Thread: Face mill size
22/07/2019 11:34:45

I have a similar sized mill but not the same make as yours. I use the face mill cutter to rough out you can use a higher RPM with a tipped face mill, but watch the swarf, and I have a home made fly cutter which is donkeys years old with a solid piece of carbide to give me a nice Finnish cut.

Fly cutter

Have you got a bench grinder as a green grit wheel will sharpen carbide tooling and you need a small radius to avoid the tip shattering.

Personally I would go for a smaller face mill perhaps a 25mm one and a fly cutter to finnish larger areas. Don't stress the mill too much.

Hi John welcome to the forum loads of information on here, if you look in the back threads there are lots of other people's efforts to give you inspiration. What are you looking at a rotary table or dividing head.

Thread: Black Oxide coating
20/07/2019 10:02:49

If you plate or other coat bolts and cap screws etc you can cause embritalnent or lower the tensile strength of items but there is no change to steel strength or structure with blackodising which is done by diping in to a caustic solution at 135 deg which causes a black coating Fe 3O4 which us rust preventative no change to steel structure. That is why Unbrako blackodise their cap screws.

Thread: air blast cooling for mill - solenoid control ?
12/07/2019 20:08:40

I would power it separately as it is useful to turn on and off whilst cutting or after cutting to clear swarf. You can also put a ventory to put a coolant or oil in the air quite easily controler by a hand controle valve.

Thread: Mains outlets with USB sockets - safety?
06/07/2019 07:14:50

If I use my phone charger to charge my tablet the tablet posts up a message that I should use the original charger as the tablet charger is rated at 2Amp and the phone charger is only rated at 0.7Amp. I wonder if other items use different Amp rated chargers and what these socket mounted chargers are rated at. Will they overheat if i charge my tablet in one.

Have you checked the carbon brushes as they are the first things to give a trouble and secondly the cables have a tendency to break inside the insulation as I have found out in the past. Check each cable end to end and move the cables about.

Hi where in the country do you reside I have some helicoil taps if you think it would help. You have to have enough metal round the thread to cut the oversized thread and when done it us just as strong and in alloy stronger.
