CNC Turning
Sleeves, rings, bushings, shafts and other cylindrical parts.
Capabilities
Machining and partner-process capabilities
RF Machining separates in-house machining and Stellite hardfacing from processes arranged through long-term partners, so buyers can review capability boundaries clearly during RFQ communication.
Drawing-based custom machining
Typical machining range
Machining range confirmed from drawings
For sleeves, collars, rings, bushings, glands and other pump or valve components, RF Machining confirms size, material, tolerance, surface treatment and batch quantity from the drawing or sample before quotation.
- Turned sleeves, collars, bushings, wear rings and gland-style ring components
- Milled, drilled, tapped and slotted features when defined by the drawing
- Stellite / cobalt-based alloy hardfacing considered in-house when the overlay area is defined
- Small and medium batches for OEM, MRO and aftermarket spare-part supply
- Larger or tighter-tolerance parts are confirmed case by case before quotation
In-house
In-house machining and Stellite hardfacing capabilities
These machining steps are handled as part of RF Machining's workshop production and process planning for drawing-based parts. Stellite / cobalt-based alloy hardfacing is considered when the drawing defines the overlay area, base material, machining allowance and inspection requirements.
CNC Milling
Milled faces, features, holes and non-standard component geometry.
Drilling & Tapping
Drawing-defined holes, threads and assembly features.
Thread Machining
Internal and external thread requirements according to drawings.
ID, OD, Face & Groove Machining
Controlled fits, end faces, steps and grooves.
CNC Slotting
Internal slotting and related drawing-defined features.
Partner processes
Processes arranged through long-term partners
Grinding, heat treatment, QPQ, hard chrome plating and thermal spray coating requirements can be arranged through long-term process partners when specified by the drawing or RFQ.
Partner-process suppliers are managed through long-term working relationships and order-specific requirements. Supplier names, customer names, logos, drawings and confidential order details are not published.
Grinding
Can be arranged through long-term process partners.
Heat Treatment
Can be arranged according to drawing and material requirements.
QPQ
Nitriding-related surface requirements can be arranged through partners.
Hard Chrome Plating
Can be arranged for drawing-defined surface requirements.
Other Overlay / Wear-Resistant Surface Requirements
Other overlay requirements can be reviewed according to drawing and process scope.
Nickel & Thermal Spray Coating
Can be arranged for specified surface or corrosion requirements.
Documents
Inspection and document support
Document level is confirmed according to drawing, RFQ and order requirements. RF Machining keeps this practical and order-specific.
We check dimensions with calipers, micrometers, bore gauges and roughness meters according to part geometry and tolerance requirements. Material certificates and inspection reports can be provided upon request.
- Material certificates upon request
- First article reports upon request
- Key-dimension inspection records
- Hardness, roughness and runout checks when required
- Surface-treatment records when applicable
- Packing photos upon request
