Will this K2 CNC do the job? - cue making

K2

The machine has several feature that I like. Linear rails (square), ballscrews, and servo's.
I don't like that all the rails are uncovered. I don't know much about their controller, so I would ask lots of questions about it. Especially about tech support. You want to stay away
from proprietary designs if you can. I have a Techno which is similar in design. Nice machine, but don't even think about messing with the controller. It's a closely held secret and techno won't really give you much info unless they are selling you something else.
I wanted to hook up a vfd and their answer was a question, did we sell you the vfd. If not, we can't help you hook it up.
 
Thank you cutter. very much appreciated.

to JoeyInCali, I looked into Techno, but they told me they stopped making the smaller CNCs. The smallest they offered me was a 4'x8' which was too big and too expensive.

I'm not from Romania.

I answered yo and said that i wouldnt spend that kind of money on a machine like that

and told you id sell you mine which already has all software and a 4th axis that will index and spin for tapering.

along with that i would include a ton of tapering and inlay programs so the machine is litterally turn key plug it in and GO!

all for only 1000 more than the machine you listed.

i was just trying to help you out, good luck
 
I would prefer to buy from a company. I'm not prepared to drop thousands of dollars on a random persons machine. Especially if I'm unfamiliar with the equipment. Thanks though.

From afar....for sure.
The linear rails are about the nicest thing on the machine and i'm not positive but i believe they are knock offs with no brand name.

The one i have seen had 5/8" rolled isel ballscrews with a very fine pitch and from feeling the nut, i would say that the accuracy grade was at the extreme lowend of the chart.

Servos, No..... Servo Drives yes. Actually cheap DC motors with encoders strapped to the back of them. The only logical explanation i can think of for the machine even coming with servos is for the feedback because without it steppers would likely stay out of position due to binding/racking. of the 1/4" plates that main components are bolted too.


The controller = little metal box with g320's inside. No i/o option at all. Limit switches hooked directly into the servo motors power wires. E-stop is controlled by mach via a USB cable:eek:

Then theres the rotary! Another engineering marvel, before i took it apart and re-machined it, had about 2 degrees backlash. Think that would show up in cue?

I could go on but it will just remind me of the work ahead, which i really dont mind as it comes with great knowledge.

If you go to the site you see how they tout USA made, i'm guessing at that point they hope that only idiots will be purchasing machines.

Ultimately, as i've said before...these turn key machines are punishment to the lazy who dont want to do the research. They then find out they have an $8k piece of garbage that needs another few thousand to get it legit.

YES! this is good. This is the stuff I want to hear. However, you're so sarcastic it's tough to figure out what you're saying. Not that tough though. Above quote, what's all this about? By lowend of the chart in accuracy, i'm guessing that's not low like .0001" accuracy, but just low accuracy.

But to sum up what you are saying. You basically just bashed K2 CNC pretty good. It's really that bad? If not K2, then what?

I really don't want to build a machine. It's something I imagine I'll learn a lot about eventually, but I'd rather learn to use the machine.

No, actually it would be high on the scale like C7 at best. .0001 shouldnt be used in the same conversation as this machine.

Theres no need for me to really bash it....just find one and make an assesment after your educated.

If i was going to buy a machine ready to run and i was on a budget then theres only two considerations imo. Take into consideration that this is considering your serious about building cues and you want to buy something that will last your career. Your not going to spend 5-10k and have no worries like you would with the below machines. There is the off chance that you can find someone who will build you one with quality in mind other than capitalizing on your ignorance.

I'm not sure I follow. What are the two considerations for someone on a budget?

Lets call the budget $7k

1) you can be lazy and blast that $7k at a bullshit machine that you will regret

2) you can study and build something as accurate as a $50k machine for $7k or less.
 
I have the Alignrite CNC and have never had a problem. It is well made on top of a Jet wood lathe and I would reccommend to anyone wanting to get into CNC as they have customer support for the first year. They also supply with generic tapering programs for shafts and butts to help get you started.

www.alignritetool.com and look under poolcue system. Give Matt a call.
 
It's just me,but I think the K2 will certainly do the job,in the right hands.

I'm telling you as someone that has been thru a machine shop course,and graduated.

If you can't simply DOMINATE a manual lathe and mill,any CNC is going to be a hell of a steep learning curve.

You have to KNOW how to run a lathe or mill manually before you can know what to tell a CNC to do.

I'm not trying to discourage you at all. If you have the bankroll to buy it,go for it. Believe me,if the cash allowed it I'd already have one. Tommy D.

Wouldn't you need a good knee mill to build that cnc yourself , Jake ?
Even if you had 3 great THK actuators and extrusions ?

Not to digress to far, but .0001 for 7k. Maybe in a straight line, but circular
under load and at a reasonable speed. That I'd have to see the reciepts to
believe. Oh yeah, testing with a indicator doesn't count, let's talk
laser and reninshaw ball. .0001 is way more than you need to
build cues,
 
I'd bet money there isn't a cnc mill in the world, at any price, that will give you .0001" part accuracy or part precision :)
