Features and Patterns Possible
Bullen can machine a limitless number of different cuts and shapes.
View List
- Round Holes
- Rectangular Holes
- Odd-shaped holes
- Slots
- Blind Cuts
- Cavities
- OD and ID Work
Features ranging in size from 0.008″ up to several inches are possible in small workpieces, wafers, larger substrates, and material blanks.
Aspect ratios as high as 60-to-1 are possible, depending on the material type and feature size.
TOLERANCE FOR CNC MACHINING
We can CNC maching your part or use CNC machining to compliment Ultrasonic Machining to provide a complete solution to your component.

Advantages of CNC Machining and Grinding
Bullen’s machining 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.

Organizational culture can be challenging to get right. It’s not always universal, some workplaces have intentional cultures, and others might not even think about culture in their organization (even though it’s likely still in the background).
