Banggood

Received in good order and fast. The couplings fit well. (I ordered 3; they come per piece.) There is however a disadvantage: the coupling elongate under tension, especially when milling deep. The elongation can be as much as 1 mm, depending on the mechanical resistance and doesn't always relax, depending on depth-of-cut and material.. This problem of course doesnot happen when engraving with a laser (no mechanical resistance). Thus: a good product, depending on the application. (I am thinking about placing thin rubber sheets in the grooves and drilling the center away. But, I have not tried that yet. Installing under pre-tension does help, but limits the side-movement.)

Die Wellenkupplung für Schrittmotoren ist eine bessere alternative als eine starre Verbindung. Der Schrittmotor wird geschont. The shaft coupling for stepping motors is a better alternative than a rigid connection. The stepping motor is spared.

Jó minőség bár némelyik belül egy kicsit sorjás, ami nem zavaró.
