![]() ![]() If you think about this you will see that it will produce a very slight convex on the face of the head which The vertical head is always tilted into the direction of travel so that there is no cut on the other side.I do get some movement as the table travels from one extreme to the other but this is very little. Never a problem, could not see a demarcation line where the second cut started. I have machined some longer than table stroke iron cylinder heads and repositioned head by sliding along the table as the heads are always on parallels. They last a long time before resharpening. Tools need to be kept sharp for good finish, but HSS for aluminium heads and brazed carbide for cast iron. I use a Narex VHU56 boring head as a flycutter - makes it very easy to adjust radius of cut. I've used a Cincinnati 314 Universal mill for the last 29 years to machine cylinder heads of all types. They have ALL been over the size of the head.Įither way I"m spending money. ![]() I just don't see that anyone has done it with a face mill anywhere i have checked and checked. If not, i'll try a fly cutter but i bet it's going to chatter with that 1/2 inch shank. I understand you may see the crossover line on the face mill, but you shouldn't feel it, and the tolerance to it should be almost negligible right? Or I can do 3 or so passes with a good quality 2.5 or 3 inch face mill. (I can run my spindle OK at 1500 rpm which appears to be ok.) I can use a big 200mm home made fly cutter someone who is good at making them will make it for me should I ask. I have a way now to fit up to a 3 inch face mill on my my CNC and remove an insert or two if necissary. (Honest)ĪND I just found a product to suit my machine.įigured I'd ask the same question in a more reasonable way then i did last time. I did scour the forum for the last 2 hrs.
