Roger you kinda guessed it.. this is for a 4th axis for my cnc machine No rubber seals on this one yet as its just the 3 component gear set without bearings in which I will makeup a spindle for...

I wouldn't mind forking out some money for it but just not what I was quoted. I did find a supplier for the one of the other types but its not what I was recommended. ...

Thanks Andrew, sadly it needs grease. Where are the rubber parts?

A while back I got myself a harmonic drive off ebay ..actually a new one for dirt cheap. It was from a new other DENSO robot so I asked them what grease they used for it and apparently this stuff...

I have probably one of the oldest existing EMCO lathes that I am refurbishing and have a problem identifying the headstock spindle thread if anyone who has any more knowledge about spindle threads or...

Faunc should work with mach3

I wonder how much this guy wants for his post processor or if anyone is finally wiling to share it. Ill attempt to write one again myself for a basic 4 axis mill such as the grizzly or bf20l and...

I decided to try creating a new milling operation using the option "internal within solidworks part". Now when ever I open up the part without Solidcam I get the message choose part. I can not...

I'm using a 12mm 3 flute high helix rougher, a 6mm ball nose and a 3mm ball nose with 3 separate passes to get a very fine finish. The mill can run faster rpms and feeds but I find I get a resonance...

I have been working on a model for quite a while trying to figure out how I might go about making a fixture plate for it. I have a g0704 style mill(bf20l).

I have an image attached of how I was...

I used the SPI calculator to make the distance calculations, But I noticed that there is a few steps before the ball screw engages. Also my ball screw has a little backlash but not much I think .02mm

Thanks Paul for educating me, I wasn't even aware that they are referred to as idlers. Is one side enough or would I gain a more even tension by placing them either side?

I am looking at the idea of making some improvements to my belt drive setup for the x z and z of my mill. So far I have a pretty standard setup and it functions well with about .05/.07mm backlash...

this is a bit late but just in case someone is reading I also had problems with the a vertex table but mine was more due a sag when mounting hotizontal. By this I mean when trying to tighten the...

I just finally finished my HFFB today and I must say Im totally blown away just how well it works. I was using WD40 air blasts and a vac before this(needed an extra arm) and all I could manage was...

I don't have any big vices on my machine and I usually leave the table in the middle when I'm done.

I wont get a chance to re measure with locked x gibs as Jess suggested until Thursday...

My longest parts are around 16" and in the worst case scenario a 2 sided part can be out by .2mm or 0.0078"
I probably wont start with my mill when I learn the scraping:) I have an old abused enco...

You put allot of work and thought into making the bf20 something other than cheap Chinese garbage:) I have one and I'm seriously considering doing what you did with the linear rails because even...

Hi all,
I have a BF20L / G0704 (l for long table) that I bought in Germany and had pre converted to CNC. Upon tweaking the X axis I noticed quite some variations in the tables surface in...

on my larger bf20l table I get about + .05mm (.0019") on either side due to the gravity of the table..even though i have my gibs pretty tight. I wish more people would do some how to videos about...

Hoss do you have any more details on where you ordered the bf30 motor your using?

Just going back a moment to what way oil you use or actually any of you use. I got in contact with Optimum this week via email and a rep told me to use Ph neutral oil that wont go hard, he recommend...

Hey MaxMekker is there any chance you can upload that 4th axis post for solidcam to mach3?
Looking forward to giving it a go on my new vertex RT:)
Cheers

Hi all,
I am starting to move from making wax prototypes to using Aluminium to mill robot parts and I am a little stuck with deciding if I can use the 6060 grade on my CNC machine.
To be...
