Ksor, That's a really nice and fairly large, heavy duty mill you have. I'm not sure just what terminology is used in your country. Over here a mill that will allow the table to swing in a horizontal direction would be called a semi universal mill. That's a lot more work your doing than the average vertical mill would take. Well worth it I think for the extra capability you'll gain. Now you just need to find a universal dividing head to work with that new capability. I'd think your mill could easily turn my Atlas horizontal into chips. Pete |

>>Minor Oh, it's a very old one and I think that's why I have all this extra work ... right now I long for finishing the "update" and do some FUN stuff with it - I'm not sure I'm aware of all the new potential I got with the update - time will show it. |

Ksor, If your not too familier with what your new capabilitys will add to your machine then try Googling "Universal Dividing Head". I'd guess all that work is now done with CNC using a 4 axis machine. Long very low threads per inch for milling threads would be only one example, But it's a very handy addition that's quite rare for most manual mills built today. Machinery's Handbook has a large amount of pages devoted to the use of a universal dividing head used on a semi universal mill. Large drill bits were built on equipment like this too. Helical gears can be done also. In a simplified explanation, You install various gears on the end of the mills X axis leadscrew along with a banjo very much like a plain change gear lathe is set up for to do feeds and threading. This in turn drives the universal dividing head so you get both X axis travel and head rotation at the same time. Swinging the table horizontaly allows you to account for the helix angle. I bought a universal dividing head even though my vertical mill isn't a semi universal as it's still useable, But not as much as if I did have a semi universal mill. Your mill may be older, But I'd certainly love to have something like that. Pete |
