A layer of flexible abrasive flaps lies flat against the sheet metal surface. As the grinding wheel is fed, the flaps are pressed elastically into the edge. This results in a more even distribution of material removal compared to a pulling grinding process. The resulting cross-sectional image shows a rounded shape reminiscent of a trumpet, hence the name \"trumpet profile\".\r\n  <\/p>\r\n\r\n  <div class=\"boeck-info-box\">\r\n    <h3>Factors influencing the trumpet profile<\/h3>\r\n    <ul>\r\n      <li>tool assembly<\/li>\r\n      <li>infeed<\/li>\r\n      <li>contact pressure<\/li>\r\n      <li>speed<\/li>\r\n      <li>feed rate<\/li>\r\n    <\/ul>\r\n  <\/div>\r\n\r\n  <h2>Effects on edge quality<\/h2>\r\n\r\n  <p>\r\n    A reproducible Trumpet profile creates a smooth transition between surface and edge. The more surface-oriented material removal results in a softly tapered radius geometry with a homogeneous edge appearance.\r\n\r\n  <\/p>\r\n\r\n  <div class=\"boeck-info-box\">\r\n    <h3>Potential

the edge rounding process step, deburring discs and deburring blocks are used to remove primary and secondary burrs and to create a reproducible radius-like transition between surface and edge.\r\n  <\/p>\r\n\r\n  <p>\r\n   The pressing action typically results in a Trumpet profile with a wide transition to the surface.\r\n  <\/p>\r\n\r\n  <div class=\"boeck-process-box\">\r\n    <span>Related

created?<\/h3>\r\n    <p>\r\n     A Trumpet profile is created when rounding edges with deburring discs or deburring blocks, when flexible abrasive flaps lie flat on the surface and are pressed into
