The think about a drag knife is that you have to use special path planning for corners to make the knife swivel. These knives are mostly used in the sign-making industry to cut colored vinyl. Either the vinyl makes the letters of a stencil for paint. Many of these knives are designed to replace

I think you can just run a single pass through with a ballnose for a timing belt. Pretty sure that's for htd belts which are the most accurate and quite. I run T5 belts or t8 belts can transmit more torque On Sat, Jul 25, 2020, 7:04 AM John Dammeyer wrote: > What's the quietest profile/size

What's the quietest profile/size belt for driving a spindle with 2HP up to 3000 RPM. I recall someone saying the round groove is the best for this. Since we've been talking about gear cutters are there special cutters for that belt profile available? Thanks John ___
