Case Studies — How We Process Different Parts
Six typical parts from our machines, and the process and inspection steps behind each one — methods we use every day, from DFM review to final inspection.
How Do We Process Different Parts?
Each card describes a real machining method and the checks that keep the part within drawing — not a sales story.
DFM Review Catches Drawing Problems Before Cutting
Before any metal is cut, our engineers review every new drawing: tolerances, wall thickness, internal corners, threads and depth-to-diameter ratios. Issues go back as marked-up feedback with a suggested fix, so production starts from a manufacturable drawing.

Swiss-Type Lathes for Small, Slender Parts
Small-diameter, long parts deflect on ordinary CNC lathes. On Japanese Tsugami Swiss-type automatic lathes the guide bushing supports the bar right at the cutting point — holding concentricity and surface finish on slender shafts and pins, from first article to full batch.

Anodized Housings, Consistent Batch to Batch
Appearance housings run through qualified anodizing partners, then come back to our bench. We check color against the approved sample, surface roughness, dimensions after coating and cosmetic faces — so repeat orders match the first approved batch.

Turned Brass Fittings: Thread and Sealing Surface Control
Brass fittings usually fail on threads and sealing faces, not on the easy diameters. We gauge thread fit, keep sealing surfaces smooth and flat, and check critical features in-process per drawing — parts that assemble and seal the first time.

Prototype Aluminum Enclosure: From 1 Piece to Repeat Orders
A first enclosure can start from a single piece. We machine the prototype from the same 3D model production will use and ship it with a first-article inspection report. Process and fixturing stay on file, so repeat batches are the same part — not a re-development.

Salt-Spray Tested Plated Parts for Outdoor Use
Plated parts for outdoor equipment need corrosion resistance you can verify. Plating runs through qualified partners, then our salt-spray tester checks coating performance against the specified test hours, followed by visual and dimensional inspection before packing.

About These Case Studies
Each study describes the machining method and inspection steps we use for that type of part. Drawings, first-article reports and customer references are shared during technical discussions, under NDA when needed — we do not publish customer names or drawings without permission.
