the commutator. The grain of the grinding wheel should be medium for rough truing, and fine for the finishing operation. Ensure that the grinding wheel does not clog, for this may cause lapping of the copper. The cuts must be small (of the order of 2 to 3/100 mm), in order to obviate tearing and crushing of the cop- ...

The following 9 pages describe our complete line of commutator grinding tools. The three salient factors in choosing a commutator resurfacing tool are: 1. Commutator bar length (or width of slip ring) matched to grinding capacity of tool. 2. Access area matched to dimensions of tool to ensure working clearance. 3.

If the sparks go all the way around the copper strips, also called the commutator, the armature has shorted. That means the insulation between the wires and the iron has broken down in the inside of the armature. Some times it can be as simple as a short between the bars, the copper strips, of the commutator. With the tool unpluged, use an air ...

Longer lasting than grinding bits, these abrasive cones remove heavy amounts of material and leave a rough surface texture. They have a threaded insert that attaches to the spindle on a straight grinder. Use in corners and inside castings. Files for Hardened Metals, Masonry, Ceramics, and Glass.

Image Description: Commutator grinding.—The heavy wear and tear that occurs between the commutator of an electrical dynamo machine and its brushes, due to the excessive friction that takes place between the two brushes and the commutator, frequently necessitates the removing of the whole armature of the dynamo machine to enable it to be fixed up in a …
