Third set up for operations to perform front hub facing, rim facing and rim chamfering on 13 inch "Sheldon" gear head lathe equipped with cross slide quick change tool post, multiple tool bit holder and scroll chuck. Third set up average production rate 55 wheels per hour.
First operation. Mounting wheel blank machined in the second set up on chuck and starting lathe. The chuck is equipped with mild steel jaws that are machined in order to grip the flange of the wheel without marring the surface.
Second operation. Tandem facing of rim and front hub with brazed carbide tool bits mounted on tool holder mounted on lathe compound slide using lathe power cross feed. The carriage is moved to the left side carriage stop and locked and the power cross feed is engaged. Adjustment of the compound slide simultaneously controls the depth of cut of both tool bits.
