Machining expertise
From rotational parts to complex machined features
Our facility handles both high-mix, low-volume prototypes and repeat production runs, with attention to geometry and finish so parts arrive ready for your assembly line.
CNC Turning
We specialize in rotationally symmetric parts such as shafts, pins, collars, and spacers. Turning centers handle complex features including grooves, chamfers, and threads.
Programming directly from your CAD files supports consistency across the production run and can reduce the need for incoming quality inspections.
CNC Milling
For non-rotational features such as pockets, slots, or flat surfaces, milling provides the precision needed for brackets, blocks, and custom mounting hardware.
We work to your specified tolerances so components integrate correctly into the final product.
Secondary processing
Finished components prepared for real-world use
A part is only as good as its finish. We provide secondary operations for environmental performance, safe handling, clean aesthetics, and traceability.
Precision Hole Features
Drilling and reaming for accurate bores.
Threading
Internal and external threading to your specified pitch.
Surface Conditioning
Deburring and polishing for safe handling and clean aesthetics.
Protective Coatings
Passivation, anodizing, plating, and Black Oxide options to enhance corrosion resistance.
Identification
Laser marking for part numbers or batch traceability.
Design guidance
Select the right geometry and material for your project
The right component choice can influence assembly performance, product size, and manufacturing cost.
Brass Spacers
Excellent machinability and natural corrosion resistance make brass ideal for electrical conductivity and aesthetic requirements in instruments.
Stepped and Flanged Designs
These profiles can reduce component count and support more compact product designs.
Threaded Options
Threaded components simplify installation in robotics and electronics housings where secure mounting is critical.
If you are evaluating a design, share your drawing with us. We review specifications to identify manufacturing efficiencies that can reduce lead times or production costs without compromising quality.
