The Bullen Advantage
Bullen’s CNC machining and grinding process has many advantages over traditional machining.
Precise
Top-Quality
Consistent manufacture of complex parts
The process integrates well with semiconductor ceramics and MEMS Machined features, and it can be aligned to previously patterned, machined, or etched substrates.
Traditional Machining Limits Shouldn’t Hold You Back
ABOUT CNC MACHINING AND GRINDING
WHAT IS CNC MACHINING?
CNC machining is a process in which computer software controls the movement of cutting tools allowing for highly accurate, precise, and consistent manufacture of complex parts.
