A ballscrew is used in place of the Acme-thread leadscrew because it is more accurate, has better wear characteristics, has lower inertia and friction, and will perform more smoothly under far higher cutting loads and accelerations than its Acme counterpart.
The decision didn't come easy for Landis, which has built its success on proven hydrostatic leadscrew technology.
The TLS-6000 Series now has seven models, all featuring automatic alignment, bar code support, a positive-pressure filtered air system, ultra-reliable leadscrew mechanisms, and many other features that have made Qualstar libraries the choice of IT professionals, worldwide.
In addition to learning how to properly use accurate measuring instruments, machinists have to understand and deal with leadscrew backlash (reversal) error, non-linear leadscrew error, machine orthogonality, and related conditions whose roles become more significant as accuracies become more stringent.
The cylinder's leadscrew is typically driven in-line, in-line though a gearbox or offset via belt-drive, with stepper, servo or DC motors.
At EMO 97, Hyprostatik Schonfeld introduced a hydrostatic leadscrew with high stiffness for heavy loads.
The HBN series eliminates backlash between the leadscrew and nut interface.
The holder provides the necessary rigidity required by the higher rotational speeds and has a unique 1mm length compensation feature, allowing for spindle overruns and leadscrew backlashes.
Simplified direct drives through the leadscrew help to reach these feedrates, as well as an entirely new concept called an electric linear drive, which completely eliminates the leadscrew and will allow 60 meters/min in both the feed and rapid traverse modes.
patterns of roughness) often results from hardness variations in material, unbalanced grinding wheel, or errors in the machine's leadscrew.
Wedin International supplies a complete line of new and replacement components for machine tools, including precision-ground, semi-precision, and rolled thread ball, Acme, leadscrew, and nut assemblies up to 19" diameter, and offers 24-hour ballscrew repair service.
Push, pull, and retard problems can occur on both non-leadscrew and leadscrew machines.
