The turret milling machine can also be called a rocker arm milling machine, rocker arm milling, or universal milling. The turret milling machine has a compact structure, small size, and high flexibility. The milling head can rotate 90 degrees left and right, and 45 degrees back and forth. The rocker arm can not only extend and retract forward and backward, but also rotate 360 degrees in the horizontal plane, greatly improving the effective working range of the machine tool. The body of the universal rocker arm milling machine is made of high-grade cast iron, which has high accuracy and long service life after artificial aging treatment. The lifting platforms all use rectangular guide rails with multiple contact surfaces and sufficient rigidity. After high-frequency processing and precision grinding, the slide is coated with plastic, resulting in excellent motion accuracy and lifespan. The spindle of the universal rocker arm milling machine is made of chromium molybdenum alloy and equipped with precision grade angular contact bearings. After quenching and tempering treatment and precision grinding, it has strong cutting force and high accuracy.
