About This Product
Polishing is the final stage in producing a flat, smooth, scratch-free and mirror-like surface on a metal sample, which is needed for qualitative and quantitative metallographic interpretation. In this machine the motor spindle is driven from the motor shaft through a friction mechanism, and the polishing discs are fitted on the shaft and locked by a nut. The shaft runs in two bearings held in a bearing holder.
