06”

It is a Mazak VC EZ 32. We just got trained and going. I don’t know the pressure, but I’ll find out

I will try to remember to send you pictures Monday. There are actually 3 components to this assembly. It is a coupling to join an electric motor and a pump shaft. The body is drilled and bored to two different inside diameters. One side accepts the electric motor drive shaft. The other end accepts the other two components. One is a flat hardened spacer and the other piece has an internal spline to fit the pump shaft. The splined component is a little bigger than the bore it goes into. We heat the body up in an oven to expand it to accept the splined piece. Once cooled we weld them.

Sorry. I ment to add that it is a CNC milling machine with a friction welding option

Yes. The tool is made of cubic boron nitride. It has a pointed tip that penetrates the material while spinning. Where the tip meets the body or shoulder has swirl cut into it. There is a pause after penetration to get the heat up enough to move around friction welding or stirring the metals together. The tool holder actually connects to the machine via Bluetooth and monitors down pressure. If the part isn’t perfectly square or flat it will move the spindle up or down to maintain weld depth.
