Breaking speed barriers in laser cutting

February 14, 2007

By: ,

A real breakthrough in high-speed laser cutting occurred in 2005. Two additional parallel kinematic drive axes were placed near the point where the laser exits the head, creating a laser cutting machine with one dynamic and light cutting torch capable of independent movement along two axes but working in precise synchronicity with the machine's more sweeping movement of the laser head. This new approach opened up new frontiers and much higher limits in processing speed.

Detroit's reality check

February 13, 2007

By:

As the Big Three try to return to profitability, most of their suppliers, many with a negative cash flow, are starting to crack under the pressure. Declining OEM unit volume and mix issues, pricing pressures, and high sustained raw material costs continue to constrain cash flows and limit balance sheet improvements that, in some cases suffered significant deterioration in 2006.

Safeguarding tube benders with laser scanners

February 13, 2007

By:

Tube benders require safeguarding around the perimeter of the machine and area in front of the machine, where the tube is bent, and in the back where the tube is fed. Laser scanning devices offers several advantageous features. Because laser scanning is a noncontact method, it minimizes interference with the machine operation, and because the scanner mounts at the foot of the machine and out of the way of the tube bending action, it allows full access to the work area.
