Tapping aluminum (or tapping on wood?)
I got some work done on re-mounting my Y-axis scale on my Sieg X3.
Instead of drilling into the cast iron, I'm mounting the scale to a 1.50" wide piece of aluminum. Milled a bit of a relief so the base will fit on the left side of the saddle. This way most of the swarf will stay off the scale. Now that the scale beam is vertical, it again helps keep the beam clean. Maybe I grabbed the wrong tap... I'll czech it tomorrow. I used a #25 for a 10x24 screw, but all the tap did was spin. All ready for tapping bliss, had the spring loaded tap guide pushing the tap down... If I grabbed a 10x32 tap, the hole would have been undersized (10x32 needs a #21). Do normal taps work in 6061 aluminum, or should I go to a thread-former? |

Tapping aluminum (or tapping on wood?)
Yes, normal taps work fine in Aluminum. Check to make sure you
grabbed the correct drill size, always measure tap drills before using. On Dec 15, 6:27 pm, Louis Ohland wrote: I got some work done on re-mounting my Y-axis scale on my Sieg X3.

Instead of making it work, I just unshipped the collet, put away the clamps and cleaned up my mill. I see that Windex is supposed to be a good tapping fluid for aluminum... Was looking on the web to see who handles Tapmagic in southern Wisconsin... When Beloit Machine Supply closed, there's not much machinist stuff around local... |

Be sure to use the correct cutting fluid. Ace sells some stuff in a white can with black letteribtg abd red trim. Makes the tap almost fall through. I think it is called Tap Magic. Get the stuff for aluminum. Bob AZ |

It would only make a difference in production. You can even use spit for Al. No, not kidding! Nick -- The lowcost-DRO: http://www.yadro.de |

Tax that, Governor Doyle! |

But, that's what kids are for. 4" of powder in Wisconsin. Tax that, Governor Doyle! Oh, I'm sure he's working on a way to do that. By the way a leaf blower works VERY well on the fluffy stuff we got overnight. |

Using a 10x24 tap, it threaded well. I used some LPS lubricant as
cutting fluid... I was at Ace today, and there's no cutting fluid by the taps. Some nuclear rocket scientist must have reorganized the store... or they must order cutting fluid... |

WD-40 works and is available almost everywhere. WD40, The Wonder Drug. g If you're going to use Tap Magic, make sure it's Tap Magic Aluminum. The older Tap Magic for steel (and maybe the newer stuff -- mine is old) will turn aluminum black, boil and bubble, and eat the threads away. Otherwise, it's just fine. d8-) Kerosene is the traditional tapping fluid for aluminum. But WD40 probably won't hurt. -- Ed Huntress |
