Turning operations are operations that rotate the workpiece as the primary method of moving metal against the cutting tool. Lathes are the principal machine tool used in turning; milling operations are operations in which the cutting tool rotates to bring cutting edges to bear against the workpiece. Milling machines are the principal machine tool used in milling.
Turn-mill machines integrate both technologies and operate on specific parts designed with perfect diameters and other geometries, typically flanges, pins and others.
HTF own NC turning and turn-mill machines operating daily on numerous parts on different programmes up to 900L x 160W x 500 mm diameter – 35 x 6 x 19 inches diameter.
