Interesting to note Chester have free delivery on that. Used to be extra from them. Maybe finally catching up with others.

Note the warning at the bottom of the chester page about continuous running -not. Applies to the others I expect but might be relevant for your CNC ambitions.

Did you also check Warco?

These are not in any way like for like. The chester is bigger than the amadeal which is bigger than the emco. Mostly people fix a budget or a size then ask for comparison on the finer details from suppliers.

The Warco VMC is very popular and similar budget so would be my choice over these but that is easy to say when I'm not in the market for a mill.

Mozbo, you're suspicions about them all being from the same place may be true, but it's clear that individual vendors do put their own "stamp" on things which can be very significant in some cases, it's a case of carefully comparing specifications. (It's sometimes not just colour, bigger motors, longer tables or metal gears rather than plastic, all sorts)

You many find this page of considerable interest being that you've flagged up 3 machines from the same manufacture…….. http://www.weiss.com.cn/product/&pmcId=59.html

other Chinese machine manufacturers worthy of mentioning which may help you with your research are Sieg and RealBull (who share many castings with Weiss)

you can see from the manufacturers page that the WMD45 (suspiciously similar to the Chester Super Lux, and G0761!!) is considerably higher up the ranks than the other 2 machines (WMD20 or 25, similar to G0704 which are basically both the same) –  it's also WELL over 250kg (double the others) so in terms of size and ability it simple outclasses the other 2 more portable/manageable machines, it seems to be a superb price at the moment.

I find it helps to search for Grizzly's name ie G0761 for the Chester Lux or G0704 for the other 2 as the Americans seem to do a lot more user reviews and YouTube videos here's the grizzly mills home page, they sell almost every rebranded mill from all the Chinese manufactures http://www.grizzly.com/products/category/480000%7C700002

if you might want a lathe further down the line, an MT2 or MT3 spindle might give your more cross comparability with tooling than R8 – and often the machines are available with any you like if you just ask the vendor (hence they often put a ** next to it)

No trouble, if your anywhere near Harrogate weekend after next it would be useful to drop in to The Harrogate Show most of the major suppliers will be the and you can get hands on and have a look at all the machines, alternately if your the other end of the country I hear Amadeal are very welcoming and helpful.

just worth mentioning….. That Super Lux, being one monster of a machine…. Is it single or three phase, it doesn't exactly like a bench top machine at 250kg, Amadeal sell one too called the AMA45A and it's 3 phase, you get a better appreciation of its size from their pictures.

I went with the WMD20LV (aka Chester Champion 20VS, ST20LV, G0704, AMA20V) – full feature set, good work envelope, heavy/rigid for its weight, very nicely finished (always room for improvement of course) popular speed controller (read, easily diagnosed/repaired/replaced) easily broken down in to 3 liftable lumps and most of all….. A good price!

The comparably priced Sieg machines just didn't have the same size/strength and the RealBull type machines on offer at the time were smaller with tilting columns (hate them….) but well priced – basically like stripped out Weiss machines. I'm not sure if the Sieg machines have a better or worse quality finish, I don't think one has ever been sat next to another for direct 1vs1 comparison as they all require quite a few hours stripping cleaning finishing and adjusting before use.

Warco's WM16 gets my vote, and I'm sure there will be a special offer or 2 (at least!) on their Harrogate show stand

Hi,

I've recently bought a Chester Super Lux—I'm just a beginner but here are my initial impressions:

First, I found the folks at Chester a pleasure to deal with, always getting prompt responses to my emailed questions. The plastic chuck guard was broken on receipt and a replacement was sent immediately with no question. I opted for the x-axis power feed and this works well—I'm glad I went for this. The machine weighs about 300 kg and needed some careful thought to get it moved into position and up onto its supplied stand in a tight space in my workshop—it's about the biggest machine I could fit in. The motors (the main one and the one to raise and lower the head on its dovetail) are single phase and supplied with standard 13-amp domestic plugs.

There are, of course some negative points. The Super Lux has a 2-axis DRO (made by 'Sino' ) installed by Chester, and the x-axis scale is positioned along the back of the table. It works fine but the scale seems to rob the y-axis of about 40mm of movement compared with the catalogue specification. The quill scale and depth stop is rather crude and one of my early jobs will be to replace it with a caliper-style digital scale. The chuck guard has quite often got in the way when the head is low down and I need to think how to deal with that—up to now I have removed it when it is likely to hit something on the table. Finally the geared head is rather noisy—I'm told that this is characteristic of such drives (when compared with a belt-driven head).

Hope this helps.

Trevor

Besides considering nominal size and machining capability its important to look closely at actual work envelope, accessiblity, visibility and tool change space. Especially if you have been used to industrial size machines. In my view anything much smaller than a Bridgeport is of necessity going to be compromised to a significant degree in those areas as the space and volume requirements to avoid compromise are pretty much fixed and small machines just don't have the physical room.

Dovetail colum machines at least avoid the head location problem endemic to the round column breed where you have to fit tool change room and tool length variations in the quill travel but winding the head up and down can be a pain. I used to have a Chester supplied Lux style machine and rapidly fell out of love with the head lift crank. Power rise and fall is not a luxury on these. The fashionable square, boxy, head assemblies considerably reduce visibility. Its virtually impossible to get a decently downwards look at a milling cutter in operation, indeed with a short cutter nicely snugged up and a desirably short quill extension it can be darn near imossible to see anything at all however unlikely the angle. The base plan dimensions of the Chester LUX head are considerably larger than a Bridgeport J head.

Another unpleasant surprise for the unwary is the limited amount of table area actually covered by the cutter centre. On my LUX variant only about half the Y axis dimension and a little under 2/3 rds of the X dimension could be reached. Which rather took the shine off. Although the limited area covered can be a bit of a pain when actually machining its usually possible to manage the cuts unless the job, realistically, is oversize for the machine. It really bites when it comes to setting up because you are pretty much forced to work below, or at best half to onside, of the head with all the attendant visibility and bits in the way to deal with. No Bridgeport style cranking the table over so you can see and wave your hands around without getting cutter bites. With the smaller machines I'd seriously consider whether a miniature CCD / CMOS video camera would help see WTHIGO.

These and similar issues are best dealt with by physically viewing the machine and doing some serious handle twiddling whilst waving a tape measure around. Don't overlook the vice issue unless you plan to do all your jobs on the table or tooling plates. A vice large enough to hold jobs approaching machine capacity may well be too big to sensibly fit whilst one that fits easily may be too small to do your jobs. Same applies to rotary tables. Note that space needed for job clamping is pretty much fixed so smaller 4" and 6" tables are disporportionately smaller in useful area than larger ones. Another nasty surprise for me despite buying an 8" one, a 10" or 12" seems so mch larger in practice.

I found "grid of tapped holes" plates, mine were Thor Labs aluminium breadboards, much better than Tee slots for much work holding on the LUX style machine and the smaller BCA style machine which preceeded it.

Nick, I'd say off the top of my head…..

SX3

Lots of room to fit zero backlash ballnuts under the table and saddle! (this is a big bonus if you'd prefer not to modify the machine)
convenient front handle for Z axis movement – I'm 6ft so the high rear handle isn't an issue for me.
by far the best know Chinese brand and the only one to tout their own name on products.
Its got some nifty features, and its popular so plenty of others to learn from.

WMD20

ballnuts can be fitted but do sometimes require modification to the saddle if you want to fit a nice big beefy ones.
larger work envelope than the SX3
cheaper.
well finished and square (I believe the SX3 and other high end Sieg machines are also well finished)

You said you were a qualified toolmaker and CNC machinist.!

You should then know that a lathe would be best for that.

Nick

Clive,

The depth stop is just as you describe it and your modification will get serious consideration when I get 'a round tuit'. Thanks for the tip. I'm also wondering whether I should bite the bullet and move the x-axis DRO scale to the front.

Trevor

You will find its the overhanging power feed that's robbed X axis of its travel. Fitted Bridgeport style to mine extended lead screw and still lost over 3".

Scales easy to fit on the rear, that's why.

Chuck guard, I never powered mine up first thing to junk was the guard and switch.

Future CNC conversion of these has been done in fact can get from a US dealer who extensively mods them. Otherwise pretty useless at 1250rpm. Now the major disadvantage will be the heavy geared head that will need gib strips nipping up before any work undertaken constantly. If you don't like with any vertical dovetailed column the tramming will constantly alter.

These are cheap machines and don't last, admittedly mines as good as scrap but paid for itself even 8 years ago. Due to the bed length on these with narrow area the bed arcs! Bed should be a lot thicker for the length. Parts are available but real pricey ie the elevatation motors transfer box £244 as at 4 years ago, geez whole machine cost £930 ex demo when you could bargain with them.

If you were to CNC one of these extensive modding is a must, like beefing up the spindle bearings to take more than 1500 rpm and doing away with geared head.

Much better machine to convert but a bit small is the 626.

Must get me a new mill this year, something robust.

You will find the Weiss machines painted in various colours depending on who sells them in the UK, Warco, Chester, Toolco, SPG, etc all sell versions though spec and standard accesories can vary between brands

Hi Guys, new to the forum and looking to buy a small mill to compliment my Le Blond Regal 10 lathe. I had settled on either the Warco WM 14 or the Sieg SX2 Plus. Space is an issue and I would prefer morse taper, Imperial scales and single phase. Any thoughts?
