Improving grinding performance by controlling air

01-09-2011  1. Introduction. In industry, grinding is commonly used as a finishing or semi-finishing operation. In this process, high specific heat is generated, and to dissipate this heat, large amount of grinding fluid is commonly used .The grinding wheel, rotating at a high speed, generates a stiff air layer around the wheel, and this air layer restricts fluid to reach deep inside the grinding zone.

Basics of Grinding - Stanford University

grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.

More

Factors affecting proper coolant

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.

Tool Cooling System Nex Flow Air Products

Frigid-X™ Tool Cooling System – How It Works. Compressed air enters at point (A) into the vortex tube component of the tool cooler. The vortex tube splits the compressed air into a cold (B) and a hot (C) stream of air. The hot air from the vortex tube is vented to the atmosphere at point (D) after being muffled to reduce noise using an internal muffling piece and a sintered plastic sleeve.

Laminar flow - Wikipedia

Because air has viscosity, this layer of air tends to adhere to the wing. As the wing moves forward through the air, the boundary layer at first flows smoothly over the streamlined shape of the airfoil. Here, the flow is laminar and the boundary layer is a laminar layer. Prandtl applied the concept of the laminar boundary layer to airfoils in 1904.

But every metal grinding application produces sparks, and the flow of those sparks can be read as a visual ammeter of sorts. Exactly how those sparks from the workpiece flow can tell you a lot about how effective the grinding really is. In most applications, sparks should flow about 3 to 4 feet away from the workpiece, in a consistent manner.
