around the principal flow to concentrate it onto the kerf, expelling molten material more efficiently. The Highspeed Eco process relies on a patented nozzle fitted with a sleeve that forces the gas directly into the kerf, ensuring that little or no gas flows off to the side (see diagram). While this moving sleeve glides across the material during fusion cutting, the nozzle remains 0.06 in. from the sheet surface. This ensures that the nozzle can effortlessly withstand any spatter generated during piercing, which accelerates piercing and minimizes the risk of damage.
Highspeed Eco and Highspeed can be used on machines in the TruLaser Series 5000 equipped with an 8-kw solid-state laser, with availability soon for use with 6-kw solid-state lasers. The Highspeed process is featured on machines in the TruLaser Series 3000 fitted with a 6-kw solid-state laser. In addition, many existing machines can be retrofitted with these processes.

pallet-rack-storage manufacturers in North America, produces more than 100 million lb. of pallet racks, high-density storage racks and specialised rack systems each year.
Highspeed and Highspeed Eco can be used for fusion cutting of mild-steel and stainless-steel sheets in thicknesses of at least 0.16 in. Additionally, just one nozzle is needed for the entire material- thickness range, which shortens setup time and reduces the likelihood of setup errors. Cut edges reportedly exhibit low surface roughness and a high-quality, consistent look.
Coolant-Filtration System Saves Rollformer $20,000 Annually
To produce these racks, the company, at its Pennsylvania warehouse, employs rollforming to continuously bend steel strip into desired cross-sections. The roll- forming machinery requires the use of a chemical coolant to facilitate the process, ensuring a smooth and more efficient operation. As a result of rollforming, fine metal particles, 0 to 50 microns in size, create contamination in the coolant.
Eclipse Magnetics has provided pal- let-rack-storage manufacturer Ridg-U-Rak with an Auto-Mag Skid magnetic filtration system, saving the company $20,000 annually. Ridg-U-Rak, one of the largest
Prior to installation of the Auto-Mag Skid system, as the coolant returned to the open fluid tank, particulate would build up in the tank, requiring regular vacuuming to remove it. Ridg-U-Rak employ- ees had to remove the contamination and clean the tank, a $3000 job, every three months. The contamination also damaged the rollforming tooling, as the
