milling machine power feed

Hi, I have an Axminster RF30 mill and was wondering if there were any articles that anyone knows about from MEW that describe the making and fitting of a power feed, either for this mill or some that could be adapted

cheers

Hi Dougie, ( you sound as if you could be Scottish ?)

 

You will find an article on fitting a home made power feed to a mill like yours ( I think ) on the following link.

Good luck, enjoy.

Hello Dougie,

 

A partial answer really. I am about to start on a power feed for my RF25 (also from Axminster tools) and am listing the work done on my website http://www.mikes-models.com/powerfeed.html when I have done some that is. I only mention it here since my method is using a 12 volt windscreen wiper motor but after struggling for a while on how to power the motor with variable speed I found the Proxxon power feed (see my website).

 

If you want to email me re my approach you can do so via the website above.

Hi Dougie,

 

Trust the field gun is coming along nicely.

 

We have the Axminster power feed unit fitted to our Warco mill, we got it off ebay quite cheaply a few years back.

 

You are welcome to look at it if it helps.

The one thing about the “real thing” is it does have a speed control, quick disconnect, and a rapid transverse – all of these would need to be done as well – not just the mechanical aspects if you make your own.

Hi Dougie,I built one in a few hours,its crude,its simple and it works for me.Motor,an elderly Lucus windscreen wiper motor with the shaft from the wormwheel extended about 1″ outside the case to take a 10 tooth sprocket.Next a 20 tooth sprocket fitted to(in my case)to the lefthand control wheel.The motor fitted to a bracket that is bolted to the T slot that runs along the front of my machine.A switch fitted,center off,left-right on,this wired to give foreword and reverse.The two sprockets joined with a loose fitting bit of bike chain(so you can just slip it off)My power supply is from an old Zerox copier,the transformer is about a 7″ cube,a battery charger would do nicely.Thats about all,I only had to make one of the sprockets-the 10T.Speed control came a wee bit later,its a home brewed rotary switch with three contacts and resistors,bits of Nichrome wire.No electronics,you can make a guard for the chain.Ian S C

Thanks for the replies, I’m going to follow Mike’s progress on his link above and check ebay like Julie suggested

Once again

Thanks

Just to round the circle, my power feed has been completed and works very well. For more information go to my websites mikes-models.com and my blog

Hi Dougie,

I have fitted a powerfeed to my X1 mill. I think the principles could be readily transferred to other mills. Futher details are here:

Hi All. Re the use of a windscreen wiper motor for table feed. I used a circuit (widely used I believe) that uses a 555 timer device and a mosfet transistor to get variable speed. Works well with a reduction drive to the handwheel shaft. With a bit of thought the reduction drive can also acts as a clutch. A bit elaborate for some perhaps? Anyway my recommendation re using these motors is to sus out the maximum voltage and use that to get a fast return feed. I beleive that 15 volts is the nearer this than 12 volts. I also believe that a windscreen wiper motor can be stalled without burning out!!!! I have done this several times with no problem.

I used an old wiper motor as well with a 2:1 reduction drive on my Warco WM16 mill.For the speed control I found a vairiable speed controller from Maplin electronics,powered from a battery charger.I found that a 2200 uf capacitor across the output of the charger gave me a smoother current for the controller,this has worked well for the last 3 years.

 

Regards Pailo.

hi all,

I used a 12v dewalt cordless drill with a pwm controller on my x3 mill.

 

kind regards
