[New product] Doosan GVX 2430

202201030356035030

The GVX 2430 achieve the highest productivity with its high acceleration/deceleration spindles and its high acceleration/deceleration feed axis.
The GVX 2430 boasts a rapid traverse speed (X/Y/Z) of 60 / 60 / 30 m/min, and a dramatically reduced non-cutting time due to the improved acceleration/deceleration performance of the shaft system. All axes are lubricated with eco-friendly grease as a standard feature. The GVX 2430 has a maximum spindle speed of 12000 r/min, maximum spindle motor output of 18.5kW, and direct-coupled spindle motor torque of 95 Nžm, while its tool taper is ISO #40. Its productivity in machining medium-size and large parts has also been improved by equipping it with a direct-connected spindle as a standard feature. In particular, the adoption of a cooling system of gas temperature synchronization method ensures reliable control of the heat generated by the bearings and motors, while the spindle cooling system minimizes thermal displacement. Non-cutting time has been reduced significantly thanks to its rapid tool-change time of just 1.3 seconds and chip-to-chip time of 9.7 seconds, while it’s highly reliable tool magazine can load up to 24 standard tools.
 
Design optimized for lightweight material machining
The GVX 2430 has a gantry-type structure that is advantageous for machining large workpieces, and has the following specifications: X-axis 3000 mm / Y-axis 2000 mm / Z-axis 450 mm (option 600mm) travel distance, and an effective passage width of 2400 mm. It has a maximum machining area with a table size of 3000 mm * 2000 mm and a table load capacity of 1000 kg. In addition, it can maintain stable machining for a long time as its structure is optimized not only for the machining of large workpieces but also for the lightweight machining of aluminum parts. The adoption of an aluminum table as a standard feature has minimized the difference in the thermal displacement characteristics between the aluminum material and the table. The GVX 2430 is also equipped with a screw conveyor on its left and right sides to facilitate chip processing, while the adoption of a half cover as a standard feature prevents the scattering of chips and coolant to keep the working environment clean. It is also fitted with a grease lubrication device, making an oil skimmer unnecessary, and reducing the cost of maintaining integrity by about 60% compared to oil lubrication.

Doosan PUMA VTR2025, a large ram-type vertical turning center

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.
