Established in 1962, Doosan Heavy Industries & Construction Co. Ltd. (www.doosanheavy.com)is one of the major companies in South Korea, playing a major role in the development of Korea’s national economy by supplying industrial facilities to domestic and overseas markets. Doosan is also building a brighter and happier future for people with its power plant technology implemented in Sipat - India, Tennessee - USA, Shuaibah - Saudi Arabia, Ras Laffan - Qatar, and Qinshan - China.
Doosan has so far built over 300 nuclear, thermal, combined cycle and hydro power plants and is currently building more than 60 power plants in Korea, USA, India, China and other countries. Doosan is fast becoming an EPC contractor as a result of continuous investments and R&D, while also developing wind power systems, fuel cells and environmentally friendly next-generation energy.
Doosan is one of the few companies in the world that has proprietary technologies for all the three desalination methods (which are MSF, MED and RO) and water/wastewater treatment. This company also supplies casting and forging products, which are the basic materials for power and desalination plants.
Doosan is one of the best companies in the world in SOC projects such as road, port, airport and subway construction as well as in the construction of industrial plants.
The Horizontal Boring and Milling Machine model BP 160 CNC, produced for Doosan Heavy Industries & Construction Co., Ltd. is intended for completely machining the pallets of the water turbines for nuclear power stations. The intricacy of these components requires machining on 5 axes simultaneously, as well as very high machining accuracy and productivity.
Structurally, BP 160 CNC is a floor type boring and milling machine with horizontal spindle.
Its main technical features are:
Boring spindle diameter mm 160
Milling spindle speed range (stepless) rpm 4 -2500
Main motor rated power KW 100
Column travel (X axis) mm 10,000
Spindle head travel (Y axis) mm 5,000
Ram travel (Z axis) mm 1,000
Boring spindle travel (W axis) mm 1,000
Feed range: X, Y mm/min 15,000
Z, W mm/min 6,000
Besides the outstanding features of the basic machine, the following special attachments enhance and diversify the machining capabilities:
Rotary table of 2500 x 2500 mm and 40 tons load capacity
CNC Facing head of 630 mm facing diameter
CNC Universal milling head with two CNC axes
Floor tables of 6,000 x 2,000 mm surface
Automatic tool changer – 40 tools
Chip conveyor.
By March 2010, after the machine reaches DOOSAN facilities, it will be commissioned and tested by the specialists of World Machinery Works.
