Depending on the batch size, one method would be to rough turn the part first omitting the groove. Then chain drill the groove and then finish turn. The chain drilling should break up the swarf. If it was a large batch then I would knock up 2 or 3 grooving tools.

A component drawing should provide all the necessary info to manufacture the part. This may mean the machinist reaches for his calculator but he should be able to work out his intersection points with the dimensions provided. But, the machinist will know the programming language and be able to...

Have you tried TiCn slot drill instead? Try using parrafin too.

It looks like it has been made from solid bar, possibly in a rotary transfer machine. I worked in a hydraulic fittings factory and Ive seen an item similar to this where the threaded portion was machined and thread rolled into a round bar, a bore was machined in the side on 2nd op and a barb was...

Silver steel or D2 tooling steel would be more than good enough

Another way would be to use 1" square bar and mill it to size, use a 5mm end mill to rough out the slot, then use a ball nosed slot drill to finish the round section and then finally finish the 6mm part of the slot by opening it out with the 5mm end mill. Several passes would be needed with the...

If I was given the job of machining this up i would drill & bore one clevis from one side turn it around and setup for drilling & boring the other side but coming off the same machined datum faces as used for the other end. If aligned perfectly, I dont see why this wouldnt work. Only other way...

If I remember rightly about this material, you have to use carbide tips for alloy steel and when you machine it, never dwell or the material starts to harden i.e machine it like you mean to, dont mess with it.Also, slow down as this stuff seems to toughrn off if you get it too hot.

I'm assuming you are holding on the bar end and parting off the component when you've finished machining the outside/inside and the end. During the machining, just keep it nice and cool with the coolant.You may need to invest in a coolant cooler if you intend to do this as a regular job.Take the...

The idea of thread rolling is to work harden the material.Stress relieving after may undo the reasons for doing it in the first place.However, thread rolling is about cold forming a thread and since you have a semi hardened shaft you may consider locally heating the threaded area to soften the...

Truth is, years ago they used parrafin as a lubricant to prevent the chip welding to the tool.This is because parrafin dosnt globulise like water it actually spreads out over the tool face better and gets under the chip.However,in the uk parrafin is a no go at work and stinks so for one off type...

Successful entrepreneurs are proactive people and therefore take risks.Henry Ford apparently said 'if you think you can or you think you cant your right'.Trouble is you can't run before you can walk and I think in your case its gonna be about 'how you do it' not 'if you do it'.I think as...
