What are the advantages of custom-made stainless steel rotating bushings using 5-axis CNC machining?

Stainless steel rotating bushings are widely used in machinery, precision instruments, and other fields, serving functions such as support, positioning, friction reduction, and transmission. Ganyuan Hardware, relying on its 5-axis CNC machining center and combining years of experience in precision stainless steel machining, has summarized the following core advantages of custom-made stainless steel rotating bushings using 5-axis CNC machining:

What are the advantages of custom-made stainless steel rotating bushings using 5-axis CNC machining?

I. Advantage of One-Time Molding of Complex Internal and External Structures

When machining bushings using traditional methods, features such as inner holes, outer circles, end faces, oil grooves, and threads often require multiple clamping operations. Five-axis CNC machining can achieve:

Complete machining of inner and outer diameters and end faces in a single clamping: All features of the bushing, such as the inner hole, outer diameter, step, end face, oil groove, keyway, threaded hole, and locating stop, are completed in the same operation.

Eliminate errors from multiple clamping operations: Ensure coaxiality of inner and outer diameters and perpendicularity of the end face to the axis.

Suitable for various complex rotating bushings:

Standard type: Straight hole bushing, stepped bushing, flange bushing

Lubricated type: Bushing with oil groove/oil hole/oil channel

Location type: Bushing with keyway, locating pin hole, and stop

Special type: Thin-walled bushing, open bushing, irregular cross-section bushing

Combined type: Bushing with thread, retaining ring groove, and sealing groove

II. Advantages of high precision and reliable fit

The precision of the rotating bushing directly determines the clearance of the rotating mechanism. Five-axis CNC machining can achieve:

Machining accuracy up to ±0.005mm, internal hole accuracy up to H6/H7 grade

Inner and outer circle coaxiality ≤ 0.01mm, ensuring smooth rotation without runout

Roundness/cylindricity controlled within 0.005mm, reducing localized wear

End face perpendicularity ≤ 0.01mm, ensuring accurate axial positioning

Surface roughness up to Ra 0.4-0.8μm (with grinding process), reducing the coefficient of friction.

Equipped with professional testing equipment such as pneumatic measuring instruments, coordinate measuring machines, roundness testers, and projectors, all goods are inspected before shipment.

Can process various stainless steel grades:

Austenitic (304/316/316L): Excellent corrosion resistance

Martensitic (410/420/440C): Heat-treatable, high hardness, good wear resistance

Precipitation hardening (17-4PH): High strength, good corrosion resistance

III. Advantages of processing lubrication structures such as oil grooves/oil holes

Rotating bushings often require the design of lubrication structures to reduce friction. Five-axis CNC machining can flexibly achieve:

Helical oil grooves: Multi-axis linkage machining of equidistant/variable pitch helical oil grooves with uniform depth.

Axial oil grooves: Machining of inner and outer circles and oil grooves in a single setup with precise positioning.

Radial oil holes: Oblique holes, intersecting holes, etc., are completed in a single positioning operation.

 IV.Advantages in machining efficiency and delivery cycle

Five-axis linkage machining improves efficiency by more than 50% compared to traditional turning + milling + drilling with multiple setups.

Small batch orders can be delivered in 3-5 days, meeting urgent repair and R&D needs.

Supports everything from 1 sample prototyping to mass production. Seamless integration

Larger batch sizes result in more significant price advantages per unit, eliminating the need for mold investment.

Surface Treatment:

Polishing/Mirror Polishing (Reduces friction, easy to clean)

Passivation (Improves corrosion resistance)

Hard Chrome Plating (Increases surface hardness and wear resistance)

Nitriding (Increases surface hardness)

Free Drawing Optimization Suggestions: Our technical team can optimize tolerances and oil groove design based on rotational speed, load, and lubrication conditions.

Packaging and Delivery: Customized rust-proof packaging and logistics delivery according to customer requirements.

After-sales Follow-up: Timely resolution of customer issues during use.
