Title: RDG tools milling machines
Post by: ja2on on April 26, 2009, 08:52:48 AM

You guys have probable noticed the RDG tools now sell milling machines and lathes
and I notice that the two mills at the bottom of this page come fitted with a DRO or power feed

http://rdgtools.co.uk/acatalog/Milling_Machines.html

do they look any good ?

Jason,

It looks very similar to a reworked version of the Chester Champion 20 mill,

Except more expensive.

The Seig Super X3, after fitting DRO and power feed would come to a lot less than the super duper model they are showing.

the x3 is still top of my list I'm just checking out others
I must admit I had not done the maths  ::)

Big problem with a Super X 3 is the spindle motor, just a 1000 W 3 phase brushless motor with variable speed.
It's not a bad motor but because it's a manual machine it 's going to get used with large cutters and flycutters.
Winding to speed down reduces the revs but it doesn't increase torque.
Only a gear or belt reduction will do this.

It's the same motor and drive as in the CNC's but these get away with it by running smaller cutters at higher speed to remove the same amount of work. You never see a CNC using a boring head, they always interpolate with smaller cutters. Whilst the X3 gearbox is noisy and it has a smaller motor it is better at lower speeds.

JS.

I thought the super x3 was like my sieg c4 which has a similar motor and control unit (as far as I know ) ::)
you set the speed you want via the display and the control unit feeds the motor what is required to maintain that speed
overcoming the problems you get with variable speed machines at low revs

please note I could be completely wrong  :lol: I often am

The RDG mills are Weiss WMD25LV machines. I have one of them and they are really excellent. The same machines are sold by Amadeal, Warco, and Chester at varying prices.

I seem to remember that RDG show a DRO on at least one of their machines advertised,

But the price does not include it, yet another does....

Just be aware when comparing prices on what exactly is being offered  :thumbup:
