Modig Machine Tool has introduced the MTX, a five-axis universal machining centre for medium to large aerospace components. It combines electrospindles with torque-motor-driven tilting heads on an A or B axis, handles parts up to 3,000 mm in diameter and 8,500 kg, and runs rapid moves at 60 m/min. Siemens, Fanuc and Heidenhain controls are available.
Three metres across, in one setup.
A five-axis universal machining centre for large aerospace parts.
The MTX combines electrospindles with torque-motor-driven tilting heads, available on either an A axis or a B axis. The envelope covers parts up to 3,000 mm in diameter and 1,950 mm in height, weighing as much as 8,500 kg.
Speed and motion
Rapid moves run to 60 m/min and acceleration to 7 m/s2. Modig puts these figures to reducing non-cut time across the cycle.
Parts and controls
The stated applications are engine housings, impellers, and turbocharger and compressor housings. Machining a complex component in a single setup reduces part handling and the number of fixtures required. The MTX can be specified with Siemens, Fanuc or Heidenhain controls.
Frequently asked questions
Parts up to three metres across, in one setup. How many fixtures does that save?
Modig does not put a number on it. What the company says is that machining a complex component in a single setup reduces part handling and the number of fixtures required - which is the claim to test against your own part families. On an impeller or a turbocharger housing, where each setup is a clamping operation and a chance to lose position, the saving is in setups rather than in minutes per part.
It takes Siemens, Fanuc or Heidenhain controls. What does that mean for a plant running mixed CNC?
The MTX is not tied to one control brand. Siemens, Fanuc and Heidenhain are all available, which means a plant can specify the control its programmers already work with rather than retraining around a new one. The source does not go further than listing the three options - it does not say how the control packages differ in detail.
The heads are torque-motor driven on either an A or B axis. Why offer both?
The source does not say. It states that torque-motor-driven tilting heads are available on an A axis or a B axis and that this gives continuous five-axis capability. Which axis suits a given part depends on the geometry, the work envelope and how the part is fixtured - but that reasoning is yours to work through with the machine builder, not something the announcement settles.
What sizes are available?
Several. Modig says the MTX is available in several machine sizes, with the envelope covering parts up to 3,000 mm in diameter and 1,950 mm in height, weighing as much as 8,500 kg. The specific size that fits a given part family is a conversation with the supplier.
What are the rapid moves and acceleration figures?
Rapid moves run to 60 m/min and acceleration to 7 m/s2, which Modig links to reduced non-cut time across the cycle. On a part this size the machine spends a lot of its time moving between features rather than cutting, so those two figures bear directly on cycle time.
