The axes controlled by the machine are:
• X axis
• Transversal axes of the Y axis carriage
• Vertical Z axes of the Z axis carriages
• Rotating A axes of the operating heads
• Rotating B axes of the operating heads
Each axis has a positive and a negative direction. The diagram shows the positive direction for
each axis. All movements take place on over-sized bearing skids that ensure solidity and reliability
over time. All movements are driven by brushless motors (maintenance free) and preloaded
circulating ball screws that provide for high accelerations.
