Automated Airflow Testing

 

Airflow testing is the measurement of the movement of air through a specific product or component, Usually tested for an air moving device such as a blower or fan. Airflow testing is also an absolute must for new turbine engine blades, shroud, manifold, combustors, nozzles, and more.

Union Machine is capable of building a fixture customized to your specifications in a short period of time and in a cost-efficient manner.

Laser Cutting

Laser cutting allows manufacturers to cut into various materials and create patterns and designs. It’s ideal for applications that require specialized or intricate parts since it does not require custom-designed tools like other fabrication methods.

Laser Drilling

Laser Drilling

Laser drilling is the process of creating holes in a material with a fiber laser beam. The holes may be thru-holes or small dents to roughen material and prepare it for coating. Manufacturers have total control over the laser drill’s intensity, heat, and duration, and can create a variety of holes and impressions on a part. 

Spark Erosion Grinding (Honeycomb Grinding)

Spark erosion grinding systems remove metal stock using AC current. The process relies on EDM technology, which allows manufacturers to arc-grind profiles onto metal parts. Aerospace and other professionals often opt to repair and reshape parts using spark erosion grinding rather than replacing expensive, specialized components. Honeycomb grinding creates a burr-free, honeycomb finish as well as minimal cutting force strain on parts.

Contour Machining

Airflow Testing

Our contour machining services produce continuous curves in the material. Many industrial applications that require ultra-precise components benefit from contour machining since it creates very intricate parts when necessary.

CNC Turning

CNC turning involves using a stationary cutting tool to alter a rotating workpiece. The turning process creates symmetrical parts with cylindrical features. Many clients opt to use this for high-volume runs because adding a bar feeder to the turning process makes process automation easy.

CNC Milling (5-Axis)

In CNC milling, a rotating cutting tool cuts a stationary workpiece. Parts that don’t involve critical cylindrical features may benefit from milling instead of turning. 2 or 3 axis CNC milling machines require manual workpiece rotation; 4 and 5 axis CNC milling machines can be automated.
