Re-Balling
If you are
experiencing poor surface finishes, positioning accuracy or axis vibration do to the machines mechanics and have ruled out gibs and thrust bearings. Check the backlash between the ball nut & screw. If the backlash is anywhere from .0005 to .004, a 90% chance, with immediate attention, your ball nut/screw can be re-balled. At a fraction of the cost of a new one, it's well worth entertaining. Generally we can rebuild a unit within a two day period, depending upon stock components.
Re-Manufacture
If the screw and/or
ball nut show signs of scoring, pitting or spalling. The screw will need to be either reground or replaced. We have in many cases polished & re-balled the unit after blue printing (a temporary repair) thus keeping the machine operational. While a replacement screw is either being researched for purchase or being re-manufactured. This will keep valuable down time to a minimum.
Acme Screw to Ballscrew Retrofit
Depending o
n the space restraints between the machine components and the ball screws are designed with all the original specifications or higher as the Acme. Replacing the ever wearing Acme screw and bronze nut, substantially increases the machines accuracy and value.
