Could be anything... quick guesses... 1) Mill is out of tram 2) Not locking the Z 3) Tool holder is worn/broken/incorrect. --- End quote --- Erm, 1) No idea what that means? 2) No idea what that means either. 3) It is new, but I honestly don't but I am doubting worn or broken, incorrcet, I would hope not, but again, I dont know :( |

Just noticed you are using the drill chuck to hold endmills. STOP! get the correct holder. Are you locking the Z? --- End quote --- The problem is, is I have no idea if its good, bad or indiffernt, and have no idea on peoples thoughts on buying the cheapest you can find. To me the spec seemed higher than some more expensive ones which is why I went for it. Its nice to hear that it can be good :) What is the "correct holder"? The "Z" ??? |

Agreed that more info is required, but when I first read it I wondered if maybe you're using an end mill and the end mill is being pulled out of the chuck due to the inherent cutting forces involved. I will admit that I've used an end mill in a drill chuck before, but it is definitely not something you want to make a habit. -Sparky |

Sorry... hit post before I finished. You need to get a collet setup or and end mill holder for you mill. The drill chuck cannot take the forces of lateral movement. It wasn't designed for that. Something like this or Also, are you locking the Z axis when you are making cuts? I know you are fairly new to machining. When I started, I got a couple of videos from these guys: SwarfRat Helped me a lot! You mmight want to consider getting some. Since they are here in the US, if you have issues getting them, I may be able to help you out. Eric |

OK! Tram. When a mill is in tram, it means the column is square to the table. Left and right AND front and back. A few links ONE and TWO. There should be a little lever on the side of the mill column. When you tighten it, it locks the head in place. The Z axis is the up and down movement of the mill head. |
