I have the sh-cnc 6090 (600mm x 900mm). For the size and price, you can not beat it.
The only problem I have had was to replace x and y ball screws. The factory forgot to put grease fittings in the ball nuts. Needless to say after a few hours of operation, the ball bearings wore out. There was absolutely no problems with getting replacements. So, when your machine arrives, check the ball nuts for fittings and give it an extra shot of grease to be safe.
Overall I am very satisfied with the machine.

Lee, You wrote that you could not find any grease nipples on your machine. Could you have the same problem as bclark?
You need to grease your nuts!
Also you mentioned using crc to clean things up - did you force some grease into the bearings on the ends of the machine?
Who are the New Zealand agents that deal in these machines?
Have a great New Years Eve. Don`t get drunk too early or you will miss all the fun!

I don't have metal filings on my rails leef, so sounds like a good idea to get in touch with Taney about it.
The issue of grease nipples seems to be up in the air, Scott doesn't grease his at all and just uses slide way oil, whereas I think Jimmy greases his linear rails.
As for noise, we've made some audio files of what my machine sounds like when moving in each axes at high speed, the microphone was about 2 metres from the machine and kept in the same spot for each recording. You'll probably need to turn up the volume a fair bit for it. Let me know if yours sounds any different.
I give my nipples a good generous pump whenever I notice less grease present where the guides run.
I'm still using the machine oil donated by a friend in the lubrication distribution business. He told me it is designed for machine guns and being light and designed to stick on components seems to do the trick well (I really like the way that stray dust doesn't seem to build up it).
Your machine sounds healthy Tom. I'm getting used to the sound of mine now that I have increased the process speed. When delivered it was set at 9m/min cut and 3m/min traversing between stations. I am now cutting at 12m /minute and traversing at 30M/min as I get used to things and really liking how it runs (my kids reckon he sounds like a robot).
Hi Jimmy, is that the grease nipple you are greasing in that red painted area of the image I've attached? And if so does a standard grease gun fit it? It's interesting how different people have different ideas about lubrication.. Scott has said he's not a fan of grease on this small machine because it's a magnet for dust and it's too thick for the rails.
You've also confused me when talking about increased process and traversing speeds, aren't the maximums 4 m and 6 m per minute respectively for the SHG0609?? Or are you talking about your larger machine? 30 m per minute?!
Rocket,
Sorry it took so long to get back to you, a little under the weather. To answer your question, use standard lithium grease made for grease guns. I sqweeze some in every 15 - 20 hours of run time. Router bits are generally a personal choice, I tend to use a fairily high quality bit making cabinets in hardwood veneer. The more you can keep dust at a minimum, the better off you will be. Check with the company and see if they have a dust shoe for the spindle.
Hope this helps.
Brian
P.S. The ATC is definately a good choice.
I'd get the ATC, if you still can. It's an automatic tool changer. There is no learning curve, it's automatic. Seriously, a simple setting in your CAM program is usually all that's required, and tool changes will be done automatically with no intervention required. Even if you write g-code by hand, tool changes are extremely simple.
If you make parts that require more than one tool, it will pay for itself very quickly.

i also am on the verge of a purchase and have narrowed it down to
one of five, i can really appreciate the amount of study involved and
how many varibles there are before a purchase. i do hope you will post your experience here for us. i have looked at shop bot and visited their factory,
had extensive conversations with dyna cnc, ezcnc.com,shop sabre and
techno. i have seen all thier dvds, looked at thier equipment they are all good machines and all within the same price range.
i have a fairly large custom cabinet shop and now see that i should have done this (purchase cnc) a long time ago. at present we are working out lease
arrangements as the tax man cometh!
whats really funny is i bought a carvewright and learned cnc in about 30 minutes after 20 years of fear over what cnc could do for me

Our first machine was almost $150K, and we spent about a year looking at different machines and doing research. I also spent that year trying different software packages, and learning how the software process worked before we got the machine. That allowed us to get up and running almost immediately.

Yes, and we also bought a $100K saw and $15K in software at the same time.
Vectric's software was the first of it's kind as far as I know. There were $500 packages that did V-carving only, but not that did everything V-carve does.
Software is very dependent on what kind of work you're doing. It's hard to go wrong with V-Carve pro, and it's very easy to use. But if you don't need the V-carving, you can probably do all you need with a $100 CAD program and something like SheetCAM.
We use specialized cabinet software which automatically generates all the code for our cabinet parts. But for all our custom work, I just do quick 2D cad drawings.

This thread is about our first cnc router purchase for our small family business.
We are located in Australia and do not have the availability of many different brands that our friends in the USA can select from.
At this moment we have absolutely no experience in cnc. Our machine is due to arrive in Australia in mid December 2007 and it is our intention to provide an ongoing summary of our attempts to learn about the machine and how to operate it.
The cnc router that we have purchased is from a company located in China called sh-cnc The brand is Excitech.
The specifications are - SHM1530A Router Machine
Table size 5ft x 10ft ( 1500 x 3000 )
Spindle 3.5KW ( 4.7 HP ) HSD
Stepper Motors
Becker Vacuum Pump
If you read through this thread you will see that i had deleted a lot of my early posts. This was because a member had ( in my opinion ) tried to derail the thread by posting negative stories about our supplier. I figured that he was from the anti import crowd. His story in my opinion is preposterous, but as it has been pointed out to me that everybody is entitled to their own opinion, i am attempting to restore as many details as possible. Make up your own mind.

Yeah I know china is kinda the Hoes of the world, they run everyone out of business from outsourcing but god bless them they make stuff good but for cheap. I get the 1/64 scale Diecast racecars from ADC made in china and wrap them to look like local race legends. the detail is amazing and there is even plug wires a working stering wheel, soft fuel line and seat belts and even through a us distributor the are $32 ea. how can they cast all those parts and put it together ship over seas and the US dist makes money and so do I. That is how it goes I guess. With out china there would be a lot of things we use every day that would not be so affordable. I will check out that site though I am sold on shop sabre. thanks.
davaro, back in November 2007 we paid 20k ( USD ) all up delivered. Not what i would call expensive compared to most cnc router machines.
More than happy with the quality. The Excitech continues to perform extremely well. One thing to be careful about is to LUBRICATE the machine weekly or you can have problems.
We are very glad that we bought it!
Cocobolo, I have no idea what caused your problem, but hope you do not discard your work of art. Surely you can use some filler or slightly alter the design to integrate it.
Rocket.
Hi Rocket,
Yes, I will probably just remove the whole flower (with the router, making it flat). Then I will glue a piece of mahogany onto the flat surface (taking care to match the woodgrain of course). And then route the flower again. If I do this carefully, I think it will be almost invisible.
By the way, I had many problems with the rough edges of the artwork. I did not understand what caused that. It turned out yesterday that it has to do with the resolution in Artcam : I had it on 1000x1000. The edges get jagged when I do that. If I first put the resolution to 4000x4000 and then import my STL file, it looks very very smooth. So I am thinking of making the cross again with the high resolution. But first I will try to finish this one (after I solved the z-axis problem).
This forum is fantastic by the way ! :cheers:
I went to that factorynew.com site but I guess that the Bloody greety american distributor figures that the same machine you have that you paid $16,000 is worth $29,000 in the usa.
Unless I am mistaken I went there and found the 5x10 with 3.5 spindle a t-slot table but it is no where near $16,000. Everything doubles when it crosses to the western hemisphere because Aparently us americans have twice as much money. You gota love a county that is allowing Illegal imagrants to draw social security though they never worked a day here.
