The Autofacer® is a tool that allows the machinist to reach through a hole and machine a circular feature on the back side of the part automatically. By circular feature we might mean a spot face, counter bore, countersink, chamfer, spherical radius, or some combination thereof. This is accomplished by folding the cutting blade into the shaft of the tool body allowing the tool to pass into the part. Once the tool has entered the part the cutting blade is mechanically opened and cutting may begin. The key design features of the Autofacer® are:
1) Friction type clutch that mechanically opens and closes the cutting blade ensuring high reliability of part processing
2) Cutting blades that are mechanically held open during cutting allowing Autofacer® to perform heavy interrupted cuts
3) Autofacer® body utilizes the part hole to support the tool while cutting. This enables the operator to run the Autofacer® at carbide speeds & feeds even at long length to diameter ratios.
Autofacers® cutting blades are available in many different configurations depending upon the customers’ application. Having a full service grinding department at our manufacturing facility in Fairport, N.Y. allows us to offer custom geometries on our indexable inserts and brazed carbide cutting blades. This means we can combine multiple operations into a single blade, thus maximizing time savings
There are various activation methods available for the Autofacer® depending upon the customer’s specific application. The key considerations for activation method selection are the machine tool being used and production quantities. The Application Engineers at Steiner Technologies, Inc will select the appropriate method to ensure optimum performance.
