· Product Overview

· Core Specifications

• Material: Premium Stainless Steel (304/316 Grade)Offers superior corrosion resistance, sterile compatibility (for medical/clean environments), and high mechanical strength, suitable for harsh or precision-driven operating conditions.
• Manufacturing Standard: ISO 9001-Certified Precision CNC Machining Process
  • Dimensional Tolerance: ±0.02mm, ensuring seamless concentricity and fit between nested cylindrical layers.
  • Fabrication Techniques: Integrates multi-axis CNC turning (for nested cylindrical geometry), precision drilling (for alignment/mounting holes), and surface polishing (for smooth internal/external surfaces).

· Application Scenarios

• Hydraulic & Pneumatic Systems: As valve housings, cylinder liners, or fluid control core parts, ensuring leak-proof performance and precise fluid flow.
• Precision Machinery: For bearing retainers, shaft alignment sleeves, or core structural components in CNC machines, robotic arms, and measurement equipment.
• Medical Equipment: In diagnostic tools, surgical instrument sub-assemblies, or lab machinery, leveraging stainless steel’s biocompatibility and sterile properties.
• Industrial Automation: As critical alignment parts in automated production lines, conveyor systems, and material handling equipment.

· Production Process Introduction

1. Raw Material Sourcing: Procure certified 304/316 stainless steel bars with uniform metallurgical properties and dimensional consistency.
2. Precision CNC Machining:
   • Multi-Axis CNC Turning: Shape the outer and inner nested cylindrical layers with micron-level concentricity.
   • Precision Drilling: Machine small alignment/mounting holes to exact positional specifications.
   • Surface Polishing: Achieve smooth, burr-free internal/external surfaces for optimal mechanical interaction and fluid flow.
3. Quality Inspection: Conduct CMM (Coordinate Measuring Machine) scans to verify concentricity, dimensional accuracy, and hole positioning; perform material corrosion-resistance tests.
4. Packaging Preparation: Individually wrap the component in anti-scratch film and place it in a custom foam-lined box to protect polished surfaces and precision features.

· Packaging and Shipping Methods

• Packaging: Each component is protected with anti-scratch film and packed in a custom foam-lined box (to prevent surface damage and maintain dimensional integrity). Bulk orders are secured in partitioned containers with protective separators.
• Shipping: We offer flexible logistics options: Express Delivery (DHL/FedEx/UPS, 3–5 business days), Air Freight (7–10 business days), or Sea Freight (20–30 business days). All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): MOQ is 50 pieces for standard designs. Custom designs require a MOQ of 100 pieces.
• Lead Time: Standard lead time is 7–12 working days after order confirmation. Expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full OEM/ODM customization is supported—we can modify nested dimensions, hole positions/quantities, material grades (e.g., high-strength 316L), and surface finishes based on your technical drawings or sample specifications. Our CNC engineering team collaborates closely to deliver tailored solutions.
