CNC Machining

Precision CNC Machining — Up to 27" × 100"

Four-axis multitasking turning and milling, engine lathes and a boring mill — on material up to 27" x 100" and 2000 lbs, in research, prototype and production volumes.

What we machine

A repair is rarely just a coating. Worn material gets machined off before plating or spray goes on, threads and keyways get recut, and features get restored to the drawing. CNC machining is what makes the rest of the floor work.

We also machine new components outright — research, prototype and production volumes — for customers who are already sending us repair work and would rather keep it in one shop.

Fixturing is manufactured in house, which gives us greater control over the entire manufacturing process. BBC is a full service machine facility.

What sits alongside it

Machining is one step. These sit under the same roof, so a component does not ship between operations.

  • Industrial hard chrome plating
  • Thermal flame spray, plasma flame spray and twin wire arc spray
  • Precision grinding and honing
  • Welding — MIG, TIG and arc
  • Cast Babbitt
  • Dynamic balancing
  • Shot peen

Verified before it ships

Machining is checked against customer prints and specifications in the same building.

  • Complete inspection department
  • Magnetic particle inspection
  • Liquid penetrant inspection
