Function introduction:
This machine tool is mainly used for processing of non-circular piston pinholes, including tapered holes, curved holes, hyperbolic holes and superimposed elliptical holes (applicable to ETK2806C).
The standard double-channel SIEMENS 828D system is adopted, for which the programming is flexible and convenient, and the reliability is high.
Equipped with micro-displacement boring servo device. The micro-displacement motion of the boring bar is completed in the condition of high-speed rotation of the spindle, which has the automatic dynamic balancing function and can maintain the high operation precision of spindle. The size of the pinhole can be fine-tuned by program, and the shape and the relevant position of the hole can be adjusted by program.
Double -spindle and double-carriage structure is adopted, which is capable of processing two pistons simultaneously/separately with extremely high processing efficiency, especially suitable for automatic production of gasoline engine pistons.
Equipped with high-precision eddy-current separator chip removal device with high filtration precision, chip-removal laterally or backward can be chosen.
