Tianjin famous cutting disc manufacturers can choose stable steady letter, [Tianjin] sheet metal cutting, metal cutting disc stability can be provided by the steady letter. We are Tianjin stable steady letter can Abrasives Co., Ltd. (www.tjwxwk.com) located at: Tianjin specializing in: grinding, cutting, angle grinding, a hundred blades [Tianjin stable steady letter can be abrasive abrasive limited Company to promote your product ---- star diamond cutting discs cutting discs] feed speed feed speed incurs sawing stone feed rate. It's the size of the impact of cutting rates, the blade and the cutting force by the heat dissipation area. Its value should be based on the nature of the stone to be sawing selected. In general, cutting softer stone, such as marble, may be appropriate to increase the feed rate Tianjin metal cutting, if the feed rate is too low specification sheet metal cutting, sawing rate increase is more conducive. Sawing fine structure, relatively homogeneous granite, may be appropriate to increase the feed rate, if the feed rate is too low, diamond blade easily be polished. But when sawing UNEVEN coarse structure of granite, the feed rate should be reduced, otherwise it will cause fragmentation diamond blade vibration resulting in reduced cutting rates. Granite cutting feed rate usually within 9m ~ 12m / min range selected. [Tianjin letter stable steady Abrasives Co., you can promote the star products ---- cutting discs] 3). Thin cutting wheel cutting sheet metal to use more fine-grained model, and generally thinner the thickness of its grit size will correspondingly fine, good surface quality. However, the finer the grit size corresponding sharpness cut down the feed rate to be reduced accordingly to accommodate the abrasive grit machinability. 4). Thin cutting wheel cutting depth is generally based on the cutting parts by the user to set the cutting sheet metal, which mostly uses cutting creep feed grinding process, the depth of a cut to. Such thin cutting wheel due to poor cutting conditions (mostly three surface contact with the workpiece), making it difficult to heat, and therefore to increase (flow, pressure) cooling of the cutting area. 5) When the cutting wheel at the user has just appeared on the machine does not move or cut workpiece chipping, the proposal to increase the cutting speed or reduce the amount of feed; When cut after a period of time does not move or chipping, it is recommended to use Whetstone appropriate granularity on the surface of the blade wheel to adjust its sharpness.
