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.
The automatic vibration polishing machine. The VIBROTECH 300 is a vibrating polishing machine of Ø 305mm reliable and robust. Vibration polishing is an ultra-soft technique suitable for the super-ﬁnishing stages and particularly for the samples to be analysed in EBSD (electron backscatter diffraction) or AFM (atomic force microscopy). This polishing method makes it possible to save inclusions and to eliminate surface hardening. Very easy to use, the frequency and amplitude of the vibrations can be modiﬁed in real time.
