Openex expands large-part CNC milling for oversized industrial components

Openex is positioning its Xiamen manufacturing operation around large-part CNC milling for heavy industrial equipment. The company says its integrated machining, fabrication and inspection capacity is built to handle oversized parts up to 250 tons and support sectors from energy to marine engineering.

Why it matters: - Oversized industrial equipment needs machining that can hold tight tolerances across very large surfaces and interfaces. - Large-part CNC milling is becoming more important as sectors like energy, mining, marine engineering, transportation, power generation and heavy machinery build larger components. - Openex is aiming to serve that demand with one production flow that covers fabrication, machining, inspection and finishing.

What happened: - Openex said it has developed large-part machining capabilities in Xiamen, Fujian, China. - The company said its large CNC machining and planer milling operations can handle components weighing up to 250 tons. - Openex said its machining envelope reaches 25,700 mm by 8,000 mm. - More information is available at the company's announcement.

The details: - Openex said its equipment includes large gantry machining centers, horizontal boring mills and vertical turning and milling machines. - The company said more than 16 large gantry machining centers are part of its machining capacity. - Openex said its large horizontal boring mills provide an X-axis range of up to 25.7 meters. - The company said its vertical turning and milling equipment can accommodate workpieces with diameters up to 22 meters. - Openex said it uses ZEISS coordinate measuring machines and a Leica AT901 laser tracker for dimensional inspection. - The company said these systems support measurement of large components and complex geometries. - Openex said its cutting capabilities include waterjet, laser, plasma, flame cutting and sawing. - The company said its fabrication services include welding, plate rolling, bending, hydraulic pressing, thermal stress relieving, sandblasting and painting. - Openex said its applications include pressure vessels, heat exchangers, vacuum chambers, sterilization chambers, industrial ductwork, reservoir tanks, wind turbine components, material handling equipment and large steel structures. - The company said it supports mining and engineering, oil and gas, pulp and paper, automotive, bridge construction, marine engineering, renewable energy, power generation, aerospace and other industrial fields.

Between the lines: - Large-part machining is not just about bigger machines; it also depends on fixturing, thermal control, measurement accuracy and production sequencing. - Openex is framing CNC milling as one stage in a broader industrial process that starts with cutting and fabrication and ends with inspection and shipment. - That model matters for welded structures and other components that can shift dimensionally before final machining.

What's next: - Demand for large CNC milling is likely to grow as industrial systems get larger and design tolerances stay tight. - Openex said the next stage of large machining will require systems that can manage material prep, fabrication, machining, inspection, finishing and logistics in one workflow. - The company is positioning its capacity for that shift as heavy industry pushes for larger, more precise components.

The bottom line: - Openex is building a large-part machining platform around scale, precision and end-to-end manufacturing support for heavy industry.
