Title: My new CNC mill. JEH Guitars
Post by: Jens H on March 30, 2009, 09:08:47 AM: I have used and uses a step-four mill for manufacturing Guitars ( www.jens-h.dk (http://www.jens-h.dk))

It was beginning to be to little and slow for my needs, and there was also some issues in stability.
I desided to build my own, designed to my needs.
Data:
X=1050mm;Y=450mm;z=150mm (can handle the outline of a guitar.)
Ball guides and ball spindels.
Feed > 5000 mm/min.
Servo motors for loops feadback (I have destroyed som guitarbodys because of losing steps) nema23 DCservo.

Here is some pictures.

I have run the machine with the motors, and the axis work well up to 7000mm/min. They are very strong. I have some problems with the limits switch, but the disapear when I change cable to screened cable.
Know I only have to do the final alignments, and get to know the software.

The machine looks beautiful, thanks for sharing the build pics.

Browsed your website as well, looks like some nice stuff you're producing, just wish I could read the language, lol!

Thanks,
Dave

Yes my costumers are only Danish at the time, and they are happy to follow there projects in danish :) .

The mill is a KRESS 1050. I have good experience with the KRESS 800, so I desided to go for this one. (1050 watt)

Here is some pictures taking yesterday. Here is the KRESS mounted.

The Pink color is only protection cover.

Sounds like you're not entirely happy with the color pink? I'm still stuck in the 80's (guitarwise!) and I love the guitars from that era as you can see in my picture.....lol!

Thanks for sharing, it looks great- 8)
Dave

By the way, I'm thinking I should start a guitar thread since we have a few fans here ;D

Post by: ger21 on April 01, 2009, 11:04:26 AM: Dave, I sold a similar guitar to the one on the left a few years ago. Had an awesome orange/black crackle finish. I've got an old homebuilt pink guitar in the garage, waiting to be cannibalized one day when i find time to build a new one.

Post by: budman68 on April 28, 2009, 11:17:14 AM: Nice work, Jens, do you have any of your own body shapes at this point?

Dave
Title: Re: My new CNC mill. JEH Guitars
Post by: Dan13 on April 28, 2009, 12:24:50 PM: Excellent job Jens. But as I commented on YouTube, what about the ball screws? They are exposed to the dust?

Daniel
Title: Re: My new CNC mill. JEH Guitars
Post by: Jens H on April 29, 2009, 03:33:44 AM: Thanks everybody.
I do my own body shapes, but costumers will alwas have something they know.
The G-code is made from Rhinocam.
Yes, the spindels are exposed to dust. But there is dust everywere in the workshop, and I haven'nt found a good way to protect them. Because if I cover them only 90% the dust will still be a issue, but the cleaning will be more time consuming, and then I will not clean them offen.

Post by: Dan13 on April 29, 2009, 03:47:42 PM: Jens,

I see your point about the ball screws. At least I hope you have mounted wipers on them....?

Post by: Jens H on April 30, 2009, 04:20:36 AM: Yes, there are seelings on the nuts, and grease cups, so they can be lubricated from the inside, and press dirt out.
