What Gensun offers
Gensun Precision Machining, based in Dongguan, China, is a precision manufacturer of high-tolerance metal components and assemblies. It runs CNC milling and turning alongside sheet metal, stamping, die casting, and precision casting, and it holds recognized quality certifications. Gensun works in aluminum, stainless, titanium, brass, and specialty alloys, serving aerospace, medical, semiconductor, and telecom customers. For buyers comfortable sourcing precision parts overseas across several processes, it is a capable supplier.
Where Wexmar fits
Wexmar is the domestic equivalent of the machining half of that picture. It is a US shop that turns, mills, and Swiss-machines metal parts, with the quote and the work in the same building.
Wexmar is a US CNC machine shop in Canastota, NY that ships nationwide. The shop runs 10 CNC lathes, 6 Mazak horizontal machining centers (3 and 4 axis), and 4 Maier MLK-32 Swiss lathes turning bar stock to 32mm diameter, with 2 Brown & Sharpe CMMs for in-house inspection. Work runs from one-off parts through long-run production. Wexmar is SAM registered (CAGE 16AD7), NIST 800-171 scored 110 of 110 in SPRS, DFARS-relevant, Buy American, and Made in USA. Quality is ISO 9001-aligned.
Gensun adds stamping and casting that Wexmar does not offer, so a stamped or cast part belongs there. Wexmar's focus is US turned and milled production and Swiss turned parts, with in-house CMM inspection and federal registrations that support Buy American and defense-adjacent orders.

Which to pick
If a job mixes machining with stamping or casting and overseas sourcing is fine, Gensun covers that range. If you need turned or milled metal parts made in the United States, held to a CMM, and backed by federal registrations, a domestic direct shop keeps the chain short. Wexmar quotes prototypes and production from one drawing. See CNC turning or request an instant quote.
Materials, tolerances, and lead time
Wexmar machines common and specialty metals for turned and milled work, including aluminum, stainless, carbon and alloy steels, brass, and bronze, with material choice driven by the drawing. The four Maier MLK-32 Swiss lathes handle small, tight-tolerance turned parts in bar stock to 32mm diameter, while the 6 Mazak horizontal machining centers cover 3 and 4 axis milled work. Every job can be checked on the shop's two Brown & Sharpe CMMs before it ships, and first-article and in-process inspection scale with the run. Lead time tracks material availability and quantity rather than a queue in someone else's plant, and the same drawing that priced the job runs it from prototype through production.
