milling nylon

How do you prevent burr's from forming when machining this stuff.All I have is standard carbide endmills for cutting steel.It is just a spacer for and overmolded part to prevent deflection during the molding process.And like usual they need it yesterday.Also what type of cutting params?Climb milling?Conventional milling?

the material is nylon

Climb cutting and coolant will help.

If you can stand it, slightly round the corners of your endmill. Sharp HSS with a slight corner round works well also. +1 on the coolant

+1 to that

 

very sharp tool, avoid 4-flute carbide

Cool I will see what I have for HSS.

Router bits also work well.

 

A few years back we used some end mills made for cutting plastic that worked great. Don't remember what they were called, but they looked like a single fluted router bit.

+1 on the single flute cutters.

 

You have to cut the burrs off with a knife (Xacto), do not try to sand or file.

Be careful using coolant, nylon can swell in water !!

Ceramic scrapers are brilliant for deburring, chamfering etc plastic

I roughed with carbide +.05 p/s (thin wall standing ribs) with carbide 4fl left burrs.Then I z level finish with 4fl hss shp with and edge break haulin no burrs!!Worked great thanks for all the input guys
