GRINDING FEEDS AND SPEEDS - ABRASIVE ENGINEERING. Most cylindrical grinding machines offer a rather wide range of work rotation speeds, table traverse speeds, feed rates, and, sometimes, different wheel speeds as well. The proper selection of these variables, in combination with the choice of the grinding wheel, has a great bearing ...

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

B. Feeds & Speeds The correct balance between table speed and downfeed rate is most important. A few general rules relative to this are: o The fastest downfeed rate and table speed which give optimum ratios or rates of removal should be used. o As areas become broader than 50% of the table area, feed rates generally decrease.
