CNC turning milling centre HSTM XL series

The turning milling centre with horizontal work piece arrangement is partiucularly suited for machining turbine and compressor blades, blisks and/or radial compressors. The work area is inclined to the front at an angle of 45° to ensure optimal mass distribution, excellent loading options and impressive view of the machining layout. The machine meets the highest requirements for modern blade machining with regards to achievable accuracy and surface quality. The robustness and rigidity, together with integrated HSC support, ensure peak productivity. The compact design of the machine enables rapid and flexible erection at the customer without particular requirements regarding foundation characteristics.

Machine design

The machine consists of a single machine base on which all components are optimally positioned for the machining of horizontally clamped work pieces. The inclined construction of the roller-guided linear axes in the machine room guarantees excellent removal of chips. This can be additionally supported by the optional workspace flushing. Standard interfaces on the rotary axes and peripheral components are essential features of this machine, designed for peak productivity.

Slides carry both work piece spindles A and C on the front transverse X axis, the work piece is clamped between these spindles with suitable clamping devices. Both slides can be moved relative to one another to simplify loading/unloading. After the work piece is mounted, both work piece spindles are synchronized with regards to angle of rotation and linear movement by the NC so that no torsional deformation can act on the work piece during milling.

While the work piece is linearly positioned with X and rotationally with A/C, the tools is driven by the motor spindle in the linear axes Y and Z and the swiveling axis B. To change the tool, the motor spindle moves to the tool changing position and is swiveled through 90° so that the tool change can be implemented with a douple gripper.

Miling spindle

The extremely powerful motor milling spindle supplies a high performance potential for the machining of a wide range of work pieces, ranging from high-temperature resistant alloys, titanium and steel to aluminium.

All cooling and lubrication options are available for the milling process. All variants can be selected, ranging from classic wet machining, dry machining, high pressure cooling through with spindle and minimum quantity lubrication. The machine comes equipped as standard with two oil and emulsion mist separator devices.

Work piece spindles

Both work piece spindles, A-axis and C-axis are mounted on roller bearings as standard, and are driven directly by a torque motor. Hydrostatic bearings are also an option.

Measuring systems

Abolute scales are used in the linear axes X, Y- and Z and direct absolute encoders in the A and B axes, both from Heidenhain. These meet even the highest of requirements for 5-axes machining of work pieces, particulary turbine blades.

Feed drives

Maitenance-free frequenca-controlled three-phase motors with digital interfaces (control) for CNC control are used in all axes.

Lubrication

All ball screw spindles and guides are supplied wit grease at specific intervals. The B axis is also lubricated. The motor spindle is lubricated for life.

Saftey devices

All safety devices and operating points comply with specified EU directives. The machine is CE certified.

Setting up the machine

One-piece transportation (crane hook amchine) means that rapid installation and commissioning of the machine is possible and rapid availability for production start is guaranteed.
