Upgraded version of the PUMA VTR2025, a large ram-type vertical turning center
The PUMA VTR 2025 is a large ram type of vertical turning center equipped with a 2000mm table and a maximum machining diameter of 2500mm. Productivity has been further improved with the adoption of a ram tool indexing system. The PUMA VTR2025 series consists of two main products, the PUMA VTR2025 and the PUMA VTR2025M.
Wide machining area
“The PUMA VTR2025 series has a wide column structure and boasts a full X-axis feed distance of -1000/+1600mm to left and right, the largest machining area in its class, as well as a Z-axis feed distance of 1400mm thanks to the adoption of a cross rail feed function. As the cross rail can move up to 1020mm, this series can machine large workpieces by optimizing the protrusion length of the ram, and enables strong, high-precision cutting as a 40-ton strong clamping device fixes the cross rail strongly. The series also offers a wider machining area (diameter: 2500mm diameter/height: 2000mm), and the inner and outer diameters can be machined and measured at the same time with a one-time setting. The new series guarantees productivity improvement as it can flexibly machine large workpieces of diverse shapes and sizes thanks to its wide machining area.
Strong and precise machining ability
“The series’ tool holder clamping force of 8000kgf guarantees strong machining, while the differentiated 90˚ ram indexing technology and 4-way multi-tool holder reduce tool change time by 75%, since a tool can be changed directly on the ram without having to access the ATC. The spindle, equipped with a large-capacity cooler and a complete thermally symmetrical structure, guarantees heat stability for a long time and ensures stable, precision machining.
User convenience
“The PUMA VTR2025 series is equipped with a multi-enclosed cover as a standard feature that improves the factory environment by preventing scattering of coolant and dust generated during machining. In particular, even though this series has a structure in which the machining area is completely closed at the top, the top bellows cover and front door can be opened automatically, making it easy to use a crane when loading and unloading a workpiece. In addition, the combination of an integrated bed and a dual chip conveyor, which secures a chip removal path to the left and right, ensures smooth chip removal. Doosan’s easy operation package improves production efficiency by providing various functions such as tool management, support for peripheral device setting and operation, and assistance, as well as user enhancing convenience.
