    Grinding Characteristics And Precautions For Use Of Ultra-thin Cutting Wheel

    2018-07-13 14:48:06

    1, the overall type of cutting wheel thickness thin (more than 0. 5mm below), small diameter (20-100mm), fine granularity, size and shape of the high precision, light weight, generally in the high speed conditions. The general rotational speed is 5000-4000 rpm.

    2. The base-type cutting wheel is mostly thicker (0). 5-2Mm), large diameter (100-200mm), coarse grain size, low precision, generally used in the lower speed of large-cut deep conditions. The general rotational speed is 3000-1000 rpm.

    3, ultra-thin cutting wheel more use of fine-grained, and the general thickness of the thinner abrasive granularity will be correspondingly fine, processing surface quality is good. However, the finer the granularity of the abrasive is, the sharper the cutting sharpness decreases, and the feed speed is correspondingly reduced to adapt to the machinability of the abrasive grain size.

    4. The cutting depth of ultra-thin cutting wheel is generally determined by the user according to the cutting parts, and most of the cutting adopts the slow feed grinding technology, and the depth is cut to the first time. As a result of cutting the grinding wheel thin, cutting conditions (more than 3 surface contact workpiece), so that it is difficult to heat dissipation, so to increase (flow, pressure) on the cutting area of cooling.
