Small Bushing Turning With Thin-Wall Control | New Partner
Small bushings and sleeves: bore and outside diameter turning, concentricity on thin walls, bar feed or tray feeding and dimensional checks after turning.
Small bushing machining and automation
Small bushing (Shaft sleeve, Bushing, Sleeve): A thin-wall sleeve where concentricity between the bore and the outside diameter is held tight ... 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
Small bushing (Shaft sleeve, Bushing, Sleeve) belongs to the precision hardware / general group. A thin-wall sleeve where concentricity between the bore and the outside diameter is held tight; the part distorts easily.
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 bore
- Finish turning of the outside diameter
- End faces
- Chamfering
- Burr removal
Machine tools that fit (chosen by structure, not by brand)
CNC lathe
Turning of sleeve-type bodies of revolution
Swiss-type machine
Small sizes in production quantities
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 with tray feeding
Approach 2
Automatic bar feed on the Swiss-type machine
Approach 3
One robot tending two machines
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.
Business lines that cover this part

Small bushing — frequently asked questions
What is the small bushing?
Small bushing belongs to the precision hardware / general group. A thin-wall sleeve where concentricity between the bore and the outside diameter is held tight; the part distorts easily.
Where is the small bushing used?
Commonly seen in these industries: Bearings & Transmission, Precision Hardware & Fasteners. The industry pages on this site set out the machining and automation entry points for those workpieces.
How is the small bushing machined?
The main operations are: Finish turning of the bore; Finish turning of the outside diameter; End faces; Chamfering; Burr removal. The actual sequence is cut to the dimensions and geometric requirements on the drawing.
Which machine tools are used for the small bushing?
CNC lathe — Turning of sleeve-type bodies of revolution. Swiss-type machine is the alternative: Small sizes in production quantities.
Can the small bushing be loaded and unloaded automatically?
Yes. The usual approaches are: Gantry robot with tray feeding; Automatic bar feed on the Swiss-type machine; One robot tending two machines. Whether it works depends on part size and weight, cycle time and machine layout, all of which have to be calculated.
How is the small bushing fed automatically?
Options: Tray arrays; Bar feeding. 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 small bushing inspected after machining?
Checks usually applied: Inside and outside diameters; Concentricity; Appearance. Precision dimensional measurement needs dedicated measuring equipment and has different limits from vision inspection.
How is automation for the small bushing 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.
