Rossini Software allows a communication and data management with the customer’s management data system according to the specs of INDUSTRY 4.0 (Italy). PRIMA PLC makes lathing and precision grinding of the external surface, steps, roller/sleeve facing and the automatic wheel adjustment cycle an easy task. The grinding wheels and lathing tool movement on two independent axis and the horizontal moving function is controlled through encoders applied on motors with specific automatic handling software. The PLC allows a seamless work flow operation on the roller/sleeve and has a memory function to recall set parameters for repeat jobs (series production). Standard grinding profiles: Parallel profile (standard), tapered profile, trapezoidal profile, crowned (cambered) surface convex or concave (with specific grinding wheels shapes), stepped shaping, edge trimming.
