Spindle Carrier Rebuilding & Toolslide Repair

The spindle carrier is the most substantial component in providing accuracy and holding tight tolerances with your multispindle screw machine, which is why extensive care and attention to detail is given to each and every one of our carrier rebuilds.  The entire rebuilding process is done in-house, including the grinding, which is done on our custom built Landis O.D. grinder set up exclusively for grinding spindle carriers and tool slide stems.  We have the capabilities required to re-bore your headstock (carrier housing) if needed as well.  All with quick turn around time, minimizing lost hours on your Acme.

Our spindle carrier rebuilding and repair department will totally disassemble your carrier, can repair spindle bores, grind and polish the tool slide stem, bush and bore the tool slide, install new spindle bearings, rebuild or replace the spindles, and anything else that may be required in order to bring the tolerances back within acceptable limits of your spindle carrier.  We will reassemble and replace all necessary components such as spindle gears, bearings, oil flingers and seals, making your rebuilt spindle carrier, stem and tool slide new again within OEM specifications.
