Custom CNC Cylindrical Pin, High Precision Tool Assembly Positioning Pin
Product Overview
Custom CNC Cylindrical Pin is a high-precision mechanical positioning component widely used for tool assembly, fixture calibration and industrial equipment matching. Manufactured by professional CNC turning and precision machining, this cylindrical pin features accurate dimensions, smooth surface and excellent consistency. It is designed for precise positioning, limiting and fixing work, effectively improving assembly accuracy and stability of mechanical tools and automation equipment.
Key Features
High Precision CNC Machining
Each pin is processed by precision CNC equipment with strict tolerance control. The pin body features high straightness, smooth surface without burrs, ensuring tight fitting and accurate alignment during assembly. It meets the high-precision matching requirements of tooling and mechanical structures.
Stable Mechanical Performance
Made of high-quality industrial metal materials with good hardness and toughness. The cylindrical pin is resistant to compression and friction, not easy to deform after long-term repeated plugging and positioning work, maintaining stable working performance.
Excellent Positioning Effect
Standard cylindrical structure ensures uniform stress and accurate limiting. It effectively reduces assembly deviation, avoids component shaking and displacement, and greatly improves the overall consistency and stability of tool assembly.
Strong Customization & Interchangeability
Support custom diameter, length, groove, step and surface treatment according to customer drawings and samples. Standard finished pins have good interchangeability, convenient for quick replacement and batch assembly production.
Application Scope
✅ Precision tooling fixture positioning and limiting pins
✅ Mechanical equipment assembly calibration components
✅ Automation jig and tool assembly fixing pins
