Typically AC servodrive peak torque is 3x the rated torque. Any servodrive (i.e. matched motor + amplifier) will withstand 100 ms duration of peak torque. It is rather the amplifier than the motor...

Rapid traverse rate is defined by the maximum RPM of the motor and not the peak torque. Peak torque of the servo motor defines the acceleration/deceleration rate of the driven slide. With the new...

Very interesting - we are a medium sized company and could be interested but we need description in English whit it does.

ref: post #5; "All REPUTABLE machine tool builders" use highest accuracy bearings only for the most critical applications. Also, they do not "apply heavy preload" but they apply preload which is...

You should consider using plain ball thrust bearings if you do not need high rapid travel - eg. a pair of 51104 and a radial ball bearing 6004/6104/6204. No machine tool manufacturer in the whole...

There is no rigid rule as to where the COG should be. Generally - the lower the better. You can always fill the base with sand - some professional machine tool makers do that. However, it will not...

The simplest and most economical solution is to use 52xxx series thrust bearing for the fixed end of the ballscrew. Mazak used them in their older M5 lathes. However, this requires careful tightening...

In fact this type of bearing arrangement was used by many machine tool manufacturers in the past. I have seen exactly this arrangement on an older Mazak M4. The reason why machine tool manufacturers...

This is all true with one exception - accuracy class of ground ballscrews! I worked for a ball screw manufacturer some years ago and this is my advice:
buy lower accuracy ground ballscrews because...
