Technical Machinists, what is the technical name for this?

The difference between a mill and a drill is pull. On a mill, depending on the direction of cut you are "conventional" or "climb" milling. The direction of the helix is pulling the tool out out of the holder during climb milling. A mill's tool holder uses a drawbar (long bolt) to hold the tool holder in the the spindle (like an R8). Drill presses (and lathe tail stocks) don't experience pull and use Morse taper holders (relying on friction only to hold the adapter in) and will pull out of the spindle if you climb mill. Sure, the spindle bearings in a mill are sized to account for more side load but, the real difference is the drawbar. Mike

 

I love the smell of hot chips and oil in the morning.

 

I did too.............for the first twenty years!

 

If I go more than 2 or 3 days without turning or milling something, I start to suffer withdrawal symptoms!

 

I just re-patterned a set of wheels last night, boring for mag-shank lugs, and cutting flats for washers!

I am resisting the urge to go to the shop today. The wife says that working 7-days is not healthy.

 

I used to be that way. Surprised myself that once I retired (Toolmaker) I slowed down quite a bit.

 

I just putz. I taught Auto Mechanics and related subjects. My Dad was a machinist and I always envied his abilities carving on steel.

 

I folded the business up in 2019, I had a 30 year run making parts at home. I've been making chips for $$ since 1981. I still barter work on my car for machine time with one shop. I do things like remove broken bolts and studs.
