Inner Barrel CNC Milling And Turning Services

Inner Barrel – CNC Milling and Turning Services for Precision Stainless Steel Components

Our inner barrel is manufactured through advanced CNC milling and turning services to achieve tight tolerances, excellent surface finish, and stable performance in demanding applications.

Product Overview

This stainless steel inner barrel is produced from corrosion‑resistant SUS316, suitable for use in harsh environments and high‑precision assemblies. Through a combined CNC milling and turning workflow, the component maintains dimensional accuracy and consistent concentricity along the entire barrel length.

Features and Benefits

The inner barrel is designed for customers who require stable performance and repeatable accuracy in medium to large production runs. Key characteristics include:

• High corrosion resistance thanks to SUS316 stainless steel
• Excellent roundness and concentricity along the bore
• Consistent wall thickness for optimized flow and mechanical strength
• Smooth internal and external surfaces prepared for further finishing or coating
• Stable dimensions across batches, suitable for mass production

Typical applications include:

• Pneumatic and hydraulic components
• Precision mechanical assemblies
• Industrial machinery parts
• Custom OEM inner barrel requirements

CNC Milling and Turning Services

Jiou Tian provides comprehensive CNC milling and turning services for complex stainless steel components such as inner barrels. From prototype to mass production, we can machine parts according to your 2D drawings or 3D CAD files, including:

• OD/ID turning and facing
• Grooves, slots, and engraving by CNC milling
• Threading on internal or external surfaces
• Tolerance control according to customer specifications
• Support for secondary operations such as grinding, polishing, and assembly

Our process flow for this inner barrel typically includes:

1. CNC turning of the raw material to form the primary outer and inner diameters
2. CNC milling for engraving, ports, flats, keyways, or customized external features
3. Deburring and cleaning
4. Dimensional inspection according to the agreed quality standards

Material: Stainless Steel SUS316

SUS316 stainless steel is widely used in industrial, medical, and marine environments due to its resistance to corrosion and chemical attack. It is suitable for:

• Components exposed to moisture or aggressive media
• Parts requiring both strength and durability
• Applications where hygiene and cleanliness are important

Using SUS316 for the inner barrel helps extend service life and maintain performance over long‑term operation.

Custom Inner Barrel Manufacturing

We accept customized inner barrel projects based on:

• Customer drawings and specifications
• Required tolerances and surface roughness
• Specific material grades (SUS316 or other stainless steels and metals)
• Quantity ranges from prototypes to mass production

Our CNC milling and turning services can support complex geometries, multiple machining steps, and integrated post‑processes such as grinding or surface treatment, so that customers receive ready‑to‑assemble components.

Quality and Inspection

Each inner barrel is produced under a controlled manufacturing process with:

• Dimensional inspection based on customer drawings
• Consistency checks across batches
• Documentation and records available upon request

This helps ensure that every shipment of inner barrels meets the agreed specification and performance requirements.
