Custom CNC Cylindrical Locating Pin, Precision Fixture Assembly Tool Parts
Product Overview
Custom CNC Cylindrical Locating Pin is a high-precision tool accessory widely used for fixture positioning, equipment alignment and mechanical assembly. Adopting advanced CNC precision machining technology, this cylindrical pin features accurate dimensions, smooth surface and excellent consistency. It effectively improves assembly accuracy, reduces positioning deviation, and ensures stable and repeatable matching for industrial tooling and automation equipment.
Key Features
High Precision CNC Machining
Processed by multi-axis CNC equipment with strict tolerance control. The pin body owns high straightness and roundness, smooth surface without burrs. It achieves precise fitting and guarantees stable positioning accuracy for long-term repeated assembly.
Reliable Structural Performance
Made of high-quality industrial raw materials with good hardness and wear resistance. The pin is not easy to deform or wear under continuous extrusion and friction, maintaining stable mechanical performance in daily industrial working conditions.
Accurate Positioning & Firm Locking
Standard cylindrical structure enables close matching with mounting holes. It effectively limits component displacement and shaking, improves overall assembly stability, and ensures consistent product assembly precision during mass production.
Strong Custom Compatibility
Support full customization according to customer drawings and samples, including diameter, length, step shape, groove structure and surface treatment. Both standard and non-standard precision pins are available to meet diverse tooling matching needs.
Application Scope
✅ Precision fixture and tooling positioning pins
✅ Automation equipment assembly locating parts
✅ Mechanical equipment calibration and fixing pins
✅ Industrial precision machinery matching accessories
✅ Custom non-standard CNC machining tool parts
