I know, that's exactly what they're charging me depending on size. The larger the casting, the better deal you get. Of course 3500 bucks is obviously going to be a much bigger machine than the SVM-0.
Most of the machining will be done in house. Saves a ton of money, especially when going rate is $90 an hour plus setup and tools etc.......
I'm not worried, my machine is coming along just fine.

Hi guys, I just get some time to update the electric actuator progress.. I got the 2 samples several days ago and the total length is 230mm with 30mm traveling. I then disassembled one of them and found it could be even shorter.. So I retrofited it to less than 150mm with 8mm traveling. I think it should be the fitful size now.

Here are some pictures taken at that time. I've designed the mount bracket and are making it now. will show again on SVM-0 once finish it.

Good things is it seems smaller than what i expected

[asuratman]

That fit the small machine nicely, not too high/long. Have you tested for reliability?

Defeng that looks pretty good....

[handlewanker]

Hi D, at 150mm that's pretty compact........now we need a price......LOL.........the painful bit, but in place of the air cylinder type, this is the way I will go........the family jewels once more get to the pawn shop, they have a special shelf reserved just for them.

It looks like the stainless steel belt cover will have to be modified or remade........sigh.......it looks so good on the machine at the moment......never mind, definitely a step in the right direction.......I can almost hear it go.... click on, click off, which is a whole lot better than.... puff puff....whirr whirr , bump, bang, crash for the air one.......just my opinion, no comments.... PLEASE........the sound effects are all the allied parts that combine to make an air cylinder work.

If you don't want a comment, don't post in a public forum.

It also helps to base your opinion on facts presented to you. It's both arrogant and ignorant to claim that a single person knows better than the well established consensus of the industry. The only argument that I have seen that somewhat validates your claim is for the users who don't have access to compressed air. The fact that most CNC machines use either pneumatics, hydraulics or a combination thereof should not alone be enough to disprove your claim, but it does carry some weight.

With that said, I do understand why Defeng is exploring this option. The average hobby user might not have access to compressed air, or the use of compressed air introduces other difficulties in production. That doesn't make it the best possible choice, but it's a good candidate.

[handlewanker]

Hi.....most people can afford about $100 for a hobby compressor for home work shop use, the type that has the motor and compressor direct coupled etc to a 50 litre tank.....belt drive models cost anything from $250 or more.

I prefer to have an electric solution if possible,.....I do have a compressor....... even if the whole damm World uses air to push their draw bars down.

When I come to fit the mist coolant I'll probably need to have some kind of air supply......but I'll work on that one when I come to it.

Now all I need is for Defeng to quote me a price and I'll be placing the order......that is definite.......he also offered to fit it before shipping........win win for me.

Been working on the G code tuition videos on UTUBE.........I get the impression that thread milling is the same as boring a hole from the bottom up with a single pointed tool and a coarse feed rate.........that seems simple enough......who needs a $50 special thread milling tool.

It might take longer than the commercial item, but it'll get there the same.

The beauty is you can thread a hole with the same tool and pitch for any size hole, and it's quick too......no more broken taps etc........I wonder if you can thread a tapered hole?

Hi asuratman,

I have not tested it on machine yet but just connected power and it could run as expected.. I will get the bracket done very soon and then start the reliability test.

Hi Ian, no rush about the pricing Let me test it firstly to make sure it will work and work reliable...lol

I think "The Blight" get the point of this small device-- for those users don't have an air compressor or not convenient to use it.

Thanks to all of your guys! I post a little slower recently for many small stuff need to be worked out quickly.. I do gathered many things waiting to be posted...

[handlewanker]

Hi D......I'll wait to see what your R&D testing gives........seems to be an ideal set-up, I think despite what some of the people on here say it will be popular.

I don't know what your preferred attachment method to the mill head will be for the PDB, but as a suggestion if it could be attached to a clamp ring around the mill spindle top then this would enable it to be permanently attached to the mill spindle even when the spindle is changed over making the settings for activation easy to maintain.

Hi Ian, that's pretty much I planed for it..lol And I think it's the only right way now to do it for now because the split head box is not good to set up the PDB

[louieatienza]

Defeng, with a floated actuator design you won't have to worry about the split head...

[handlewanker]

Hi, sounds good Defeng........I realised some time back when looking at the head with the split, making it a separate and loose entity, that to mount the PDB otherwise would have been a problem when the head was slackened to remove the spindle.

At any rate, before the PDB was in the picture, when I opted to have the ISO20 spindle it became apparent that a PDB mechanism was (definitely) needed, so I designed something to cater for that problem........it was a lever device with a stepper motor and screw etc...........details of which are purely hypothetical without having the head casting and spindle before me to ascertain the design and mounting set-up.......not as neat as the electric actuator, and a possible solenoid solution was also in the picture.

The fact that the drawbar is pressurised with Bellville washers to exert the 800 lb pull is a curse that won't go away.....just a cross to bear no doubt.

As a matter of interest, the draw bar for the SVM-1 and 2 would also need about the same pressure to retain the tools too, so the electric solution "could" also be a neat one......for those liking electrics etc......LOL.

I think also a pneumatic solution would have to be mounted in the same way, so for those that like a bit of air, it'll keep them happy too.

Hello Defeng/Skyfire and everyone else,
Been a while since I have posted here, but such is life, time is a rare commodity in the life of a regional tech specialist. Blah, Asia Pacific is a busy one...I still not have made that much progress on my BF46 Vario and I doubt I will have time for that in the near future.

With that in mind, I have sent the following email to Defeng last night, hope he sees it and hopefully he will allow me to go down this path

Eagerly awaiting your feedback!!

Hello Skyfire,
I hope you don't mind me calling you this

I have read your worklog when you first started your first prototype ICNC over at CNC Zone.

The end result was great, and I have also a nice Optimum BF46 Vario that I want to convert to linear ways and CNC at some point in time.

Now, I have a very special request, and as a fellow hobbyist, I hope you can consider my request.

I would like to buy a complete machine from you, but no wiring, motors or electronics.

I have very nice brandnew DMM Tech 750w servomotors, as well as drive controllers, and a Mesa board parallel port interface. Software I have Mach 3 and Mach 4, as well as enough computers to power NASA.

So I only need the complete machine from mechanical perspective, but would like to fit all my own electronics, as I am an automation expert, this leaves at least some part of the hobby for me. So I can do wiring,

If it is possible, can you give me a price in such a unit? I expect you will add a little extra margin, no problem.

Please let me know also shipping cost to Melbourne Australia.

I really look forward hearing from you in this matter.

Kind regards,
Phillip aka mrbean from CNZ Zone.

I purchased my SVM-0 sans electronics, hope Defeng can accommodate you as well..

[MrBean_pm]

Cheers Louie, thanx for the feedback!

This is indeed good news, I am hoping to get the bare machine only, and possibly an ISO 30 spindle, possibly the spindle motor, let's see how things work out.

I have a few dollars extra to spent in this, I am hoping Difeng would be willing to accommodate me, otherwise I would probably then have to convert my BF46 to CNC. SMV-2 makes more sense, and I can keep the BF46 as a manual Mill then, or sell it. It is a great machine that one, good quality German engineering, solid as hell, but I like the work Difeng has done on those series, and the amount of customization, even after receiving the unit, one can do.

Have you received yours yet Louie?

Thanx for the messages also guys, appreciated.

Kind regards,
Beano
