MACHINES A TRONCONNER LES BARRES

摘要

A machine for cutting workpieces such as castings or metal barstock is described wherein a pair of cutting wheels are controllably fed into the barstock to sever the end thereof with a single pass. The cutting wheels, which operate in a common plane, are located with their axes offset and their perimeter edges are located on a common straight cutting path. A lateral control to automatically maintain the cutting wheels on the path even though their diameters are worn down by the cutting operation and a vertical control to preserve the offset between the axes are described.
