Stone Commutator Grinding

Begin grinding by radially feeding the stones lightly against the commutator. Then, slowly move the carriage back and forth longitudinally across the surface. When the cutting action of the stone ceases, again feed the stone lightly against the commutator and continue grinding. Use care to make a light cut and to avoid chatter.

With these stones, it is not necessary to take a machine out of service to resurface its commutator, thus production time is saved and time-consuming major overhauls can be prevented.These are unmounted stones (no handles). There are advantages of grinding over turning a Commutator.

The Martindale Chain-Drive Commutator Grinder is a departure from previous designs, in that friction has been reduced to a minimum. Grinding dust has little effect on the operation. Two or three turns of the crank will move the carriage from one end of the bed to the other. The operator can “feel” the stone cut, and how fast to feed it.

A commutator or slip ring surface can be reconditioned in any one of seven ways, although other methods have been used in emergencies. The recognised and approved techniques are listed below in order of preference: 1. Turning with a diamond tipped tool 2. Turning with a tungsten carbide tipped tool 3. Grinding with a rotating wheel 4.

When fitting a full set of carbon brushes on a machine, it is very important to bed the brushes to assure a full contact area with the commutator or slip ring to avoid overloads. There are few ways to bed carbon brushes, the most common is with a Brush Bedding Stone in which case the particles of soft grinding stone will grind the brushes to a ...

To achieve this proper roughness, the commutator or the slip ring has to be ground after machining with a medium grinding stone such as P/N 90623N. If you wish to work without dismantling the machine, rather use a grinding stone with a handle.

Items having such mounting facilities as a fixed spindle, a threaded insert, or an arbor hole are designed for mounting on a grinding machine, tool chuck or mandrel. Items without mounting facilities are designed to be secured in a wheel holder by means of spring clamps. RFQ: Stone,commutator Surfacing: 5345-01-512-8942

A Commutator stone should be as long as will work freely between adjacent brush sets, and should also be twice as long as the width of the largest flat spot. This latter requirement may occasionally make it necessary to remove one brush-hold-er stud during the grinding, to prevent commutator ridges from wearing grooves in the stones.

If the concentricity of the commutator is not within tolerance, corrective action is indicated. The preferred method of making the commutator concentric is to send it to the motor shop and have it turned on a machine lathe. In the absence of this tool, the second preferred method is to use a grinding stone and to turn the commutator.

Begin grinding by radially feeding the stones lightly against the commutator. Then, slowly move the carriage back and forth longitudinally across the surface. When the cutting action of the stone ceases, again feed the stone lightly against the commutator and continue grinding. Use care to make a light cut and to avoid chatter.
