How long will a cast iron plate last?
The lifespan of a Logitech cast iron plate is dependent on the usage and material being processed. Typically the plate should be replaced once the groove depth is below (1mm) 800 micron.
If it is a plain plate it should be replaced when the height from the process surface to the centre recess is below 1mm.

Which pad is suitable for me?
Logitech can provide a wide variety of polishing pads and cloths of different characteristics and sizes to meet the different requirements of surface finish, surface roughness and flatness across various materials. The pad material, hardness, compressability and structure all have a bearing on the results that will be achieved.
Generally where the sample size is 20cm2 / 2″ diameter or less we recommend that a plain pad or plate is used for processing. Where the samples are larger than these sizes grooves are required to allow lapping abrasive or polishing slurry to pass uniformly between the sample and the pad or plate.
