High power and high torque for machining tough materials
- High stock removal capability
- Structural rigidity and high damping capability of vibrations
- High dynamics in terms of acceleration andspeed
- Axes stroke X = 3300 (4500), Y = 2100, Z = 1000 mm
- Constant accuracy on the whole operating volume
- High configurability and compactness
- Full machine enclosure
- Reduced foundation requirements
- 5 axis mechanically driven milling head (up to 42 kW and 1470 Nm, 3000 or 6000 rpm), alternatively electrospindle 15000 or 27000 rpm
Architecture and structure
- Tarkus is also innovative thanks to its structural design, introducing the exclusive Dual Frame HV architecture with fixed gantry in X-axis (3300/4500 mm) and mobile gantry in Z-axis, which grants almost constant rigidity on the whole operating volume
- This structural solution, combined with Jobs proprietary spindle head technology, has made it possible to create a sleeveless machine guaranteeing maximum performance in terms of rigidity and precision along the entire length of the Z-axis
- The particular architecture of Y-axis saddle, combined with the geometry of the specific heads, makes it possible to reach the part to be machined in depth without risking collision with the crossbeam
Milling heads
Tarkus can be equipped with four different milling heads, based on the application sector where the machine will be used:- Milling head T35/T32. The newly-designed main head version, called T35, featuring a spindle offset from the C-axis, is especially suitable for aerospace industry machining and milling super tough materials such as Inconel and titanium. In addition to this heavy-duty head, head T32 is available, designed for machining less demanding materials. It boasts a high removal capacity
- TMX milling head. The TMX head, also equipped with offset, is especially suited for use in precision general engineering. The solidness of this indexed head means it can also be used for the most sensitive boring operations, thanks to the presence of two Hirth rings one on each of the fork shoulders
- T3K milling head. The T3K head is available for machining dies or sculptured surfaces in general, with two choices of electrospindles equipped with power up to 44 kW and speed up to 27000 rpm.
Automation
- Tarkus can be equipped with a chain-type magazine that can hold 32 to 64 tools; other magazines are available with static configurations for up to180 tools
- The table offering remarkable dimensional (up to 4000x1500 mm - 157x59 inch) and loading capabilities assures the highest ergonomics
- The machine configuration with double pallet table enables pendular machining of two components with work piece change in masked time
The machine is successful at machining very tough materials (titanium, inconel, stainless and special steel, alloy steel and others) mainly for:
- for the aviation industry
- high-precision general engineering fields
- molds and dies
- To effectively manage the production process in unmanned shifts automated tool setting and checking, power monitoring, tool life and twin-tool managing software are available
- Very high pressure cooling system:
- 70 bar (1015 psi) inside tool
- 15 bar (217 psi) outside tool, 80 l/min
- tank 1000 or 2000 l
- self-cleaning filter
- Tool cooling, available options:
- Spray Mist
- Air blow
- Water coolant with filter and tank
- Cooling is available inside and/or outside the tool for all options
