Characteristics of ball screws • High mechanical efficiency In ball screws, about 90% or more of the force used to rotate the screw shaft can be converted to the force to move the ball nut. Since friction loss is extremely low, the amount of force used to rotate the screw shaft is as low as one third of that needed for the acme thread lead screw.
Introduction to Milling Tools and Their Application
Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

When should you choose linear motors vs ball screws
While ball screws typically use a rotary encoder mounted to the motor for positioning feedback, linear motors use a magnetic or optical linear scale for position feedback. The linear scale measures position at the load, which gives a more accurate reading of the actual position. For very high-precision applications, this more accurate position ...
