Flanges and fittings: end face, bore and outside diameter turning, bolt-circle drilling on a second machine and tray or magazine feeding in batches.
Flange and fitting machining and automation
Flange and fitting (Flange, Flange disc): A disc, or a disc-and-sleeve combination, where the end face and the bore are the main datums ... The page runs from what the part is and where it is used, through the machining process and machine selection, to automatic loading, feeding, inspection and the business lines that cover it.
What it is
Flange and fitting (Flange, Flange disc) belongs to the general machining group. A disc, or a disc-and-sleeve combination, where the end face and the bore are the main datums, usually with a bolt circle.
Where these parts come from
The industries this type of workpiece appears in; each industry page sets out the machining and automation entry points for its parts.
How the part is machined
The features and operations this structure usually calls for. The sequence actually run is cut to the dimensions and geometric requirements on the drawing.
- Finish turning of the end face and the bore
- Turning of the outside diameter
- Drilling of the bolt circle
- Machining of the sealing face
- Burr removal
Machine tools that fit (chosen by structure, not by brand)
CNC lathe
Completes the surfaces of revolution first
Machining center or drill & tap center
The bolt circle and the threads
How it is loaded and unloaded automatically
The handling method follows from part size and weight, batch size, cycle time, the number of machines and the state the blanks arrive in.
Approach 1
Gantry robot on a single machine, or tending two
Approach 2
Robot with trays
Approach 3
In-line inspection with sorting
Feeding and buffering
Inspection after machining
What this page is, and what it is not
No project case is shown for this part, and that is a statement of position, not an omission.
Product application — this page describes how this family of parts is generally machined and automated. That is manufacturing know-how that applies across the industry, not a description of one order.
Automation fit — the loading, feeding and inspection approaches listed above are options derived from structure, batch size and cycle time. The configuration actually built has to be calculated from the conditions of the project.
Verified project — no public project for this part has customer written authorization, so this page carries no project name, cycle time, output or result figure. For installed systems that are documented, see the shop-floor photos filed by business line: CNC Lathe Loading & Unloading — shop-floor photos and project cases.

Flange and fitting — frequently asked questions
What is the flange and fitting?
Flange and fitting belongs to the general machining group. A disc, or a disc-and-sleeve combination, where the end face and the bore are the main datums, usually with a bolt circle.
Where is the flange and fitting used?
Commonly seen in these industries: Automotive Components, Bearings & Transmission, EV & Liquid-Cooling Parts. The industry pages on this site set out the machining and automation entry points for those workpieces.
How is the flange and fitting machined?
The main operations are: Finish turning of the end face and the bore; Turning of the outside diameter; Drilling of the bolt circle; Machining of the sealing face; Burr removal. The actual sequence is cut to the dimensions and geometric requirements on the drawing.
Which machine tools are used for the flange and fitting?
CNC lathe — Completes the surfaces of revolution first. Machining center or drill & tap center is the alternative: The bolt circle and the threads.
Can the flange and fitting be loaded and unloaded automatically?
Yes. The usual approaches are: Gantry robot on a single machine, or tending two; Robot with trays; In-line inspection with sorting. Whether it works depends on part size and weight, cycle time and machine layout, all of which have to be calculated.
How is the flange and fitting fed automatically?
Options: Tray arrays; Rotary magazine. Feeding capacity is calculated from the parts per layer, the usable number of layers and the machining cycle; no fixed continuous running time is promised.
How is the flange and fitting inspected after machining?
Checks usually applied: Bore and end-face dimensions; Hole positions and angular spacing; Appearance. Precision dimensional measurement needs dedicated measuring equipment and has different limits from vision inspection.
How is automation for the flange and fitting planned?
Start from the part, not from a robot model: confirm the structure and the clamping datum first, then choose the machine combination and the automation method from batch size and cycle time, and finally check that feeding, buffering, inspection and safety interlocks form a closed loop.
