Engineering
Welcome to the virtual Engineering Department for the Winterthur Group. The following form will contain the necessary process, equipment & parametric data needed for one of our skilled engineers to assess your needs and determine which product(s) will best suit your objectives and business goals. Winterthur Swiss Precision Grinding Wheels ™ will provide you with a clear performance advantage. Many times, by migration to a premium abrasive product, a customer will see more finished parts between dress cycles, better material removal rates, better surface finishes, increased feed rates and through-puts and a reduction in down or set-up time which ultimately reduces cycle times and significantly lowers operating costs. Please complete the form below including as much information as possible. Please keep in mind that the more complete the information, the better our chances at getting it right the first time.
