Precision Machining Capabilities for BN
Complex geometry machining with easy machinability and rapid turnaround
Complex Geometry Machining
Standard carbide tooling enables intricate features, deep pockets, thin walls (down to 0.2 mm), and complex contours without specialized diamond tooling.
Rapid Prototyping Turnaround
Easy machinability allows fast iteration cycles. Prototype components can be delivered in 3-5 days for design validation and testing.
Tight Tolerance Machining
Despite softness, BN can be machined to ±0.02 mm tolerances for critical dimensions, enabling precision fixtures and insulators.
Thread Milling & Tapping
Internal and external threads can be directly machined into BN components, eliminating need for metal inserts in many applications.
Large-Format Fabrication
Machining of large BN plates and blocks (up to 400mm x 400mm) for vacuum furnace linings and thermal insulation systems.
Clean Room Compatible
BN produces minimal dust during machining and operation, suitable for semiconductor cleanroom environments with proper handling protocols.
