The DECO 42f incorporates fixed headstock technology. It has 12 axes (+ two C-axes) and mirrored design. It can machine complex operations on both ends of the part. With axis Z1 supporting the slide Z2, it is possible to work with 2 turning tools simultaneously (for example, roughing and finishing). This is achieved using the toolholders located on tool platen X1 Y1 and the slide X2Y2 Z2--again, also simultaneously machining both sides of the part, so 4 tools cutting together. The machine structure is fully protected. The S1 and S4 spindle motors are located directly on the axes (no offset drive). The stator (motor) and rotor (spindle) systems are completely new and protected. The motor is positioned (so that it can slide) on a hollow shaft, thereby offering an alternative to the heavy and expensive conventional motorized spindles. The DECO 42f has been designed as a high production output machine, which guarantees precision, even during highly demanding machining operations (very high stresses). The ballscrews are fitted with attenuators and impact compensation devices. In order to ensure stable and efficient thermal behavior (reaching constant operating temperatures quickly), all fluids (air, oil) will be fully controlled. The air is forced into the machine by powerful fans. Along its path, the cutting oil travels in pipe coils. The air then passes into the machining area and across the base frame. This air control system also allows the machine to be dry when using emulsions (thereby eliminating any signs of condensation). The cutting oil is used to cool down the spindles and revolving tools before being sprayed in the machining area. The oil then flows into the oil tank, whereupon the air pulsating in the machine cools it down again. If necessary, an optional unit can be used to cool down the oil before it is discharged from the tank (into the airflow).
