Petrographic Thin Section Polishing Machine

Kemet 300LVAC2 Polishing Machine

The Kemet 300LVAC2 Special purpose polishing machine is designed to work alongside the Kemtech III Geological lapping machine for polishing geological mounted samples. The basic machine has a 300mm diameter polishing plate. All drive elements are mounted on a heavy duty aluminium alloy casting, giving vibration free operation and silent running. Water inlet with control valve are standard features. The control panel has a process timer, variable speed control and forward / reverse control switch and its own vacuum pump and connectors to suit Kemet vacuum jigs (not supplied with the machine).

FORCIPOL-TS, when coupled with FORCIMAT-TS, becomes an automatic thin section preparation system. FORCIPOL-TS is a versatile, durable and reliable grinding/polishing machine. FORCIMAT-TS is a low speed automatic head and is mounted on a rigid hardened post which is fixed to the base of the FORCIPOL-TS grinder/polisher. It can be adapted easily and rapidly positioned by means of a quick-locking clamping mechanism.

FORCIPOL-TS can accommodate 300 mm diameter wheels with variable speeds between 50-600 RPM. The modern electronics provide a smooth speed variation with soft start and stop. The working wheel is powered by a high torque 1.0 HP electric motor with both clockwise and counterclockwise wheel rotation possibility. By using appropriate working discs, it can carry grinding, lapping and polishing processes very smoothly. 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 quiet and vibration free operation. Water inlet and flexible water outlets with control valves for wet grinding are standard features.

FORCIMAT-TS is driven by a 100 Watt DC motor and adjustable from 25 to 50 RPM speed which provides high torque for big specimens and allows long operation time. Speed of head is specially adjusted for thin section and petrographic sample preparation. The pneumatically applied individual force is adjustable between 5 N (1.1 lb.) and 60 N (13.5 lb.) from the front panel and is displayed on a gauge. The housing is made of ABS with a touchpad front panel.

Automatic Disc Cleaning and drying function can be activated with a single button to obtain perfectly cleaned disc surfaces in seconds. Smart Water Saving feature allows tons of water saving over the years. When needed, FORCIMAT-TS can work in manual mode to allow prepare specimens by hand.

Modern touch pad controls with ergonomic turn knob allows fast and easy setting of parameters and increases productivity. Sample force, wheel speed, sample holder speed, operation time, motor on/off and water on/off functions can be set in seconds. When the start button is pressed, both the FORCIMAT-TS and FORCIPOL-TS start operating simultaneously. Cooling water is automatically activated and deactivated at the beginning and end of operation. The wheel/head speed and operation time are digitally displayed. All parameters can be changed during operation. The last parameter settings are always retained in the memory. Upon completion of the cycle, both instruments stop and an audio signal notifies the operator.

Specially Designed Thin Section Holders

Specially designed thin sections holders are used for lapping and polishing of thin sections. LAP-TS has special Boron Carbide stops which precisely determine final thickness of specimen on the glass slide. The final thickness of specimens will be between 25 and 35 µm. POL-TS is used for polishing processes to provide smooth surface for microscopic examination.
