Im trying to braoch a part with a haas lathe. the broach is torx t8. The broach ony goes in about .05 in before it brakes. i think the chips are building up. i drill it with a .069 drill. i have to go in at least .15 deep. i dont have a rotary Rotary Broach . i have dont bigger hex broach 3/16 with no problem but this is to small me me.

Cheaps? Do you mean chips?

Are you using M19 or C-axis positioning before trying to plunge the tool into the part? If yes, break it into several cycles for different depths, with a drill cycle in between each broach cycle to clear excess material.

sorry yes chips. . i didn't try m19. i was just reading that you can us it to in index it m19 p. i was thinking about doing it but was afraid to try it because i didn't know that haas could do that. But is there a away to read where it is at on the position, like a c-axis.

[txcncman]

If you do not have C axis option installed, you cannot read the spindle position.

but i could still use the m19 p ?

[txcncman]

Try it and find out.

thanks ill try tomorrow. also it would help if i wasn't using coolant I was reading it creates hydraulic lock.

[txcncman]

On the size broach and stroke you are doing, I do not think running coolant on the broaching op will help. Still use it on drilling though to flush chips.

works way better but i have one chip corner on the torx broach from the night before. We order new broach and a rotary broach. should i just live it alone and just use the broach be itself or use the rotary broach tomorrow.

[txcncman]

If you have enough depth on your broach, you might can resharpen.

[jz25180]

work great with out the rotary broach. it created to loose. and lots of chip buildup. what i did was drill broach re drill and broach to get my depth that i want. works great now.

Glad that worked out.
