Port Machining No Problem

In racing, you can’t have too much horsepower, and one of the ways to increase it is to “let the engine breathe” by enlarging the intake and exhaust ports of the engine. Read on to see how Karlo Apro, product manager – multiaxis, explains how the porting process has changed.

In the Pursuit of 5-Axis Precision

To speak of the aerospace industry is to imply “precision”: One instantly thinks of beautifully engineered airliners, awe-inspiring jet fighters, and rockets to the moon and beyond. Aircrafts are manifestations of imaginative engineering and precise manufacturing execution. In a mere 100 years, airframes have evolved from a few tubes held together by piano wires to complex engineering marvels made of space age materials.

Gear-driven Machining

Growing markets such as wind energy, hydroelectric power and mining are driving the popularity of cutting low to moderate volumes of spiral bevel gears on 5-axis machining centers, as opposed to dedicated gear generating equipment. In addition to those markets, shops manufacturing gear cases and doing prototype work also are showing interest in 5-axis machines for spiral bevel gear cutting.

The Impeller – Quintessential of 5-axis Machining

Few 5-axis machine users ever cut an impeller. Yet impellers are repeatedly used as examples by CAD/CAM software vendors and machine tool builders. There is a practical reason for this. Impellers have challenging shapes that ably demonstrate 5-axis capabilities.
