Features

Using 4-Motor motion mode, that is, the upper fixed plate, lower fixed plate, ring gear, and center gear motors can all be independently controlled without changing the direction of the ring gear and center gear. Easy to realize the cruise ship Positive and negative rotation, realizing the positive and negative rotation of the planetary wheel can stably process the workpiece so as to realize the self-adaptive fixation of the fixed disk. The center tooth can also be individually reversed for the repair of the disk.

4-Motor motion mode makes the power source more dispersed, the machine is more stable, the noise is lower, and the precision is higher; the adaptability of the star wheel operation is improved, and the star wheel wears Can also be reduced to a minimum Limit, greatly extend the service life of the star wheel.

The CPU can assign the rotation speed of the upper and lower fixing plate, the lower fixing plate, the center gear, and the ring gear by itself, or the operator can separately set the upper and lower fixing plate and the center gear according to their own calculations and experience. , Ring gear setting closed Appropriate rotation speed can facilitate the operator to better design the rotation and revolution trajectory of the workpiece, and set any rotation and revolution ratio to achieve the best processing conditions and optimal processing results.

The ring gear and the center tooth move up and down at the same time, making it easier to pick and place the workpiece;

SMC precision electric proportional control valve + pressure sensor realizes steady pressure changes, which can eliminate excess load and extra impact to the greatest extent possible to protect the safety of the processed workpiece; The pressure of plate setting and starting plate can be manually set manually, which protects the safety of the processed workpiece to the maximum extent.

Mitsubishi large-size digital man-machine interface + Mitsubishi high-quality PLC module, which can store 20 20-step procedures inside, greatly reducing the technical requirements for operators and greatly improving the product Pass rate.
