Understanding tool geometry and selecting the right tap for different workpiece materials can help take the anxiety out of tapping operations.Many machinists have learned to dread tapping. The story goes something like this. They press cycle start and then step back because the machine is in control. If the tap should hit bottom, too bad; the cycle must be completed—no feed-hold is allowed here. If the wrong feed rate was programmed, tough luck; the feed rate override is disabled. What else is there to do but cringe as the tap enters the hole?
For example, lowering the chip load can eliminate premature wear on a tap. Defined as the load induced on any one cutting edge, chip load is typically controlled by altering the feed rate. As mentioned earlier, this is not possible when tapping but the chip load can be altered through tap selection.
OSG’s Hy-Pro tap is designed for vertical and horizontal CNC tapping. The VXL tap (left) has a fast spiral-flute design for vertical machining. The HXL tap, with a slower spiral to break up chips, is for horizontal machining.
