Higher end Chinese controllers?

[Boyan Silyavski]

Did you guys read the connection manuals, not the general manuals? here is the one for the 990 controller. I have not read it all but i think its very well explained about the tool changers.

Spent the weekend doing ladder programming for my GSK980MDc. Not easy but doable. You cannot do it on screen unfortunately sk was going back and forth to the computer.

Really like my 980mdc, it does up to 5 axes and has built in logic for BT and Carousel type ATC's

Boyan, I never noticed there were different manuals. The GSK site stopped loading for me, however I got an Installation and Connection manual from the cncmakers website.
I've had a quick scan through it, and it seems to contain the necessary info, other than where to download the software :-/

Komatias, the SZGH/CNC1000 manual I mentioned earlier has a bit about the two types of tool changers at the end, however as I mentioned, it's not exactly clear as to what they're requirements are. Going by what I understand of the manual, it's aimed at certain changers which must be commonly fitted to machines.
Care to share some more info on what you're fitting one to?

They have also/ all the different manufacturers / additional boards, that they call" concentrator boards" so make sure you order the one with the relays on it. Its not expensive, i think, and will save you a lot of headaches.

M_C, yes there are generic ATC's that you can buy from the orient. They work on switches so the output of each switch is fed back to the PLC which inidicates e.g. the ATC is in place for a tool change or that the drawbar is unclamped, etc etc. I was looking at one with a geneva mechanism recently that is not too difficult to make.

So I really want to share what it is fitted to but I have to resist the temptation. Suffice to say, the GSK was standard on the machine as were the GSK servos. When I am good and ready with the machine it is on, rest assured you will know.

I understand. But tell me one thing. Did you find what is the real difference between 980 and 990 controls? I still can not find it reading the manual. Did you had any special preference not to buy the other company 1000 control versus the 980? As they are very similar. Or just price features commanded that decision?

Model numbering seems to be almost random. From what I've seen, I'm guessing 1000 series are basically 900 series but in a complete unit (900 series have separate display/control panels). The big problem with comparing models, is every spec sheet seems to be worded, laid out, and translated differently, so comparisons are hard to do.

I've had an email back from CNCMakers, and they've recommended the GSK218MC series, however as standard it only does a max of 3-axis simultaneously I.e it can only move 3 axis at any one time - I had to email them it clarify that.
I'm waiting to hear back.

I've also emailed Newkye to see what they recommend.

CNCMakers/GSK call the break out boards De-concentrators, and they have the option of basic ones that simply convert the 3 25-pin D connectors to screw terminals, as well as an output board with relays.

Chinese are on a vacation till end of the week. Its national holiday there.


They recommend the GSk218 as it is more expensive. They want too much money for it. Though i think it has to has some serious benefit for new modern machining centers.I have not looked deep into it. 980 and 990 are GSk but not the 1000, which is totally different company. The paneling is difference in letter V vertical, H horizontal and so on.

"Cnc makers" are very expensive resellers. Their only benefit is that they are a bit more responding, speaking english and have the web a bit better than typical chinese web. Nothing more. Their "wholesale" prices were ridiculous. And i said that to them.
