More from Steve Redick on the 2-11 Alarm fire in Chicago, 2-11-20
Tuesday night around 12:45 AM, a fire broke out at Cermak and Michigan. The scene involved a dry cleaners and what appeared to be a yoga studio. By the time I arrived, the bow string truss had already fully collapsed. The fire didn’t seem to spread to either of the adjacent buildings. Those familiar with the area might recognize this as part of the old “Automobile Row†district, which has historical significance in Chicago’s development.

As I stood by the scene, it was clear that this wasn't just another call—it was a reminder of how quickly things can go wrong. The building structure was compromised, and the fact that the fire didn’t spread to the neighboring buildings was a small relief. It's always interesting to see how these older parts of the city hold up under pressure. The photos show the intensity of the response and the dedication of the crews on the ground. This is just one of many stories from the front lines, and I'll keep sharing more as they come in.
The characteristic of a three-axis CNC machining center is that it can only machine one surface at a time, which is suitable for machining disc type parts.
A three-axis CNC machining center typically refers to three axes that move linearly in different directions, working together to control the movement of cutting tools in three-dimensional space, achieving various machining operations such as planar cutting, drilling, and milling. However, three-axis Machining Centers can only process one surface at a time, which becomes a limitation for parts that require hole or groove machining on multiple surfaces. Therefore, three-axis machining centers are more suitable for handling some simple part machining tasks, such as the manufacturing of planar structural parts or linear grooves.
Although three-axis machining centers perform well in machining simple parts, their limitations become apparent for more complex machining requirements, such as scenarios that require fine machining on different surfaces of the workpiece. That's why when entering more advanced machining technologies, such as four axis and five axis machining centers, they become more preferred. Four axis and five axis machining centers have achieved simultaneous machining of multiple surfaces of workpieces by adding rotation axes, greatly improving machining efficiency and accuracy.
