The insert seats of the DTM milling body can be adjusted in the axial direction via an adjusting screw. Every ten-degree rotation moves the insert seat by 0.01 mm. This means that the axial run-out of the individual cutting edges can be adjusted with micrometre precision. The internal coolant supply ensures targeted cooling of the contact zone and enables efficient chip removal. The low mass of the aluminium body protects the spindle and reduces energy consumption compared with steel bodies. Horn offers a fine balancing option for the body in order to achieve high cutting speeds of up to 5,000 m/min and ensure that the tool runs quietly.
The range of applications for brilliant-finish milling is huge. In the tool and mould making industry in particular, the method saves polishing while also increasing the quality of the surface and its flatness. It is therefore used in applications where the surface of the mould has a direct influence on the parts being produced. This includes clear, transparent plastics or valve plate sealing surfaces, for example. MCD-tipped ball nose end mills are used to produce PET blow moulds or chocolate moulds. In addition to brilliant-finish milling, Horn’s tool portfolio also includes solutions for brilliant-finish turning with MCD tools.
