Why 5-Axis for Kovar Components
Fewer setups, better geometry, and improved surface health – all tailored to Kovar's unique machining behavior.
Fewer Setups, Better Datum Integrity
Maintain relationships between sealing flats, weld lands, and alignment features in a single workholding strategy.
Access to Complex Geometry
Machine deep pockets, micro-channels, and oblique features without compromising thin walls or edge quality.
Improved Surface Health
Optimize tool engagement to manage heat input and work hardening that can otherwise distort thin sections or degrade seal surfaces.
Consistent Results in Low Volumes
5-axis programming and fixturing tailored to one-off and small batch runs, with repeatability for production orders.
Parts We Machine in Kovar (ASTM F15 / Fe‑Ni‑Co)
Hermetic housings, lids, rings, frames, and complex precision components for high-reliability applications.
If your drawing calls for high‑reliability sealing, controlled burrs, thin walls, or small features, our process is tuned for it.
Core Capabilities
From 5-axis simultaneous milling to CNC turning with hybrid features.
5-Axis CNC Machining
Simultaneous and 3+2 strategies for complex geometries.
CNC Turning + Milling
Hybrid features for parts requiring both rotational and prismatic operations.
Prototype & Low-Volume Production
Agile runs from first article to repeat batches.
Deburring & Finishing
Strategies for critical edges and seal interfaces.
Inspection Support
Dimensional documentation and reports upon request.
Material Certification & Traceability
Lot traceability for Kovar/ASTM F15/Fe‑Ni‑Co alloys.
How We Control the Variables that Matter in Kovar
Heat, thin walls, burrs, and sealing features – managed through proven process control.
Heat Management
Toolpaths, feeds/speeds, and coolant usage designed to limit heat input and mitigate work hardening.
Thin-Wall Stability
Purpose-built fixturing, step-downs, and balanced stock removal to preserve geometry and cosmetics.
Burr Suppression
Sequenced cuts and targeted deburring to protect sealing edges, knife-edge features, and fine grooves.
Sealing Features
Datum schemes and in-process checks focused on flatness, parallelism, true position, and surface finish per print.
Industries We Serve
From hermetic electronic packaging to aerospace and medical devices.
Design-for-Manufacturability (DFM) for Kovar 5-Axis
Send us your 2D drawing and 3D model early – we’ll help protect function and reduce risk.
- Favor stable, uniform wall sections where possible; avoid abrupt transitions that concentrate heat or stress.
- Use generous internal radii and avoid sharp internal corners that drive tool deflection and burr formation.
- Define sealing surfaces clearly (flatness, parallelism, surface finish, and datums) and call out any no-burr or edge-condition requirements.
- Specify edge breaks or controlled chamfers on non-sealing edges to minimize incidental burrs during handling.
- Consider access for deburring and inspection on small, deep, or intersecting features.
- When threads are required, specify class, depth, and any pre-plate/finish allowances; provide thread relief where applicable.
- Apply GD&T to communicate functional relationships; align datums with assembly and sealing needs.
- Share application details (e.g., weld vs. solder seal, glass-to-metal interface) to guide process decisions.
We’ll return practical feedback on risk areas, suggested adjustments, and inspection strategy before chips are cut.
