4000A Rectifier Electro Polishing Machine

4000A rectifier electro polishing machine
  

Technical Parameters

Product usage
It is dedicated to aluminum and aluminum alloy hard anodic oxidation of surface treatment.

Product features
In the oxidation process, the work piece produces the gas unceasingly, has hindered the oxidized continuation, causes the oxide film to be loose, to be porous, while the pulse power source is  intermittently changing from  high current to low current ,in favor of  the gas separation, easy to be film, the film will be thickened and compact ,The thickness ,hardness and colour can be greatly improved.

The main features :
1.Pulse frequency adjustable from 0.4-25HZ,the performance is better than Italy CISART and TECNO power supply  ,its maximum frequency is 3HZ,duty cycle is adjustable,

2.The pulse is around 90 vertical along, the pulse is most suitable for electrochemical. The pulse and superposition level height can be arbitrary adjustable from scratch.

3.Soft start-up time is from 1-32 minutes adjustable, for pulsed soft start, especially suitable for hard anode oxidation process.

4.Running time 1-256 minutes adjustable (not including soft start-up time). Finish the work time, automatic shutdown.

5.It has a variety of work options: pure pulse, pulse superposition, DC, etc. In the rectifier run-time can display the pulse frequency, duty cycle, pulse peak, pulse-based etc all data

6.At runtime, free to modify and adjust a variety of data and storage. It can save 35 years.

7.As for hard anodized characteristics, it works for stable current and limit voltage. When extend working hours, the oxide film thickness raise .if the output voltage rises to the set of data, the voltage to stop rising and the current will gradually decline.

8.It has output over-current, short circuit, phase sequence fault and lack phase protection functions.

9.The transformer coil winding and the bus-bar all use the imported electrolytic copper (copper content 99.99%) for manufacture,the electric conductivity is good, the current efficiency is higher;

10.The transformer coil uses twice vacuum dipping lacquer processing craft, the insulating property and the anticorrosion performance is much better;
