Struers LectroPol-5 - LectroPol-5 System Overview

The equipment consists of a control unit and a polishing unit. The polishing unit is intended to be
used in combination with a LectroPol-5 control unit.
The polishing unit must be placed in a well ventilated area, preferably a fume cabinet, to prevent
inhalation of hazardous vapors. The polishing unit must not be used for sub-zero temperatures. A
polishing unit for polishing at low temperatures is available for this purpose.
For the low temperature polishing unit a cooling unit is required and must be purchased separately. A
pump circulates the cooling liquid through the cooling coils. The cooling unit is connected to the
polishing unit.
The operator fills and empties the electrolyte cartridges (accessories).
Before starting the process, the operator places a specimen on the polishing table. The operator
selects a suitable method, accessory, and electrolyte.
The operator makes sure that a suitable combination of electrolytes and polishing parameters is
selected for the material. The operator inserts the electrolyte cartridge in the polishing unit.
The operator starts the process. A scanning function can automatically help to determine the settings
by scanning in a pre-defined voltage range. Small layers of material are removed in the electrolytic
polishing process, and the uneven material surface is reduced to a plane area for further analysis.
The voltage and current are monitored and adjusted automatically.In case of excess heat and/or
excess power consumption the unit switches off automatically.
After use, the electrolyte cartridge must be removed and placed in a safe location.
Cleaning is carried out by using an electrolyte container filled with water.
Note
Proper maintenance is required to achieve the maximum up-time and operating
lifetime of the machine.
Note
The device is designed to be used with Struers consumables specially designed for
this purpose and this type of device.
