CNC Turning
Outer diameters, inner bores, spigots, sealing grooves and end faces.
Custom Parts
CNC Machining Precision Flange
TyCNCparts covers outer diameters φ20–φ500 mm. We hold bolt-hole positional tolerance to ±0.01 mm and sealing surface flatness down to 0.005 mm for vacuum, connection and spindle flanges.
Capability
Our Flange Machining Capabilities
TyCNCparts mainly uses CNC machining centers and turn-milling for precision flanges. For flanges requiring high flatness on sealing surfaces and datum end faces, such as vacuum and sealing flanges, we also perform surface grinding to support sealing performance.

Machining Processes
TyCNCparts support manufacturing high-performance flanges with good critical features like sealing faces, holes, special grooves, pilot register through the following machining processes.
CNC Milling
Profiles, bolt holes, countersunk holes, through holes, threaded holes and dowel pin holes.
Turn-Milling
Single setup for OD/ID, end faces and hole features; preferred for high-precision flanges.
Surface Grinding
For high-flatness sealing surfaces and datum end faces.
Boring
Precision finishing of inner bores.
Tapping
Threaded-hole machining.
