CNC - ongoing

Hi there,


Recently I made some progress in connecting new CNC parts in to one piece. I made a reinforcement, I mentioned about it before - 15 nuts to connect it to frame. It looks great, but time will show how it will work in future.

Next step was to place rails and carriages for Y and Z axis. I have screw them, and I will try to set as precisely as I can. I use indicator (I do not know exact name in English for that tool) and it looks like I have 0,01 mm precision. But frame is Aluminum, what will happen, when temperature will go up (it was 10 degrees of Celsius, when I have did all of it)

New CNC

Hi all

Recently I bought 12 pieces of 45 x 45 mm aluminum profiles. 500 mm long. I have some rails and linear bearings, some ACME screws and nuts. So I decide to build some new CNC. There will be some new stuff included in it, that I never try before:
- base made from epoxy granite,
- low speed spindle that I will build myself
Reason why I am building it is I want to get experience and get new skills.

Frame is almost build

T-nuts for 45x45 aluminum profiles.

Hi all,

last days I bought some second hand 45 x 45 aluminum profiles. I will build with them new CNC. To connect rails to them I have to use M5 screw. Normal metric nuts are to small, because profiles have 10 mm grove. I checked web and there were some special nut for this. But the prize is so big. For 30 nuts I have to pay more than for 4 m second hand profile. So I decide to made myself one. I measured the T grove in profile, took 20 x 5 mm flat and put it on CNC. And this is what I have:

 

T shape of this nut holder made it easy to slide inside a grove. Used normal M5 nut made it durability. It can be easy changed to bigger nuts. To compare some old special nut. Prize of it is equal to prize of this 3 that I made.

Table micro saw

Hi all,

In my workshop I have always some Plywood or MDF leftovers after cutting from plates on CNC. It can be used later, but you have to store it. Those leftovers are usually big and I am a little bit "lazy" one guy to cut them manually. So I took some time and search web for an inspiration, and found one. Micro Table Saw was my inspiration. And this is how I build one myself:
