Precision Lapping Precise Lapping Lapping Process

The pressure on the parts and the duration of the process can be finely tuned to accommodate for the part material and the final finish required. Under perfect conditions, parts can be lapped to within 10 to 20 millionths of an inch flatness. Although lapping is an abrasive process, it differs from fine grinding or honing because it uses a loose style abrasive instead of bonded abrasives like

Espresso Grinding: The Ideal Grind CoffeeReview

The greater pressure exerted by the machine, the more uniform the grind needs to be. Small steam-pressure machines will make a reasonably flavorful espresso with a relatively inconsistent grind of the kind produced by inexpensive home grinders. The larger pump and piston machines require a much more uniform grind, which can be produced only by a commercial grinder or by one of the more

Factors affecting proper coolant application when

11/08/2017· Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.
