摘要

Gas mixing at the cutting head, to practically eliminate purging between setups; a high-speed swirling assist gas that produces nearly perfectly square cut faces; and the ability to cut stainless steel with oxidation-free edges have led this fab shop into the next generation of plasma-arc cutting. Economical yet productive, fast yet accurate, and specialized yet diverse - all terms defining the new age in plasma-arc cutting ushered in by a high-definition plasma-arc cutting (PAC) machine that recently landed on the plant floor of Southwest & Associates, Inc. (SAI). Brought in late in 2015 to replace an aging PAC machine, the new machine, not surprisingly, offers technology enhancements that have SAI officials gloating over enriched capabilities. These include: 1. Cleaner cutting of stainless steel, to avoid secondary finishing operations; 2. The ability to cut 1.25-in.-thick stainless steel, work that the company previously outsourced; 3. Very accurate scribing of part features on cut parts, such as bend lines used by press-brake operators and punched-hole centerpoints; and 4. The ability to cut quickly and accurately without the need to use costly premixed gases, including cutting bolt holes free from edge taper.
