A double disc grinder grinds two sides of a workpiece at the same time. This provides a high degree of flatness and parallelism. For parts like piston rings that need to be ground flat on facing sides, a double disc grinder will cut production time in half. There is no need to grind the same part twice; this also reduces stress on the part.

As discussed above, conventional surface grinding cannot effectively eliminate the waviness induced by wire-sawing operation. One practically approach to overcome this is to use surface grinding to partially replace lapping, as shown in Fig. 8 …

Double-disc grinding with machines from Thielenhaus and Thielenhaus-c. Flat and stamped parts are machined on the double-disc grinding machine using a through-feed, plunge-cut or oscillation process, depending on the respective requirements.

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

Grinding burn is preventable by using a coolant jet stream with 30-50% of the circumferential speed of the grinding wheel. Needle nozzles (pdf) by Grindaix apply this and efficiently prevent grinding burn on ground parts. It is important to know the pressure directly before the needle nozzle, resulting in what coolant exit speeds and coolant ...
