الإطار الخارجي، أداة تدوير الكرات الصغيرة ونصف القطر (مكون)

The slots on this outer frame aligned perfectly with my lathe’s T-slots, making setup much smoother than I expected. Machining a 1/2-inch radius on a steel shaft came out clean and accurate on the first try.

Finally got this outer frame mounted on my metal lathe and the machining tolerances are impressive, everything locks up solid with no play at all. The cast iron construction feels substantial enough for repeated heavy use, and the ball turning radius action is smooth right out of the box.

The outer frame fits perfectly on my lathe and the threads are clean and precise. It took some careful setup, but now it cuts consistent ball shapes every time.
