2x 2005 C7 Ballscrew 1450mm Length with Ballnuts + FK/FF mounts and motor coupler

[Shinobiwan]

Hi
I'm interested in the ballscrews and would appreciate some advice. I'm building a small machine approx 800mm x travel and 600 y travel. Gantry mass approx 20kg (+/- 2kg) with spindle. Would 2005's be up to the job?. i haven't got around to the calcs yet but for my machine I can just machine them to the right length.

Thanks in advance for any help / advice you may be able top offer

Cheers

I know this is academic since they're sold - sorry but I'd be tempted to go for 2010.

I'll be honest and say that I've swapped these out on my machine for 2010 as they're just too slow for cutting wood on the end of a nema 23. These small motors only run up to about 1000rpm with reasonable torque. Spinning at that speed the most you can reliably expect is about 5m/min traverse but little torque left for cutting. This is fine if your doing a lot of metal routing where your usually around 1m/min or less but for MDF like I do its just not fast enough where you need to be cutting 4-5m/min usually.

Depends what your cutting the most really! Judging by your gantry weight its not a lot so doubt it will be for metal. If your mostly cutting wood go for 2010 or even 2020 if your using the latest digital drives and suitable motors as these have very fine resolution using realtime microstepping adjust and signal input interpolation. If its metals then 2005 or 2010 would be fine.
