Horizontal Machining 5-Axis
a51nx-5XU: Bringing the proven performance of Makino’s nx products to 5-axis part production.
Manufacturers of medical, aerospace, prototype and complex multi-face parts have long understood the advantages of 5-axis machining. Five-axis machining capability can improve productivity and quality simply by consolidating operations.
The linear X-, Y- and Z-axes of the a51nx-5XU are built from the same tiered column, bed and rigid casting structure as Makino’s industry-leading a51nx. Rotary B- and C-axis motion comes from a pair of responsive (75 / 150 rpm) direct-drive motors. Both motors are housed in an integral cast structure that eliminates the stack-up errors and loss of rigidity common with table-on-table 5-axis designs. The contoured table casting provides ideal spindle accessibility to the workpiece. The C-axis cables are routed through the splash-guard ceiling, ensuring reliability and chip-free operation.
What makes the a51nx-5XU stand apart from other small 5-axis machining solutions is its horizontal orientation and integrated workpiece automation. Horizontal orientation offers ideal chip shedding. Avoiding recutting of chips, especially in aerospace and medical materials, improves tool life and part surface finish. Loading parts in a 5-axis horizontal orientation, however, can lead to some material-handling challenges. The a51nx-5XU eliminates these challenges with its unique work-pallet magazine.
