Comments on Keling KL-6090?

[jbarber]

I'm considering the KL-6090 and I have a few questions.

(1) Does anyone have any experience with these machines, or have any comments?

(2) My usage requires high accuracy/repeatability at normal feed rates. For example, making a 1/4" cut in 3/4" MDF with a 1/4" two-flute tool at 100 IPM, what would be the maximum flex error? Other examples using different numbers would be ok.

(3) The packing list shows two collets. What size(s), US or metric? As with parts are they easily obtained in the US?

(4) Availability of parts. US or metric, sources?
For example, bearings, spindle components, VFD, BOB. Can parts be sourced and purchased easily?

As you can tell, I'm nervous about purchasing a Chinese or other metric machine.

Thanks!

Jim,

John at Keling has been very good with customer service.

I am guessing the machine is actually built by Excitech.

Here is a very long ongoing thread that you may want to read.

Excitech Cnc Router Purchase

The machines are extremely popular in Australia.

Repairing the machine wont be very difficult.

Anyone that is well versed with these types of machines should be able to handle any crisis.

Thanks for the link to the thread, Jeff.

I'll email Keling directly over the weekend with specifics and keep an eye out here as well.

Jim,

What do you plan on making with the router?

Primarily one-off engineering prototypes in MDF, acrylic and aluminum. some recent examples include several different speaker cabinets, an underwater camera housing and chassis/small parts for a remote antenna coupler for a transmitter. If it involves audio, RF or (to a lesser extent) optics I seem to end up with it.

I currently have a machine from a small US manufacturer that requires slowing down to roughly 5 IPM in MDF and acrylic to get kind of accuracy/repeatability I'm looking for. To get right to tacks, I'd like to have something like .002" repeatability at 100 IPM, but am willing to compromise a bit from there. The 5 IPM I'm getting right now is too slow for even prototypes. My clients love the results and being able to have the design and prototypes done in one step, (from their perspective) so there's no going back now even if I wanted to.

So... in a nutshell, I use the CNC router more like a large mill. I've done exactly one sign in my life, and that was under orders from my wife. :-)

Thanks,

Very nice! Thanks for linking those up.

I did notice that the Excitech SHG0609 shown in the videos resembles the Keling KL-6090 , although the SHG0609 that turns up most often with a web search doesn't resemble either of them.

I'll have to see what Keling says about ultimate repeatability, but assuming the model they sell chews up material like the one in the video without flexing much it would appear to be a substantial improvement over what I have now.

Well over 10 hours today babysitting a 12" x 12" x 3/4" cast acrylic parts nest at 5 IPM. It just finished at almost 2AM PDT.

Thanks again, Jeff. I'll look into it further.
