The X2 is not good at plunge milling. This is because there is too much flex in the machine. I have seen the whole head wobble when plunging into metal, and thats when I decided to lap the ways, and have a look at the Z axis. I measued deflection at the head to more then 0.3mm when I put about 40kg pressure on it. Now I have it down to 0.1, and it's all in the connection between the collumn and the base now.
If you have enough room for it, try not to plunge directly into the material, but make a linear movement on 2 axis (Z and X or Y) or a ciruclar interpolation with Z feed. |
