Secondary Operations

In addition to a fully-equipped Metallurgical Laboratory to provide complete in-house carbon and microstructure analysis, our facility includes a Secondary Operations Department offering a variety of machining operations to extend both the shape and tolerance capabilities of the PM process. Complex features that can not be molded, such as cross-holes, threads, and thin wall sections, can be formed with a secondary machining operation after sintering. In some cases only one machining pass is required, since PM components can be sintered to the proper size, leaving the optimum amount of removal stock.

Our in-house capabilities include broaching, milling, turning, drilling, reaming, and tapping. To facilitate machining multiple features and automated operations, SSI-Sintered Specialties has a variety of CNC machine tools, including lathes, tapping machines, and machining centers. Automated loading systems on machining equipment are also utilized making the Secondaries Department well suited to high-volume, value-added machining operations.
