Lead. Lead is the linear distance along the axis of the screw that is covered by one complete rotation (3600) of the screw. It is an important specification of a ball screw which determines linear travel and speed and load capacity. As the lead of ball screws increases, the …

Permissible Ball Screw Speed. When the speed of a ball screw increases, the ball screw will approach its natural frequency, causing a resonance and the operation will become impossible. Where: n c = Critical speed [min-1] l b = Distance between supports [m] E: Elastic modulus [Pa] I = Second moment of inertia [m4] ρ = Density [kg/m3]

Ball screws; CNC Machine: This is the actual machine where the finished product made. I already mentioned the parts of the CNC machine above this heading. This is the housing of headstock, tailstock, foot switch, chuck, and tool turret.

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.

The mechanical part consists of replacing the lead screws in the mini-mill with ball screws and double nuts. The reason why you need a new mechanical system is that the lead screws in benchtop mills have backlash and are not really built for CNC operation. Ball screws have very little backlash and are an excellent choice for the drive of a CNC.
