The common denominator across the energy sector, in machining terms, is the sheer size and weight of the components that need to be manufactured. In the oil and gas sector, it is drill pipes, casings, wellhead equipment and subsea valves, whilst the power generation sector is dominated by rotor shafts and discs, casings, impellers and generator shafts.
As a result, multi-tasking machines, which can reduce the numbers of operators, set-ups and the movement of large components around a machine shop, in turn improving the quality of the finished product, have been high on the sector’s priority list.
The INTEGREX e-H series of multi-tasking machines are ideal for this type of heavy, large diameter shaft type workpieces, because they are capable of completing all operations in a single set-up, including turning, milling, boring and drilling, without having to move the component to a different machine.
Crucially, even the smallest of the e-H series machines, namely the e-420H, has a large machining envelope with a maximum swing of 670mm, enabling large components to be cut. This envelope size and multi-tasking capability is complimented by a high power 4,000rpm main spindle and 12,000rpm milling spindle, which are capable of removing large amounts of metal whilst maintaining exceptional productivity.
At the top end of the e-H range is the INTEGREX e-800H, which has a large Y-axis stroke of 800mm which makes it ideal for extra-large part production. The machine has the power, torque and accuracy to achieve unbeatable metal removal capabilities when processing workpieces with load capacities of up to 15 tons. Critically, the machine is also equipped with a Long Boring Bar (LBB) which offers deep-hole capability and a rigid tool holder system, with four clamping units, for enhanced machining capacity and rigidity when machining large complex internal features that are common to many applications.
