Sample Preparation Grinding & Polishing

These sample preparation systems are designed for fully automated materialographic sample preparation for consistent and reproducible specimen quality. Digiprep’s Automatic Head controls the force applied precisely and specimens are prepared exactly the same way everytime, independent of operator skills. With the ability to store and recall preparation programs on the LCD screen, same consistent results are obtained. Efficiency is further increased by adding Dosimat Peristaltic Dispensing Unit for automation and control of consumable consumption.

automated sample preparation

Digiprep’s variable speed base unit is available in two version; Digiprep 251 with 250 mm diameter wheel and Digiprep 301 with 300 mm diameter wheel. The base unit is powered by a high torque 1,0 HP electric motor. The state of the art frequency converter allows smooth speed variation (50-600 rpm) with soft start and soft stop.

The stylish and functional GRP housing is corrosion free and easy to clean. Molded wheel bowls and drains eliminate leaks and the build-up of residue is prevented by constant flushing of the bowl.

The drive elements are fixed on heavy duty aluminium alloy casting. The wheels are mounted on ball bearings allowing the application of high pressures to prepare even large specimens. Ball bearings used provide quite and vibration free operation. When required, the base unit can be operated in manual mode, as well

Digiprep’s programmable Automatic Head is HMI touch screen controlled and with the Base Unit, thus creating automatic preparation system. It is used to prepare high volumes of metallographic, ceramic and mineralogical specimens with consistent reproducible quality. The 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. The Automatic Head is mounted to a hardened steel post which is affixed to the cast base of the grinder / polisher. The force on the specimen. “individual” or “central” is pneumatically controlled by apressure transducer. The system is enclosed in a GRP housing with touch screen LCD. TheAutomatic Head is rapidly positioned via a quick-locking clamping lever. The “soft start and stop” feature automatically starts the sequence with a low inital force which is then increased to the preset.
