Innovative vises, magnetic clamping, cut costs, setup times

WHEN YOU WORK in the fiercely competitive job shop market, anything you can do to improve productivity and cut machining costs will help you secure orders—and your business. That’s why Tony De Simone, founder of DSA Precision Machining Inc., Bolton, ON, and son Chris, plant manager, decided to invest in innovative workholding systems—Lang vises and jaws and SPD electro-permanent magnetic chucks—that have helped them secure new orders for business, reduce part setup times and increase machining productivity. Tony De Simone formed DSA Precision Machining in 1976. After years of working in job shops, including Massey Ferguson, York Gear (now Spar Aerospace) and Husky Injection Molding Systems, he decided to set up his own machine shop. Since then, De Simone and son Chris, who joined the company in the 1990s after graduating from mechanical engineering/CNC programming from Humber College,


DSA PRECISION MACHINING’S workholding investments include the Lang Makro-Grip vises and Quick-Point zero clamping system, and SPD electro-permanent magnetic chucks. The products were all purchased from workholding product distributor, Machine Tool Solutions Ltd., Brampton, ON. The Lang Makro-Grip centre vise is well-suited to five axis movement because it holds a part securely during machining in all five axes. The secret to the vise’s effectiveness lies in the holding teeth contour of the jaw and in Lang’s Quick-Point zero point clamping system—base metal plates available in rectangular, square and round shapes—that holds the vise in place. “We can interchange difference vises on the plate because the Lang system comes with probes that are inserted onto the plate and lock the vises into the programmed position,” explains Chris De Simone. He adds that he likes the flexibility and the time-saving feature of the workholding system. In the past, DSA would use one vise


Editorial featuring LANG Workholding at Koss Aerospace

When founder Drago Cajic started Koss Aerospace in 1975, aerospace component manufacturing relied heavily on the skill and knowledge of the machinist. Thirty-six years later, that enhanced knowledge continues to be the core of Koss’s business. Koss, located in Mississauga, Ontario is still one of the aerospace industry’s leading anufacturers of machined components and sub-assemblies. Koss Aerospace is a fully integrated, Lean Manufacturing operation, utilizing the latest in machine tool technology and CAD/CAM software. To maintain their competitive edge, Koss Aerospace has also achieved AS/EN/JISQ 9001 Rev B and ISO 9001:2008 status; as well as providing NADCAP Chemical Processing, Heat Treatment, and NDT & Surface Enhancement support services.
The Koss facility was designed and built in 2006 for maximum workflow and efficiency. “From the beginning”, says Cajic. “Everything in our building was designed for efficiency and flexibility. The electrical and all other services have been installed to permit us to change the plant layout and workflow to suit the needs of each contract. As part of our efficient workflow and flexibility, Koss employs an advance ERP system that allows further control on all projects in terms of cost and status, providing additional visibility of project development.
Koss Aerospace’s client base is the who’s who in aerospace manufacturing, including Bombardier, Goodrich, Boeing, Spirit Aerospace and the U.S. Government (direct). As a supplier to the major OEM’s and their sub-contractors, Koss Aerospace has extensive manufacturing expertise, offering a full array of integration processes, including manufacturing, processing and assembly kitting. This enables Koss to be vertically integrated from manufacturing to processing, to complete assembly.
