8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.
Grinding is a combination of rubbing, ploughing and cutting (actual chip formation with contribution of each being highly governed by grit geometry, work material characteristics, grinding loop stiffness and the grinding velocity The various stages of grinding and grinding force with grit depth of cut is shown in Figure 6.
How to Read a Grinding Wheel Spec. Posted: June 15, 2014. Categories: Blog. Diameter of grinding wheel x Thickness of grinding wheel x size of arbor hole -. We will reference the AA Abrasives #60397 - 12x2x1-1/4 Pedestal Grinding Wheel T-1 Vitrified A36 - from our Vitrified Bonded Grinding Wheel Series. 12=Diameter x 2=Thickness x 1-1/4=Arbor Hole.
30 degree stone will lower/narrow seat contact on valve. 60 will raise/narrow the seat from the bottom. Other basic stones I use are a 15 and a 70 degree stone to smooth some seats. Stones can be dressed to about any angles and some operators have their pet setups.. I like 1/2 degree interference fit so i grind valves accordingly.
Grinding wheels are marked with a specification that consists of alternating letters and numbers separated by dashes. Large wheels carry at least four and as many as six terms, but small wheels are marked only with grain size and grade – the other information is on the packaging. In order, the terms refer to: 1. Abrasive type (a letter).
pends on the abrasive grit size, but also on the grinding and dressing method. Coarsely dressed grin-ding wheels yield higher perfor-mance, but also produce a rougher surface. When grinding profiles or small radii, the particle size has a direct influence on the selection of the specification. The dressing
