SMEA has a modest number of CNC machines and
machining centers including machines as big as the 5-axis Cincinnati
30V (4.2m x 1.7m x 0.6m x ± 250). More machines are being
added under its current expansion programme.
SMEA is fully capable of programming its CNC machines. Its CAD/CAM Centre is currently equipped with 1 x CATIA Station, 3 x Master CAM Stations, 1 x Smart CAM Station and 1 x Edge CAM Station. These stations are linked directly to the CNC machines.
SMEA's Sheetmetal Shop is equipped with a CNC Router, Hydraulic
Rubber Presses, Shrinking Machines (electric and pneumatic), NC
Press Brake, NC Hydraulic Guillotine, Deburring Machine, Stretch
Forming Machine and Manual Routers. In conjunction with the heat
treatment and surface treatment facilities, this is capable of
fabricating most of the aerospace sheetmetal parts.
SMEA is fully capable of manufacturing and certifying assembly jigs to manufacturer drawings. Assembly personnel are trained to handle close tolerances and high quality finish.
SMEA is equipped with civil certified welders to handle aircraft
welding. Our welding facilities include 3 x MIG Welding Eqpt,
6 x TIG Welding Eqpt, and 1 x Spot Welding Eqpt.
SMEA is also equipped with a metal-to-metal bonding facility. It has a Clean Room for the application of bonding film, an Acid Pickling pre-bonding Line, an Enclosed Primer Spray Booth and two large Drying/Curing Ovens. Quality of bonds are being monitored through the destructive testing of test coupons and non-destructive testing of actual parts.
SMEA's Paint Spray Shop has water curtain booths, drying/curing ovens and a zinc phosphating line. Spraying is done under strict observance of ambient temperature and humidity. Paint thicknesses are being measured and plotted on SPC charts, and paint adhesion and hardness closely monitored.
The Heat Treatment Shop is equipped with 4 x Fluidized Bed Furnaces, 1 x Drop Bottom Air Furnace, 1 x Air Circulation Furnace and 1 x Induction Hardening System. An additional Drop Bottom Furnace is being procured. All these furnaces are being strictly maintained on a daily, weekly, monthly and quarterly basis in accordance with the various customer specifications.
The Surface Treatment Shop is approved to undertake Chromic Acid Anodising, Sulphuric Acid Anodising, Alochroming, Hard Chrome Plating, Manganese Phosphating, Chemical Milling, Shot Peening and Gift Blasting. All process solutions are strictly maintained by the SMEA Chemistry Laboratory. Other surface treatment processes such as cadmium plating and electroless nickel are being done at AIROD's Electroplating Facility.
SMEA Laboratories are aquipped with approved facilities such as the CNC CMM (2mm x 1m x 0.7m), Hardness Testers (Rockwell, Vickers and Brinnell), a 10-Ton Universal Tensile Testing Machine, a Humidity Chamber, A Clean Room (for the CMM and Calibration Activities), facility for Microstructural Examination and facility for Chemical Testing & Analysis. The Metallurgy Laboratory is also equipped with two MPI machines and two bond testers. An FPI line will be installed soon.
