Automatic back spot face tool

The wing automatically folds into the pocket on coming in contact with the job in anti-clockwise rotation. Tools for this range of back spot facing are generally with HSS wings and feed rates of 0. For the rest, 0. Cutting parameters depend on machine condition, clamping rigidity, hardness of job etc. These are indicative parameters. Actual parameters are to be established only by trial and error. Please use this only as a reference to make CNC programs for your machines.

The parameters like feeds and speeds need to be manipulated as per your requirement. Press the pivot pin in the bore, provided on the tool shank. Position the wing in the pocket through the pivot pin. Screw on the pivot screw through the tapped hole till its point enters the cone, provided in the bottom of the wing.

Tighten the pivot screw till the clearance between the pivot pin and pivot screw is just sufficient for the wing to freely swing in and swing out of the pocket, at the same time avoiding any axial and radial play.

Lock this position by tightening the lock screw through the aluminum binder. Enter a few key inputs to find out.

Save Time, Decrease Cycle Time.

Features Extreme reliability of part processing, due to a friction-type clutch that mechanically opens and closes the cutting blade. Can perform heavy interrupted cuts, with cutting blades that are mechanically held open during cutting. Utilizes the part hole to support the tool while cutting, enabling the operator to run the Autofacer at carbide speeds and feeds even at long length-to-diameter ratios.

Available in many different configurations, depending upon your application needs. Once through, the wing automatically opens up into the cutting position. When rotating clockwise, it can begin back spotfacing. When finished, simply feed the spindle until the wing is clear of the workpiece and then, rotating anticlockwise, retract the tool.

The folding wing enables you to machine several otherwise inaccessible surfaces in one smooth motion. Global specialists in gundrill and BTA deep hole machine manufacture, CNC single and multi-axis purpose developed turnkey machines to meet customer requirements.
