· Product Overview

· Core Specifications

• Material: Premium Stainless Steel (304/316 Grade)Provides superior corrosion resistance, high mechanical strength, and compatibility with sterile/harsh operating environments (e.g., industrial production floors, cleanrooms).
• Manufacturing Standard: ISO 9001-Certified Precision CNC Machining Process
  • Dimensional Tolerance: ±0.02mm, ensuring seamless fit with mating holes, bearings, and assembly interfaces.
  • Fabrication Techniques: Integrates CNC Turning (for stepped cylindrical profiles) and Precision Grinding (for ultra-smooth surface finish), plus Passivation (to enhance corrosion resistance and surface durability).

· Application Scenarios

• Industrial Assembly Lines: As positioning pins for jigs, fixtures, and component alignment in automated production processes.
• Robotics & Automation: For linkage guides, joint alignment pins, and structural connection parts in robotic arms and conveyor systems.
• Precision Machinery: As bearing guides, shaft alignment pins, and mounting components in CNC machines, optical systems, and measurement tools.
• Electronic Enclosures: For securing internal components (e.g., circuit boards, sensors) in industrial control panels and custom electronic devices.

· 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:
   • CNC Turning: Shape the stepped cylindrical profile with micron-level accuracy to match assembly fit requirements.
   • Precision Grinding: Refine the surface to achieve an ultra-smooth finish (critical for low-friction motion applications).
   • Passivation: Apply a surface treatment to boost corrosion resistance and extend long-term service life.
3. Quality Inspection: Conduct CMM (Coordinate Measuring Machine) scans (to verify dimensional accuracy), straightness tests, and surface roughness audits.
4. Packaging Preparation: Individually wrap each pin in anti-scratch film and place in custom foam-lined boxes to protect the smooth surface and precision dimensions during transit.

· Packaging and Shipping Methods

• Packaging: Each pin is protected with anti-scratch film and packed in foam-lined boxes (to prevent surface damage). Bulk orders are secured in partitioned containers with protective separators to avoid contact wear.
• Shipping: Flexible logistics options include 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.
