ITAR Registered
As a US-based, US-owned facility registered with the U.S. State Department's Directorate of Defense Trade Controls (DDTC) and compliant with ITAR, we machine to print on defense articles and controlled unclassified information (CUI) for non-export, U.S.-based work, with secure procedures for handling your prints.
PRECISION FOR THE TOUGHEST METALS
Conventional Machining
Despite the difficulty, our extensive machining experience allows us to machine materials other companies cannot. Some of the conventional machining methods we employ include saw cutting, turning, boring, tapping, threading, multi-axis milling, and grinding.
BUILT TO PRINT, ANY VOLUME
Custom Machined Parts
Midwest Tungsten houses a complete machine shop capable of machining parts to customer specification. We can accept both small and large run jobs of custom machined parts. We also have a full inspection department to assure your parts are correct. Material certifications for industrial products are available upon request with purchase. Dimensional inspection reports can also be obtained by request
FAST SHAPING FOR THICK STOCK
Water Jet Cutting
Waterjet cutting is best for smaller volume parts or for parts of thicker stock. This process is relatively quick, but is not suitable for parts with tight dimensional tolerances. For parts with high tolerances, we suggest EDM cutting.
INTRICATE DETAIL, TIGHT TOLERANCES
EDM Drilling & Cutting
Because tungsten is a very hard material, conventional machining is often difficult or impossible. We utilize Electrical Discharge Machining (EDM) to overcome this difficulty. EDM machining allows for intricate cutting with tight tolerances and allows us to create holes smaller and deeper than would otherwise be possible in tungsten.
ULTRA-PRECISE SURFACE FINISHES
Grinding
As tungsten is difficult to conventionally machine, we often use grinding to manufacture parts with tight tolerances or fine surface finish requirements.
CUSTOM FORMS AND FILAMENTS
Winding & Bending
Our current capabilities include the winding of evaporation filaments, electron beam, and ion beam filaments with both single and multistrand wire. Much of our computer-controlled equipment was built in-house to guarantee precision and repeatability. In addition to winding, we form wire into a variety of shapes using CNC benders, four-slides, and custom jigs and fixtures
VERSATILE SHEET METAL FABRICATION
Shearing, Punching, & Stamping
Midwest Tungsten Service has numerous stamping and forming presses, brakes and shears. We also have CNC punches and tack welding equipment to form refractory metal sheet into the products that you need.
