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.

3. Carrier is set up in our special carrier grinder and adjusted so that when ground, the stem centrality is optimized to all spindle bores
4. Stem is finished ground and polished
5. Carrier O.D. bearing diameters are indicated and polished
6. If carrier O.D. bearing diameters are not concentric to new finished stem, they are minimally ground to match stem
7. Carrier spindle bores checked for spun bearings and indicated for alignment
8. Carrier spindle bores if out of acceptable limit shall be bored, bushed, and re-bored at additional cost
9. Front and rear bronze retainers inspected and replaced as necessary
10. New front and rear oil flingers installed
11. The spindle gears are inspected and replaced if necessary
12. New class #3 spindle bearings installed
13. Rebuilt work spindles installed

Main Tool Slide / End Slide Rebuilding and Repair:

1. All main tool slide key ways and surfaces irregularities repaired as necessary
2. The main tool slide will be ground flat on all faces
3. Main tool slide bushing replaced and bored to fit stem
4. Flat and taper gibs to be replaced
5. Front and rear stem seals to be replaced
6. Grind and resurface existing guide block
7. Optional: All main tool slide holders to be bored and bushed for re-boring on machine at additional cost
