Fully Automatic Programmable Grinding/Polishing System (operator free)

DIGIPREP Velox Automatic programmable grinding and polishing system is available with 4 grinding/polishing stations (1 coarse grinding, 1 fine grinding and 2 polishing) which can accommodate 250 mm diameter wheel as well as 300 mm. diameter wheels. The grinding/polishing stations can be configured independently according to the specific requirement of the abrasives. The vibration free, robust steel construction ensures extremely flat specimen surfaces.

The high speed grinding station with a variable speed between 100 - 1200 RPM enables quick planar/course grinding of the specimen surface. For fine grinding and polishing stations the variable speed between 50-600 RPM makes it suitable for grinding and polishing of wide range of materials. Each station can be configured for specific abrasive requirements. Water, diamond suspensions, diamond lubricant, aluminum oxide and colloidal silica dispensing are fully integrated and controlled through touch screen.

Servo-motor driven Head proceeds from one step to the next automatically securing the highest level of accuracy and reproducibility. Automatic Head can apply both "Central" and/or "Individual" forces. It can accommodate single samples as well as multi - sample holders thus offering a perfect solution for all levels of sample throughput requirements. A built-in encoder allows you to measure the amount of material removed from the surface. The desired grinding depth can be set to grind different type of samples and also for applications that needs special accuracy.

A library of 25 different preparation programs with related specimen name or number can be saved with all parameters of each grinding/polishing station which can be recalled at any time. Upon completion of the cycle, an acoustic signal lets the operator know that the cycle is over and the samples are ready for analysis. When required, it is also possible to intervene in the program and change the parameters without stopping the instrument.

Fully automatic sample cleaning station with water and ethanol is a standard accessory for DIGIPREP Velox. Optional Ultrasonic Cleaning is available to thoroughly remove all traces of contamination tightly adhering or embedded onto specimen surfaces. The level of liquid in ultrasonic cleaning station is monitored continuously and refilled automatically when the liquid level is not sufficient. After completion of the final cleaning process the sample holder is positioned above the hot air dryer for the drying process. The cleaning and the drying steps can be programmed separately for each grinding/polishing station.

Two Built-in Peristaltic Dispensers are located in the cabinet and guarantees exactly the same dosing every time. Diamond suspensions I lubricants and aluminum oxide suspensions can be fed. Dispensing parameters like; frequency, fluid selection etc. are controlled through the programme memory of the Digiprep Velox. Each dispenser has 3 peristaltic pumps for diamond suspensions I lubricant and 1 pump for aluminum oxide suspension. The liquid is dosed exactly to where the operator wants it on the polishing cloth. No vaporization or spray mist occurs.
