The DMG HSC 55 Linear is a used machining center — sometimes referred to as a CNC machining center or milling machining center — dating from 2012. Machining centers of this type are precision multi-axis machine tools designed for high-speed cutting, milling, drilling, and contouring of complex workpieces, and are widely used in aerospace, automotive, die-and-mould, and precision engineering industries. DMG, part of the DMG Mori group, is one of the world's leading manufacturers of cutting machine tools, supplying high-performance turning, milling, and multi-axis machining equipment to demanding industrial sectors globally.
This machine is configured as a five-axis unit, enabling simultaneous multi-axis movement for the machining of complex geometries in a single setup. Control is handled by a Heidenhain iTNC 530, a well-regarded conversational CNC system known for its precision contouring capability and suitability for five-axis work. The Y-axis transversal travel is 650 mm, and the A-axis offers a swivel range of −10° to +110°, providing considerable angular flexibility for tilted-surface and undercut machining.
The spindle covers a speed range from 2 rpm up to 28,000 rpm, making it well suited to high-speed cutting applications across a broad range of materials. Spindle power is rated at 38 kW (S1) / 28 kW (S6), and the toolholder interface is HSK-A63, a taper widely adopted in high-speed machining for its rigidity and repeat accuracy. Maximum tool diameter is 80 mm, maximum tool length is 250 mm, and maximum tool weight is 6 kg.
The integrated tool magazine accommodates 120 tools, supporting extended unmanned or lights-out machining runs without manual intervention. Electrical supply requirements are 400 V / 50 Hz / 3-phase, with a total power demand of 70 kVA. The machine weighs approximately 9,500 kg, reflecting the substantial cast structure typical of high-speed precision machining centers of this class.
