Barber-Colman Rebuild Specialists

C&B Machinery has redesigned Barber-Colman Gear Hobbing Machines to simplify and utilize standard off-the-shelf parts for reliability and maintainability. Combining our end customer’s different machine models and designs into one common design. We use reverse engineering of key components to allow us the opportunity to provide machine drawings to our end customers. A completely new spindle and top slide design that have the capability to function across all models.

Key Upgrades:

  • New Upgraded Hob Spindle Design & Casting
  • Upgraded Work Chuck Spindle from Brass Bushings to Bearings
  • Machine Fitted with X/Y Digital Scales and Readout
  • Integrated Automatic Cycle Shutoff with Dwell Timer
  • Re-Scraped All Machine Ways
  • Upgraded Vertical Feed Screw Assembly
  • Several Upgrades from Bushings to Bearings to Increase Machine Longevity
  • New Electrical & Control System

C&B looked for a way to provide a solution to streamline the setup process and provide aids to eliminate operator guesswork. We integrated X/Y digital scales with readouts. The scales replace the old limit switch that was used for the table in-feed, now providing an accurate and consistent gear depth that greatly improved the quality and reduced scrap rates.
