Lead screws have lower efficiency, ranging only from 2080%. Hence, they are not advisable for continuous power transmission. Lead screws must be replaced more frequently than ball screws. The wear of the lead screw threads is faster because a large amount of friction is generated. The wear can be compensated for through the use of a split nut.

Check for movement between cross slide and carriage with the pry bar. Movement in X could be loose bearing housing(s), loose ball nut housing on carriage, bad or loose thrust bearing, bad ball nut or worn ball screw. Check for movement between carriage and bed with pry bar. Movement in Z could be same reasons as for X.

The ballscrew mounts replace the leadscrew mounts on the Grizzly G0704 milling machine. They are designed to slip over the edge of the Ballscrew nut and bolt onto the flange with 1/420 screws. The previous version was easier to make but I felt the curves were cleaner and used less material.

This makes knowing and understanding the critical speed of the screw really important. As I implied above, SFU1204 screws are 4mm pitch you have to run them twice as fast just to get the same speeds as the standard 8mm screws 500rpm just to hit 2000mm/min "standard" rapids. That has a torque penalty.

Ball Screws. Ball screws utilise ball bearings to between the screw and nut, drastically reducing backlash. With up to 90% efficiency, ball screws are widely used in applications requiring high precision and repeatability which include but not limited to: robotics, CNC machines and linear actuators. Due to the high mechanical efficiency of ball ...

Lead. Lead is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified. For a single start thread, lead is equal to the pitch. For multiple start screws the lead is the pitch multiplied by the number of starts. Pitch is the distance between screw grooves and is commonly used with inch sized products.

Ball screws, unlike the simpler lead screws, operate by small, hard balls running through the channels of the screw shaft. These ball bearings are recirculated for continuous running and offer the main advantage of reducing friction and therefore maximising energy transfer efficiency. Due to this technology, ball screws are usually considerably ...

Although not as mechanically efficient as ball screws (a precision Acme threaded rod system operates at about 30% efficiency, while a ball screw system operates at about 90% or better), it is more economical and ideal for uses involving lower speeds and fewer cycles.
