Quick Tip - Zero Cost Swiss Speed Increase?

When you are cutting thousands of parts on your Swiss Lathe, every second counts. It's always tempting to aim for better feeds and speeds through upgrades, but there are other options you might be missing. In this quick tip, Brad talks about how the chucking part of your process can be sped up.

Great idea!

Better tighten that guide bushing a lil more

[@user-us9fc2ze6o]

This is not ideal at all.Because it makes the end of the bar bigger. If the main chuck moves away from the guide bush, it will cause more vibration in the guide bush

We will try to do another update on this with more program detail - in this case, we are running a very thin part - so the distance from the guide bushing does not impact us but you are correct - for a different geometry, that could be an issue. The part is so quick and thin, we are saving time by not re-chucking every part, but doing it every 5 - the bar end is still very close to the optimal size because the 5 parts in 1 cycle are not very long - but good feedback, thank you.

This place is clearly lying to you, to cost your shop wasted time. It chuck's up close to the part, so the bar doesn't wander around. You will have inconsistent parts! So the time you save will be wasted running more parts.

The guide bushing is what keeps the bar steady in the cutting zone. He's absolutely right.
