Goodway GS-2000 Series CNC turning centres are modular, so customers can specify a turning centre that precisely matches their needs in terms of functionality, performance and return on their investment.
Major structural components have been combined into one solid platform, giving a low centre of gravity on the 30º slant bed design that provides a rigid foundation for the headstock, turret and sub-spindle. Finite Element Methods (FEM) have been used for optimal positioning of the reinforcing ribs, which are cast directly into the FC35-Meehanite one-piece cast iron bed structure. This allows the GS-2000 Series machines to perform heavy-duty turning while maintaining high precision accuracy for extended period. Extra wide hardened and ground box ways are directly formed onto the machine bed during the casting process. They are precision machined and widely spaced to provide the rigidity needed for interrupted turning applications.
The GS-2600YS, with a Hydrafeed barfeed, provides the perfect example of the advantages of modularity. As a fully specified turning centre, it is equipped with a high precision 26 kW built-in spindle motor, providing 40 to 4,000 rpm with full C-axis control, while the 15 kW sub-spindle provides a speed range of 60 to 6,000 rpm. Both the X- and Z-axis rapids are 30 m/min and travels are 280 and 800 mm respectively. A 100 mm Y-axis (± 50 mm over the centreline) on the 12-station tooling turret allows milling, drilling and tapping operations to be carried out on even the most complex components.
