GREATER ACCURACY, SHORTER CYCLE TIME, LOWER COST Cogsdill Automatic Recessing Tools will save you time and money.Cycle time is reduced from minutes or hours to seconds . The precision is built into the head so that grooves and recesses canbe machined with exceptional accuracy and repeatability . The Automatic Recessing head changes the operational direction by90˚(i.e., axial spindle motion is converted to radial cutter movement).Recessing operations can be performed on a variety of machines,even on a drill press.

AUTOMATIC RECESSING The AR Series Automatic Recessing Tool is made up of three basic components:head, cutter, and pilot. The head is usually standard and consists of shank and tool body. All cutters and pilots are manufactured to suit your application. AR 16 Recessing Head > 5 size="-2">

AUTOMATIC RECESSING Illustrated below is the basic operating principle for AR , ARSP and ARX RecessingHeads. The head type shown below is the AR model. > The tool is rotating in a machinespindle. The spindle is lowered,and the tool moves into position. When the spindle is retracted, pressure is relieved, and the tool is withdrawn from the bore. The cutter retracts and returns to its starting position. The piloted bearing absorbs both thrust and rotation. It remains stationary in the bore of the workpiece, under load, until the cutter is fully retracted, thereby preventing scoring of the...
