Wexmar is a contract CNC machining supplier built for production. When an engineering or procurement team needs a machined parts supplier that can hold a print, hit a schedule, and prove conformance, we run the part from first article through long run production under one roof in Canastota, New York. Backwell MFG LLC operates as Wexmar, a machine shop equipped for repeat business rather than one-time favors.
What contract manufacturing means at Wexmar
Contract CNC manufacturing is a standing supplier relationship. You place the part with us, we own the process, and we deliver conforming components on a cadence you can plan around. That is different from a one-off shop quote. It means dedicated fixturing, documented setups, and a process that produces the same part the hundredth time it runs as it did the first. Teams come to us to outsource CNC machining so they can free internal capacity, add a production lane, or move a part off an unreliable incumbent.
Production machining and long run capacity
Our equipment is sized for production CNC machining, not just prototypes.
| Equipment | Count | Production role |
|---|---|---|
| CNC lathes (Mazak, Doosan) | 10 | Turned production parts, repeat lots |
| Mazak horizontal machining centers, 3 and 4 axis | 6 | Prismatic parts, pallet-ready volume |
| Maier MLK-32 Swiss-type, bar to 32 mm | 4 | High volume small turned parts, lights-out runs |
| Brown & Sharpe CMMs | 2 | First article and in-process inspection |
Ten lathes and four Swiss machines give us real depth for high volume CNC machining and long run machining, including horizontal machining centers that keep prismatic work moving. When a program calls for thousands of pieces on a recurring release, we have the spindle count to hold the lane without displacing your other parts. See our machine list for the full floor.
Blanket purchase orders and scheduled releases
Production buyers rarely want to re-quote every lot. We support blanket purchase orders with scheduled releases, so you lock pricing and lead time across an annual volume and pull quantities as your demand signals arrive. That keeps your finished goods lean while we hold raw material and capacity against the agreement. Kanban-style pulls, min and max triggers, and firm release windows all work with our scheduling. The blanket structure is what turns a job shop quote into a dependable CNC machining vendor relationship.
Repeatability and process control
Repeatability is the whole point of a production supplier. We control it with documented setups, dedicated fixtures and tooling, controlled programs under revision, and first article verification before a lot runs. In-process checks on the floor catch drift early, and we gauge to the characteristics that matter on your print. Where a print calls out key characteristics, we watch those features across the run rather than inspecting once and hoping. Our inspection and quality program and two Brown & Sharpe CMMs back every production part with measured evidence.
The supplier relationship, materials, and quantities
We machine carbon and alloy steels, stainless grades including 303, 304, 316, and 17-4 PH, Nitronic 50 and high-nickel alloys including Inconel, aluminum, brass, bronze, titanium, and engineered plastics. Material certifications and DFARS-relevant material sourcing are available when your program requires traceability. Quantities run from one-off prototypes through long production, so we can prove a part on a first article and then scale it without changing suppliers. Our quality system is ISO 9001 aligned, not certified, and we maintain NIST SP 800-171 with 110 of 110 in SPRS, which matters to defense and aerospace buyers qualifying a new machined parts supplier.
