What does the machining center do with the Kong Shi's empty cutter slot?
Many parts have a knife back slot. Can fathom in design practice.
Of course, the need to go through the grinding parts are often design escrape, external thread will appear escrape, convenient tool exit, mainly to accommodate the cutting tool in a state of no cutting force under the knife.
The empty cutter groove is the cutter slot, which is mainly at the tail end of the blind hole and thread hole, in order to ensure the effective length and the processing time of the machined hole (screw hole)
