For complete blade machining, the LX 021 combines the technology of Starrag and Bumotec. "The new Starrag LX 021 is designed for complete machining of blades up to 200 mm in a single clamping," said Günter Leitold, Product Manager for Automation at Rorschacherberg (Switzerland) based Starrag AG.
"Previously, there were hardly any machines for high precision complete machining on the market, because the blades required tended to have simple geometric shapes, which are normally made from forged or cast unmachined parts," said a company spokesperson. "However, there has been an upturn in demand for blades with more complex geometry made of demanding, difficult-to-cut materials with low ridigity and poor damping."
These challenges are now being addressed by a 5-axis machining center from Bumotec, which Starrag has adapted for the tough requirements of hard-to-work materials such as titanium and nickel based alloys. "The LX 021 rounds off the LX series, specially developed for high precision, efficient simultaneous 5-axis machining of turbine blades," said the spokesperson. "Blade producers can now enjoy solid and high precision machine technology that Bumotec originally developed for the clock and jewelery industry," said Leitold. According to the company, the machine is generally suitable for all kinds of turbine blades up to a finished length of 200 mm, such as the blades for gas or high pressure steam turbines. In 2015, the machine will also offer the option of attaching an automatic bar loader.
"One major benefit is the retaking unit with integrated revolver unit, which can hold up to three different active clamping elements," said Leitold. "This solution gives the user the ability to carry out machining on all sides, a key requirement for cutting in a single clamping," said the spokesperson. "However, the LX 021 cannot only be used as a stand-alone machine. Due to a feed station (automatic pallet changer), it can be integrated into a flexible machining system (FMS)."
