This is the type of cable you need for the spindle http://www.csecables.com/acatalog/CY-Cable-4-Core.html 1mm or 1.5mm your choice. ..Clive

thank you Clive :)

Hi Clive, the spindle has got 4 entries whereas the VFD has got 3 entries. Do i need to use the same cable for both connections? Also, should a power supply for the spindle be included in the package that I have bought?

The VFD is the power supply/controller for the spindle. You need to connect power directly to the VFD terminals and it will control the power to the spindle.

See the first post in this thread for connection details.

Valeria, It sounds like you have very little experience with electronics so I seriously suggest you get someone with more experience to do this for you.

Your dealing with High voltage and very fiddly connectors and if got wrong it's very easy to damage the VFD and spindle beyond repair.

I've added a few bits to the OP, including some suggested amendments to the VFD settings. I will be posting more on that subject soon as there may be a way of getting more torque from the spindle at low speed.

I searched for these spindles and now I'm so confused...

solar.jean states on a few of his listings "FOUR BEARING"; first written only on the listing image for a spindle alone with "Japanese Imported Bearing" and second only in the listing title for the £252 spindle+VFD with "Germany Imported Bearing"

As I buy the ballscrews from linearmotionbearings2008 I saw that he also sells spindles which are far more expensive (£353). As I asked him if he can justify the higher price, he only made a "best special price" which is still £36 higher. The only important difference in the description is that he claim to professionally test them before shipping.

Now my dilemma comes from the fact that he already sold 54 of them at this very high price. And 54 are a lot!

I even read somewhere on the forums that the German bearings are actually made by a Chinese company named "German" and the Japanese ones are top brands but that specific model number is supplied only to China.

I'd buy from Chi. He's consistent and a decent chap. If things go wrong he usually fixes it. Solar Jean has been known to disappear off the face of the earth if you email with questions and especially if you want to claim on the warranty.

Both have only few negative and neutral feedback, and solar.jean mostly for $1 "Nail Art 3D Sticker" lol

Yes, I know Chai is way more consistent and professional. I read a lot of good things about him. Could this be the only reason for selling a lot of spindles at 40% higher price?

Could this be the only reason for selling a lot of spindles at 40% higher price?

The other reason is someone called JazzCNC keeps advising people to buy them from him. My opinion is just get the cheapest one since the differences between them, if you can even tell a difference, are bound to be negligible and I know plenty of people who've bought from other sellers and haven't reported problems. Mine, which was the cheapest I could find at the time, was from solar.jean and it turns out it has Chinese bearings, but they are marked as a match pair so that's pretty good. It also has 4 bearings not 3. He probably sells all sorts though, so don't expect that to mean you'll get one the same.

Jazz previously suggested upgrading the coolant fittings on these spindles for some push fit/lock type, I like this idea so here is a link to some on eBay:

High Pressure Metal Push-in Fittings for Air or Central Lubrication Systems Tube

You want the M8x1 fine thread option for the correct fit, dose/maybe the OP wants to add this info to the first post.
