Precision CNC Turned Flanges

Detailed Description

Our precision CNC turned flanges are manufactured for mechanical connection, mounting, positioning and sealing applications. CNC turning is used to control the flange outer diameter, center bore, mounting face, shoulders and hub features, while drilling or milling creates bolt circles and other installation features.

Flat flanges, stepped flanges, hubbed flanges and custom mounting flanges can be manufactured according to customer drawings. Surface finish and face geometry can also be controlled where the flange interfaces with bearings, seals, housings or mating components

Available Surface Finishes

• Zinc Plating: Provides economical corrosion protection for carbon steel flanges.
• Black Oxide: Protective finish commonly used for steel mechanical components.
• Anodizing: Suitable for lightweight aluminum flanges.
• Passivation: Improves corrosion resistance of stainless steel surfaces.

Structural & Functional Breakdown

• Central Bore Structure: Provides shaft, pipe or component positioning through the flange center.
• Bolt-circle Structure: Precisely positioned mounting holes support repeatable assembly.
• Stepped Face Structure: Provides locating surfaces between mating components.
• Hubbed Flange Structure: Extended central section adds support around the bore or shaft interface.

Key Features

• Precision Face Turning: Produces controlled flange thickness and mating surfaces.
• Concentric Bore Machining: Maintains alignment between the bore and outer turned features.
• Bolt-hole Integration: CNC drilling or milling produces customized mounting patterns.
• Custom Face Geometry: Recesses, shoulders, grooves and sealing surfaces can be integrated according to drawings.

Applications

• Pumps & Motors
• Gearboxes & Drive Systems
• Industrial Pipe Connections
• Machine Housings
• Automation Equipment
