Retrofitting a trapezoidal screw drive on a ball screw
The problem: Older dressing devices for grinding or regulating wheels are equipped with trapezoidal screw drives, which means the spindles allowing lateral movement have often worn out and no longer provide uniform support over the entire length. Ultimately, this means the spring-loaded spindle nut is no longer able to offset the play.
Solution: SFS replaces the trapezoidal spindle or replaces it with a ball screw.
The ball screw nut is preloaded for zero play and also ensures minimal frictional torque. During this conversion operation, SFS also often upgrades the old DC motor with a modern adjustable drive.
The new drive elements ensure uniform transfer of the carriage, which paves the way for a positive dressing result.
