Thermal drift at tool centre point (TCP) is caused mainly due to positional errors in feed drive system of machine tool. The important sources of these errors are frictional heat generated at contact areas such as ball screwnut, bearing races and balls. In addition to this, heat losses of motor also contribute resulting in thermoelastic deformation in feed drive system. The objective of the ...

The first photo shows the sanding drum in its holder. It was not until I put it in there that I realized that I needed a keyway (the red circle on the blue pulley) This made for a challenge, since the sanding drum is 25 lbs + and its three feet long. The placement of the slot for the keyway is critical as it needs to be dead in the center of the shaft since that is the way that the pulleys are ...

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.
