In this way about 45 min-utes are required to slot the commutator of a GE-1000armature. The wheel press has been cleverly adapted for straight-ening bent axles. A bent car axle first is mounted on aspecial truck which has a regulating wheel to hold theaxle firmly in position. The distorted section is thenchalked off and the truck and axle placed at right angles to the wheel press, as shown on this page.

Thepressure is not exerted directly by the piston face, as mightbe supposed from the illustration, but through an insertedforging shaped like the frustum of a pyramid.
