Large Conventional Machining Services

Signal Metal Large Machining Facility

Specializing in large weldment machining, a portion of our 120,000 ft2 of manufacturing space here at Signal Metal Industries, Inc. is devoted to our large, heavy-duty horizontal boring mills and vertical turning lathes. In addition to supporting our comprehensive fabrication capabilities, our large conventional machining services are offered as a standalone job shop service as well. With our wide range of machinery and equipment, we manage projects that involve oversized and heavy workpieces as well as smaller weldments and sub-assemblies.

At the center of our operations are two floor-type horizontal boring mills with 6" spindles and 120,000 lbs. of table capacity as well as an addition mill with a 7" spindle and 150,000 lbs. of table capacity. We also have five large turret head vertical turning lathes. These machines are equipped with positioning and lifting systems that allow us to easily manipulate workpieces to maintain an exceptional level of precision and accuracy.

With their extensive experience, our machinists have a deep understanding of the challenges associated with large part machining and are intimately familiar with machine operations. They tap into their strong background to design fixtures that accommodate parts with challenging geometries, and they are adept at the extensive tooling setups often required for large part machining. Using tools such as digital readouts and Faro laser devices our technicians continually monitor the quality of the workpieces while they are still on the machine.

We also have large, 17' wide x 33' long x 23' tall thermal stress relieving furnace on site. This allows us to stress relieve workpieces prior to machining, which enables us to consistently uphold exceptionally close tolerances across large dimensional spans.
