A beautifully made, very high precision machine, the Wickman Optical Profile Grinder combines, in effect, the functions of a universal tool and cutter grinder, a fiftytoone pantograph engraver and a "shadowgraph" projection unit the latter having both a circular viewing screen and a microscope.
Development of Robotic System for 3D Profile Grinding and Polishing AT/00/012/AMP 3 For each sectional profile, five measurement points are taken from the concave side and five from the convex side. When the measurement points fall into the brazed area, an approximation is made to offset the measured points to the priortobraze airfoil surface.
Jan 04, 2014· Grinding Practices. Earlier generation rail grinders were fitted with fixed grinding motors that required many grinding passes to remove shortpitch and shortwave corrugations, and improve rail surface conditions. Today, modern rail grinding equipment can achieve the desired rail profile and surface condition in a single pass.
Dec 08, 2016· Infeed grinding — also called plunge grinding — is used to grind cylindrical parts with notches or complex shapes, such as gear shafts. Here, the workpiece rest blade needs to be tooled to match the shape of the part. The grinding and regulating wheels must be dressed to match the part's desired profile cut.
