During EMO 2019, Doosan Machine Tools placed particular emphasis on hands-on experiences that allowed visitors to experience the actual application of multitasking technologies and automation solutions that are currently attracting keen attention in the industry, and the enhanced operator convenience provided by the latest cutting-edge machine tools. To meet visitors’ needs, the company displayed their full product line-up ranging from their global bestsellers to high-end sophisticated machine tools to 5-axis multitasking tools to large-size machine tools.
Most notably, Doosan featured their full line-up of 5-axis machining centers, including the DVF 5000, DVF 6500 and DVF 8000T, in order to emphasise their competitiveness in multitasking solutions in the industry.
To highlight Doosan’s competitiveness in new and emerging manufacturing technologies, they also introduced the company’s own NC platform, their advanced automation and upgraded processing features, and their unique ‘iDOO CONTROL’ solutions designed for real-time monitoring, cost reduction, and productivity improvement.
Doosan DVF 6500/8000/8000T
Doosan Machine Tools has launched the DVF6500/8000/8000T with a Ø650/800mm rotary table for machining workpieces of complex shapes with a standard 12 000rpm (option: 18000rpm)/min high-speed built-in spindle, and initiated full-fledged sales of the new machining center.
The DVF 6500/8000/8000T machining center requires an even smaller installation space than previous models and features a grease lubrication system. The machine tool is designed to allow easy access to the operator in an effort to maximise user convenience. Notably, to enhance precision, the new machining center is equipped with a thermal compensation function for the spindles and overall structure, and spindle and ball screw cooling as standard features.
The tool magazine can hold up to 120 tools and is designed to allow various types of processing with a single setting. A tool length measurement device is also included for more precise processing. Furthermore, the new machining center is equipped with a multi-cover designed for automatic workpiece loading and unloading, thus enabling a crane to approach the centre of the pallets via the opening. The machine tool can also be linked to diverse pallet automation systems, leading to higher productivity and unmanned processing.
It also features an optimal solution for processing hard-to-cut workpieces that facilitates the discharge of chips via an improved coolant tank filter. Please contact your nearest Doosan Machine Tools dealership for further details about the DVF 6500/8000/8000T, Doosan Machine Tools’ new premium 5-axis machining center, which is optimised for the unmanned processing of hard-to-cut, complex workpieces, automation, improved access, and operational convenience.
Doosan Puma TT2100SYY/1300SYY
Now with upper and lower Y-axis turret added, this high-performance multifunctional horizontal turning center has allowed Doosan Machine Tools to expand its line-up of the Puma TT series, a high-performance process-intensive turning center that can automate all the workpiece input and output processes on one machine tool.
The Puma TT2100SYY/ TT2100SYYB/1300SYY/1300SYYB are high-capacity horizontal turning centers with the chuck size of 5/6/8/10 inches, respectively, equipped with bidirectional spindles and upper and lower turrets. They boast outstanding productivity as the first and second spindles can produce workpieces independently and the workpieces produced by each spindle can be discharged through an automated device. Actually, in a machining productivity test, the productivity of the Puma TT2100SYY equipped with a Y-axis applied to the upper and lower turrets, was up 20% compared to that of existing models.
Through the application of roller type LM guides to all its axes, the series has realised high-speed high-precision structure that enables customers to maximise their productivity while minimising thermal deformation through an optimised ball screw design to prevent thermal deformation. Most notably, through the application of Doosan Machine Tools’ technology and know-how, the belt spindle of the Puma TT series has secured the performance accuracy of the C-axis at the equivalent or higher level than that of a built-in spindle while securing high-torque specifications. Equipped with the same specifications and feed shafts, left and right spindles can divide cutting loads precisely at the ratio of 50:50, which ensures that the series can maximise its productivity. In addition, the turret, the pride of Doosan Machine Tools, equipped with a high-speed, high-rigidity servo motor, guarantees high productivity through precise tool replacement while doubling productivity through the simultaneous operation of upper and lower turrets.
Development of part catcher and part unloader for the Puma TT Series
The parts catcher and the parts unloader, the core automation devices of the Puma TT series, have improved remarkably in terms of rigidity and speed. The parts catcher that receives remnants or parts from left spindle has been improved structurally so that its operations cannot be disturbed by the lower turret in addition to the enhancement of its rigidity. The parts unloader that receives completed workpieces from the right spindle has been upgraded in its operational methods and specifications so that it can operate 33% faster than previous devices.
Improvements in user convenience
Equipped with a new ergonomic operation panel, the series has a screen developed by the company to facilitate an easy access to Doosan Easy Operation Package. The new panel also features a screen where operators can conveniently set or modify One Shot Cycle enabling one-stop operation of frequently used programmes such as parts feed and parts unloader. Through the application of an eco-friendly grease lubrication system instead of the existing oil-based lubrication system, the series has reduced the lubricant replacement cycle to once or twice a year, which enables customers to reduce maintenance costs significantly while keeping their working environment clean.
