The DIMF Show (Doosan International Machine Tool Fair) proved to be an inspiring event, with 5,700 Doosan dealers, distributors, academics and officials, and more than 800 international visitors attending. It was memorable for a number of reasons, but it’s worthwhile stating from the outset that this year’s show was particularly impressive with some 80 Doosan machines in total being exhibited.
This number comprised 26 new models from Doosan’s 5-axis machining centre, large-capacity lathe, big horizontal and horizontal boring machine and multi-tasking, multi-axis mill-turn centre ranges. In addition to showcasing these new machines, DIMF 2017 was also the venue where Doosan’s latest Industry 4.0, Smart Factory and automation solutions were exhibited.
Doosan is one of the largest global manufacturers of CNC machine tools and the sheer size, scope and scale of this year’s show reinforced the company’s market-leading position.
Although DIMF took place at Doosan’s South Korean Namsan and Sungju facilities, the event is definitely not a parochial one as many of the new and upgraded machines and technologies on view will soon become available to manufacturers across the world via Doosan’s subsidiaries and its global network of distributors and dealers.
Indeed, one of the major reasons why we at Mills CNC attended the show was to identify the new and upgraded Doosan machines that will be promoted and stocked at our Technology Campus in Leamington in the near future.
5-axis highlights
DIMF provided the ideal venue for Doosan to showcase two latest additions to its already extensive 5-axis machine tool line-up. These machines – the DVF 5000 and DVF 8000 – are available with a choice of controls (Fanuc, Siemens and Heidenhain) and provide manufacturers with full 5-axis simultaneous machining capability.
Both machines are equipped with a 12,000rpm directly-coupled spindle (18,000rpm built-in spindle option) and, with the DVF 5000, feature a 500mm diameter rotary table (630mm option) or, in the case of the DVF 8000, a direct-drive 800mm diameter rotary table.
The machines are automation-ready, and can be supplied with a range of different automatic pallet change systems that increase their productivity potential.
Horizontal machining centres
Doosan horizontal machining centres are recognised for their performance and productivity-enhancing features. At this year’s DIMF show a number of horizontal machining centres were exhibited including the launch of two new high-speed, high-accuracy machines; the NHP 4000 and NHP 5000.
Both machines feature a rigid design and build, and are equipped with powerful high-torque spindles (up to 37kW/20,000rpm/308Nm). The machines provide users with 1g acceleration/deceleration and 60m/minute rapid rates on their X-,Y- and Z-axes.
Horizontal fixed head lathes
No DIMF show would be complete without specific attention being focused on Doosan’s new Lynx and Puma lathe ranges. New additions and upgrades to the Lynx range of lathes included the introduction of 8-inch chuck models (Lynx 2100Y/LY/LSY) with Y-axis capability, and the 10-inch chuck/81mm bar capacity Lynx 2100LC; all available with Fanuc or Siemens controls.
New Puma lathes were also a centre of attraction and amongst the many highlights were the new 10-inch chuck Puma 2600 (Y-axis) Mark II machines. The new Puma 2600Y/LY/SY/LSY lathes feature sophisticated thermal compensation sensor technology which, in combination with their rigid design and improved spindle bearing structure, deliver guaranteed accuracies, even during continuous use.
DIMF also saw the unveiling of a new large-capacity Puma lathe - the Puma 1000M. This machine can be specified with up to a 40-inch chuck and has a maximum turning diameter of 1,000mm and a maximum turning length of 2,040mm. With its powerful, high torque spindle and rigid design, the Puma 1000M is Doosan’s largest horizontal lathe and is ideal for heavy-duty machining operations.
Multi-axis machines
Multi-axis machines were out in force at DIMF with pride of place reserved for a new range of SMX mill-turn machines equipped with lower turrets. The SMX range, already available in the UK, has now been joined by two new models – the 10-inch chuck SMX 2600ST and the 12-inch chuck SMX 3100ST.
These new machines feature Doosan’s orthogonally-designed (300mm) Y-axis equipped with 12 station lower turrets for improved manufacturing flexibility and productivity. The last new Doosan machines worthy of special mention launched at DIMF were the Puma TW2100 GL – a 8-inch chuck (6-inch chuck option) twin-spindle horizontal turning centre with an integrated gantry loader, and the large-capacity Puma V8300M (up to 24-inch chuck) with its uniquely-configured and versatile Capto C6 ATC.”
Summary
DIMF 2017 was a truly impressive event. Although the show is over, its impact, due to the many new technologies introduced, will be felt around the world for months and years to come.
Mills will be showcasing a number of the machines launched at DIMF at its ‘Strokes of Genius…LIVE’ open house taking place at its campus facility from 18-19 October 2017, and from its stand at the MACH 2018 show.”
