Tim, Thank you - Later this week I'm going to give it another try. :beer: DaveH |
| jim:
i've machined a lot at work, slow and steady is the way. sharp tools and time work best |
| DaveH:
Jim, Thanks, If I may - what tools do you use HSS / Carbide With respect to steel do you use a faster or slower spindle speed? :beer: DaveH |

I used to do some bits for racing cars - until I found how notch sensitive and gall sensitive it is. Horrible stuff and actually potentially very dangerous if one is not certain of what one is doing - in stressed or critical applications. The trick I always found when taking small cuts is the feed rate. It does worrk harden easily, so whilst speeds were never an issure for me (a one off maker not a maufacturer) I found one had to stop it rubbing in any shape or form. Been a while now, - thank heavens, but a relativley high feed was always a lot more imortant than speed - and if possible, don't take small fine cuts! If it is a stressed application, its important (as in VITAL) to radius all corners, and if screw cutting to use a radiused tip. |

Totally agree with mgj. Where I used to work they were looking into machining some high end Ti, the torque required was off the scale, with machine, cutter, and set up rigidity being absolutely vital. cheers bp |
