If you're machining nylon on a swiss machine I'd be more concerned with the material diameter than inserts. Nylon is soft you can blast through with any carbide insert but the material diameter can change by as much as .005 causing it to jam up in the guidebushing. I mic the material and try and find a bar that is close from end to end. I then add a guide tube in the main collet to keep the material from whipping around. That's another issue. Good luck. |
