FILENAMES: magchuck1.jpg magchuck2.jpg magchuck3.jpg DESCRIPTION: These are pictures of a magnetic chuck on a grinder. Posted by Kenneth W. Sterling . The following description was provided: ================================================================= Magchuck1.jpg This is a pix of a grinder we use to "flatten" grinder knives for meat grinders which are used for making hamburger. This uses a 7" mag chuck, circular, with concentric rings and an 8" x 3" grinding wheel, straight sided. Magchuck2.jpg This is a picture of the grinder knife sitting on the mag chuck ready for grinding. The knife only gets a light touchup to flatten all four wings of the knife. Problem is that there is not much metal for the mag chuck to grab, and the knife has to be centered in the mag chuck for proper rotational grinding/flattening. Magchuck3.jpg This is a pix of the ID plate on the mag chuck indicating 90Vdc and model number along with the manufacturers name.
