Yes, another angle head thread

[mkd]

We cut allot of "G18" semi circles where center line is about Y axis kellered along X axis. I'm looking at getting a 45° head for our 3 axis dept because we run into allot of situations with tiny (.060R) fillet radii at the bottom of walls, running up said half-circles. 45 head would allow the use of fairly stubby endmills (band-aid 5axis solution).

 

questions / suggestions needed are:

1. is there a 45 head that can be easily swung 180° without losing more than .002-.004" accuracy? no re-indicating; i'm thinking of a spring loaded pin or just a custom anti rotation clamp on spindle. manual loading is acceptable.

 

2. what would be the preferred programming/ setup method for inexperienced operators? would you use a tool setter to obtain the radius and input that into Misc. values.. etc? It would be nice if all the operator had to do is set the TLO same as a tool directly in spindle.

TIA

One thing to think about in that situation is the longevity of the angle heady when doing 3d machining for any period of time The duty cycle of those things usually isn't very high.

good point I hadn't really considered. there would be some cycle time doing leftovers. At the least we would want to have a coolant nozzle hitting it...

 

this would be a pretty light duty application on urethane lasting minutes, not hours.

 

anyway if it wasn't already obvious with above explination, i would want to cut the right side with one program, flip the head around 180 and cut the left side with a second.

Operators are going to need training no matter what method you use.

Right angle heads are easier as you can use G43 in 2 planes with 2 different offsets to get the positioning correct.

As soon as you go non-orthogonal, I treat it like a 5-axis machine where the tool length and angle head gage length become part of the equation.

here is an interesting solution. It would allow hitting right and left sides with one tool change/ program. easier to program and setup too. Only have to worry about mismatch between vertical tools.

 

hmmm options...

FWIW,

 

The duty time and performance of a BIG-Daishowa is arguably the best in the industry.

When it comes to tooling, you get what you pay for.

good stuff indeed.

Have you looked at EL-tool coolant driven? (If you have TSC)

[mkd]

spindle indexing accuracy is no bueno, not to mention no coolant pressure.

So a HAAS?

Haha bummer dude.

This might be enough power for ya
