Doosan Machine Tools (CEO Jae-seop Kim, www.doosanmachinetools.com) has just launched the VCF 5500L turning center in a bid to expand its VCF 5500 series in addition to the latest VCF 5500UL. The VCF 5500L is optimized for the processing of not only small and medium-sized automobile parts but also long and narrow workpieces. It is capable of performing high-precision operations for prolonged periods thanks to the adoption of a direct-coupled spindle as a standard feature, thus ensuring a quieter work environment despite its optimum cutting performance.  Furthermore, the new machining center’s table-fixed, moving-column structure has further increased operational convenience and boosted productivity with the optional center partition. The adoption of various applications customized for diverse processing jobs maximizes productivity even in a multipurpose processing environment. 

Outstanding Machining Precision and a Quiet Working Environment
Initially developed to meet the need for machining long and narrow workpieces for the small and medium-sized automobile parts market, the VCF 5500L offers increased rigidity due to the application of roller LM guideways to all axes, while the X axis is equipped with a linear scale as a standard feature to optimize positioning accuracy even during prolonged periods of operation. The directly-coupled spindle with a maximum speed of 12000 r/min guarantees precise machining while generating the least amount of vibration and noise thanks to its maximum spindle motor torque of 117.8N·m and maximum spindle motor power of 18.5kW.

30 Tool Magazine, ATC Boosts Productivity 
The center comes equipped with a high-quality ATC to bolster the reliability of tool change, while machining productivity has been boosted significantly by the adoption of a magazine with a capacity of up to 30 tools. For customers who need tools with a large diameter or length, a pickup magazine capable of accommodating diverse machining requirements is offered as an optional feature.

Improved Chip Disposal and Operational Convenience
Thanks to its smaller exposed area, the bed structure, with a steep inclination of 360, is more effective in preventing the buildup of chips typically generated during the processing of aluminum pieces. The improved performance of the flushing coolant and coolant filter, along with the bed structure, combine to create a synergistic effect for chip disposal. Finally, the operator's comfort and convenience has been enhanced with the adoption of an operation panel that moves horizontally and rotates by 180 degrees
