Machining Capabilities
High-tech machines offer superior quality

The significant investment into state-of-the-art, sophisticated machinery sets AER apart from all other remanufacturing companies.

With Computer Numerically Controlled (CNC) Machining Centers, AER easily and consistently surpasses the most demanding requirements.

Horizontal CNC Machining Centers

Five-Axis Machining Center

•	Turn boring accuracy to +0.05 mm with over 1.33 C
•	Precision liner glass scales in X, Y and Z axes

CNC machining centers enable AER to:

•	Consistently achieve highest accuracy measurements
•	Reduce cycle times by 55%
•	Provide same-day entire engine assembly replacement
•	Maintain well-stocked inventory of engines

Robotics

This computer-controlled process buffs and cleans the intake and exhaust manifold surfaces on cylinder heads.

The use of robotics provides:

•	Tighter tolerances
•	Dependable repeatability
•	Higher cyclic rates

Direct Current (DC) Torquing

Torque-to-yield fasteners require DC-drive, controlled fastening systems to correctly and consistently tighten bolts to precise specifications and tolerance ranges.

The electrically controlled torque guns and fastening tools are used in three critical areas:

•	Cylinder head bolts
•	Main bolts
•	Connecting rod bolts

CNC Crankshaft Grinder

AER is the only remanufacturer and supplier in the United States with a CNC Crank Grinder. This machine offers cutting-edge technology for the fully automatic production process. Typically found only in OEM plants, the capabilities of the new generation CNC Crankshaft Grinder easily exceed current requirements.

The CNC Crankshaft Grinder is designed for complete grinding of crankshafts in one chucking. This technology offers:

•	Stabilized dimensional accuracy and surface quality
•	Tighter tolerances
•	Ability to achieve and consistently maintain highest product quality

CNC honing machine

AER continually looks for ways to improve its products and processes, and it invests in the newest and best technology available. The recently acquired CNC honing machine, which will be installed and operational in 2003, will allow AER to easily surpass all current finish requirements for the remanufacture of engine block cylinder bores.
