One-piece 30-degree slant bed made out of gray cast iron, which has superb vibration absorption characteristics, provides rigid foundation for all machine components.
Such design endures long-term machining accuracy and consistency.
- Heavy-duty headstock machined from one-piece casting. Reinforced with radiator fan-like pin tube rib design dissipates heat generated by axis movements, maintaining minimal thermal expansion
The sub-spindle with full C-axis control enables precise machining on the rear side of the workpiece. Its powerful built-in motor with an oil cooling system delivers fast acceleration, high torque and exceptional precision.
The 12-station turret with 24 index positions (half-indexing) offers increased tool capacity. The turret design incorporates a 245 mm large-diameter Curvic coupling, delivering powerful clamping force of 83.8 kN (18,839 lbf) to ensure high rigidity and enhanced cutting performance.
Programmable tailstock body & quill make easier to adjust tailstock position and minimize setup time. MT#5 built-in live center tailstock provided as standard, ensures superior machining rigidity.
Y-axis allows side milling, off-center drilling and grooving. This result in better machining accuracy and also enable more complex shape machining capability compared to conventional 2 and 3 axis turning center. The simultaneous operation of the X-axis and the Ys-axis creates the Y-axis movement.
