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.
