AUTOMATIC METALLOGRAPHIC POLISHING MACHINE CLMM-20
AUTOMATIC METALLOGRAPHIC POLISHING MACHINE 

TECHNICAL DETAIL

Metallurgical Polishing Machine

Double Disk

Disk Diameter > 200mm

Adjustable rotation speed 50-600rpm

Flexible waterjet

AC motor with capacity >0.5HP

Loading range: 10-200N

Specimen preparing time: 0-999seconds

Max. diameter of specimen: 30mm

Power supply: 220 V 50Hz

Specimen mounting

Double grinding & polishing discs.

Six pieces 30mm samples can be grinded and polished simultaneously.

Both grinding disc and polishing head adopt stepless speed control, and the rotating direction of grinding disc can be shifted.

Electric central force holding, fix the sample and then it can complete the whole process of grinding and polishing, and this can ensure the plane parallelism of sample.

The loading force can be adjusted during running process.

Working time presetting

Quick exchanging disc. The working disc can be changed and replaced swiftly.
