You can get a nice satin finish by polishing with a Scotchbrite pad ( try using the green side of a nylon pot cleaner as that will give you some idea of the finish )

You could talk to HPC Gears as they do a line of leadscrews (fairly good price) also they do specials if needed.

It could be that you are lubricating the cutter rather than letting it cut so you could be swaging some of the metal up to make the burrs.
I always cut dry on my Bridgeport when using carbide tips the alternative is to flood cool them with cutting oil (can be messy)

I have used Liberon Tourmaline in the past and got good results

Thread: A plastic valve

You could put a sacraficial bar in the hole and drill into that, so that no burr is raised
 
Thread: Super glue (cyanoacrylate)

Biggest rip off this year has to be fuel although crude oil has gone down in price we are still being ripped off Diesel at £7.00 a gallon.
Thread: Is it abuse if I...........?
01/06/2011 20:42:03
I was always taught never to reverse turn a reamer even when extracting it always turn the direction of cutting.
With a tap then yes reverse turn to break the chips

Thread: Emergency stop switch
23/04/2011 09:26:44
Your E stop circuit should also drop out the start / stop circuit so that when the E stop is reset you have to restart the machine by the start / stop button.
There are combined Start / stop / E stop units for sale these have a holding coil for the start button which automaticaly drops out when the E stop is applied or there is a power outage this stops the machine from self starting when the power comes back on line.
This is a legal requirement in the machinery directive

Thread: Stainless Steel
20/04/2011 11:03:18
As a thought you could try rolling the sheet (on a set of bending rolls ) on the long length and then cut the rounded end and flatten the front to suit

Mmmm, I know the old type of brake fluid worked but I don't know if the modern silicone based stuff touches paint work .

Thread: Building lathe/mill in cast of concrete?
07/04/2011 18:08:19
All the big column and booms 7m high x 9 m reach for welding, we used to supply for the wind turbine towers for offshore had concrete bases and all the attachment points for the slew ring 20 off 16mm and rail mount bogies were cast in.
We never had a problem and they all seemed very stable on dimensions
I think with some fore thought you could acheive a good base for a lathe. The main problem would be machining all the mounting point to get them level (depending on the size of lathe)
One last point we were not allowed to drill and and use expanding fixings i,e, rawlplug as it could be a stress point that had not been calculated for

Hi Martin
The speeds on the calculator site seem to be a bit slow or maybe they are for HSS as they are based on a tool life of 180 mins,
I know on my Bridgeport with a 40mm 3 tip carbide cutter on M.S. I'm running at around 450 - 600 rpm both on auto and hand feed and I get more than 3 hrs out of a set of tips

Hi Dixie I think this site may help

Thread: Steel, cuts like butter!
11/03/2011 08:15:15
Hi Nick what you are describing sounds more like Hydrogen cracking and the pre and post heating will help
Lead bearing free cutting steel will give rise to porosity.
Sulphur bearing free cutting steel will give rise to cracking
Both of these are not limited to thickness
Pre heating will in fact make matters worse as this will give rise to more dilution of the base material.
EN 3b is the material that is weldable and will give a good finish when machining

You could try your local spark erosion company as they should have some.
