Is the Syil / Sieg X3 suitable for climb milling?

[ServoGuy]

Ed;
You mentioned a g-code controllable spindle motor driver from Syil, and I have heard of other options, such as a different gear ratio or belt drive for a higher top end speed. Does anybody have a complete list of all the accessories that Syil now offers? I am about to place an order so I want to know what I can blow all my money on…

BTW: Do mind telling us what Syil nicked you for on the g-code controllable spindle motor driver?

He said that a lot of testing would need to be done, but that there is a good chance that the mill could handle that sort of power (with whatever upgrades). The major hurdle is that the electronics is not designed for it and redesigning the board is not an easy task because Sieg does not publish the specs. They have just designed a replacement board to control the speed via G-code (which I'm getting on mine), but the new board works with the same power levels. In order to handle a much larger motor they would need to redesign the board all over again and that is not feasible at this point. I told him that if he were able to come up with a 5 HP upgrade kit for the S/X3 there might be quite a few people interested in it... Perhaps we should all beg together .

Umm....
5HP is way over the top. It would require at least 220v. If it was DC, it would be very expensive, more than the cost of hte mill probably.
Or if it was AC, the VFD would cost about as much as the mill. Even the biggest bridgeport only has 3...
the DC controller would be quite costly too. The motor would weigh more than the head itself!

No need to use a motor this big

Gotta go to work, check McMaster #5990K62 (yes it is 220V).

I'll post my list of options as soon as finalize my order, but they all have been listed before -- bits and pieces here and there.

[phantomcow2]

THats great being one phase but, the VFD will be 3 phase in. Also, your 5HP will cost you ~$350.
You will never utilize the full 5HP....the mill is not rigid enough to make that motor really work.
Also, the motor will weigh more than the head of the mill itself .

Well until Syil or someone else comes up with an upgrade board supporting a larger current/voltage on the SX3 there is probably no upgrade option for me.

Just think it would be great to have a benchmill that would rip

A point on climb cutting. My experince has been that climb cutting is best done with a 3 flute 60 deg. helix push cut end mill. On my rf-45, I production cut a window in 1/2" thick aluminum with a 3/8 dia. end mill to .005 finished size in one pass with no problems. Feed rate is 9 ipm at 100% cutter dia. Check out Garr tool for the best end mills out there. They are expensive but you get what you pay for. Also zero backlash ball screws are really essential to prevent chatter.
