NAEROK RDM350M Milling machine power feed

After much research and time spent on ebay I picked up my first milling machine yesterday. It is a Naerok RDM350M and I got it for a good price with lots of tools. I am pleased as I wanted to go for a larger machine and this is definately big enough for what I want to do. Since I began looking in to these machines I have seen that power feeds can be a great help, especially for some of the stuff I want to do. Does anyone know what type of feed would fit on this machine, and also where I could get one from?

Many thanks

Tom

Can't help with your specific query but I've had a Naerok bandsaw for over tenty five years and despite the name being 'korean' spelt backwards, it's done stirling trouble free service.

The mill is around that age to and excellent quality. The guy who had it before was an old boy who recorded every single thing he did to it!!

Axminster Power Tool sell a small power feed unit. Look at RF power feed unit for example. You will need to ensure that you can couple it up to the Naerok.

My Rexon RDM 400 (round column) has a power feed I built about 10yrs or so ago, basicly its a Lukas windscreen wiper motor, with a 10 tooth sprocket on an extension of the wormwheel shaft, driving a 20 tooth sprocket on the lead screw on the mill, its a bit rough, I threw it together in about 2hrs (intending to rebuild it a bit neater at a later date). I have a low voltage power supply around the workshop, and it runs on this. I only have 3 speeds, controled by resistors via a home made rotary switch. Ian S C

I have a RDM 350 milling machine and would like to fit a vertical mounted digital read out, has any one all ready done this,and are there any problems to be over come particularly on the mounting. Also, just in case type of thing, has any one replaced the column bearings.Ted

You do realise this machine is the same stable as the warco major and minor and equivalent badged products from excel and axminster and chester and...... ? So your searches can be much less maker specific whether it is attachments or parts.

There is another thread runningon the amjor mill from last week too.

Tom,

If you like to think about making your own, like IanSC, there have been articles in MEW.

In issue 50, Stan Wade shows one he made for a Sharp vertical mill, and in issues 14/15/16 Dave Machin made a more complex (to make) one for his Westbury mill.

Either could be scaled for different machines

I have seen one to Stan Wade's design on a typical Mill/Drill, and it worked well.

A good PSU for 12 volt supply is one of those as fitted to campervans, give 12 volts at around 10 amps.

Like Ian SC, I made my own (using a 24V window winder in my case). If you go the DIY route, there are pics of my feed in my album here **LINK** . A variable voltage power supply (0-15V for a 12V motor) is helpful, as it allows you to change the feed rate to suit the job.

I now have a Bridgeport clone so haven't touched this machine for ages. I do remember though that there are power feeds available for the X direction but they cost almost as much as the machine was worth, hence the DIY solution. Depends how rich you are feeling!

If you do a Google search on "power feed mill drill" you will see that generally, feeds for this kind of machine are based on the power feed units that were developed for Bridgeport type machines, modified (fitted on their side) to fit onto the ubiquitous mill drill. So if anything they are more expensive than the original Bridgeport part. they are derived from.

I see that Chronos sell Vertex power feeds (decent Taiwanese brand). For the std Bridgeport application they seem to be about 240 pounds. For the mill drill, they are 270 pounds which sounds about right. **LINK**

I bought one of THESE for my Warco round column mill some years ago. It works very well and I'm pleased with it. The price though is a bit eye watering - I don't remember quite how much it was at the time but I guess, with the rate that prices keep rising, somewhat less than the price shown now!  So the cost is about the same as the Bridgeport version when you add the vat. ( I think it was, yet again, a Christmas present from my wife - strange how she always knows just which bit of workshop kit I " need "!)
