This Automatic Back Spot facing tool gives good performance and reduction in machine time by 50 to 90% as compared to manual tool setting methods. The back spot facing can be done at the same setting of the drilling operation and avoiding any separate setup for back spot facing or counter boring, back chamfering operation. This not only reduces the machining time but also increases the accuracy and repeatability of the operation.Operation :
The cutting edge swings in and out depending upon the direction of rotation of the machine spindle. The tool gets guided in the pre-drilled hole.
In anti-clockwise rotation, the back spot facing tool enters through the drilled hole. In clockwise rotation of the spindle, the tool opens up automatically and with feed it cuts.
After the back spot facing operation is complete, again the spindle rotation is reversed to anti-clockwise; the wing close into the pocket and the tool is pulled out of the hole. The entire back spot facing operation is over within a few moments, absolutely without any manual interruption at any stage of operation.
This is the only tool, which performs back spot facing operation automatically and without manual interruption. Therefore, for back spot facing operation, this is the most ideal tool in CNC machines, machining centers, SPMs with auto-cycle. When used even in conventional machines like radial drills, milling and boring machines, this tools saves considerable time.Features
