YHJ2M86108 Automatic positioning surface polishing machine

The equipment is intermittent multi-station, multi-process, synchronous and efficient surface polishing equipment. The upper disc adopts two independent lifting and adjusting polishing disks, and different consumables can be installed at the same time. The lower disc adopts 3 working stations, and 3 working stations are rotated intermittently, which can realize the simultaneous processing of 2 working stations, the 3rd working position is used to take and put the work piece, so as to realize the uninterrupted working mode, and the automatic loading and unloading interface is reserved, which is convenient to realize the full-automatic assembly line operation. The device is used to polish the back of ipads, laptop panels, keyboards, polished surfaces of Powder metallurgy cases, mobile phone metal cases, covers, and other hard, brittle materials.

Equipment Highlights

1.3 groups of station lower disc are equipped with independent servo motor drive, which can independently control, speed control and positive and negative rotation.

2. Adopt new vacuum adsorption structure and vacuum control system, can control each group of vacuum adsorption independently.

3, with a pressure sensor, can real-time monitoring of the product polishing pressure, and real-time adjustment.

4, each upper plate station can be different according to the process requirements, the configuration of different polishing consumables, speed and direction can be independently controlled.  

5. The lower disc work station can backwash the vacuum pipeline independently, the backwashing pressure is high, the efficiency is fast, the water consumption is reduced greatly.  

6, with an independent workpiece cleaning and cleaning air cleaning mechanism, so that the finished workpiece more clean.

7, the hanging disc has the mechanical safety lock function when the machine stops, prevents the hanging disc falling hidden danger when changing consumables or overhauling.
