First parts off of my new Brother R650X2

I am only running the machine as fast as I can swap parts. I needed to get these parts out the door so I just clamped the pallets on top of the vises and went with it, not ideal! Both the clamps and vises are trying to bow the fixtures. Now that the pallets stay on the table I will be using pneumatic clamping to speed it up, when time permits. Tailstocks and driver plates for the 4ths are next.
The slower feed rate on the first 2 parts with the first tool on OP1 I think is caused by Fusion 360 sketch geometry. The first part is projected lines from the solid, then patterned for the other 7 parts. For some reason, it doesn't like the projected lines and a point. The code looks good to me but I haven't done the math to see if it is correct. Perhaps coded endpoints are off by .0001", I have seen Fusion do that before.

Hi, I just found your Rs650X2 videos and I am impressed with the productivity. I'm looking forward to see more videos, it would be great if one day you would discuss working on Brother in time perspective. I would also like to see the 4th axis work!

[@cgpmachining]

What do you mean "working on Brother in time perspective"? It is currently set up with my first 4th axis job and I have 4 days of work left to do. It's just for stock, the order has been delivered, so I am taking some time off while the weather is good to get some projects done before winter. I will get some videos made before I finish and get them posted. I'm finally running the machine at 100% with the current part since it is the first one where I can swap parts faster than I can get the machine to run them. Some tools are running 500ipm so it will be a far better video to show how fast the machine is. Funny thing is I had one path running at 620ipm but the cycle time was longer than when run at 500, go figure. While I love the machine and am glad I got it, it has made me respect my Kitamura a lot more.

@@cgpmachining I apologize for the inaccuracies. I meant your thoughts on working with this machine on a daily basis, pros and cons, a little information on the configuration. So I look forward to your new videos. You mentioned pneumatic clamping, could you write something more about it? With what accuracy does the machine position pallets?

[@cgpmachining]

@@piotrkarcz6853 No reason to appologize, I just seemed like a translation issue. When I get a chance I will do a video showing all the hidden details of this machine and a bit of a review. It is a rather unique build and one I find quite interesting. The way the 3 axis assembly and rotating table assembly is mounted on the base to allow the chips to get flushed out. The pneumatic clamping will have to wait, better to show it in a video once I get it made. I REALLY want to convert driving screws in and out to pushing or pulling a plunger, it makes life sooo much easier when swapping parts. I haven't checked the table location accuracy yet but think it must be within .0001" based on the tooling work I have done so far. I have been told by others with this machine that they bored a hole, indicated it in, rotated the table around, and when indicating the hole the tenths indicator did not move.

[@piotrkarcz6853]

@@cgpmachining If I understand correctly, pneumatic clamping will be your own design or will you use some zero point solution from the market? Like you, my work space is limited, I built it myself, and also own an older 3-axis machining center. I am slowly looking around for something compact and fast at the same time, Brother speedio or older versions of it might be a game changer for me. At some point, I found that for the moment I need to optimize machining times differently, so I decided on a zero point system from Schunk but lately I've had so much work that I couldn't install it and redo the vices. Do you have an Instagram account maybe?

[@piotrkarcz6853]

@@cgpmachining I referred to change the entire fixture plate. Your comment I believe is about the clamps themselves. Which would be a very interesting solution. I have seen somewhere fixture a plates with hydralic release clamps.

Great company

[@ajfreeze215]

What does a machine like this cost new? I have a VF2ss and a Doosan twin spindle lathe. I think this would be perfect for the parts I make.

[@cgpmachining]

I don't think Yamazen would like me quoting numbers and I doubt they would mean much since it has been 2 years since I bought it so I will refrain. I love the rotating table a lot more than I ever imagined I would, and will never have another production mill without one, unless I have a robot to go with it.

[@skuresture]

Get a quote from your yamazen dealer. They vaty alot dependigt on what spindle and magazine you choose

Hi I commented on your video about the Tormach bandsaw. Looks like you've got a really sweet setup! I was looking at an R650X2 for our production. Did you say you're working out of your garage? Or did I get that wrong. I'm currently using a Haas VF1 and trying to figure out what our next step should be. I'd love to see more of your shop.

[@cgpmachining]

I work from home in a shop I built in 2004. It is 14'x20' inside dimensions and I have my new R650, a 2001 Kitamura 1Xi which is also a 30 taper, computer workstation, and some conter space. Yes, space is limited. I have since built a 8'x12' building for more storage, the saw, and I put my lathe out there to make room for the Brother. The Kitamura is pretty fast but the Brother is definitly on another level and the rotating table takes it up one more level. I had about 800 spindle hours on the Kitamura in 2020 and I figured the rotating table alone would save me around 78 hours just in fixture swaps. Keep in mind it takes me 15-25 seconds of spindle off time to swap pallets in my Kitamura so it isn't slow. On top of this having my fixtures stay on the table allows me to use pneumatic clamping so I can just push or pull a button to activate the clamps, NO MORE SCREWS!!!!!!! So after I get new fixtures made I think I can save several times that 78 hours a year, on 800 hours of spindle time. The Brother is a great production machine, it is specifically made for production, but because of this it will have a lot of downsides for anything other than production. It certainly lacks the balls or guts of my Kitamura. I am desperatly trying to get my work switched over to the Brother right now but once I get caught up I am going to do an in depth review of the Brother. It is certainly a different machine than a C frame and has a lot of interesting features.

[@grappler185]

@@cgpmachining As I looked into the 650X2, I came to the same conclusion, that a dual table would be more of a hassle for testing tool paths, doing short runs, etc. So for now I'm thinking a Haas VF3SS might be good compromise between production throughput and easy access for prototyping. (Have you ever used a Haas? If so how does the Brother controller compare?) Looks like you ship a lot of product. Are you selling your own end-product or are you manufacturing components for someone else? I manufacture and sell a handgun accessory I patented.

[@cgpmachining]

@@grappler185 I have never used a Haas and am sure the Brother control isn't as user friendly. I personally like my Yasnac J300 better than the Brother control. It is much more to the point than the Brother but doesn't have nearly as much capability. As far as a bigger Haas vs an R650, in my opinion it would be an R650 all the way. It would make 3-5 times as many parts at the end of the day if the Haas doesn't have an auto pallet changer, and not much difference if it does. It would also use less shop space, air, and much less electricity. The R650 uses 2 amps doing it's warmup program and not much more when making parts, my phase converter has an amp meter. Yeah, I am making some assumptions on your parts but I doubt I am very far off. I have my Kitamura for any short runs or tooling jobs, and you have your VF1. When running your Haas think about the spindle starting to cut metal on the next op 4 seconds after it stops, while you are opening the door to start swapping parts or fixtures. The R650 has about a 4 second chip to chip table swap, and you don't have to be at the machine when it stops to get it running on the next op. You just need to get the parts swapped for the next op before the machine is done makeing the current ops parts. This makes a huge difference in the number of parts you make at the end of the day. Right now pretty much what I make are all my own designs which I sell to one customer who then markets and sells them. Now that I have the Brother I will have time to get some of the workholding items I have developed for my own needs into production to try and diversify. Things like wedge clamps, as seen in the video, double acting vises including 4 sided to be used on the 4ths, vaccum systems, etc. All low cost by design and probably only sold direct through my website so no markups.

@@cgpmachining I own both Brother R650xd1 as well as a bunch of Haas machines. I wouldn't recommend a new Haas as they have so many issues with lubrication. Ask any of us that own them and had to do conversion kits that cost a bunch of money and down time as well as countless lubrication system empty errors that seem to be never ending. All that a side if Haas ever figures it out the machines are still stupid slow in comparison.

Sir front button view explain please sir

[@cgpmachining]

I am sorry but I don't know what you mean by "front button view"? I think of this as the green button on the machine just outside of where I swap the parts.
