Machining 101: What is Grinding? | Modern Machine Shop
While milling can complete these tasks, grinding improves surface finish, has less expensive tooling and allows contours to be dressed into the profile of the wheel — making it much more cost-effective for very hard or abrasive surfaces. Centerless grinding creates cylindrical forms at extremely close tolerances.

Leveling Course vs. Milling. For many situations, milling may be a superior alternative to a leveling course. Leveling course quantities are difficult to accurately estimate and leveling course thicknesses are usually small, precluding the use of nuclear gauge density testing. Thus, adequate mix density is difficult to achieve and measure.

Precision grinding achieves levels of accuracy Blanchard grinding can't, but it saces speed in the process. If speed is more important than accuracy for a project, the metal fabricators will more likely opt for Blanchard grinding. Blanchard vs. Precision Grinding. Which is better: Blanchard or precision grinding?
Grinding vs Scraping vs Milling and CNC? : Machinists
The benefit of scraping over milling or grinding is that the part doesn't get distorted from clamping or cutting loads. The material removal is tiny, so a machine wouldn't save much time over doing it by hand. The oil retention from the flakes can be done either way. This is the main reason, lack of distortion.

Milling vs .Grinding - MC X/MC XL
In the past, CEREC terminology has always referred to the cutting process as "milling" . However, the diamond burs (ex. 12, 12s, 20) actually use a grinding process to grind away the block material. The carbide and zirconia burs (Shaper 25rz, Shaper 25, finisher 10) use a literal milling process to cut and slice the material.
TECHNICAL NOTES 8 GRINDING R. P. King
2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge. This energy is required to cause grinding of the material in the mill. The shape and
