DOOSAN VM 960L CNC machining center

DOOSAN VM 960L CNC machining center was built in 2016 in South Korea by Doosan Machine Tools. The machine on offer is an excellent choice for both roughing and finishing machining of workpieces with a maximum weight of 4500 kg. It is distinguished by a number of state-of-the-art technical solutions, which, combined with extensive equipment, guarantee excellent repeatability of the manufactured parts over many years of intensive operation.

All machining processes, i.e. drilling, threading and milling, are performed by means of a reliable spindle and cutting tools taken from a 40-position magazine. The very accurately balanced spindle ensures vibration-free operation at all speeds. Its taper is cleaned continuously with compressed air to protect it from chips and coolant. The entire workspace, in turn, has been fully maximised to ensure freedom of operation.

The offer also includes an extensive range of equipment, consisting of, among others, a HEIDENHAIN control system, a set of measuring probes and a large amount of tooling. The VM 960L CNC vertical machining center weighs 21000 kg.
