Integrated with a two-axis trunnion table, Chevalier Machinery’s QP5X-400 is a 40-taper, high-speed VMC suitable for five-axis simultaneous or 4+1-axis applications in the aerospace, medical and moldmaking industries.

Major parts of the machine are constructed of Meehanite cast iron, offering high rigidity and stability. The column design’s inverted-Y shape and one-piece construction adds to that rigidity and stability. Pre-tensioned Class C3 ballscrews are used in all three axes, and all servomotors are directly coupled to the ballscrews, increasing movement sensitivity while reducing backlash. The machine offers a table load of 220 lbs and can handle workpieces as large as 15.7" × 13.7". XYZ travel is 20.5" × 15.8" × 15". 

The 12.6" trunnion table features a heavy-duty, three-piece cross-roller bearing for excellent part loading and machining capability, and ±10" accuracy for the A axis. The large-diameter Big Plus spindle uses four-piece, P4-Class, high-precision angular-contact ball bearings to increase rigidity and maintain accuracy during high-speed machining. A direct drive spindle is standard for low noise, vibration and thermal expansion. The VMC provides fast interpolation, with a high-linear rapid speed of 1,417/1,417/1,181 ipm. The spindle taper is #40, spindle power is 25 hp, and spindle speed is 10,000 rpm (optional 12,000 and 15,000). Tool capacity is 30+1.
