Tips for choosing the right size of Grindestones<\/strong><\/p>\n

The dimensions of the grindstones are always given in length x width x height (LxWxH). The largest possible grinding surface should always be used for each machine (length x width). The height (H) of the grinding stone is determined by the diameter ratios of the commutator and housing. Commutator whetstones (article no. SPXxx): The grindstone should have a width (B) that covers at least \u00be of the length of the flaps as long as it fits comfortably between the brush yokes. For normal operation, three or four different sizes should suffice for each operation. Once the approximate dimensions have been determined, the next most suitable article no. can be selected.<\/p>\n

Gentle, light effect. Soft, loosely bounded grain. Self-cleaning stone through abrasion. No erosion or scratching of the copper. Often also called “Pumice or Chalk Stone”.<\/h5>\n
