what is the tolerance? what kind of surface finish are you looking for?

Something to consider. When I draw my parts in cad (for example a pocket with .125" radii in the corners.) If I intend to use a 1/4" endmill for finishing, (and if tolerances will permit) I will draw...

Inserting hardened buttons, and building fixtures from steel is the way a production fixture would be designed. However, for your small run fixture, and to keep cost down, aluminum is practical....

This is common sense. If anyone out there invests in a new spindle, installs it, and lays the whip to it right out of the box, you are on your own. C.M.I.'s reply makes it seem like a "run in" is...

What are you refering to when you say "burn it in". Is this a long gentle acceleration to warm up the spindle, or something aggressive (like it sounds)?

Are your parts large and heavy? Stainless, Titanium, Alloy steel, etc.
Go with the box way, High torque/HP spindle. Cincinnati wins this one.

Lots of aluminum parts and small run prototype work....

Is the cumulative number (say A84000) stored in a parameter? (say #xxxx)
Couldn't you zero this parameter by programming

N1000 #xxxx = 0.
N1010 M30 ?

And if the Haas...

Ever since our IS department set up my new workstation I no longer have access to the content center. We have a network licence. The IS guy's and gal's are pretty sharp on computer networking but...

I use Inventorcam and I am quite pleased with its results. I have used surfcam, bobcad, mastercam, delcam powermill, and featurecam. There are features in some of these that I miss, but then I learn...

That is cool, I thought most manufactures used solid wheels. Are you creep feed grinding with your plated wheels? Or are you just finish grinding an already roughed in shape (christmas tree)?Do you...

I haven't seen this type before, and If you use one like this I would do one of two things,

1. Make sure it is perpendicular to the work, The changing height would also change the position of the...

If you think this is cool, check out the "multitasking machines" with c and b axis. They don't stop there, adding turrets, sub-spindles, etc. Stama makes some really cool turn-mills, also check out...

OIL!
Wax may be another temporary solution.
Again the gunsmiths and gun-shops deal with this similar issue, they sell some good penetrating oils that last a long time.

What about black oxide? Or the bluing techniques gunsmiths use. Black oxide done to MIL spec is extremely durable, the m-16 machine guns are dragged through the mud, etc. and still polish up nicely....

Have you verified the machine is level? Make sure the weight is evenly distributed on all the pads. You need to verify the machines entire table is level at all extents of X and Y axis tavel. The...

Why isn't anyone making a pneumatic drawbar for R-8 or 30 taper knee mills? I have made some sketches to see if there is enough room inside the spindle quill, and I think it is quite possible. The...

the two sheave halves transmit their power through the straight sided spline that moves with the quill. the upper sheave half slides on a bushing (up and down)and is keyed to the lower half (so the...

what don't you understand? The handwheel turns a worm that drives a worm gear(2j547) for speed adjustment. This wraps a chain(2j572) around a pulley (2j514) that will pull down the clutch arm...

You didn't show the extra operation of drilling the holes in the side for the attachment of the yellow flag. Did you get your SMM-2 prewired for a 4th? With a rotary fixture you could complete this...

thanks Mactec, your help is well appreciated. I am surprised to hear these are a proprietary design. With all the joes out there with equipment in their garages, you would think that there would be...

thanks,
He is not looking at variable frequency drives. He needs an efficient and reliable digital phaze inverter for running his old 220V 3 phaze motors with The available residential 220V single...

I have a friend with a home machine shop. He has a bridgeport and a 7.5 horsepower lathe (both 3 phaze). He currently has a rotary phaze inverter, but is unhappy with the amount of power that is...

high positive sharp tools work best, If your facemill uses positive square inserts with a 45deg. lead angle... you are off to a good start. Good quality coated carbide(like Altin, Tialn.) will only...

check the simple things first. remove the way covers to see if it is something else inside. I don't think you should ignore a sound even if everything is within tolerance. If the noise is generated...

I can see you guys are making this work. There is always more than one way to kill a cat. Tool offset numbers should be entered as the tools length from spindle gage line, and the g5* Z value should...

you can't go wrong with a Mazak lathe. The conversational controll is the best out there, G-code is straight forward, they are robust and reliable.
I havn't had a nexus, but they are getting good...

I cut a lot of high temperature alloys on our VF3, however I do not do any quantities that anyone would call production. Get the gearbox option, and good luck, this is a very competitive industry, If...

If your machine produces a better finish when conventional cutting, it is probably due to something being loose.

I would like to see a vertical knee mill with features like a motorized spindle(compact), and a pneumatic drawbar like the ones in a typical cnc(electric selenoid operated by a push of a button) and...

MC,
Are these numbers generated by a machining calculator?
