High-precision plasma system automates Chromalox’s cutting, beveling processes
- By Eric Lundin
- Dec 17, 2014
- Cutting and Weld Prep
- Article
Chromalox, a manufacturer of industrial heating systems, relied on skilled workers do quite a few manual processes, especially cutting and beveling. As the supply of people with this skill slowly dried up, the company realized that it would need to invest in an automated system. It chose an Ultra-Cut 400 XT plasma power supply from Thermal Dynamics (Victor) and coupled it to a 6-axis CNC pipe-handling system from Watts Specialties Inc.

Improving flying cutoff operations, mill productivity
- By Daniel Johns
- Dec 16, 2014
- Tube and Pipe Production
- Article
Tube and pipe production is a capital-intensive process, but paying close attention to the efficiency of some of the lowest-cost items, specifically the consumables, can yield big benefits in productivity. At the cutoff, proper blade choice and optimizing the cutting depth are important first steps, but it’s also necessary to diagnose saw problems and—most important of all—develop a blade replacement strategy that minimizes mill downtime.
