Ball Screw Vs Rack And Pinion Cnc
For this reason laguna has chosen the ball screw for axes under 4 rack and pinion in laguna s larger cnc routers the rack and pinion method is used to handle the x and y axes.
Ball screw vs rack and pinion cnc. Helical rack and pinion. Rack n pinion rack n pinion explained most machines in this price category use strait rack n pinion to drive the axes. Rack and pinion vs ball screw a very controversial topic there is plenty of information not always true out there about both ball screw and rack and pinion drive systems. It is a design where the teeth of a steel pinion gear are pushed into the teeth of a steel rack.
It is a design where the teeth of a steel pinion gear are pushed into the teeth of a steel rack. The ball screws on our cnc router tables consist of a sealed bearing with many re circulating ball bearings evenly spaced and constantly lubricated as it moves through a channel design. Because both axes are at least 4 on our larger cnc routers the rack and pinion system was the ideal choice. Both are used across many industries and transfer rotational motion into linear motion systems to move and position machines.
The channel is cleared by wipers ahead of time to prevent any debris or dust from penetrating the inner bearing.
