Palletization system boosts productivity: Supply Chain & Logistics

To effectively serve boat building customers and remain competitive, Roswell U.S. LLC must design products, produce them and bring them to market as quickly as possible. At its Rockledge, Florida, facility, the company accomplishes that with flexible, productive machine tools.

CEO and Chairman Robert Oswell started the company, which does business as Roswell Marine, in Canada in 1998. He opened the Florida facility, which employs 48 people, in 2007. The company’s line of more than 400 products includes towers and accessories for wakeboard and water ski boats, swiveling board racks, Bimini tops and marine audio systems.

All manufacturing operations always have been performed in-house to better control product quality.

“From napkin sketch to customer-ready product, we control all aspects of the product life cycle,” Oswell said. “Product and manufacturing flow is determined according to current industry best practices and all internal past captured data. We look for the best equipment and software that will keep us efficient and competitive.”

When the Florida facility needed additional equipment to increase its machining capabilities, the company compared offerings and selected machine tools from Mazak Corp., Florence, Kentucky. Roswell Marine’s most recent Mazaks include an HCN-8800 horizontal machining center and two HCN-5000 HMCs. The HCN-8800 has a built-in two-pallet changer. The HCN-5000s have 120-tool changers and are part of Mazak’s two-tiered 24-pallet Palletech automation system.

The modular palletized manufacturing system further boosts productivity of many of the company’s horizontal, five-axis and multitask machines. System configurations include one-, two- or three-pallet stockers; tilting load stations; centering load stations; part wash stations; and material storage. Overall, a system can accommodate up to 16 Mazak machines, six to 240 pallets and as many as eight loading stations for unattended operation.

John Runske, program implementation manager at Roswell Marine, said the 800.1 mm (31.5″) pallet size and maximum workpiece height of 1,450.086 mm (57.09″) of the HCN-8800 accommodate large parts, such as cast aluminum billets that may initially weigh 317.5 kg (700 lbs.) and end up at 31.8 kg (70 lbs.) after machining.
