Newall B60 all day long too many gimmicks you won't use on Chinese units

perhaps you could increase the inertia of the spindle at low rpm by attaching a heavy weight to the end of the spindle like a heavy piece of steel turned up so it is balanced and start the cut when spindle gets to correct rpm Ray

a point to be aware of if you are using a carbide insert is not to drag it up a face i.e. the opposite way it cuts normally as the carbide is unsupported by the tool and will probably chip if you can get hold of a manufacturers catalogue they usually have a diagram of the direction the tool is...

searching for info on a broken machine and came across this catalogue for a 1965 machinery exhibition in Sydney found at users.beagle.com.au/lathefan it is an encyclopaedia of 1960s machine tools with some good photos of them it must have been an impressive exhibition with the number of machines...

Hi Everybody Thanks for the suggestions I have the materials to hand including a metal blacking kit left over from the whittle v8 I will turn up some scrap bits of brass and see how it turns out incidentally it is for a small desktop galleon style model cannon with about 2' long barrel Ray

Hi All Is it possible to get an antique weathered bronze cast finish on a brass machined part preferably without using too many chemicals Ray

Hi Scaffold poles are good for rolling m/cs on they will take a good weight also a crow bar or wrecking bar about 4ft long to lift it up off the ground to put rollers underneath and can be used to lever it forward by using it at back of m/c have used this method on a few including a Colc...

Hi ismael wish I had this sort of kit I would settle for a 30 year old Mazak QT8 to do some jobs I have pending at the moment

as a rule i would say no the power feed gives a more consistent finish for parallel turning or facing but with a 'delicate' tool thin groover etc feed by hand carefully the only time i change speed would be for tapping or external threading with diehead from the tailstock usually 50 rpm and feed...

kd Milling 920 rpm feed 100 mm/min, turn 500rpm .005"/rev with power feed anything from ally to stainless apart from titanium TA11 it works ok for me for a hobby job this is either hss or carbide Ray

If you take the top of the tool ie the bit with top rake as the reference point rather than a line through the centre of the spindle then the cutting edge will be either above or below centreline regardless of tool orientation as another example a tool mounted vertically such as a sliding head...

Hi Stephen Picture is a bench top grinder I use for sharpening cuttersit has an air spindle similar to Chuck’s which can be seen next to grindingwheel it takes 5C collets to hold cutter and runs on 80-100 psi for the airbearing as Bret stated a great way to grind end mills it will...

This looks very similar to a Swiss Agathon t&c grinder that I used in the 1960’s for brazed carbide tooling on a Tornos sliding head. If it is similar it will be a very good piece of kit when you get it up and running and very accurate. Ray

Thanks for that Dave I have already decided to get one the main reason being it should be easier to use than holding pc’s keyboard in front of machine for set up specially being able to use a mpg wheel Ray

does anyone have any experience of a vista cnc pendant please. i am thinking of getting one to run mach3 windows xp on Seig KX3 Ray

Had a similar problem with a KX3 which looks similar machine I was getting about .025” movement with the head at top of column moving it with light hand pressure. The column is held down with 4 M10 bolts with star washers which I thought was causing the problem replaced with 4 hitensile cap...

For a tailstock to engage sufficiently with the part it would have to exert pressure on the part thus forcing it on to the tool while still rotating as it nears the end of the cut as Tel said with the chance of it either breaking the tool or forcing it into the bar stock or damaging the part off...

these guys make some interesting large m/c centres & milling machines http://www.snkc.co.jp/english/index/index.htm Ray
