Portable apparatus for mechanical grinding and polishing ‘in-situ”. The ELECTER EVOLUTION is ideal for preparation of surfaces before chemical etching or polishing and electrolytic etching. • Strong case for transport. • Control panel. • Electronic speed control. • 2 outlets for motor connection. • Selection of rotation direction. • Torque motor 1500 to 25000 RPM. • Reducer 1/4 increasing the power by 4. • Tool holder with 90° bevel gear. • Voltage: 220 Volts. • Built in accordance with EC standards.
ELECTRO-POLISHING UNIT. The Electro-polishing unit is designed to withstand both mechanical shock and corrosion. It includes a body that forms a base for the moving assembly and the electrolyte reservoir, the moving assembly with a pump and a motor, a cooling coil and an electro-polishing chamber equipped with electrodes. The DC current produces the anodic dissolution of the surface of the metal specimen inside the electrolysis chamber. A ﬂat, polished surface is obtained in a few seconds, ready for microscopic observation. • PVC base, with rack and pinion system, crank driven vertical movement. • Moving assembly in PVC with circulation pump and electric motor. • Motor with variable speed to adjust the electrolyte ﬂow. • Stainless steel cooling coil. • 5 PVC covers with openings of different shapes and sizes. • Adjustable plastic-coated stainless steel rod as current feeder. • 2l glass beaker.
• Input 220 volts single phase 50 or 60 Hz. • Adjustable output from 0 to 100 volts, with display of voltage. • Direct current rectiﬁed by silicon diodes. • Ammeter with 2 ranges, 0 to 10 and 0 to 20 Amp. • Programmation managed by PLC with memorization of the polishing and etching ranges. • 2 timers, polishing and etching. • Rear output to electro-polishing unit and front connector for work with special clamp-type holder. • Time delays for starting and electrolyte ﬂow control. • Built in accordance with EC standards.
