How Wexmar would machine this
Based on the notice title and classification, Wexmar would plan this work around centerless and surface grinding where the drawing calls for ground diameters, flatness, or fine finish. Every lot is inspected against the drawing on Brown & Sharpe CMMs.
Equipment on the floor
- Turning: 10 Mazak and Doosan CNC lathes with live tooling
- Horizontal milling: 6 Mazak horizontal machining centers, 3- and 4-axis, with pallet changers
- Swiss: 4 Maier Swiss-type lathes, bar capacity to 32 mm
- Grinding: centerless and surface grinding
- Inspection: 2 Brown & Sharpe coordinate measuring machines
Materials
The notice text references aluminum, alloy and carbon steel. Wexmar machines carbon and alloy steels, stainless steels including precipitation-hardening grades, Inconel, Monel, Hastelloy, aluminum, brass, bronze, titanium, and engineering plastics, and buys bar and plate with mill certifications. Where DFARS 252.225-7009 applies, specialty metals are sourced from qualifying melt sources and the certifications travel with the parts.
