What are the NC tools? Tools commonly used in NC machining
The cutting tool of NC plane drilling machine is one of the preconditions to improve the machining efficiency. Its selection depends on the geometry of the workpiece to be processed, the material state, the fixture and the rigidity of the selected tool. Different tools have different uses in NC machining process, so what are the commonly used tools in NC machining process?2. Hole machining tool
Hole processing tools can be generally divided into two categories: one is to process holes from solid materials, commonly used are twist drills, center drills and deep hole drills; the other is the tools for reprocessing existing holes on the workpiece, commonly used are reamer, reamer and boring cutter, etc. For example, the structure of a standard high speed steel twist drill is shown below. The front end of the working part (cutter body) is the cutting part, which undertakes the main cutting work, and the back end is the guiding part, which plays the role of guiding the bit and is also the backup part of the cutting part.
