Industry Sector

Boeing's Crew Space Transportation (CST)-100 Starliner spacecraft is designed for missions to low Earth orbit and the International Space Station. Developed in collaboration with NASA's Commercial Crew Program, it can carry up to seven passengers and small cargo. The Boeing Starliner uses an innovative weldless structure and is reusable up to 10 times with a six-month turnaround time.

With decades of experience in the aerospace industry, TARUS 5-axis CNC machines are in widespread use by manufacturers of aerospace tooling including layup molds, machining fixtures, assembly jigs and friction stir welding fixtures - as was used for the Boeing Crew Space Transportation (CST)-100 Starliner spacecraft.

TARUS 5-axis CNC mills can be equipped with standardized production CNC controls and are ideal for milling aluminum alloy aero-structures, racks, and platforms, while TARUS CMM are used for fixture build and verification of tooling and components.  


Aluminum Alloy Airframe Components

The majority of most aircraft are constructed of CNC machined aluminum alloy components. TARUS offers a variety of 5-axis CNC milling machines ideal for these components.


Assembly Fixtures

Precision assembly fixtures are critical to successfully manufacture aircraft and aerospace vehicles.


Bond Fixtures/Layup Molds

Bond fixtures and layup molds come in a variety of types, including Invar, steel, aluminum, carbon fiber, and hybrid Invar and composite. TARUS 5-axis CNC machines are commonly used to in the aerospace tooling industry to manufacture these tools.


Composite Air Frame Components and Engine Nacelles

Molded composite components are increasingly important for aerospace manufacturing. TARUS 5-axis CNC milling machines are ideal for trimming and drilling those composite components.


Friction Stir Welding Fixture

FSW is a process of joining two pieces of metal together using friction rather than heat welding. Due to the forces placed on the part, proper fixturing is critical for producing high quality, precision components.



Hydroforming is a specialized type of die forming that uses a high pressure hydraulic fluid to press room temperature working material into a die. Hydroforming allows complex shapes with concavities to be formed, which would be difficult or impossible with standard solid die stamping. Hydroformed parts can often be made with a higher stiffness-to-weight ratio and at a lower per unit cost than traditional stamped or stamped and welded parts. Virtually all metals capable of cold forming can be hydroformed, including aluminum, brass, carbon and stainless steel, copper, and high strength alloys.


Impellers/Turbine Components

Impellers have wide ranging application from pumps, to turbines, to turbochargers. Machining impellers benefits from simultaneous 5-axis milling, and requires extremely tight-tolerance geometry. The TARUS UNIMAX series is perfect for this application.

Application - Aerospace Impeller - TARUS


Precision machined aerospace components are measured using a coordinate measuring machine (CMM) after manufacturing and before assembly to ensure quality and precision.


Landing Gear

Aircraft landing gear are comprised of many large critical components that require machining on 5-axis CNC milling machines.


Production Assembly Fixtures

Production assembly fixtures are used to assemble aerospace bodies and interior components. These highly precise gauges and jigs are assembled from machined components and then verified by CMM.


Service and Testing Fixtures

Aerospace companies utilize a variety of fixtures to test, maintain, and redeploy vehicles for reuse. TARUS 5-axis milling machines are used to the components for these fixtures.


Trim and Drill Fixtures

Composite and aluminum airframe components require proper fixturing in order to drill holes and trim edges precisely without damaging the workpiece.


Turbine Discs

Turbine discs require simultaneous 5-axis milling in order to produce their very complex shapes. The rotary table and swiveling milling head configuration make the TARUS UNIMAX a good choice for this application.
