Machining 101: What is Grinding? | Modern Machine Shop

Precision grinding is a middle-ground between metal removal and part size control, and serves as the basis for creep feed grinding, slot grinding and high-efficiency deep grinding. In ultra-precision grinding, little to no actual cutting occurs, but sliding action from very fine grains rubs the workpiece surface to a high finish.

Hard Turning as an Alternative to Grinding | Production ...

Editor Emeritus, Production Machining. Hard turning is typically defined as the turning of a part or barstock of harder than 45HRC on a lathe or turning center. Since surface roughness of Rmax/Rz=1.6s can be achieved, hard turning is often considered a replacement for grinding operations or as a pre-grinding process.

High-Velocity Grind | Cutting Tool Engineering

Because the hard particles in PComP coatings are nanostructured, anywhere from 80nm to 600nm, the grinding wheel does not cut through them; they are instead removed with the grinding chips. This means that aluminum-oxide or silicon-carbide wheels can be used instead of diamond wheels.

Managing Grinding Forces and Abrasive Sharpness | …

The plowed material slides — more on that later — on the grinding wheel surface prior to leaving the grind zone. The microchips produced by this deformation can clog the pores of the grinding wheel. The chances of this problem are increased by factors such as insufficient grain exposure, extremely hard wheel bonds and gummy workpiece material.

The finishing processes of parts have been carried out mainly by abrasive grinding techniques. Grinding is a theoretically well-elaborated and widespread machining process. That is why its replacement by another metal removal technique, hard cutting, requires very careful examination.

All about grinding hard concrete - Concrete Grinder Sales

Hard concrete. When grinding hard concrete the hard concrete does not produce much sand. The diamonds cut, blunt and break as normal, but the metal bond surrounding them is not worn away easily without the sand so the diamonds do not become exposed as much as with medium hardness or soft concrete.
