When evaluating a used Barber Colman 16-36, the real story is in the mechanical condition, lubrication system, alignment, and electrical integrity. On this machine, the work completed so far includes checking runout, measuring worm wheel backlash, installing a new lead nut, going through all lube lines, checking and...

If you are evaluating gear shapers for helical cuts, the short answer is this: not every gear shaper can do helical work, and the ones that can usually need either a dedicated mechanical helix setup or CNC-controlled axis synchronization. On older conventional machines, that often means a helical guide attachment, r...

When buyers ask about the advantages of differential and infeed on a mechanical machine, they are usually trying to understand one thing: what those features actually add in day-to-day production. On a mechanical gear hobbing machine, the answer is straightforward. A differential expands the range of gears the machi...

A retrofit and rebuild of a Gleason 14A straight bevel generator can be a practical way to extend the useful life of a proven gear cutting platform, improve reliability, and restore cut quality without starting from scratch on a replacement machine. For shops that still run straight bevel work, the real question is ...

A Barber Colman 6-10 rebuild is rarely about fixing a single bad component. On older multi-cycle gear hobbers, hydraulic, lubrication, electrical, safety, and feed issues often show up together. In this current client project, Piselli Enterprises is rebuilding a Barber Colman 6-10 Multi-Cycle 5231 and working throug...

A Barber Colman multicycle hobbing machine can offer major advantages for shops that need repeatable gear cutting, better cycle efficiency, and dependable production on a wide range of parts. For many manufacturers and gear-cutting operations, the real value is not just the Barber Colman name. It is the multicycle c...

If you are trying to understand the role of a gooseneck attachment on a Barber-Colman gear hobber, the short answer is this: it is typically a support and clearance attachment that helps the machine hold the hob setup more rigidly while reaching part features that a standard arrangement may not handle as cleanly. On...

When evaluating mechanical rebuild vs. full CNC retrofit for legacy Gleason gear generators, the right answer usually comes down to where the real constraint is. If the machine’s iron is fundamentally sound and your process is stable, a mechanical rebuild can restore usable life at a lower cost. If your biggest prob...

A Gleason machine rebuild can be the right move when a legacy gear generator still has good iron, proven workholding, and a place in your process, but needs accuracy, reliability, or control upgrades. For many shops running older Gleason 104, Gleason 116, Gleason 26, Gleason 503, Gleason Coniflex, or a legacy Gleaso...

A Gleason Mechanical Rebuild is intended to bring a worn gear machine back to stable, repeatable, near-original mechanical condition by correcting the parts and alignments that directly affect accuracy. For shops running bevel gear work, that usually means restoring slideways, spindles, bearings, drive components, l...
