Crack generation and the effect of in-process electro …

 · The depth of grinding of region (a) is 2 #m, region (b) 11 #m, and region (c) 100 pm. In region (c) surface crack propagation occurs in the grinding direction as well as in the direction perpendicular to it. Thus the depth of grinding has an important effect on crack

The Grindaix multifunction nozzle – grindaix

The cooling nozzle to cool the grinding wheel, the cleaning nozzle to clean the grinding wheel coating from clogging and abrasion and the GRX-LAS Liquid Air Spoiler. The Liquid Air Spoiler GRX-LAS diverts the air cushion, which is created by a fast rotating grinding wheel, away from the grinding wheel and thus improves the coolant supply to the contact point.

Nozzles and grinding fluids.

 · While most people agree that grinding fluids are important for precision grinding, few give serious thought to the nozzle, hoses, and connectors that deliver the fluid to the grinding zone. However, the importance of nozzles and other parts of this delivery system on grinding wheel performance was the subject of a recent program at the Grinding Center.

Improving grinding fluid delivery using pneumatic barrier …

Grinding fluid is commonly applied to control grinding defects caused by high grinding zone temperature. Delivery of fluid to the grinding zone is obstructed by the formation of a stiff air layer around the grinding wheel. This results in huge wastage of grinding fluid. In the present paper, results of using a pneumatic barrier and a compound nozzle are discussed with respect to delivering ...

 · This scrubber nozzle requires a ¼" NPT thread to attach it to a grinding machine (¼ MEG). The 4006 marking means the nozzle has a 40° fan angle and a 6-gpm flow rate at 4,000 psi. High-pressure scrubber nozzles are typically the flat-fan type, where the width of the fan increases with distance from the wheel.
