The Application Area:<\/strong><\/p>\n

\u2013 cylindrical grinding, flat grinding, internal grinding operations- producing of details for bearing industry etc.<\/p>\n

– sharpening of metal cutting tools- gear-grinding operations- thread-grinding operations- producing parts for turbine etc. Main Processed Materials\u2013 instrument steel (R18, R6M5 etc.)- bearing steel- titanium alloy- heat-resistant steel- alloy-threated steel Main Rules for Vitrified Bonded Grinding Wheels Hardness Selection1. Grinding of hard materials \u2013 soft bond.The soft bond also could be used for grinding of soft and yielding materials,such as heatproof and nonferrous alloys.2. For rough grinding should be used wheels with harder bond.3. In case of speed rising client should decrease the hardness of the bond.4. In case of large contact of grinding wheel with processed surface should be used softer bond.<\/p>\n","protected":false},"excerpt":{"rendered":"
