Hi

Cheers for the continued input guys, yes i could machine the parts needed with just a milling machine. But also could machine other parts that would be quicker on a lathe, the programme that did the milling was 8k lines long just for 3d milling on Heidenhain control. The pics of the said parts are on page 1, that is the biggest part for hobby use that will be machined to date.

But may also want to machine some alloy wheels at some point, so then this would be 100mm dia max again for hobby use.

So what size milling machine now fits the bill, IE next size up from bench/hobby machines. 

Cheers

Les i did look into renting a unit out a few yrs ago, the cost without supply was £165 a week. But yes pretty much want to at least make good money like a second income, something i want to try and thought doing this from home would save money on a unit. If it was successful then move into a unit would be the next level.

Just checked and mine is 80amp i was looking at this but the seller failed to answer my questions **LINK**

Cheers

Well thought i'd update this thread, quotes well sent out 5-6 request and only 2 replies.

1 said need to have VAT number before a quote can be given, also been looking at bigger machines than the hobby level. So asked for a quote to crane a machine over the house, got a reply but wanted full address. After i sent full address nothing.

So just to give me something to do and research more, what is the biggest lathe and mill i could use on single phase power.

Or what machines what fit in this power range

Cheers

Again cheers for all your inputs, I will be sending another quote out next week. Phoned a bloke I use to work with but the guy who does quotes is away till next week.

These quotes I have been getting at the mo are just for turning, I just want everything in place should this be successful and money can be made.

Really comes down to testing of the product from the states, although I can't see it failing but they may not want to pay.
The alloy ones cost £40 with cheap bearings, the cheap bearings are £3 each and take 2.

It's not a matter of doing it for the sake of doing it, I've just never made anything to sell before. And thought it would also be better working for myself so to speak.

My work contracts small work out even if it can be machined I house, because they still charge them self over £100 and hr.
If these can be made with another company, then I see what you saying I should get a large amount for the cost of machines, tooling, software.

Cheers

If this was going to be on a massive production run then no problem, but this is for a wanna be DYIer. IE no point machining parts in a few mins spending more than i can afford on software, tools and machines if the parts only sell on a small scale.

Cheers for the cad/cam info

I have looked at both lathes and mills from that site, been a hobby engineering site what machines do you guys use CNC related that would fit my needs.

Neil

Yes this is an option but finding a machine that can be stripped easy IE 2/3 main parts.

Cheers

Also found a denford cyclone delivered for 4k, but would need a convertor and depends on the quote i get back from the crane crew.

Cheers guys

The first IMG 4 items the top left sizes are

OP1 

1 face up

2 turn dia from 75 to 69.5 +-.1 will be fine to 22.5 long

3 turn 69.5 dia to 24.5 15.5 long .1 tol

4 drill to any size the machine can take to around 17mm 35 deep

op2

turn round

1 face to length 32mm

2 turn 75 to 49.95 +0-0.05 10 long

3 turn 49.95 dia to 21 long +.1-0

4 bore for a bearing 18 dia - 0.025 32.5 long

Turning on a lathe with just 1mm cuts myford ML7, so thought a CNC would handle this just as good. Milling was also just 1mm rough cuts. Finishing was done with a ball nose taking very fine step over cuts to get a smooth finish.

On a scale this is not going to be thousands off, hope so but doubt it.

Mike if you turn 2.6kg in 2 mins down to just 60g, so i need more info regarding machining my parts.

Software i know you can pay 7.5k plus for it, and work pays 5 times that just for the license a year. But the part is not very technical just basic 3d, on another forum a bloke replicated it in just 15mins but used solid works or solid cam

The £30-£40 an hr was just for turning from to local firms, 1 i used to work at was £30 an hr.

I know it's not easy just thought or hoped it would be possible to get these done at home, and based the turning on the turning i did on the manual lath. If these can be made at home in under 3 hrs i can make good money on the orders i have just now, i have 2 parts going to the states for testing to make sure they are bullet prove. I have no doubts about them been has though they are replacing aluminum, just a different design.

The allo 1 weighs 86.5g the Ti comes in at 89g but using Ti bolts takes this down to the same weight as the alloy.

Cheers

New or used as long as it does what i need it to do

Been looking at denfords, boxfords, emco's but finding it hard to get the info i need.

Was even looking at a denford cyclone and having it craned over the house, just waiting on a quote. But this 1 i have seen is 3 phase, not sure if they are all 3 phase or if a simple convertor would allow it to run on single.

Cheers will looking into this and email

thanks

Post above gives the size i need mate, plus my opening post.

Neil cheers i have looked at this X3 and although it's only little too big, it just will not fit.

Bob

Yes i have had a few quotes but £30-£40 an hr is just silly money, the price goes up with been Ti. I can make these on a manual lathe in an hr or so, small hobby CNC half that time. Milling at work was just over an hr, but limited in spindle speed of 1500revs so was longer than it should have been.

I can get away with milling these at work, i did 3 on a night shift but asked the gaffer and he thought i was doing 1. I even asked what the rates was for me to pay work but £110 it's not going to happen.

TBH Im more concerned about what lathe to buy TBH, can't mill them if i can't turn them. But CNC is really a must, manaul is OK for 1 offs even a few but a production run has to be CNC.

But when it come to small CNC lathes it becomes more limited in the max turning Dia, and 75mm is needed.

Cheers guys.

Cheers

I need a CNC mill and lathe, i no this has prob been covered many times but i'm limited in getting the right machine down the side of my house, i have just 790mm but this opens up to 1300mm after just 10ich or so.

I have recently sold a myford ML7 after i made some parts, but these parts are now wanted on a large scale. These are for RC hobby use, but the market seems good and people like what i've made.

The size of the product in stock billet form is 75mm dia 70 long for the lathe to turn, i need CNC for speed and repeatability. It will also be cutting Titanium mainly but also aluminium.

Converting a manual is not really an option, unless i pay somebody to do the conversions.

I need to know what CNC mill and lathe would be best for my needs, tolerance +- 0.05 on both machines max.

I don't want to import an machine due to the cost of importing, max budget for both would be 8-10k this would need to include CAD/CAM that can do both 2D and 3D milling, basic for turning and could program this myself on Fanuc.

The CAD/CAM also needs to be user friendly because never used it before.

Thanks
