Stainless Steel Material Options
304 stainless steel is a practical choice for general industrial precision pins. For applications requiring improved corrosion resistance, 316 or 316L can be considered.
Where higher wear resistance is needed, a suitable hardenable stainless steel grade may be a better option.
Precision Turned Diameters
Critical pin diameters are machined according to the required fit. For locating pins, diameter tolerance and roundness directly affect how the pin fits into its mating hole.
Custom Stepped and Grooved Designs
We machine stepped pins with multiple diameters, shoulders, retaining ring grooves, and threaded sections.
These features allow the pin to locate, retain, or connect components within a compact assembly.
Smooth Edges for Assembly
A small burr on a precision pin can damage a mating hole or interfere with insertion.
We pay attention to chamfers, groove edges, and cross-drilled holes, especially on pins intended for repeated assembly.
Made to Customer Drawings
We manufacture custom pin dimensions and profiles rather than limiting customers to standard catalog sizes.
Our precision components for robot joints demonstrate related machining requirements for compact mechanical assemblies.
Manufacturing Processes
CNC Turning
Our precision CNC turning capabilities support straight pins, stepped diameters, grooves, shoulders, and threaded ends.
CNC Milling
Our CNC milling services support cross holes, slots, flats, and other non-cylindrical features.
Precision Drilling and Tapping
We machine axial holes, cross holes, and threaded features according to customer drawings.
Grinding and Surface Finishing
For applications requiring tighter fits or finer surface finishes, grinding can be considered as an additional finishing process.
Polishing and passivation are available according to the material and application requirements.
Dimensional Inspection
We focus inspection on critical diameters, shoulders, overall length, concentricity, and edge condition.
If the pin requires a press fit, sliding fit, or specific surface hardness, please include those requirements on your drawing.
We'll review the machining feasibility and provide a quotation based on your specifications.
