Structural Features and Configuration of Planer Type Boring and Milling Machine:
The spindle gearbox with optimized speed ratio enables high torque at low speeds and high-speed finish machining.
The spindle adopts "hydrostatic enhanced variable preload tapered roller bearings", which can dynamically adjust the preload force according to the operating speed of the spindle to stabilize spindle precision.
The spindle is equipped with a temperature control system featuring an automatic compensation function for thermal elongation of the boring shaft.
Crossed roller bearings are used for centering and load bearing of the numerical control rotary table, fitted with a "double anti-backlash gearbox".
