YL-557D-850E Educational CNC Milling Machine

► The seat structure moves laterally (in the X direction). The bed, worktable, slide seat, column, headstock, and other large parts are made of high-strength cast iron materials, shaped using resin sand technology, and stress is relieved through two aging treatments.

► These large parts are optimized by Pro/E and Ansys to improve the rigidity and stability of the large parts and the entire machine, and effectively suppress deformation and vibration of the machine tool caused by cutting forces.

► The X, Y, and Z-axis guide rail pairs adopt rolling linear guides, which feature low dynamic and static friction, high sensitivity, low high-speed vibration, low speed creep, high positioning accuracy, excellent servo drive performance, and improve the precision and stability of the machine tool.

► The X, Y, and Z-axis servo motors are directly connected to high-precision ball screws via flexible couplings, reducing intermediate links, achieving backlash-free transmission, flexible feeding, precise positioning, and high transmission accuracy.

► The Z-axis servo motor has an automatic brake function.

► In the event of a power outage, the automatic brake can firmly hold the motor shaft to prevent it from rotating, providing safety protection.

► The spindle assembly is produced by a professional Taiwanese manufacturer, with high precision and high rigidity.

► The bearing adopts a special P4-grade spindle bearing.

► After the entire spindle is assembled under constant temperature conditions, it passes dynamic balance correction and function testing, improving the lifespan and reliability of the entire spindle.
