From routine grinding wheel shaping or sizing to emergency shaping or sizing projects, Mach-B can do that Mach-B Grinding Wheel Shaping and Resizing, a division of Goodson Shop Supplies, specializes in modifying abrasive grinding wheels set up shop in Winona, MN in 2004. Since that time, we have expanded our staff and added a CNC machine to accommodate more wheels and provide more versatility to our offerings. In 2020, Mach-B, along with parent-company, Goodson Shop Supplies, became an Employee-owned company. What does this mean for you? It means every employee-owner has a stake in the success of our customers because our success depends on your success. We stand ready to help you in whatever ways we can. When an unexpected event happens such as a supplier's shortfall or a shop accident that compromises your grinding wheels, you can turn to Mach-B to have a new wheel on your shop floor in just a couple of days.
