Understanding the Marking System for Grinding Wheels

The rotational speed, given in revolutions per minute. For example, 8500rpm. For smaller grinding wheels (below 80mm in diameter), the maximum operating speed is provided on a separate notice which must be stored alongside the wheel. For high speeds, colour-coded stripes are also marked across the centre of the wheel. The colours are: 50m/s

Ultra-high-speed grinding spindle characteristics upon

May 01, 2002· For a precision-built high-speed-grinding spindle unit, the heat developed at the rolling element (H f) increases abruptly with spin speed of the rolling element (ω b), as stated in Eq. (14) : (14) H f =ω b ( 0.0016fP+0.00044ω b ), where f is the friction coefficient between the Si 3 N 4 ball and steel race, and P is the radial force in N.

Study on the grinding of P/M high speed steel ASP60

Apr 01, 1999· The specimen ASP6O is a powdered metallurgy high speed steel with a hardness of 67–69 Rockwell C, and dimensions of 7×7×20 mm. The grinding wheel employed here is of the type NORTON 5SG120-JVSG-l, the size of which is 180 mmD×6.4 mmT×31.75 mmH. Another specimen W1 tool steel has been used in this experiment for comparison with ASP60.

High speed grinding of silicon nitride with resin bond

Nov 01, 2003· Previous studies (e.g. ) have indicated that high speed grinding could be an economic strategy for achieving “ductile” mode grinding. Theoretically, an increase in wheel speed results in a reduction in maximum chip thickness and hence grinding force [5],which should promote ductile flow by reducing the tendency for brittle fracture.
